Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION AND BASIS OF PRESENTATION Organization Oiltanking Partners, L.P. (“OILT”) is a Delaware limited partnership formed by Oiltanking Holding Americas, Inc. (“OTA”) on March 14, 2011, to engage in the independent terminaling, storage and transportation of crude oil, refined petroleum products and liquefied petroleum gas. Through its wholly owned subsidiaries, Oiltanking Houston, L.P. (“OTH”) and Oiltanking Beaumont Partners, L.P. (“OTB”), OILT owns and operates storage and terminaling assets located along the United States Gulf Coast on the Houston Ship Channel and in Beaumont, Texas. On October 1, 2014, Enterprise Products Partners L.P. (“Enterprise”) acquired OTLP GP, LLC (our “general partner”) and related incentive distribution rights (“IDRs”), 15,899,802 common units and 38,899,802 subordinated units from OTA and its wholly owned subsidiary, OTB Holdco, LLC (“OTB Holdco”) (the “Transaction”). As a result of the Transaction, Enterprise owns 100% of our general partner. OTA and its affiliates no longer have any ownership interest in us or our general partner. See Note 13 for further information. Through September 30, 2014, OTA owned and controlled our general partner. OTA is a wholly owned subsidiary of Oiltanking GmbH. Oiltanking Finance B.V. (“OT Finance”), a wholly owned finance company of Oiltanking GmbH, serves as the global financing division for the Oiltanking Group’s terminal holdings, including us, and arranged loans and notes at market rates and terms for approved terminal construction projects. Oiltanking GmbH and its subsidiaries, other than OILT and its subsidiaries, are collectively referred to herein as the “Oiltanking Group.” As used in this document, the terms “we,” “us,” and “our” and similar terms refer to OILT and its subsidiaries, where applicable, unless the context indicates otherwise. On July 19, 2011, we completed our initial public offering (“IPO”) of 23,000,000 common units, including 3,000,000 common units issued in connection with the underwriters’ exercise of their over-allotment option, at a price to the public of $10.75 per unit. Our common units are listed on the New York Stock Exchange under the symbol “OILT.” Through July 18, 2011, OTH and OTB were wholly owned subsidiaries of OTA. OTA and its affiliates contributed all of their equity interests in OTH and OTB to us on July 19, 2011, and in exchange, we issued an aggregate of 15,899,802 common units and 38,899,802 subordinated units to OTA and its affiliates and IDRs to our general partner. At September 30, 2014, OTA owned our general partner and related IDRs, 15,899,802 common units and 38,899,802 subordinated units. On November 22, 2013, we completed a public offering of 5,200,000 common units at a price of $30.83 per unit. The proceeds from the offering, net of underwriting discounts and other offering expenses, totaled approximately $154.3 million. In connection with the offering, our general partner contributed an additional $3.3 million to us to maintain its 2.0% general partner interest. On July 14, 2014, we completed a two-for-one unit split by distributing one additional limited partner unit for each issued and outstanding limited partner unit to all unitholders of record as of July 7, 2014. All references to unit and per unit amounts in this document and related disclosures have been adjusted to reflect the effect of the unit split for all periods presented. At September 30, 2014, we had outstanding (i) 44,228,692 common units and 38,899,802 subordinated units representing limited partner interests, (ii) a 2.0% general partner interest and (iii) IDRs. At September 30, 2014, OTA and its affiliates held 65.9% of all of our outstanding common and subordinated units (or a 64.6% limited partner interest), and other security holders held the remaining 34.1% (or a 33.4% limited partner interest). The limited partners collectively hold a 98.0% limited partner interest in OILT, and the general partner holds a 2.0% general partner interest in OILT. Basis of Presentation Our results of operations for the three and nine months ended September 30, 2014 are not necessarily indicative of results expected for the full year of 2014. In the opinion of management, the accompanying condensed consolidated interim financial statements reflect all adjustments, which consist only of normal recurring adjustments, necessary to state fairly the results for the interim periods. The condensed consolidated financial statements and the accompanying notes are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial statements and the rules of the U.S. Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures required by GAAP for complete annual financial statements have been omitted and, therefore, these interim financial statements should be read in conjunction with our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2013. All significant intercompany transactions and balances have been eliminated in consolidation. The preparation of our financial statements in conformity with GAAP requires management to use estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We base our estimates and judgments on historical experience and on various other assumptions and information we believe to be reasonable under the circumstances. Estimates and assumptions about future events and their effects cannot be perceived with certainty and, accordingly, these estimates may change as new events occur, as more experience is acquired, as additional information is obtained and as the operating environment changes. While we believe the estimates and assumptions used in the preparation of the condensed consolidated financial statements are appropriate, actual results could differ from those estimates. Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at a specified measurement date. Fair value measurements are derived using inputs and assumptions market participants would use in pricing an asset or liability, including assumptions about risk. GAAP establishes a valuation hierarchy for disclosure of the inputs used to measure fair value. This three-tier hierarchy classifies fair value amounts recognized or disclosed in the financial statements based on the observability of inputs used to estimate such fair values. The classification within the hierarchy of a financial asset or liability is determined based on the lowest level input that is significant to the fair value measurement. The hierarchy considers fair value amounts based on observable inputs (Levels 1 and 2) to be more reliable and predictable than those based primarily on unobservable inputs (Level 3). Notes receivable, affiliate are reported in the condensed consolidated balance sheets at amounts which approximate fair value due to the relatively short period to maturity of these financial instruments (Level 2). The carrying values of our fixed-rate debt obligations approximate fair value based upon borrowing rates currently available to us for loans with similar terms (Level 2). The carrying values of our variable-rate debt obligations approximate their fair values because the associated interest rates are market-based. See Note 6 for further details of our debt obligations. We believe our valuation methods are appropriate and consistent with the values that would be determined by other market participants. However, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers. Under ASU 2014-09, an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. This ASU also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. This guidance is effective for annual periods beginning on or after December 15, 2016. We are in the process of assessing the impact of this ASU on our consolidated financial statements.

At September 30, 2014, we had no short-term notes receivable outstanding.

In accordance with our partnership agreement, our common, subordinated and general partner interests are entitled to receive quarterly distributions of available cash. During the nine months ended September 30, 2014 and 2013, we paid quarterly cash distributions, of which $45.8 million and $34.8 million, respectively, was paid to OTA and its affiliates, including IDRs.

One of the directors of our general partner prior to the Transaction, David L. Griffis, is employed by and a shareholder of the law firm of Crain, Caton & James, P.C., a firm that provides legal counsel to us, as well as to OTA and certain of its other affiliates. Fees for legal services paid to Crain, Caton & James, P.C. for services provided to us totaled $1.0 million and $0.9 million for the nine months ended September 30, 2014 and 2013, respectively.

Agreement with Affiliates

On July 19, 2011, in connection with our IPO, we entered into a services agreement (the “Services Agreement”) with our general partner and OTNA, and subsequently amended the Services Agreement in December 2011, pursuant to which OTNA agreed to provide us certain specified selling, general and administrative services necessary to manage our business for an annual fixed fee, payable in equal monthly installments. We also agreed to reimburse OTNA for all operating expenses and all expenses it incurred as a result of our becoming a publicly traded partnership, including all operating expenses it incurred with respect to insurance coverage for our business, with such reimbursement obligations not subject to any cap.

In August 2013, the Conflicts Committee of the board of directors of our general partner approved a requested increase to the fixed fee charged to us under the Services Agreement to $18.8 million on an annualized basis to reflect higher selling, general and administrative expenses associated with expansion projects placed in service in 2013. These expansion projects included the Houston crude oil storage and pipeline expansion, the first phase of our Appelt storage facility and related pipeline connections, and incremental refined petroleum products storage at our Beaumont terminal. The fee increase was effective as of July 1, 2013.

On October 1, 2014, the Services Agreement was terminated in connection with the Transaction. See Note 13 for further information regarding our entry into a new Administrative Services Agreement with Enterprise and its affiliates.

At September 30, 2014, under the most restrictive terms of the covenants contained in the agreements governing our long-term debt, partners’ capital of $301.5 million was available for distribution.

OTH and OTB Notes

At September 30, 2014, we had three outstanding notes with OT Finance. Two of the outstanding notes contain loan covenants requiring OTB to maintain certain debt, leverage and equity ratios and prohibit OTB from pledging its assets to third parties or incurring any indebtedness other than from OT Finance without its consent. At September 30, 2014, no assets had been pledged to third parties. The loan covenants in these agreements require OTB to maintain certain Financial Parameters (as such term is defined in the note agreements), including: (i) a ratio of Stockholders’ Equity to non-current assets of 30% or greater, (ii) a ratio of EBITDA to Total Debt Service of 1.2 or greater and (iii) a ratio of Net Financial Indebtedness to EBITDA of 3.75 or less (as such terms are defined in the note agreements). At September 30, 2014, OTB’s ratio of Stockholders’ Equity to non-current assets, EBITDA to Total Debt Service and Net Financial Indebtedness to EBITDA were 82.7%, 9.4 and 0.42, respectively. At September 30, 2014, OTB was in compliance with all covenants under the respective note agreements.

In connection with the Transaction, on October 1, 2014, OT Finance assigned all of its rights under the note agreements to Enterprise Products Operating LLC (“EPO”), a wholly owned subsidiary of Enterprise, as the new lender. See Note 13 for further information.

OTH Loan Agreements

On May 16, 2012, OTH entered into a ten-year $125.0 million unsecured loan agreement with OT Finance for the purpose of financing the purchase of property, plant and equipment with a maturity date of December 15, 2022. At September 30, 2014, OTH had $125.0 million of outstanding borrowings under this loan agreement at a fixed interest rate of 4.55% per annum.

On June 26, 2013, OTH entered into a ten-year $50.0 million unsecured loan agreement with OT Finance for the purpose of financing the purchase of property, plant and equipment with a maturity date of June 30, 2023. At September 30, 2014, OTH had $50.0 million of outstanding borrowings under this loan agreement at a fixed interest rate of 5.435% per annum.

The loan agreements contain covenants restricting the ability of OTH to take certain actions without the consent of OT Finance, including incurring additional indebtedness, pledging its assets or amending its organizational documents. The loan agreements contain borrowing conditions and events of default, including events of default triggered by (i) OTH failing to satisfy the Financial Parameters and other covenants described in this paragraph after more than 30 days’ notice, (ii) OTH failing to repay borrowings under the loan agreements when they become due, and (iii) OTH ceasing to be controlled by Oiltanking GmbH. The loan agreements require OTH to maintain certain Financial Parameters (as such term is defined in the loan agreements), including: (i) a ratio of Stockholders’ Equity to non-current assets of 30% or greater, (ii) a ratio of EBITDA to Total Debt Service of 1.2 or greater, and (iii) a ratio of Net Financial Indebtedness to EBITDA of 3.75 or less (as such terms are described in the loan agreements). At September 30, 2014, OTH’s ratio of Stockholders’ Equity to non-current assets, EBITDA to Total Debt Service and Net Financial Indebtedness to EBITDA were 63.6%, 16.4 and 1.24, respectively. At September 30, 2014, OTH was in compliance with all covenants contained in the loan agreements.

In connection with the Transaction, on October 1, 2014, OT Finance assigned all of its rights under the loan agreements to EPO as the new lender. See Note 13 for further information.

OILT Credit Agreement

On November 7, 2012, OILT entered into Addendum No. 2 to its unsecured revolving line of credit agreement with OT Finance to increase the amount of the revolving credit commitment from $50.0 million to $150.0 million and to extend the maturity date from June 30, 2013 to November 30, 2017 (as amended, the “Credit Agreement”). From time to time upon OILT’s written request and in the sole determination of OT Finance (now Enterprise following the Transaction), the revolving credit commitment can be increased up to an additional $75.0 million, for a maximum revolving credit commitment of $225.0 million. Borrowings bear interest at LIBOR plus a margin ranging from 1.65% to 2.50% depending upon a leverage-based grid. Any unused portion of the revolving line of credit is subject to a commitment fee of 0.35% per annum. At September 30, 2014, OILT had $37.0 million of outstanding borrowings under the Credit Agreement at a weighted average interest rate of 1.83% per annum.

The Credit Agreement requires OILT to maintain, on a calendar year basis, certain Financial Parameters (as such term is defined in the Credit Agreement), including: (i) a ratio of Stockholders’ Equity to non-current assets of 30% or greater, (ii) a ratio of EBITDA to Total Debt Service of 1.2 or greater and (iii) a ratio of Net Financial Indebtedness to EBITDA of 3.75 or less (as such terms are defined in the Credit Agreement). At September 30, 2014, OILT’s ratio of Stockholders’ Equity to non-current assets, EBITDA to Total Debt Service and Net Financial Indebtedness to EBITDA were 67.9%, 2.6 and 1.16, respectively. At September 30, 2014, OILT was in compliance with all covenants contained in the Credit Agreement.

In connection with the Transaction, on October 1, 2014, OT Finance assigned all of its rights under the Credit Agreement to EPO as the new lender. See Note 13 for further information.

Summary of Changes in Outstanding Units

The following is a reconciliation of our limited partner units outstanding for the periods indicated:



	Limited Partner Units
	Common		Subordinated	Total

Limited partner units outstanding at December 31, 2013	44,099,802		38,899,802	82,999,604

Limited partner units outstanding at September 30, 2014	44,228,692		38,899,802	83,128,494

Unit Split

On July 14, 2014, we completed a two-for-one unit split by distributing one additional limited partner unit for each issued and outstanding limited partner unit to all unitholders of record as of July 7, 2014. All references to unit and per unit amounts in this document and related disclosures have been adjusted to reflect the effect of the unit split for all periods presented.

Distributions

Our partnership agreement requires that, within 45 days after the end of each quarter, we distribute our available cash (as defined in our partnership agreement) to unitholders of record on the applicable record date.

The following table details the distributions paid during or pertaining to the nine months ended September 30, 2014 (in thousands, except per unit amounts):



		Common and		General		Incentive				Distributions
	Date Paid	Subordinated		Partner’s		Distribution				per Limited
Date Declared	or To Be Paid	Units		2% Interest		Rights		Total		Partner Unit

January 21, 2014	February 14, 2014	$	19,505	$	415	$	827	$	20,747	$	0.235
April 21, 2014	May 14, 2014	$	20,542	$	443	$	1,145	$	22,130	$	0.2475
July 21, 2014	August 14, 2014	$	21,614	$	478	$	1,836	$	23,928	$	0.26
October 17, 2014	November 14, 2014	$	22,653	$	520	$	2,836	$	26,009	$	0.2725

Our partnership agreement requires that we distribute all of our available cash (as defined in our partnership agreement) each quarter in the following manner:


•	first, 98.0% to the holders of our common units and 2.0% to our general partner, until each common unit has received the minimum quarterly distribution of $0.16875 plus any arrearages from prior quarters;


•	second, 98.0% to the holders of our subordinated units and 2.0% to our general partner, until each subordinated unit has received the minimum quarterly distribution of $0.16875; and


•	third, 98.0% to all unitholders pro rata, and 2.0% to our general partner, until each unit has received a quarterly distribution of $0.1940625.

The general partner’s IDRs provide that if cash distributions to our unitholders exceed $0.1940625 per common unit and subordinated unit in any quarter, our unitholders and our general partner will receive, including distributions with respect to its 2.0% general partner interest, distributions according to the following percentage allocations:



	Total Quarterly Distribution Per Unit Target Amount	Marginal Percentage Interest in Distributions
	Total Quarterly Distribution Per Unit Target Amount	Unitholders	General Partner
Minimum quarterly distribution	$0.16875	98.0%	2.0%
First target distribution	above $0.16875 up to $0.1940625	98.0%	2.0%
Second target distribution	above $0.1940625 up to $0.2109375	85.0%	15.0%
Third target distribution	above $0.2109375 up to $0.253125	75.0%	25.0%
Thereafter	above $0.253125	50.0%	50.0%

Our general partner, as the initial holder of all of our IDRs, has the right, at any time when there are no subordinated units outstanding and it has received incentive distributions at the highest level to which it is entitled (48.0%, in addition to distributions paid on its 2.0% general partner interest) for each of the prior four consecutive whole fiscal quarters, to reset the initial target distribution levels at higher levels based on our cash distributions at the time of the exercise of the reset election. If our general partner elects to reset the target distribution levels, it will be entitled to receive a number of common units and a general partner interest necessary to maintain its general partner interest in us immediately prior to the reset election. The number of common units to be issued to our general partner will equal the number of common units that would have entitled the holder to an average aggregate quarterly cash distribution in the prior two quarters equal to the average of the distributions to our general partner on the IDRs in such prior two quarters.

If our general partner transfers all or a portion of the IDRs in the future, then the holder or holders of a majority of our IDRs will be entitled to exercise the reset election. Assuming our general partner holds all of the IDRs at the time a reset election is made, following a reset election, the minimum quarterly distribution will be adjusted to equal the reset minimum quarterly distribution, and the target distribution levels will be reset to correspondingly higher levels based on the same percentage increases above the reset minimum quarterly distribution as the current target distribution levels.

Subordinated Units

Through September 30, 2014, all of our subordinated units were owned directly or indirectly by OTA. On October 1, 2014, Enterprise acquired the subordinated units from OTA and OTB Holdco. See Note 13 for further information on the Transaction.

The principal difference between our common units and subordinated units is that in any quarter during the subordination period, holders of the subordinated units are not entitled to receive any distribution until the common units have received the minimum quarterly distribution of $0.16875 per common unit plus any arrearages in the payment of the minimum quarterly distribution from prior quarters. Subordinated units will not accrue arrearages.

The subordination period will end on the first business day after we have earned and paid at least: (i) $0.675 (the minimum quarterly distribution on an annualized basis) on each outstanding common unit and subordinated unit and the corresponding distribution on our general partner’s 2.0% interest for each of three consecutive, non-overlapping four-quarter periods ending on or after September 30, 2014; or (ii) $1.0125 (150.0% of the annualized minimum quarterly distribution) on each outstanding common unit and subordinated unit and the corresponding distribution on our general partner’s 2.0% interest and the related distribution on the IDRs for the four-quarter period immediately preceding that date, in each case provided there are no arrearages on our common units at that time. Since our IPO in July 2011, we have paid at least the minimum quarterly distribution on our common units each quarter. The subordination period is expected to end following our payment of the distribution for the quarter ending September 30, 2014, upon satisfaction of certain requirements in our partnership agreement. See Note 13 for further information on the subordinated unit conversion.

The subordination period also will end upon the removal of our general partner other than for cause if no subordinated units or common units held by the holder(s) of subordinated units or their affiliates are voted in favor of that removal.

When the subordination period ends, all subordinated units will convert into common units on a one-for-one basis, and thereafter no common units will be entitled to arrearages.

____________

(1)

Based on the amount of net income for the three and nine months ended September 30, 2014 and 2013, our general partner was allocated income associated with its IDRs. Under the two-class method, because our partnership agreement does not limit distributions to our general partner with respect to IDRs to available cash, we allocate undistributed earnings to our general partner utilizing the distribution waterfall for available cash specified in our partnership agreement. Cash payments made to our general partner and limited partners are determined in relation to actual distributions declared rather than the net income allocations used in the calculation of earnings per unit.

Equity-Based Awards (Notes)

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

EQUITY-BASED AWARDS

We have a long-term incentive plan, the Oiltanking Partners, L.P. Long-Term Incentive Plan (the “LTIP”), for employees, consultants and directors of the general partner and those of its affiliates, including OTNA, a subsidiary of OTA, who performed services for us prior to the Transaction. The LTIP provides for the grant of restricted units, unit options, phantom units, unit payments, unit appreciation rights, other equity-based awards, distribution equivalent rights and performance awards. The LTIP limits the number of common units that may be delivered pursuant to awards under the plan to 7,779,960 units. During the three months ended September 30, 2014, 129,290 restricted common units were granted under the LTIP to executive officers and independent directors of our general partner and employees of OTNA who provide services to us.

The restricted common units awarded are subject to restrictions on transferability, customary forfeiture provisions and graded vesting provisions in which one-third of each award vests on December 31, 2014, December 31, 2015 and December 31, 2016, respectively. Award recipients have all the rights of a unitholder with respect to the restricted common units, including the right to receive distributions on the restricted common units if and when we pay distributions to our unitholders. The term “restricted common unit” represents a time-vested unit. Such awards are non-vested until the required service period expires. Restricted common units are included in the number of units presented on our unaudited condensed consolidated balance sheet.

The restricted common units granted are accounted for as equity-classified awards. The fair value of equity-classified awards, net of allowance for estimated forfeitures, is recognized as compensation cost over the requisite service or vesting period. The fair value of the restricted unit awards granted to the independent directors of our general partner are also recognized as compensation cost over the requisite service period. A portion of the total compensation expense for the period ended September 30, 2014 was charged to OTNA and its affiliates.

The following table summarizes information regarding restricted common unit awards granted under the LTIP for the periods presented:



			Weighted-
			Average Grant
			Date Fair Value
	Number of units		per Unit (1)

Restricted common units outstanding at December 31, 2013	—		$	—

Forfeited	(400	)	$	48.05
Restricted common units outstanding at September 30, 2014	128,890		$	48.05

_______________


(1)	Determined by dividing the aggregate grant date fair value of awards by the number of awards issued.


(2)	The aggregate grant date fair value of restricted common unit awards issued during the nine months ended September 30, 2014 was $6.2 million based on a grant date market price of $48.05 per unit.

During the three and nine months ended September 30, 2014, we recognized compensation expense of $1.0 million, of which $0.1 million was included in operating expenses and $0.9 million was included in selling, general and administrative expenses.

The aggregate unrecognized compensation cost associated with restricted common unit awards was $5.0 million at September 30, 2014.

Since the restricted common units are participating securities, any distributions received by the restricted common unitholders are included in distributions to partners as presented on our unaudited condensed consolidated statement of cash flows. During the nine months ended September 30, 2014, the restricted common unitholders received a distribution of approximately $0.1 million.

In connection with the Transaction and in accordance with the change of control provisions in the restricted unit award agreements, on October 1, 2014, the restricted units fully vested. As a result, we recognized the total remaining compensation cost of the restricted common unit awards in October 2014. See Note 13 for further information.

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENCIES

Litigation

In the ordinary course of business, we may be involved in various claims and legal proceedings, some of which are covered in whole or in part by insurance. We may not be able to predict the timing or outcome of these or future claims and proceedings with certainty, and an unfavorable resolution of one or more of such matters could have a material adverse effect on our financial condition, results of operations or cash flows. Currently, we are not party to any legal proceedings that, individually or in the aggregate, are reasonably likely to have a material adverse effect on our financial condition, results of operations or cash flows.

Environmental Liabilities

We may experience releases of crude oil, petroleum products and fuels, liquid petroleum gas or other contaminants into the environment, or discover past releases that were previously unidentified. Although we maintain an inspection program designed to prevent and, as applicable, to detect and address such releases promptly, damages and liabilities incurred due to any such environmental releases from our assets may affect our business. As of September 30, 2014 and December 31, 2013, we have not identified any environmental obligations that would require an accrual in our condensed consolidated financial statements.

Commitments

We have certain short-term purchase obligations and commitments for products and services, primarily related to construction on our expansion projects. At September 30, 2014, we had commitments of approximately $25.0 million for the purchase of property, plant and equipment.

Effective May 1, 2014, we entered into two land leases with a third party covering approximately 58 acres and 30 acres.

Our liquid storage and transport systems may experience damage as a result of an accident, natural disaster or terrorist activity. These hazards can cause personal injury and loss of life, severe damage to and destruction of property, and equipment, pollution or environmental damage and suspension of operations. We maintain insurance of various types that we consider adequate to cover our operations and properties. The insurance covers our assets in amounts we consider reasonable. The insurance policies are subject to deductibles that we consider reasonable and not excessive. Our insurance does not cover every potential risk associated with operating our facilities, including the potential loss of significant revenues.

The occurrence of a significant event not fully insured, indemnified or reserved against, or the failure of a party to meet its indemnification obligations, could materially and adversely affect our operations and financial condition.

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS Enterprise Acquisition of General Partner and Limited Partner Interests On October 1, 2014, OTA and OTB Holdco sold all of their common and subordinated units in the partnership along with their interest in our general partner and IDRs to Enterprise for aggregate consideration of approximately $4.41 billion pursuant to the Contribution and Purchase Agreement. Immediately after the closing of the Transaction, Enterprise contributed all of its interests in our general partner and our common and subordinated units to EPO, a wholly owned subsidiary of Enterprise. As a result of the Transaction, Enterprise owns and controls our general partner and owns a 64.6% limited partner interest in us. OTA no longer has any ownership interest in us or our general partner. Proposed Merger On October 1, 2014, Enterprise delivered a letter to the Chairman of the Conflicts Committee of our general partner proposing to merge a wholly owned subsidiary of Enterprise with OILT (the “Proposed Merger”) at a ratio of 1.23 Enterprise common units for each outstanding OILT common unit. The terms of the Proposed Merger will be subject to negotiation, review and approval by the Conflicts Committee and the board of directors of the general partner of Enterprise. The Proposed Merger, if agreed upon, will also be subject to approval by our unitholders in accordance with our partnership agreement. We cannot predict whether the terms of a potential combination will be agreed upon by the Conflicts Committee or the board of directors of the general partner of Enterprise, or the timing of any transaction. Waiver and Assignment Agreements Relating to Indebtedness In connection with the Transaction, on October 1, 2014, we and our subsidiaries, OTH and OTB, each entered into a Waiver and Assignment Agreement with OT Finance, as the prior lender, and EPO, as the new lender, pursuant to which OT Finance assigned to EPO all of its rights under our Credit Agreement and OTH’s and OTB’s note agreements. All the terms and conditions in the Credit Agreement and note agreements remain substantially the same. Second Amended and Restated Limited Liability Company Agreement of the General Partner On October 1, 2014, EPO entered into the Second Amended and Restated Limited Liability Company Agreement of the general partner (“A&R LLC Agreement”) in EPO’s capacity as the sole member of our general partner. The A&R LLC Agreement updates the prior limited liability company agreement of our general partner with EPO’s address, and other ministerial changes to reflect EPO’s new capacity as the sole member of our general partner. Director and Officer Resignations and Appointments In connection with the Transaction, Kenneth F. Owen, Christian Flach, James Flannan Browne and David L. Griffis resigned from the board of directors of our general partner, effective as of the closing of the Transaction on October 1, 2014. The resignations were not a result of any disagreements between our general partner and the directors or on any matter relating to the general partner’s operations, policies or practices. Bryan Bulawa, Robert Sanders, William Ordemann and Michael C. Smith were appointed to the board of directors of the general partner, effective as of the closing of the Transaction on October 1, 2014. Mr. Bulawa was appointed as Chairman of the board of directors. The new directors were appointed pursuant to the Contribution and Purchase Agreement in connection with the Transaction. On October 6, 2014, Kenneth F. Owen resigned as the President and Chief Executive Officer of our general partner, Jonathan Z. Ackerman resigned as the Vice President and Chief Financial Officer of our general partner and Brian C. Brantley resigned as the Vice President, General Counsel and Secretary of our general partner. Also on October 6, 2014, Laurie H. Argo was appointed President and Chief Executive Officer of our general partner and Donna Y. Hymel was appointed Chief Financial Officer of our general partner. Termination of the Services Agreement Also on October 1, 2014, the Services Agreement with OTNA terminated in accordance with its terms due to the change in control of our general partner as a result of the Transaction. Administrative Services Agreement On October 17, 2014, we and our general partner entered into the Seventh Amended and Restated Administrative Services Agreement (the “Administrative Services Agreement”) with Enterprise and certain of its affiliates, including Enterprise Products Company, a Texas corporation (“EPCO”). The Administrative Services Agreement is effective as of October 1, 2014. The Administrative Services Agreement provides that EPCO or its affiliates will provide certain selling, general and administrative services and management and operating services to us as may be necessary to manage and operate our business, properties and assets (all in accordance with prudent industry practices). We will be required to reimburse EPCO for its services in an amount equal to the sum of all costs and expenses incurred by EPCO which are directly or indirectly related to our business or activities (including expenses reasonably allocated to us by EPCO). In addition, we have agreed to pay all sales, use, excise, value added or similar taxes, if any, that may be applicable from time to time with respect to the services provided to us by EPCO. EPCO will allow us to participate as a named insured in its overall insurance program, with the associated premiums and other costs being allocated to us. Tax Sharing Agreement Also on October 17, 2014, but effective as of October 1, 2014, we entered into the Tax Sharing Agreement (the “Tax Sharing Agreement”) with Enterprise in connection with the Transaction. The Tax Sharing Agreement provides for the allocation among Enterprise and its affiliates on the one hand, and us and our subsidiaries on the other hand, of all responsibilities, liabilities and benefits relating to any tax for which a combined return is filed for a taxable period on or after October 1, 2014. The Tax Sharing Agreement amended certain party and affiliate group terms under the prior tax sharing agreement assigned by OTA to Enterprise in connection with the Transaction. The amount of any such reimbursement is limited to the tax that we and our subsidiaries would have paid had we not been included in a combined group with Enterprise. Enterprise may use its tax attributes to cause its combined or consolidated group, of which we may be a member for this purpose, to owe no tax. However, we will nevertheless reimburse Enterprise for the tax we would have owed had the attributes not been available or used for our benefit, even though Enterprise had no cash expense for that period. Accelerated Vesting of Restricted Unit Awards As a result of the Transaction, all of the outstanding restricted units awarded pursuant to the LTIP immediately became 100% vested in accordance with the change of control provisions in the restricted unit award agreements. As a result, we recognized the total remaining compensation cost of the restricted common unit awards in October 2014. Technical Termination of Partnership for U.S. Federal Income Tax Purposes As noted in Item 1A, Risk Factors, of our 2013 Form 10-K, because we are treated as a partnership for U.S. federal income tax purposes, a sale or exchange of 50% or more of our capital and profits interests within a twelve-month period will result in a technical termination. As a result of the transactions consummated under the Contribution and Purchase Agreement, which occurred on October 1, 2014, we believe that we will be considered to have technically terminated as a partnership for U.S. federal income tax purposes on such date. The technical termination does not affect our consolidated financial statements nor does it affect our classification as a partnership or otherwise affect the nature or extent of our “qualifying income” for U.S. federal income tax purposes. However, the termination will, among other things, result in the closing of our taxable year for all unitholders on October 1, 2014, which will require us to file two tax returns for the 2014 calendar year and may result in a significant deferral of depreciation deductions that were otherwise allowable in computing the taxable income of our unitholders (because of the requirement that tax depreciation be restarted as if all of our assets are placed in service after the technical termination). In the case of a unitholder reporting on a taxable year other than the calendar year, the closing of our taxable year may also result in more than twelve months of our taxable income or loss being includable in the unitholder’s taxable income for the year of termination. The Internal Revenue Service (“IRS”) has announced a relief procedure whereby if a publicly-traded partnership that has technically terminated requests and the IRS grants special relief, among other things, the partnership may be permitted to provide only a single Schedule K-1 to unitholders for the two tax periods included in the year in which the termination occurs. We plan to make this request to the IRS. Subordinated Unit Conversion Upon payment of our distribution with respect to the third quarter of 2014, which is expected to be paid November 14, 2014, the subordination period with respect to the subordinated units will end upon satisfaction of certain requirements in our partnership agreement. On the first business day following such distribution, the subordinated units will convert into common units on a one-for-one basis. Upon conversion, Enterprise will own 54,799,604 common units, or approximately 65.9% of our outstanding common units.

Organization and Basis of Presentation Fair Value Measurements (Policies)	9 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at a specified measurement date. Fair value measurements are derived using inputs and assumptions market participants would use in pricing an asset or liability, including assumptions about risk. GAAP establishes a valuation hierarchy for disclosure of the inputs used to measure fair value. This three-tier hierarchy classifies fair value amounts recognized or disclosed in the financial statements based on the observability of inputs used to estimate such fair values. The classification within the hierarchy of a financial asset or liability is determined based on the lowest level input that is significant to the fair value measurement. The hierarchy considers fair value amounts based on observable inputs (Levels 1 and 2) to be more reliable and predictable than those based primarily on unobservable inputs (Level 3). Notes receivable, affiliate are reported in the condensed consolidated balance sheets at amounts which approximate fair value due to the relatively short period to maturity of these financial instruments (Level 2). The carrying values of our fixed-rate debt obligations approximate fair value based upon borrowing rates currently available to us for loans with similar terms (Level 2). The carrying values of our variable-rate debt obligations approximate their fair values because the associated interest rates are market-based. See Note 6 for further details of our debt obligations. We believe our valuation methods are appropriate and consistent with the values that would be determined by other market participants. However, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers. Under ASU 2014-09, an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. This ASU also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. This guidance is effective for annual periods beginning on or after December 15, 2016. We are in the process of assessing the impact of this ASU on our consolidated financial statements.
