Basis of Presentation and General Information [Abstract]
Basis of Presentation and General Information	1. Basis of Presentation and General Information Capital Product Partners L.P. (the “Partnership”) was formed on January 16, 2007, under the laws of the Marshall Islands. The Partnership is an international shipping company. The Partnership currently owns a fleet of eleven high specification vessels consisting of ten Neo Panamax container carrier vessels and one Capesize bulk carrier. Its vessels are capable of carrying a wide range of dry cargoes, as well as containerized goods under short-term voyage charters and medium to long-term time and bareboat charters. transaction with dss holdings l.p. On November 27, 2018, the Partnership entered into a definitive transaction agreement with DSS Holdings L.P. (“DSS”), pursuant to which the Partnership agreed to combine its crude and product tanker business (the “Tanker Business”) with DSS’s businesses and operations in a share-for-share transaction (the “DSS Transaction”). The DSS Transaction was completed on March 27, 2019. In connection with the DSS Transaction, among other things: the Partnership established a number of entities for the implementation of the DSS Transaction, including Athena SpinCo Inc. (renamed Diamond S Shipping Inc. or “Diamond S”); the Partnership spun off Diamond S, holding all of its 25 crude and product tankers, by way of pro rata distribution of the outstanding shares of common stock of Diamond S to the holders of the Partnership’s common and general partner units; DSS paid to the Partnership, or at its direction, a total amount of $319,651; the Partnership redeemed and retired all outstanding Class B Convertible Preferred Units at 100% of par value, translating into a total redemption amount of $119,502 (Note 10); the Partnership amended and prepaid an amount of $89,298 under the 2017 credit facility and fully repaid all amounts outstanding under the 2015 credit facility and the Aristaios credit facility; the aggregate amounts repaid were $146,517 plus accrued interest and breakage costs; the Partnership effected a reverse split of its common and general partner units, reducing the number of common units issued and outstanding from 127,246,692 to 18,178,100 common units and the number of general partner units issued and outstanding from 2,439,989 to 348,570 general partner units; the Partnership and Capital Ship Management Corp. (“CSM” or the “Manager”) agreed to terminate the commercial and technical management agreement, dated as of March 17, 2010, between them as all vessels covered by this agreement were spun off as part of Diamond S; and the Partnership and CSM agreed to amend the floating rate management agreement, dated June 10, 2011, between them to reflect that all tankers vessels owned by the Partnership were part of its Tanker Business which spun off would no longer be managed under this agreement. In accordance with Accounting Standards Update (“ASU”) 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity the assets and liabilities, results of operations and cash flows of the Tanker Business are reported as discontinued operations for all periods presented (Note 4). In addition all per unit data in these unaudited condensed consolidated financial statements has been retrospectively adjusted to reflect the impact of the one-for-seven reverse unit split the Partnership effected on March 27, 2019 in connection with DSS Transaction (Note 10). The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all the information and notes required by U.S. GAAP for complete financial statements. These unaudited condensed consolidated financial statements and the accompanying notes should be read in conjunction with the Partnership’s consolidated financial statements for the year ended December 31, 2018, included in the Partnership’s Annual Report on Form 20-F for the fiscal year ended December 31, 2018, filed with the U.S. Securities and Exchange Commission (the “SEC”) on April 26, 2019. These unaudited condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments considered necessary for a fair presentation of the Partnership’s financial position, results of operations and cash flows for the periods presented.

Significant Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies A discussion of the Partnership’s significant accounting policies can be found in the Partnership’s Consolidated Financial Statements included in the Annual Report on Form 20-F for the year ended December 31, 2018 (the “Consolidated Financial Statements for the year ended December 31, 2018”). Changes in Accounting Policies ASU 2016-02- Leases (Topic 842): The Partnership adopted this standard for the reporting period commencing on January 1, 2019 and elected the practical expedient under ASU 2018-11 for the vessels under time charter agreements. Furthermore, the Partnership applied the transition provisions of ASU 2016-02 at its adoption date, rather than the earliest comparative period presented in the financial statements, as permitted by ASU 2018-11. The nature of the lease component and non-lease component that were combined as a result of applying the practical expedient are the contract for the hire of a vessel and the fees for operating and maintaining the vessel respectively. The lease component is the predominant component and the Partnership accounts for the combined component as an operating lease in accordance with Topic 842. The Partnership applied Topic 842 with no significant impact on its financial statements and as a result no adjustment was posted in the Partnership’s opening retained earnings as of January 1, 2019. Please refer to Note 3 for further details.

3. Recognition of revenue from continuing operations

The following table shows the revenues from continuing operations earned from time and voyage charters contracts for the six-month period ended June 30, 2019 and 2018:

	For the six-month period ended June 30,
	2019	2018
Time charters (operating leases)	$ 54,234	$ 52,763
Voyage charters (accounted for under Accounting Standard Codification (“ASC”) 606)	$ -	$ 5,471
Total	$ 54,234	$ 58,234

For the six-month period ended June 30, 2019 all of our time charters revenue is accounted for under Topic 842. For the six-month period ended June 30, 2018 all of our time charters revenue is accounted for under ASC 840.

Time charters contracts

A time charter is a contract for the use of a vessel for a specific period of time and a specified daily charter hire rate, which is generally payable in advance. A time charter generally provides typical warranties and owner protective restrictions. The performance obligations in a time charter are satisfied over the term of the contract beginning when the vessel is delivered to the charterer until it is redelivered back to the owner of the vessel. The time charter contracts are considered operating leases and therefore fall under the scope of ASC 842 because (i) the vessel is an identifiable asset (ii) the owner of the vessel does not have substantive substitution rights and (iii) the charterer has the right to control the use of the vessel during the term of the contract and derives the economic benefits from such use. Revenues from time charters are recognized rateably on a straight line basis over the period of the respective charter. Under time charter agreements, all voyages expenses, except commissions are assumed by the charterer. Operating costs incurred for running the vessel such as crew costs, vessel insurance, repairs and maintenance and lubricants are paid by the Partnership under time charter agreements.

The transition guidance associated with ASC 842 allows for certain practical expedients to the lessors. The Partnership elected to not separate the lease and non-lease components included in the time charter revenue because the pattern of revenue recognition for the lease and non-lease components (included in the daily hire rate) is the same. The daily hire rate represents the hire rate for a time charter as well as the compensation for expenses for operating and maintaining the vessel such as crew costs, vessel insurance, repairs and maintenance and lubricants. Both the lease and non-lease components are earned by passage of time.

In addition, the Partnership reimburses the Manager and CGP for reasonable costs and expenses incurred in connection with the provision of these services after the Manager submits to the Partnership an invoice for such costs and expenses, together with any supporting detail that may be reasonably required. These expenses are included in “General and administrative expenses” in the unaudited condensed consolidated statements of comprehensive (loss) / income. In December 2015, the Partnership entered into an executive services agreement with CGP, which was amended in 2016 and according to which CGP also provides certain executive officers services for the management of the Partnership’s business as well as investor relations and corporate support services to the Partnership.

The aggregate amounts repaid were $146,517 plus accrued interest and breakage costs. The Partnership presents associated amounts of long-term debt outstanding as of December 31, 2018 and interest expense and amortization of deferred loan issuance costs for the six-month periods ended June 30, 2019 and 2018 relating to the Tanker Business contributed in the DSS Transaction within discontinued operations (Note 4).

In March 2019, in connection with the DSS Transaction (Note 1), the Partnership entered into a Deed of Amendment and Restatement agreement with its 2017 credit facility lenders. According to this agreement, the amended 2017 credit facility is payable in 19 equal quarterly installments of $7,703 beginning in April 2019 in addition to a balloon installment of $139,130, which is payable together with the final quarterly installment in the fourth quarter of 2023. All other terms and conditions remained unchanged.

During the six-month period ended June 30, 2019 the Partnership repaid the amount of $17,326 in line with the amortization schedule of its 2017 credit facility.

As of June 30, 2019 and December 31, 2018 the Partnership was in compliance with all financial debt covenants.

For the six-month periods ended June 30, 2019 and 2018, interest expense from continuing operations amounted to $8,426 and $8,715, respectively and the weighted average interest rate of the Partnership’s loan facilities was 6.0% and 5.2% respectively.

Financial Instruments	6 Months Ended
Financial Instruments	Jun. 30, 2019
Financial Instruments [Abstract]
Financial Instruments	9. Financial Instruments The Partnership follows the accounting guidance for financial instruments that establishes a framework for measuring fair value under generally accepted accounting principles and expands disclosure about fair value measurements. This guidance enables the reader of the financial statements to assess the inputs used to develop those measurements by establishing a hierarchy for ranking the quality and reliability of the information used to determine fair values. The statement requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories: Level 1: Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date; Level 2: Inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; Level 3: Inputs are unobservable inputs for the asset or liability. (a) Fair value of financial instruments The carrying value of cash and cash equivalents and restricted cash, which are considered Level 1 items as they represent liquid assets with short-term maturities, trade receivables, due to related parties, trade accounts payable and accrued liabilities, approximates their fair value. The fair value of long-term variable rate bank loan approximates the recorded value, due to its variable interest being the LIBOR and due to the fact the lenders have the ability to pass on their funding cost to the Partnership under certain circumstances, which reflects its current assessed risk. The Partnership believes that the terms of its loan are similar to those that could be procured as of June 30, 2019. LIBOR rates are observable at commonly quoted intervals for the full term of the loan and accordingly the bank loan is considered Level 2 item in accordance with the fair value hierarchy. (b) Concentration of credit risk Financial instruments which potentially subject the Partnership to significant concentrations of credit risk consist principally of cash and cash equivalents and trade accounts receivable. The Partnership places its cash and cash equivalents, consisting mostly of deposits with a limited number of creditworthy financial institutions rated by qualified rating agencies. Most of the Partnership’s revenues were derived from a few charterers. For the six-month periods ended June 30, 2019 and 2018 there were two customers that each accounted for more than 10% of the Partnership’s revenues from continuing operations for each period. The Partnership does not obtain rights of collateral from its charterers to reduce its credit risk.

Partners' Capital

10. Partners’ Capital

As of June 30, 2019 and December 31, 2018 the Partnership’s partners’ capital was comprised of the following units:


	As of June 30, 2019		As of December 31, 2018 (adjusted for the March 2019 reverse split)
Common units		18,178,100		18,178,100

Preferred units		-		12,983,333
Total partnership units		18,526,670		31,510,003

On March 27, 2019, in connection with the DSS Transaction, the Partnership effected a reverse split of its common and general partner units, reducing the number of common units issued and outstanding from 127,246,692 to 18,178,100 and the number of general partner units issued and outstanding from 2,439,989 to 348,570. In addition, the Partnership redeemed and retired all outstanding Class B Convertible Preferred Units at 100% of par value, translating into a redemption price of $116,850, and paid to Class B Convertible Preferred Units holders the pro-rata dividends for the period from January 1, 2019 to March 27, 2019, which amounted to $2,652. The difference between the carrying amount of Class B Convertible Preferred Units at the time of their redemption and their redemption price amounted to $6,344. The difference was considered as deemed dividends to preferred unit holders and was presented as income attributable to preferred unit holders in the Partnership’s unaudited condensed consolidated financial statements.

Details of the Partnership’s partner’s capital are discussed in Note 12 of the Partnership’s Consolidated Financial Statements for the year ended December 31, 2018.

During the six-month periods ended June 30, 2019 and 2018, the Partnership declared and paid the following distributions to its common and preferred unit holders:

Net Income Per Unit

11. Net Income Per Unit from continuing operations

The general partner’s and common unit holders’ interests in net income are calculated as if all net income for periods subsequent to April 4, 2007 were distributed according to the terms of the Partnership’s Limited Partnership Agreement (the “Partnership Agreement”), regardless of whether those earnings would or could be distributed. The Partnership Agreement does not provide for the distribution of net income; rather, it provides for the distribution of “available cash”, which is a contractually defined term that generally means all cash on hand at the end of each quarter after establishment of cash reserves determined by the Partnership’s board of directors to provide for the proper resources for the Partnership’s business. Unlike available cash, net income is affected by non-cash items. The Partnership follows the guidance relating to the Application of the Two-Class Method and its application to Master Limited Partnerships and considers whether the incentive distributions of a master limited partnership represent a participating security when considered in the calculation of earnings per unit under the Two-Class Method.

The Partnership also considers whether the Partnership Agreement contains any contractual limitations concerning distributions to the incentive distribution rights that would impact the amount of earnings to allocate to the incentive distribution rights for each reporting period.

Under the Partnership Agreement, the holder of the incentive distribution rights in the Partnership, which is currently CGP, assuming that there are no cumulative arrearages on common unit distributions, has the right to receive an increasing percentage of cash distributions after the minimum quarterly distribution. The Partnership also excluded the effect of the 12,983,333 Class B Convertible Preferred Units in calculating dilutive Earnings Per Unit (“EPU”) for the six-month periods ended June 30, 2019 and 2018, as they were anti-dilutive.

As of June 30, 2018 the Partnership excluded the effect of 77,857 (adjusted for the March 2019 reverse split) non-vested unit awards in calculating dilutive EPU for its common unitholders, as they were anti-dilutive. The non-vested units were participating securities because they received distributions from the Partnership and these distributions did not have to be returned to the Partnership if the non-vested units were forfeited by the grantee. All awards vested on December 31, 2018.

The Partnership’s net income for the six-month periods ended June 30, 2019 and 2018 did not exceed the First Target Distribution Level of $1.6975 per unit per quarter, as such term is defined in the Partnership Agreement, and as a result, the assumed distribution of net income did not result in the use of increasing percentages to calculate CGP’s interest in net income.

The Two-Class Method was used to calculate EPU as follows:

Various claims, suits and complaints, including those involving government regulations and product liability, arise in the ordinary course of the shipping business. In addition, losses may arise from disputes with charterers, agents, insurance and other claims with suppliers relating to the operations of the Partnership’s vessels. The Partnership is not aware of any such claims or contingent liabilities, which should be disclosed, or for which a provision should be established in the unaudited condensed consolidated financial statements.

The Partnership accrues for the cost of environmental liabilities when management becomes aware that a liability is probable and is able to reasonably estimate the probable exposure. Currently, the Partnership is not aware of any such claims or contingent liabilities, which should be disclosed, or for which a provision should be established in the unaudited condensed consolidated financial statements.

Change of Manager: In August 2019 the Partnership completed the process of changing the manager of its vessels, from CSM to Capital-Executive Ship Management Corp. (“Capital-Executive”), a privately held company ultimately controlled by Mr. Miltiadis Marinakis. The agreement with Capital-Executive has the same terms and conditions of our floating fee management agreement with CSM. MV Cape Agamemnon will remain under the management of CSM under our floating fee management agreement with CSM. CMA CGM Amazon settlement: In September 2019, one of the Partnership’s subsidiaries reached a settlement with the U.S. Department of Justice (“DOJ”) regarding the M/V CMA CGM Amazon for oil record book violations. Under the terms of the agreement, the subsidiary pled guilty to oil record book violations with respect to the M/V CMA CGM Amazon. The subsidiary shall pay a fine of up to $500 and was placed on probation for 30 months. If, during the term of probation, the subsidiary fails to adhere to the terms of the plea agreement, the DOJ may withdraw from the plea agreement and would be free to prosecute the subsidiary on all charges arising out of its investigation, including any charges dismissed pursuant to the terms of the plea agreement, as well as potentially other charges. The subsidiary is also required to implement an environmental compliance plan in connection with the settlement.

Significant Accounting Policies [Abstract]
Changes in Accounting Policies	Changes in Accounting Policies ASU 2016-02- Leases (Topic 842): The Partnership adopted this standard for the reporting period commencing on January 1, 2019 and elected the practical expedient under ASU 2018-11 for the vessels under time charter agreements. Furthermore, the Partnership applied the transition provisions of ASU 2016-02 at its adoption date, rather than the earliest comparative period presented in the financial statements, as permitted by ASU 2018-11. The nature of the lease component and non-lease component that were combined as a result of applying the practical expedient are the contract for the hire of a vessel and the fees for operating and maintaining the vessel respectively. The lease component is the predominant component and the Partnership accounts for the combined component as an operating lease in accordance with Topic 842. The Partnership applied Topic 842 with no significant impact on its financial statements and as a result no adjustment was posted in the Partnership’s opening retained earnings as of January 1, 2019.
