GasLog Partners LP

We are a growth-oriented limited partnership focused on owning, operating and acquiring liquefied natural gas, or “LNG”, carriers engaged in LNG transportation under long-term charters, which we define as charters of five full years or more. Our initial fleet of three LNG carriers, which have charter terms expiring in 2018 and 2019, were contributed to us by GasLog, which controls us through its ownership of our general partner.

Our initial fleet consists of three LNG carriers, built in 2013, with modern tri-fuel diesel electric propulsion technology that operate under long-term charters with subsidiaries of BG Group. We also have options and other rights under which we may acquire additional LNG carriers from GasLog, as described below. We believe that such options and rights provide us with significant built-in growth opportunities. We may also acquire vessels from shipyards or other owners. We intend to operate our vessels under long-term charters with predictable cash flows and to grow our position in the LNG market through further acquisitions of LNG carriers from GasLog and third parties. We believe we can grow our distributions per unit organically by providing reliable customer service to our charterers and leveraging GasLog’s relationships, expertise and reputation. We intend to make further acquisitions of LNG carriers from GasLog, including the Pending Vessel Acquisition, and third parties to grow our fleet. However, we cannot assure you that we will make any particular acquisition or that as a consequence we will successfully grow our per unit distributions. Among other things, our ability to acquire additional LNG carriers will be dependent upon our ability to raise additional equity and debt financing.

GasLog is, we believe, a leading independent international owner, operator and manager of LNG carriers and provides support to international energy companies as part of their LNG logistics

chain. GasLog was founded and is effectively controlled by its chairman, Peter G. Livanos, whose family’s shipping activities commenced more than 100 years ago. On April 4, 2012, GasLog completed its initial public offering, and its common shares began trading on the New York Stock Exchange on March 30, 2012, under the symbol “GLOG”. At the time of its initial public offering, GasLog’s owned fleet consisted of ten LNG carriers, including eight newbuildings on order. Since its initial public offering, GasLog has increased by approximately 126% the total carrying capacity of vessels in its fleet, which includes vessels on the water and newbuildings on order. This increase includes: two LNG newbuilding orders announced in February 2013, two LNG newbuilding orders announced in August 2013, two LNG newbuilding orders and two exercised options for newbuilding orders announced in June 2014, all of which are expected to be delivered through the second half of 2017; the acquisition of one 2010 built LNG carrier announced in September 2013; and six secondhand steam-powered ships that were acquired from BG Group in April and June 2014. Each of the four newbuildings announced in 2013 is under a long-term charter, which will commence upon delivery. Since January 1, 2013, GasLog has taken delivery of five LNG carriers. As of August 1, 2014, GasLog has a fully owned 22 ship fleet, including 12 ships on the water and 10 LNG carriers on order from Samsung and Hyundai, as well as a 51.8% ownership in the Partnership.

Pending Vessel Acquisition

On August 14, 2014, we entered into a Share Purchase Agreement to purchase from GasLog Carriers, a direct subsidiary of GasLog, 100% of the ownership interests in GAS-sixteen Ltd. and GAS-seventeen Ltd., the entities that own the Methane Rita Andrea and the Methane Jane Elizabeth , respectively, for an aggregate purchase price of $328.0 million, which will be funded with a combination of new or existing debt (as discussed below) and proceeds raised in this offering. GasLog purchased the Methane Rita Andrea and the Methane Jane Elizabeth from BG Group in April 2014. In connection with the transaction, the Partnership will acquire GAS-sixteen Ltd. and GAS-seventeen Ltd. with $2.0 million of positive net working capital existing at the time of closing. GasLog supervised the construction of each ship and has provided technical management for the ships since delivery. We refer to this transaction as the “Pending Vessel Acquisition”.

The entities being purchased pursuant to the Pending Vessel Acquisition currently have $217.0 million of outstanding indebtedness in respect of the two vessels to be acquired. In connection with the Pending Vessel Acquisition, such indebtedness is expected to be partially prepaid with a portion of the proceeds of this offering. In addition, at or shortly following the closing of the Pending Vessel Acquisition, we expect to refinance all our outstanding indebtedness and the indebtedness of the entities being acquired pursuant to the Pending Vessel Acquisition with borrowing under the New Credit Facility   (as defined below). See “—Recent Developments”.

The following table provides information about the ships to be purchased under the Pending Vessel Acquisition:

The Pending Vessel Acquisition and the purchase price were approved by our board of directors and the conflicts committee of our board of directors, or the “conflicts committee”. The conflicts committee retained an independent financial advisor to assist it in evaluating the Pending Vessel Acquisition. In determining that the Pending Vessel Acquisition is fair and reasonable to us, the conflicts committee obtained the views of its financial advisor as to the fairness of the purchase price.

We have agreed to the Pending Vessel Acquisition for the following reasons:

We estimate that the vessels being acquired will generate $47.7 million of incremental contracted revenue over their initial charter terms and add over $34.5 million per annum to our EBITDA ⁽¹⁾ . However, we may not realize that level of revenue or EBITDA from the acquisition of these vessels.

If the Pending Vessel Acquisition is consummated, our management intends to recommend to our board of directors an increase in our quarterly cash distribution of between $0.05625 and $0.06250 (between $0.225 and $0.250 per unit on an annualized basis), which would become effective for our distribution with respect to the quarter ending   , 2014. Combined with the existing minimum quarterly cash distribution of $0.375, this proposed increase to between $0.43125 to $0.43750 per quarter would result in the quarterly distribution exceeding the first incentive distribution right threshold of $0.43125. Any such increase would be conditioned upon, among other things, the closing of the Pending Vessel Acquisition, the approval of such increase by our board of directors and the absence of any material adverse developments or potentially attractive opportunities that would make such an increase inadvisable.

			comparability is achieved by excluding the potentially disparate effects between periods of interest, gain/loss on interest rate swaps, depreciation and amortization and taxes, which items are affected by various and possibly changing financing methods, capital structure and historical cost basis and which items may significantly affect results of operations between periods. We believe that including EBITDA as an operating measure benefits investors in (a) selecting between investing in us and other investment alternatives and (b) monitoring our ongoing operational strength and cash generating ability in assessing whether to continue to hold common units.
			EBITDA has limitations as an analytical tool (see “—Summary Financial and Operating Data”) and should not be considered an alternative to profit/(loss), profit/(loss) from operations, cash flow (used in)/from operating activities or any other measure of operating performance or liquidity presented in accordance with IFRS. EBITDA excludes some, but not all, items that affect profit/(loss) and net cash from operating activities, and these measures may vary among other companies. Therefore, EBITDA may not be comparable to similarly titled measures of other companies.
			Estimated EBITDA for the two LNG carriers we are purchasing for the first twelve months of operation is based on the following assumptions:

	•		closing of the Pending Vessel Acquisition in the third quarter of 2014 and timely receipt of charter hire specified in the charter contracts;
	•		utilization of 363 days per year and no drydocking;
	•		vessel operating and supervision costs and charter commissions per current internal estimates; and
	•		general and administrative expenses based on management’s current internal estimates.

We consider the above assumptions to be reasonable as of the date of this prospectus, but if these assumptions prove to be incorrect, actual EBITDA for the vessels could differ materially from our estimates. The prospective financial information was not prepared with a view toward public disclosure or with a view toward complying with the guidelines established by the American Institute of Certified Public Accountants. Neither our independent auditors, nor any other independent accountants, have compiled, examined, or performed any procedures with respect to the prospective financial information contained above, nor have they expressed any opinion or any other form of assurance on such information or its achievability and assume no responsibility for, and disclaim any association with, such prospective financial information.

We intend to use the proceeds of this offering, and the related capital contribution to us by our general partner, to partially fund the purchase price for the Pending Vessel Acquisition and to prepay or refinance related indebtedness.

We expect the Pending Vessel Acquisition to close following the closing of this offering, subject to the Partnership obtaining the funds necessary to pay the purchase price and the satisfaction of certain other closing conditions. The Pending Vessel Acquisition may not close as anticipated or it may close with adjusted terms. See “Risk Factors—Risks Inherent in Our Business—The Pending Vessel Acquisition may not close as anticipated or it may close with adjusted terms”. This offering is not conditioned on the closing of the Pending Vessel Acquisition. If the Pending Vessel Acquisition does not close, we will use the net proceeds from this offering and the related capital contribution to us by our general partner for general partnership purposes.

The Pending Vessel Acquisition will be accounted for as a reorganization of companies under common control. Beginning with the first quarter following the completion of the Pending Vessel Acquisition, the Partnership’s historical results will be retroactively restated to reflect the historical results of the Methane Rita Andrea and Methane Jane Elizabeth during the periods they were owned by GasLog.

Recent Developments

GasLog Partners LP

On August 1, 2014, we announced a partial cash distribution for the second quarter of 2014 of $4.13 million, or $0.20604 per unit, pro-rated from the IPO closing date through June 30, 2014, payable on August 14, 2014 to all unitholders of record as of August 11, 2014. This distribution corresponds to a quarterly distribution of $0.375 per unit, or $1.50 per unit per year.

On August 5, 2014, we entered into a commitment letter and a coordination letter with Citibank for a credit facility for up to $450 million, or the “New Credit Facility”, to refinance the existing debt facilities for our initial fleet, as well as the debt facilities for the vessels to be acquired pursuant to the Pending Vessel Acquisition. The refinanced debt is expected to have a tenor of five years and an amortization profile of 20 years, which we believe will increase our financial flexibility. The New Credit Facility will be secured by a first priority mortgage on each of our existing vessels and, when delivered, the vessels to be acquired pursuant to the Pending Vessel Acquisition, a specific assignment of each of the existing charters and a first assignment of earnings and insurances in relation to the vessels. The New Credit Facility will bear interest at LIBOR plus a margin and will be payable in 20 equal quarterly payments of $5.625 million each and a balloon payment of $337.5 million together with the final quarterly payment. We expect that the New Credit Facility will have financial and restrictive covenants that are consistent with our existing debt. The closing of the New Credit Facility is subject to conditions precedent, including the negotiation and execution of final documentation and final lender approvals. We expect the New Credit Facility to be entered into and funded at or shortly following the closing of the Pending Vessel Acquisition. In addition, at the closing of the Pending Vessel Acquisition, we expect to use a portion of the proceeds from this offering to prepay amounts related to the Methane Rita Andrea and Methane Jane Elizabeth currently outstanding under the Facility Agreement between GAS-sixteen Ltd., GAS-seventeen Ltd. and GAS-eighteen Ltd. as borrowers, Citibank, N.A., London Branch, or “Citibank”, as mandated lead arranger, the financial institutions listed in Schedule 1 thereto as lenders, Citibank as bookrunner, Citibank International Plc as agent of the other finance parties and Citibank as security agent and trustee, or the “Citibank Facility”, which such borrowers entered into to finance the purchase of the Methane Rita Andrea and the Methane Jane Elizabeth (as well as the Methane Lydon Volney , which is not being acquired in the Pending Vessel Acquisition). See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources”.

If the New Credit Facility described above is not entered into and funded at or prior to the closing of the Pending Vessel Acquisition, (1) the Citibank Facility will remain in place and (2) as required by the Citibank Facility, we and GasLog Partners Holdings LLC, our wholly owned subsidiary, will enter into a guarantee agreement with Citibank pursuant to which we and GasLog Partners Holdings LLC will guarantee the obligations of the borrowers under the Citibank Facility (including GAS-eighteen Ltd., an entity that will not be acquired from GasLog under the Pending Vessel Acquisition), or the “Guarantee”. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources”. The funding of the New Credit Facility is not a condition to the completion of this offering or the Pending Vessel Acquisition.

GasLog Ltd.

In May 2014, subsidiaries of GasLog entered into shipbuilding contracts with Samsung for the construction of two LNG carriers (174,000 cbm each). The vessels are expected to be delivered in the first and second half of 2017, respectively.

In June 2014, subsidiaries of GasLog entered into shipbuilding contracts with Hyundai for the construction of two LNG carriers (174,000 cbm each). The vessels are expected to be delivered in the second half of 2017.

5

On June 30, 2014, GasLog took delivery of the Solaris , a 155,000 cbm LNG carrier constructed by Samsung that commenced her seven year charter party agreement with Shell.

Option Vessels

We have the option to purchase the following 12 LNG carriers from GasLog, including the two vessels to be acquired pursuant to the Pending Vessel Acquisition, within 36 months after each such vessel’s acceptance by its charterer (or, in the case of the GasLog Seattle and the six vessels recently acquired from BG Group, including the two vessels subject to the Pending Vessel Acquisition, 36 months after the closing of the IPO), in each case at fair market value as determined pursuant to the omnibus agreement.

Our ability to purchase these optional vessels, should we exercise our right to purchase such vessels, is dependent on our ability to obtain financing to fund all or a portion of the acquisition costs of these vessels and may be dependent on the consent of existing lenders to GasLog with respect to these optional vessels. See “Risk Factors—Risks Inherent in Our Business—We may have difficulty obtaining consents that are necessary to acquire vessels with an existing charter or financing agreement”. As of the date of this prospectus, we have not secured any financing in connection with the 12 optional vessels (other than those to be acquired pursuant to the Pending Vessel Acquisition). In connection with the Pending Vessel Acquisition, we will enter into the New Credit Facility or the Guarantee. See “—Recent Developments”.

GasLog also has the following 10 additional carriers in its fleet, which it will be required to offer to us for purchase at fair market value as determined pursuant to the omnibus agreement if charters are secured with committed terms of five full years or more:

6

In addition to the LNG carriers described in the preceding paragraphs, we intend to leverage our relationship with GasLog to make accretive acquisitions of LNG carriers with long-term charters from GasLog and third parties to increase our distributions per unit. Pursuant to the omnibus agreement, GasLog will be required to offer to us for purchase any other LNG carriers with cargo capacities greater than 75,000 cbm engaged in oceangoing LNG transportation that GasLog owns or acquires if charters are secured with committed terms of five full years or more. Except as discussed elsewhere in this prospectus, this right will continue throughout the entire term of the omnibus agreement. In addition to GasLog’s committed order book, GasLog currently holds fixed price options from Samsung on two additional 174,000 cbm newbuildings with delivery dates in 2017 and early 2018. If GasLog exercises these options, Samsung has agreed to grant GasLog two additional options. GasLog also holds fixed price options from Hyundai on four additional 174,000 cbm newbuildings with delivery dates in late 2017 and during 2018. In addition, we will have a right of first offer with regard to any proposed sale, transfer or other disposition of any LNG carriers with cargo capacities greater than 75,000 cbm engaged in oceangoing LNG transportation under a charter of five full years or more that GasLog owns, as discussed elsewhere in this prospectus. Our ability to acquire additional LNG carriers from GasLog is subject to obtaining any applicable consents of governmental authorities and other non-affiliated third parties, including the relevant lenders and charterers. Under the omnibus agreement, GasLog will be obligated to use reasonable efforts to obtain any such consents. Our ability to exercise any right to acquire additional LNG carriers will also be subject to our ability to obtain additional equity and debt financing. We cannot assure you that in any particular case the necessary consent will be obtained. See “Certain Relationships and Related Party Transactions—Omnibus Agreement”.

Our Relationship with GasLog Ltd.

We believe that one of our principal strengths is our relationship with GasLog. We believe our relationship with GasLog gives us access to GasLog’s relationships with leading energy companies, shipbuilders, financing sources and suppliers and to its technical, commercial and managerial expertise, which we believe will allow us to compete more effectively when seeking additional

7

customers. As of August 1, 2014, GasLog has a fully owned 22 ship fleet, including 12 ships on the water and 10 LNG carriers on order from Samsung and Hyundai, as well as a 51.8% ownership in the Partnership. Since its initial public offering in April 2012, GasLog has increased by approximately 126% the total carrying capacity of vessels in its fleet, which includes vessels on the water and newbuildings on order. In addition, GasLog, through its wholly owned subsidiary GasLog LNG Services, provides ship management services to the LNG carriers in our initial fleet and, subject to any alternative arrangements with the applicable charterer, additional ships we may acquire from GasLog. GasLog will also provide certain administrative and commercial management services to the Partnership.

GasLog was incorporated in 2003 and is effectively controlled by its chairman, Peter G. Livanos, who beneficially owns approximately 39.0% of GasLog’s common shares. Mr. Livanos’ family’s shipping activities commenced more than 100 years ago. On April 4, 2012, GasLog completed its initial public offering and its common shares began trading on the New York Stock Exchange on March 30, 2012, under the symbol “GLOG”. GasLog completed a $199 million follow-on public offering and concurrent private placement on January 22, 2014, to fund a portion of the cost of the acquisition of the three vessels recently purchased from BG Group, and on April 16, 2014, GasLog completed a $110 million follow-on public offering to fund a portion of the cost of the acquisition of the three vessels under contract to be purchased from BG Group.

Upon completion of this offering, GasLog will own our 2.0% general partner interest, all of our incentive distribution rights and a   % limited partner interest in us, which consists of 162,358 common units and all of our subordinated units. Our general partner, by virtue of its general partner interest, controls the appointment of three of our five directors (subject to its right to transfer the power to elect one director to the common unitholders so that they will thereafter elect a majority of our directors). GasLog intends to utilize us as its primary growth vehicle to pursue the acquisition of LNG carriers that are expected to generate long-term, stable cash flows.

Our Management

In accordance with our partnership agreement, our general partner has delegated to our board of directors the authority to oversee and direct our operations, management and policies on an exclusive basis. Certain of our directors and officers also currently serve as directors and officers of GasLog or its affiliates. For more information about these individuals, see “Management—Directors and Executive Officers”.

Pursuant to the administrative services agreement, we will pay a fixed fee to GasLog for the reasonable costs and expenses incurred in connection with providing administrative services to us. For the three vessels in our initial fleet, we expect that we will pay approximately $1.8 million under the administrative services agreement for the twelve months ending September 30, 2015. For the vessels to be acquired pursuant to the Pending Vessel Acquisition, we expect that we will pay approximately $1.2 million under the administrative services agreement for the twelve months ending September 30, 2015. For a more detailed description of this arrangement, see “Certain Relationships and Related Party Transactions—Administrative Services Agreement”.

Our operating subsidiaries are party to commercial management agreements, which were amended in connection with the IPO, pursuant to which we will reimburse GasLog for the reasonable costs and expenses incurred in connection with providing commercial management services to us. For the three vessels in our initial fleet, we expect that we will pay approximately $1.1 million in total under the amended commercial management agreements for the twelve months ending September 30, 2015. For a more detailed description of this arrangement, see “Certain Relationships and Related Party Transactions—Commercial Management Agreements”. The entities being acquired in connection with the Pending Vessel Acquisition are also party to similar commercial management agreements which are being amended in connection with this offering, and we expect that we will pay GasLog approximately $0.7 million in total under the amended commercial management agreements for the twelve months ending September 30, 2015.

In addition, our operating subsidiaries are party to ship management agreements with GasLog LNG Services, which were amended in connection with the IPO, that govern the crew and technical management of the vessels in our fleet. For the three vessels in our initial fleet, we expect that our operating subsidiaries will pay GasLog LNG Services approximately $1.7 million in total under the amended ship management agreements for the twelve months ending September 30, 2015. For a more detailed description of this arrangement, see “Certain Relationships and Related Party Transactions—Ship Management Agreements”. The entities being acquired in connection with the Pending Vessel Acquisition are also party to similar ship management agreements which are being amended in connection with this offering, and we expect that our operating subsidiaries will pay GasLog LNG Services approximately $1.1 million in total under the amended ship management agreements for the twelve months ending September 30, 2015.
