GasLog Partners LP

We are a growth-oriented limited partnership formed to own, operate and acquire 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 will have charter terms expiring in 2018 and 2019, will be contributed to us by GasLog, which will control us through its ownership of our general partner. GasLog was founded and is effectively controlled by its chairman, Peter G. Livanos, whose family’s shipping activities commenced more than 100 years ago.

Upon the closing of this offering, we will own 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 will 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 will provide us with significant built-in growth opportunities and allow us to diversify our fleet specification potentially to include steam-powered ships. 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 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 the amount of 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. 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 111% the total carrying capacity of vessels in its fleet, which includes vessels on the water, newbuildings on order and secondhand vessels under contract to be purchased. This increase includes two LNG newbuilding orders announced in February 2013 and two LNG newbuilding orders announced in August 2013, all of which are expected to be delivered in 2016, the acquisition of one 2010 built LNG carrier announced in September 2013, three secondhand steam-powered ships that were acquired from BG Group in April 2014 and the three additional secondhand steam-powered ships that are under contract to be purchased from BG Group. Each of the four newbuildings is under a long-term charter, which will commence upon delivery. Since January 1, 2013, GasLog has taken delivery of five LNG carriers, acquired one on-the-water vessel, entered into contracts to purchase six secondhand vessels (three of which have been delivered and three of which are under contract) and secured additional LNG newbuilding options. GasLog currently has a fully-owned twenty-one-ship fleet, including fourteen ships on the water (two ships delivered in 2010, five ships delivered in 2013, one on-the-water ship acquired in 2013, three secondhand ships that were acquired from BG Group in April 2014 and three additional secondhand ships being acquired from BG Group), and seven LNG carriers on order from Samsung.

Option Vessels

We will have the option to purchase the following twelve LNG carriers from GasLog within 36 months after each such vessel’s acceptance by its charterer (or, in the case of the GasLog Seattle, the three vessels recently acquired from BG Group and the three additional vessels under contract to be purchased from BG Group, 36 months after the closing of this offering), in each case at fair market value as determined pursuant to the omnibus agreement.

As of the date of this prospectus, we have not secured any financing in connection with the twelve optional vessels. Our ability to purchase these twelve 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—Risk Inherent in Our

2

Business—We may have difficulty obtaining consents that are necessary to acquire vessels with an existing charter or financing agreement”.

GasLog also has the following six 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:

(3)				Indicates the duration of the initial term. The charterers have unilateral options to extend the term of the time charters for periods ranging from 30 to 90 months, provided that the charterer provides us with advance notice of declaration of any option in accordance with the terms of the applicable charter.
(4)				Time charter provides for full employment for three years and a subsequent five year seasonal charter under which the ship is employed for seven months and available to accept other charters for five months.

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. GasLog has also entered into a letter of intent with Samsung for the purchase of two additional 174,000 cbm newbuildings from Samsung with delivery dates in 2017. The letter of intent is subject to final GasLog board approval and execution of definitive agreements. If definitive agreements for the purchase of these two newbuild vessels are signed, Samsung has agreed to grant GasLog options with a four month option term on two further 174,000 cbm newbuildings with delivery dates in 2017 and 2018. Except as discussed elsewhere in this prospectus, this right will continue throughout the entire term of the omnibus agreement. 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 and, with respect to the initial fleet only, to indemnify us if such consents are not obtained. 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—Agreements Governing the 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 will give 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 customers. As of April 18, 2014, GasLog owned 21 LNG carriers (including the vessels in our initial fleet), which includes seven newbuildings on order, the three vessels recently acquired from BG Group and three vessels under contract to be purchased from BG Group. Since its initial public offering in April 2012, GasLog has increased by approximately 111% the total carrying capacity of vessels in its fleet, which includes vessels on the water, newbuildings on order and secondhand vessels under contract to be purchased. In addition, GasLog, through its wholly owned subsidiary GasLog LNG Services, will provide 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

4

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 57.24% limited partner interest in us, which consists of 1,422,358 common units and all of our subordinated units. As a result, GasLog will hold a majority of our total equity interests. Our general partner, by virtue of its general partner interest, will also initially control 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

Our partnership agreement provides that our general partner will delegate 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 March 31, 2015. For a more detailed description of this arrangement, see “Certain Relationships and Related Party Transactions—Agreements Governing the Transactions—Administrative Services Agreement”.

Our operating subsidiaries are party to commercial management agreements, which will be amended in connection with this offering, 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 under the amended commercial management agreements for the twelve months ending March 31, 2015. For a more detailed description of this arrangement, see “Certain Relationships and Related Party Transactions—Agreements Governing the Transactions—Commercial Management Agreements”.

In addition, our operating subsidiaries are party to ship management agreements, which will be amended in connection with this offering, with GasLog LNG Services 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 March 31, 2015. For a more detailed description of this arrangement, see “Certain Relationships and Related Party Transactions—Agreements Governing the Transactions—Ship Management Agreements”.

The Offering

16

		Within 45 days after the end of each fiscal quarter (beginning with the quarter ending June 30, 2014), we will distribute all of our available cash to unitholders of record on the applicable record date. We will adjust the minimum quarterly distribution for the period from the closing of this offering through June 30, 2014 based on the actual length of the period. Our ability to pay our minimum quarterly distribution is subject to various restrictions and other factors described in more detail under the caption “Our Cash Distribution Policy and Restrictions on Distributions”.
		If cash distributions to our unitholders exceed $0.43125 per unit in a quarter, holders of our incentive distribution rights (initially, GasLog) will receive increasing percentages, up to 48.0%, of the cash we distribute in excess of that amount. We refer to these distributions as “incentive distributions”. We must distribute all of our cash on hand at the end of each quarter, less reserves established by our board of directors to provide for the proper conduct of our business, to comply with any applicable debt instruments or to provide funds for future distributions. We refer to this cash as “available cash”, and we define its meaning in our partnership agreement. The amount of available cash may be greater than or less than the aggregate amount of the minimum quarterly distribution to be distributed on all units.
		We believe, based on the estimates contained in and the assumptions listed under “Our Cash Distribution Policy and Restrictions on Distributions—Forecasted Cash Available for Distribution”, that we will have sufficient cash available for distribution to enable us to pay the minimum quarterly distribution of $0.375 on all of our common and subordinated units for each quarter through March 31, 2015. However, unanticipated events may occur that could adversely affect the actual results we achieve during the forecast period. Consequently, our actual results of operations, cash flows and financial condition during the forecast period may vary from the forecast, and such variations may be material. Prospective investors are cautioned not to place undue reliance on the forecast and should make their own independent assessment of our future results of operations, cash flows and financial condition.
		See “Our Cash Distribution Policy and Restrictions on Distributions—Forecasted Cash Available for Distribution”.
Subordinated units		GasLog will initially own all of our subordinated units. The principal difference between our common units and subordinated units is that in any quarter during the subordination period the subordinated units are entitled to receive the minimum quarterly distribution of $0.375 per unit only after the common units have received the minimum quarterly distribution and arrearages in the payment of the minimum quarterly distribution from prior quarters. Subordinated units will not accrue arrearages. The subordination period generally will end if we have earned and

17

		paid at least $0.375 on each outstanding common and subordinated unit and the corresponding distribution on our general partner’s 2.0% interest for any three consecutive four-quarter periods ending on or after March 31, 2017. If the subordination period ends as a result of us having met the tests described above, all subordinated units will convert into common units on a one-for-one basis, and the common units will no longer be entitled to arrearages.
		For purposes of determining whether the subordination period will end, the three consecutive four-quarter periods for which the determination is being made may include one or more quarters with respect to which arrearages in the payment of the minimum quarterly distribution on the common units have accrued, provided that all such arrearages have been repaid prior to the end of each such four-quarter period.
		See “How We Make Cash Distributions—Subordination Period”.
GasLog’s right to reset the target distribution levels		GasLog, as the initial holder of all of our incentive distribution rights, has the right, at a 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%) for each of the prior four consecutive fiscal quarters, to reset the initial cash target distribution levels at higher levels based on the distribution at the time of the exercise of the reset election. If GasLog transfers all or a portion of the incentive distribution rights it holds in the future, then the holder or holders of a majority of our incentive distribution rights will be entitled to exercise this right. Following a reset election by GasLog, the minimum quarterly distribution amount will be reset to an amount equal to the average cash distribution amount per common unit for the two fiscal quarters immediately preceding the reset election (we refer to such amount as the “reset minimum quarterly distribution amount”), and the target distribution levels will be reset to correspondingly higher levels based on the same percentage increases above the reset minimum quarterly distribution amount as our current target distribution levels.
		In connection with resetting these target distribution levels, GasLog will be entitled to receive a number of common units equal to that number of common units whose aggregate quarterly cash distributions equaled the average of the distributions to it on the incentive distribution rights in the prior two quarters. The general partner will also receive additional general partner units in order to maintain its ownership interest relative to the common units. For a more detailed description of GasLog’s right to reset the target distribution levels upon which the incentive distribution payments are based, see “How We Make Cash Distributions—GasLog’s Right to Reset Incentive Distribution Levels”.
Issuance of additional units		We can issue an unlimited number of additional units, including units that are senior to the common units in rights of
