Dynagas LNG Partners LP Enters Into New Long-Term Time Charter for the LNG Carrier Arctic Aurora and Extends Current Time Charter for the LNG Carrier Clean Energy

Contracted backlog increases to 1.51 billion with average remaining contract duration of about 10.6 years

Monaco – December 21, 2017 –Dynagas LNG Partners LP. (the "Partnership") (NYSE: "DLNG"), an owner and operator of LNG carriers, today announced the following:

The Partnership has entered into a new three year charter agreement with Statoil ASA ("Statoil") for the employment of the Arctic Aurora, its 2013-built, 155,000 cubic meter , tri-fuel diesel engine, ice class LNG carrier (the "Extended Charter"). The Arctic Aurora is currently, and has been since 2013, on charter to Statoil (the "Current Charter"). The Extended Charter is expected to commence in the third quarter of 2018 in direct continuation of the Current Charter (interrupted only by the vessel's mandatory statutory class five-year special survey and dry-docking) and will have a firm period of about 3 years +/- 30 days. Statoil will have the option to extend the Extended Charter by two consecutive 12-month periods at escalated rates.

PetroChina International (Singapore) Pte. Ltd. ("PetroChina") has exercised its right to extend the current charter term for the Clean Energy, the Partnership's 2007-built, approximately 150,000 cubic meter LNG carrier, by a minimum period of approximately 4 months. The Clean Energy was delivered to PetroChina in October 2017 and is now expected to be redelivered to the Partnership under the charter, as extended, at the earliest, in May 2018 and at latest, in June 2018, prior to its delivery to Gazprom Marketing & Trading Singapore Pte Ltd in July 2018, when the vessel will commence a time charter with a term of approximately eight years.

The extension of these two charter periods increases the Partnership's estimated contracted backlog to approximately $1.51 billion with average remaining contract duration of about 10.6 years.

Tony Lauritzen, Chief Executive Officer of the Partnership, commented:

"We are pleased to report our extended charters with Statoil and PetroChina. Statoil is an important partner for Dynagas that further solidifies our operation of LNG carriers in subzero and ice bound areas. The charter with PetroChina strengthens an important cooperation that provides cleaner energy in a rapidly growing Chinese gas market. As previously communicated we have been executing on our strategy of securing term employment for part of our availability in 2018 on the back of an improving LNG shipping market."

Forward-Looking Statements

Matters discussed in this press release may constitute forward-looking statements. The Private Securities Litigation Reform Act of 1995 provides safe harbor protections for forward-looking statements in order to encourage companies to provide prospective information about their business. Forward-looking statements include statements concerning plans, objectives, goals, strategies, future events or performance, and underlying assumptions and other statements, which are other than statements of historical facts.

The Partnership desires to take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and is including this cautionary statement in connection with this safe harbor legislation. The words "believe," "anticipate," "intends," "estimate," "forecast," "project," "plan," "potential," "may," "should," "expect," "expected," "pending" and similar expressions identify forward-looking statements.

The forward-looking statements in this press release are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, examination by the Partnership's management of historical operating trends, data contained in its records and other data available from third parties. Although the Partnership believes that these assumptions were reasonable when made, because these assumptions are inherently subject to significant uncertainties and contingencies which are difficult or impossible to predict and are beyond the Partnership's control, the Partnership cannot assure you that it will achieve or accomplish these expectations, beliefs or projections.

In addition to these important factors, other important factors that, in the Partnership's view, could cause actual results to differ materially from those discussed in the forward-looking statements include the strength of world economies and currencies, general market conditions, including fluctuations in charter rates and vessel values, changes in demand for Liquefied Natural Gas (LNG) shipping capacity, changes in the Partnership's operating expenses, including bunker prices, drydocking and insurance costs, the market for the Partnership's vessels, availability of financing and refinancing, changes in governmental rules and regulations or actions taken by regulatory authorities, potential liability from pending or future litigation, general domestic and international political conditions, potential disruption of shipping routes due to accidents or political events, vessel breakdowns and instances of off-hires and other factors. Please see our filings with the Securities and Exchange Commission for a more complete discussion of these and other risks and uncertainties.
