GasLog Partners has fixed out one of three steam turbine LNG carriers being redelivered to the company by energy major Shell to Cheniere Energy for up to three years.

The shipowner announced it has secured a charter for its 145,000-cbm Methane Heather Sally (built 2007) with Cheniere, a US LNG producer and trader.

GasLog Partners, a spin-off of Piraeus-based LNG vessel owner GasLog, said the charter began last week and has a minimum period of one year. It added that Cheniere has the option, until late August, to extend the charter for an additional one or two years.

The New York-listed company described the Methane Heather Sally as a steam turbine vessel which previously operated in the spot market.

Reporting first-quarter results in May, GasLog Partners named the ship as one of three steam turbine vessels being handed back to the company by Shell on the expiry of their multi-year charters.

The company cited the redeliveries as one of the reasons for its drop in revenue.

GasLog Partners said it is looking at how to either modify or operate its steam ships at slow speeds to counter the effects of the International Maritime Organization's Energy Efficiency Existing Ship Index and the Carbon Intensity Indicator to cut greenhouse gas emissions.

Steam turbine vessels rank among the older ships in the world LNG fleet and have higher CO2 emissions.

Cheniere and GasLog Partners have worked together on a study to measure the methane emissions from the 174,000-cbm newbuilding GasLog Galveston.

Separately Cheniere is gearing up to issue carbon emissions tags (CE tags) to each LNG cargo it ships in a bid to provide more transparency on emissions.

Speaking about the Cheniere fixture, GasLog Partners chief executive Paul Wogan said it "deepens" the company's relationship with Cheniere.

The CEO added: "The execution of this charter on attractive terms further improves our revenue and cash flow visibility and bolsters our deleveraging strategy for 2021."

Wogan flagged up that this is the third multi-month charter signed by the partnership in recent weeks.

On 15 June, GasLog Partners announced that it had fixed two tri-fuel diesel-electric LNG carriers to TotalEnergies and secured an extension on a second ship with an energy major.
