New York-listed GasLog Partners is buying another LNG carrier from its parent GasLog.
The company said it will acquire the 155,000-cbm tri-fuel diesel-electric unit Solaris (built 2014) for $185.9m.
The deal is expected to be financed with cash and the assumption of $117m of Solaris' existing debt.
The ship has a charter in place with Shell to 2021, with two charterers' options to extend for either five or 10 years.
