New York-listed GasLog says the energy firm has fixed three newbuildings on long-term charters and has the option to take six more.

Contracts for the firm vessels involve one ship at Samsung Heavy Industries and two at Hyundai Heavy Industries, a statement says.

Deals worth $845m will begin in 2018 and early 2019 and run for 9.5 years at what GasLog calls attractive rates.
