Japan’s NYK Line will deploy two newbuild, 174,000-m3 capacity LNG carriers for Total under a long-term contract that cements the companies’ fleet-management relationship, NYK has announced.
Scheduled for delivery by builders Samsung Heavy Industries in 2021, the vessels will be propelled by WinGD-manufactured, dual-fuel slow-speed diesel engines that, NYK Line claims, “have superior fuel-consumption efficiency and can operate on marine gas oil or boil-off gas stored in the cargo tank”.
The carriers will also feature a reliquefaction system that can tap surplus boil-off gas. Manufactured by GTT, the membrane-type tank will be made of advanced insulating materials that reduce the vaporisation rate.
The latest contract follows another long-term charter agreement with Total for a 293-m long newbuild LNG tanker, also with a capacity of 174,000 m3, that will be delivered in 2021. Agreed in late September, the contract provides for a 7-year charter with an option to extend for another year.
Meantime NYK and Total have combined to offer ship-management services through a joint venture known as Gazocean that will, the Japanese company says, “continue to deepen collaboration with Total in both LNG transportation and ship management.”
The Japanese line has been developing a next-generation LNG carrier known as Sayaringo STaGE in a joint venture with Mitsubishi known as Diamond LNG Shipping. The first vessel, Diamond Gas Orchid was delivered in July and is claimed to have superior LNG-carrying capacity and a more efficient hull design. The vessel, which will transport LNG for the Cameron LNG project in Louisiana, features a continuous steel cover that reduces weight and air resistance, the partners claim.
The STaGE technology – an acronym derived from steam turbine and gas engines – is a hybrid propulsion solution that combines a steam turbine and gas-fired engines.
