Construction of “K” Line next-generation LNG fuelled car carrier reaches milestone

26 May 2020

Japanese shipping company Kawasaki Kisen Kaisha, Ltd. (“K” Line) on Wednesday (20 May) said liquified natural gas (LNG) fuel tanks have been installed on its newbuild car carrier which is under construction at Tadotsu Shipyard Co.,Ltd. (Imabari Shipbuilding Group). 

The construction is currently on-going with estimated delivery to be within the 2020 fiscal year.

It shared the vessel is equipped with a Dual-Fuel Diesel Engine (Mitsui MAN B&W ME-GI), and a Fuel Gas Supply System (FGSS) engineered by TGE Marine Gas Engineering GmbH of Mitsui E&S Group.

The FGSS is composed of a LNG fuel tank and high-pressure pump. The LNG fuel tank on the vessel is an independent type C tank, which allows the design pressure to be set higher than other types of LNG fuel tanks. 

As the boiling point of methane (the main component of LNG) is -161.5℃, LNG is constantly being vaporised due to heat input from the tank’s external environment.

Therefore, the tank’s pressure is increased by the vaporised gas inside of the tank. The type C independent tank allows vaporised gas to be kept in the tank for a relatively longer period of time.
