Japan's NYK Line is plotting LNG tanker orders and more LNG-fuelled bulkers as it eyes new fuelling business in the west of the country.

The shipowner said it had signed a cooperation agreement with Itochu Enex, Kyushu Electric Power Co and Saibu Gas Co to commercialise the use of the gas as a marine fuel for vessels.

"The parties have decided to examine the commercialisation of an LNG bunkering business in the Setouchi and Kyushu areas of western Japan," the company said.
