ClassNK approves Shin Kurushima’s LNG-fueled chemical tanker design

Japan’s classification society ClassNK granted an approval in principle (AiP) to Shin Kurushima Dockyard for its concept design of 49,000 DWT LNG-fueled chemical tanker.

The AiP was granted to the concept design based on ClassNK’s rule part GF (regulation for ships using low-flashpoint fuels) incorporating the International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code), IMO Res. MSC.391(95) and MSC.458(101).

The ship has two independent Type C LNG fuel tanks installed on its deck that do not require a secondary barrier and that minimize the impact of LNG fuel on cargo tank volume.

Its design enables the ship to run for approximately 40 days with the use of LNG fuel, thereby realizing a longer navigational cruising range.

The LNG fuel tank and gas piping from the gas bunker station to the engine room have been optimized by positioning the fuel control room between the engine room below the upper deck and the cargo tank, enabling the smooth supply of LNG fuel to the main engine, main power generator, and auxiliary boiler, ClassNK said.
