Japanese classification society ClassNK on Friday (13 March) granted  an Approval in Principle (AiP) to Shin Kurushima Dockyard Ltd for their concept design of a 49,000 dwt liquid natural gas (LNG) fueled chemical tanker. 

ClassNK said the AiP was granted to the concept design based on its Rule Part GF (regulation for ships using low-flashpoint fuels) incorporating “International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code), IMO Res. MSC.391(95) and MSC.458(101)”.

In Class NK’s official press release, it said the main features of the design announced by Shin Kurushima Dockyard are as follows:

  • 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.
