ClassNK issues AIP for Japanese-designed methanol dual-fuel tanker

ClassNK has issued an approval in principle (AIP) for the design of a methanol dual-fuel tanker developed by Sumitomo Heavy Industries Marine and Engineering Company.

ClassNK confirmed the design's compliance with the IMO's Interim Guidelines for the Safety of Ships using Methyl/Ethyl Alcohol as Fuels published in December 2020, and ClassNK's Guidelines for Ships Using Low-Flashpoint Fuels published in 2019.

Sumitomo said the tanker was designed to allow the installation of a main engine and a methanol fuel supply system including a fuel pump, a tank, and a control system. The main engine will be capable of operating on methanol as an alternative to conventional fuel oil.

The tanker will also feature double walled fuel oil piping, a leak detection system, and other equipment to ensure improved safety against leakage and fire.
