LNG Industry,

Sumitomo Heavy Industries Marine & Engineering Co., Ltd. was granted an ‘Approval in Principle’ (AiP) from Lloyd’s Register Group Limited for a medium-size tanker equipped with a high-pressure LNG dual-fuel system.

This tanker is equipped with an LNG dual-fuel system and large-capacity LNG tank. The vessel can substantially reduce the amount of sulfur oxide (SOx), nitrogen oxide (NOx), and carbon dioxide (CO2) contained in the engine exhaust gas by using LNG as primary fuel. LNG fuelled engine present environmental challenges in that unburnt methane is emitted into the atmosphere from their exhaust gas. However, the ME-GI type main engine, designed by MAN Energy & Solutions, that will be installed on the vessel will substantially reduce those emissions and also improve fuel efficiency. High-pressure LNG that has been pressurised to approximately 300 bar will be supplied to this main engine through an LNG pump and vaporiser.

As global efforts continue to be made to accelerate the reduction of GHG emissions in the international shipping industry, demand for environmental-friendly ships will be growing. Sumitomo’s state of the art tanker will far exceed the level of Phase 3 of the Energy Efficiency Design Index (EEDI), which will be mandatory to ships deployed in the international trade.

A Sumitomo company statement in relation to this recent news said:

“We are committed to doing our part in realising a sustainable shipping industry. Accordingly, we will continue meeting social demands by fully utilising our technical and developmental capabilities. And we will remain focused on supplying our customers with environment-friendly ships with a greatly reduced environmental footprint in all areas, including greenhouse gases.”
