Sumitomo Heavy Industries Receives AiP For Medium-Size High-Pressure LNG Dual-Fueled Tanker

On July 9, 2020, 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 a 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 a primary fuel. LNG fueled engine presents environmental challenges in that unburnt methane (a greenhouse gas) 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 pressurized to approximately 300 bar will be supplied to this main engine through an LNG pump and vaporizer.

As global efforts are made to accelerate the reduction of greenhouse gas emissions in international shipping, the 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.

We are committed to doing our part in realizing a sustainable shipping industry. Accordingly, we will continue meeting social demands by fully utilizing 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.
