The two oil tankers are the first LNG-fueled ships SHI built at its yard. The order was granted at the end of 2015, and they were delivered this January and February, respectively.
One of the main features of the two LNG-fueled oil tankers is that compared with conventional vessels using diesel oil as fuel, they have a LNG supply system, 'S-Fugas', developed on SHI’s own that can eliminate Sox emissions by 99%, NOx emissions by 85% and CO2 emissions by 25%.
The S-Fugas is a technology necessary to be applied to the engineering and construction stage because of its feature that vaporizes LNG at the temperature of -163 degrees to supply the gas to the main engines and generators.
In addition, the ship has the INTELLIMAN ship software, which helps increase operational safety of the ships with its real-time monitoring function that shows changes in temperature and pressure, and fuel level among others, in a LNG fuel tank on board but ashore.
SHI’s own LNG propulsion technology has helped the company secure orders for 10 LNG-fueled ships from international shipowners to date this year.
What is more, ahead of the 2020 sulphur cap, SHI has made several attempts to ensure the quality of LNG-fueled vessels by applying different shapes and materials to a LNG fuel tank system and different engines.
