SHI Developed Its Own Boil-off Gas Recovery System for LNG carriers

  • Samsung Heavy Industries announced on 20 December it successfully demonstrated its own BReS, Boil-off gas Recovery System, and received Statement of Fact from ABS.
  • BReS is a system that recovers boil-off gas that is naturally evaporated in the fuel tank of LNG carriers which are increasing in orders due to strict environmental regulations, and it's a new technology that can reduce fuel consumption and carbon dioxide emissions from LNG carriers.
  • Existing systems require lots of time and cost because high-pressure compressors to convert boil-off gas into fuel are exclusively supplied by foreign manufacturers and the systems also emit carbon dioxide in the process of combusting the gas.
  • BReS is a heat exchange technology that uses cold heat from LNG which is supplied through an engine instead of a high-pressure compressor, and it can reduce investment costs by liquefying boil-off gas, and realize zero carbon emissions by re-liquefying excessive boil-off gas.
  • It is analyzed that when BReS is installed on European-Asia shipping container ships, it reduces about 30 tons of LNG fuel and 60 tons of carbon dioxide emissions per ship. 60 tons of carbon dioxide is equivalent to the amount of emissions generated when 500 cars travel between Seoul and Busan.
  • "We need to develop new technologies for carbon neutrality in the shipbuilding and shipping industry due to strengthening IMO environmental regulations", said Gun Il Park from Eco-friendly Research Center at SHI and emphasized that "SHI will continue to lead the market through the development of various eco-friendly technologies and products as well as LNG".
  • SHI has completed 15 demonstrations so far, including BReS, using LNG pilot test facilities completed in May 2021.
