According to a statement by Korean Register (KR) on Wednesday, the demonstration took place at HD Hyundai Heavy’s Ulsan yard.
The joint technology development project, launched in March of this year, was initiated by HD Hyundai Heavy and its parent HD KSOE, while other partners include KR, DongHwa Pneutec, and the Liberian Registry.
KR claims this is the world’s first demonstration of technology to recycle BOG from LNG-fueled propulsion ships under construction into city gas.
Since March, HD Hyundai Heavy and DongHwa Pneutec have been collaborating to develop a BOG treatment facility, while KR and the Liberian Registry have been verifying the entire process, from design to operation.
BOG is generated naturally as LNG stored in a ship’s fuel tank vaporizes, increasing internal tank pressure.
While the vessel is in operation, this gas is fully utilized as propulsion fuel, but when the ship is berthed, BOG must be combusted using boilers or generators.
During the shipbuilding phase, combustion capacity is limited, necessitating the unavoidable release of BOG into the atmosphere to manage tank pressure.
Once the development of this technology is completed, it is expected to lay the foundation for recycling evaporated gas, which generates more than 50 tons per vessel when building LNG-powered ships, into onshore city gas, as well as effectively respond to port environmental regulations, according to KR.
KR did not reveal the name of the LNG dual-fuel container vessel.
Based on the image above it is an MSC ship.
MSC previously ordered six LNG dual-fuel containerships with a capacity of 7,900 teu at the shipbuilder.
