A reliquefaction unit is a tool used to re-liquefy the boiled off fuel (BOG) generated through the operation of LNG cargo tanks, both returning the fuel to the cargo tank or stopping pure evaporation utilizing sub-cooled LNG. When a vessel is in operation, BOG is consumed as gasoline by the propulsion engine. Nonetheless, with no reliquefaction unit, during times of lowered vessel velocity, throughout port stays, or whereas utilising the vessel for floating storage, the BOG must be forcibly burned, ensuing within the lack of LNG cargo and the emission of greenhouse gases, resulting in environmental air pollution.

The utilisation of a reliquefaction unit is understood to be efficient primarily in LNG carriers outfitted with tri-fuel electrical propulsion (TFDE) or two-stroke dual-fuel (DF) engines, and HD Hyundai World Service is presently receiving inquiries from its clients for extra reliquefaction unit retrofit work much like that being carried out for CoolCo.

On the Worldwide Maritime Group’s (IMO) 78th Marine Surroundings Safety Committee assembly in 2022, a correction merchandise was adopted in order that LNG carriers might deduct gasoline consumption equal to the quantity of energy utilized in cargo reliquefaction tools when calculating the ship’s Carbon Depth Indicator (CII), which has been adopted as IMO’s short-term greenhouse fuel measure and has been included into sure worldwide environmental rules that tighten over time.

As a number one supplier in ship providers industries, HD Hyundai World Service has a protracted historical past of offering revolutionary options to satisfy the wants of its clients.
