HD Hyundai Global Service Signs Contract with CoolCo for LNG Boil-off Reliquefaction Unit Retrofit

HD Hyundai Global Service, a ship service subsidiary of HD Hyundai Group, has announced that it has signed contracts on June 6th with Cool Company Ltd (NYSE: CLCO / CLCO.OL “CoolCo”), an owner and operator of LNG vessels, to retrofit five LNG carriers with sub-coolers for LNG boil-off reliquefaction (“reliquefaction units”). The contract value is approximately 10M US Dollars per vessel.

A reliquefaction unit is a device used to re-liquefy the boiled off gas (BOG) generated during the operation of LNG cargo tanks, either returning the gas to the cargo tank or preventing natural evaporation using sub-cooled LNG. When a vessel is in operation, boiled off gas (“BOG") is consumed as fuel by the propulsion engine. However, without a reliquefaction unit, during periods of reduced vessel speed, during port stays, or while utilizing the vessel for floating storage, the BOG needs to be forcibly burned, resulting in the loss of LNG cargo and the emission of greenhouse gases, leading to environmental pollution.

The utilization of a reliquefaction unit is known to be effective mainly in LNG carriers equipped with tri-fuel electric propulsion (TFDE) or two-stroke dual-fuel (DF) engines, and HD Hyundai Global Service is currently receiving inquiries from its customers for additional reliquefaction unit retrofit work similar to that being performed for CoolCo.

At the International Maritime Organization’s (“IMO”) 78th Marine Environment Protection Committee meeting in 2022, a correction item was adopted so that LNG carriers could deduct fuel consumption equivalent to the amount of power used in cargo reliquefaction equipment when calculating the ship’s Carbon Intensity Indicator (“CII”), which has been adopted as IMO’s short-term greenhouse gas measure and has been incorporated into certain international environmental regulations that tighten over time.

As a leading provider in ship services industries, HD Hyundai Global Service has a long history of providing innovative solutions to meet the needs of its customers. The retrofit of the reliquefaction unit is a testament to the company’s commitment to providing its customers with the best possible service.

CoolCo is a growth-oriented owner, operator and manager of fuel-efficient liquefied natural gas (“LNG”) carriers. Using its integrated, in-house vessel management platform, CoolCo provides charterers and third-party LNG vessel owners with modern and flexible management and transportation solutions, delivering a lesser-emitting form of energy that supports decarbonization efforts, economic growth, energy security, and improvements in quality of life. CoolCo intends to leverage its industry relationships to make further accretive acquisitions of in-service LNGCs, and to selectively pursue newbuild opportunities. The retrofit of the sub-cooling units is an important step towards achieving CoolCo’s ESG goals.

HD Hyundai Global Service plans to incorporate reliquefaction units supplied by Air Liquide, a French company specializing in this technology, and will be responsible for the overall design, product supply, installation and commissioning.

Mr. Ki-dong Lee, CEO of HD Hyundai Global Service, said, “We will contribute to the optimized response to global warming in the energy transportation sector through various ship energy-saving device retrofits, including the retrofit of the reliquefaction unit.”

Mr. Richard Tyrrell, CEO of CoolCo, added, “We are pleased to work with Hyundai Global Service on this important initiative, which is a central component in our LNGe conversion process. These reliquefaction units will provide our charterers with valuable flexibility when it comes to managing the seasonal fluctuations in LNG demand, in particular by supporting efficient travel at lower speeds, idling and floating storage applications. In addition, these retrofits will enhance the long-term value and competitiveness and reduce the environmental footprint of what will become our LNGe vessels.”
