NYK has signed long-term charter contracts for four new liquefied natural gas (LNG) carriers with EnBW Energie Baden-Württemberg AG (hereafter EnBW), a major German energy company.
Environmental Friendly
These four vessels will be built at HD Hyundai Heavy Industries Co. Ltd. in South Korea and will be completed in sequence during 2027. The 174,000 cubic meter capacity membrane-type tanks will be made of advanced insulating materials that reduce the vaporization rate. They will be propelled by fuel efficient dual-fuel slow-speed two-stroke marine engines. They will also feature a shaft generator and air lubrication system (ALS), making the ships more environmentally-friendly than conventional LNG carriers.
Outline Of Vessels
Length overall: about 289.9 meters. Breadth: about 46.1 meters. Main engine: Dual-fuel low-speed two-stroke marine engine. Cargo tank capacity: about 174,000 cubic meters. Shipbuilder: HD Hyundai Heavy Industries Co. Ltd. (South Korea). Delivery year: 2027
- Membrane type: The inside of the tank is covered with a nickel-steel or a stainless-steel membrane to maintain low temperatures and absorb gas expansion.
- Dual-fuel low-speed two-stroke marine engine: Fuel oil and boil-off gas (LNG vaporized in cargo tanks during navigation) can be used.
- Shaft generator: A device in which a generator is attached to a rotating propeller shaft to supply electricity.
- Air lubrication system (ALS): Technology that uses air bubbles to reduce the resistance between the ship’s hull and seawater.
