Samsung Heavy Industries

SK Supreme

LNG Carrier

SK Shipping Co.

Samsung Heavy Indus- tries Co. is scheduled to deliver by year's end, the largest size LNG carrier of

GTT Mark-Ill membrane type and is scheduled to deliver two more vessels within 2000.

Supreme, a 138,000 cu. m. LNG Carrier has been designed and constructed with the regulation of ABS and KR classification soci- eties and the membrane cargo containment system developed by GTT (Gaz Transport &

Technigaz) in France.

The cargo tanks are protected by a complete double side/bottom, cofferdam between each tanks and trunk at topside. For the hull and cargo containment system of cargo tank, Dynamic Load Analysis and extended fatigue analysis have been carried out to ensure the vessel's high reliability and long lifetime.

Cargo will be carried at -163 degrees C in the near atmospheric pressure with an insulation of 250 mm and membrane of 1.2 mm thick corrugated stainless steel sheet.

The GazTransport & Technigaz Mark-Ill system offers a low boil-off rate, in this case 0.15 percent/day of total cargo volume.

Each cargo tank is fitted with two 1,700 cu. m. /h submerged cen- trifugal pumps, which are capable of unloading cargo within 12 hours. Cargo loading is carried out by shore-based pumps, after the tanks have been pre-cooled by LNG spray. Vapor produced during this process is returned ashore through the ship's high-duty com- pressors. Boil-off gas generated on voyage is heated and delivered as fuel gas to the main boiler by a low-duty compressor and boil- off gas heater.

An elevated walkway over the tanks affords access from the Cen- tralized Administration and Control Center (CACC), located at the fourth tier level of accommodation deckhouse the wheelhouse, to the compressor room and deck. The CACC provides a central com- mand station for cargo and ballasting operations, as well as moni- toring, remote control of the propulsion plant, integrated automa- tion and shipboard management systems.

The propulsion machinery comprises a 39,500 SHP Kawasaki steam turbine set driving a fixed propeller through a double reduc- tion gearbox. The vessel's service speed stands at 20.8 knots with a 21 percent sea margin. Steam is generated by two Kawasaki boil- ers, capable of burning fuel oil, boil-off gas or a combination of both. Electrical power is derived from two turbo-alternators, each producing 3,450 kW, and a 'stand-by' 3,450 kW diesel-driven set.

Fire safety measures include dry powder and water spray for the cargo tank areas, and a water spray for the deckhouse front. Accom- modation is provided for 48 persons.

Mooring arrangement and hull parallel body have been especial- ly designed to suit the cargo loading/unloading at worldwide LNG terminals. Cargo cooling, also loading and unloading operations will be done, utilizing two Atlas Copco high duty compressors (32,000 cu. m. /h), a main vaporizer (21,300kg/h) and two heaters
