••••••••••••••••••••••••••••••I••••••••••••••n^PfflHSHHHIBHHHHIH^in Great Ships of 1999 (1,560 kW), while forced boil-off, and the handling of gas fed to the main propulsion boilers, is served by two ATLAS

COPCO compressors (8,500 cu. m. /h), a forc- ing vaporizer (7,000 kg/h) and a combined heater (540 kW). Inert- ing of the insulated space and cargo tanks is by means of two Permea nitrogen generators (90 m3/h) and a MOSS inert gas generator (14,000 cu. m. /h). A particular fea- ture of design is the adoption of a single con- trol room for engine room and cargo spaces.

The high degree of automation fitted includes an operating control conditions, optimization of ship and machinery control conditions, ship management and vibration monitoring. A distributed control sys- tem incorporates four twin and three single workstations, with elec- tronically self-contained screens capable of controlling any ship func- tion, provided the operator presents the correct badge. Also included are 30 main and 70 submimic boards. New insulation material such as reinforced polyurethane foam and triplex are applied, having excellent quality and reliability, and fabricated by well-established

Korean subcontractors. Gas trials have been successfully fulfilled in

Korean LNG terminal (Incheon) this past November. Samsung began to invest and develop LNG technology in 1986, and acquired the tech- nologies of engineering and construction from GTT in 1990.

Designed and constructed to comply with the requirements of Korea Register of Shipping (KR), SK Summit, a 135,000 cu. m LNG Carrier was delivered in August 1999 to SK Ship- ping by DHI Okpo Shipyard. Registered under the Panaman- ian flag, Summit will transport Liquefied Natural Gas from

Qatar to Korea. The vessel has a continuous upper deck with aft sunken deck, as well as a raked stem with bulbous bow and bow thruster. A fixed pitch propeller is driven by a marine steam turbine. Four cargo tanks, which are capable of holding a capacity of 138,000 cu. m. capacity are designed as GTT membrane type and will keep the LNG at a temperature of - 163 degrees C under the condition of maximum daily boil-off rates less than .15 percent of fully loaded cargo volume. Via the cargo hold length, underdeck passageways are situated port and starboard in trunk deck space and also center passageway (pipe duct) with trolley system is arranged in the double bottom. A six-tier deckhouse located aft offers accommodation for 48 with vibration levels in living areas designed especially low at normal operating condition.

The vessel holds a typical cargo handling system, which has been upgraded on membrane type of LNG carriers. Liquefied cargo handling equipments such as a double set of main cargo pumps, one set of spray/stripping pump, and one set of capacitance type level gauge is present.

Summit is constructed to comply with ship/shore compatibility of the LNG loading terminal in

Qatar, Oman (Qalhat); Indonesia (Arun/Bontang); and Malaysia (Bintulu) - as well as discharge terminals in Korea.

Mooring arrangement, fender contract flat area, gangway landing position/support, manifold arrangement and ship/shore com- munication systems for these LNG termi- nals are considered sufficiently in this ves- sel.

The main powering unit is comprised of the Kawasaki cross compound steam tur- bine with high and low pressure turbine, double reduction gear and main condenser including astern turbine. The main con- denser is designed to be cooled by a scoop cooling sea water system at normal sea going condition and by main sea water circ.

Pump at the low load under 65 rpm of main turbine.

Consisting of three switchboards (main, cargo and emergency) the electric distribu- tion system is located in separate rooms.

Power is supplied to the main switchboard by three (two steam turbine-driven, one diesel engine-driven) 3,450 kW generators at 440VAC, 3-phase, 60Hz. A diesel-driven emergency generator of 850 kW capacity is connected to the emergency switchboard to meet statutory requirements and to provide for restricted operations if the main genera- tors are unavailable.

Service speed of the SK Summit is con- firmed at 20.8 knots fully loaded at 100 per- cent MCR with 21 percent sea margin, by sea trial, which is increased by .3 knots than the contracted speed of 20.5 knots.
