Golar Viking, A 140,000 cu. m. Membrane LNG Carrier

Hyundai Heavy Industries Co.. Ltd. (HHI) will deliv- er a 140,000 cu. m. LNG carrier to Golar LNG of

Norway in December 2004. Golar Viking is 918 x 141 x 85 ft. (280 x 43 x 36 m) with a designed draft of 37.4 ft. (11.4 m). Equipped with four Mark membrane cargo tanks, the ship is of flush decker without forecastle and has a lowered mooring deck, transom stern and single screw propeller driven by a steam turbine. Golar

Viking has a flat deck configuration. It gives easy access from the Central Control Room (C.C.R) situat- ed just below wheelhouse, to the compressor room and to the trunk deck for easy survey, inspection & mainte- nance of the cargo piping and the electric cable. A shore manifold is provided on each side of the upper deck between Nos. 2 and 3 tanks. A compressor room is arranged on the starboard side on the upper deck above four tanks. Tank insulation is of GTT Mark sys- tem which has a 270 mm thick to satisfy the low boil off rate of 0.15 °/c by volume of the total cargo per day.

Cargo loading of the ship is performed by shore pump facilities after cargo tank is cooled down reach to the proper temperature previously. Generated vapor during loading is returned to shore by using high duty compressors on board. During loaded voyage, generat- ed boil off gas is heated up and delivered to the main boilers as fuel gas by low duty compressors and boil off gas heater.

The cargo is discharged by electric motor driven sub- merged cargo pumps provided on the bottom of each cargo tank having capacity of 1,700 cu. m./hr. and sup- plement gas is received from shore or onboard LNG vaporizer in emergency during discharging operation to maintain cargo tank pressure.

The ship is provided with a emergency cargo pump for emergency cargo discharge, in case of both two cargo pumps in a tank fail at a same time. During bal- lasted voyage, small amount of cargo heel will be left in the cargo tank for maintaining a cold condition with cool down of cargo tank.

Besides, a Central Control Room (C.C.R) which is arranged in the accommodation deck allows the cen- tralized control of loading, discharging, ballasting, de- ballasting and continuous monitoring and control of the cargo handling system. Main propulsion machinery of the ship consists of a marine steam turbine driving a single propeller through double reduction gear and two(2) sets of main boilers of the gas/oil dual burning type. The engine room machinery is remotely controlled from the wheelhouse and

C.C.R. Unmanned operation of the main engine is available during sea going.

Circle 244 on Reader Service Card "World's Largest" Heavy Lift Ship Enters Service

Heavy lift specialist Jumbo enters its heavy lift vessel MV "Jumbo

Javelin" newbuild into service this week after having been mated with cranes successfully and pass- ing final sea trials in the North

Sea. With its 1,600 tons lift capac- ity, a hold space of 19,000 cu. m. and a main deck of 2,650 sq. m.,

MV Jumbo Javelin is without con- test the largest heavy lift ship in its class in the world. She is the first in a series of two new ships ordered by Jumbo. MV "Jumbo

Javelin" will be joined by its twin sister vessel MV Fairpartner in

September. The ships will boost the Jumbo fleet to a total of 12 units. On its commercial maiden voyage Jumbo Javelin will load a combination of power plant material and petrochemical equipment from Dutch and Italian ports for destinations in Bahrain, Qatar and Iran. The heaviest cargo item is a reactor column - weighing 620 tons weight and measuring 61.06 x 9.736 x 9.878 m - destined for the styrene monomer plant of the ninth olefin project in Bandar Assaluyeh, Iran. 26 Maritime Reporter & Engineering News
