FELS To Construct Semisubmersible Rig For Western Company
Far East-Levingston Shipbuilding Ltd. (FELS) has signed a contract to construct a semisubmersible d r i l l i n g p l a t f o r m for Western Company of the U.S.
Scheduled for delivery in mid- 1983, the self-propelled drilling vessel will have dimensions of 260 feet by 200 feet by 116 feet and a twin ship-shaped hull supporting six caissons and a rectangular elevated deck.
The deck will have single-level machinery houses, two-level quarters with helideck, and a substructure with derrick. The quarters will have facilities to accommodate 92 offshore personnel, and will be provided with both cooling and heating systems. Three revolving cranes will be installed, and the vessel will be moored by four double-chain windlasses with eight anchors.
The vessel will be fabricated to meet all regulatory requirements of the American Bureau of Shipping and the U.S. Coast Guard, and is designed to operate in water depths from 150 feet to 1,500 feet. It will be built to take a maximum deck load of 4,000 long tons with capability of surviving storm conditions at a d r a f t of 50 feet under 100 knots steady wind, 1.5 knots current, and 100 feet maximum wave height.
At present, Western Oceanics, Inc., a s u b s i d i a r y of Western Company, is having two of their jackups built in FELS. The jackups, which form part of the six Friede and Goldman L-780 design jackups currently under construction in FELS, will be among the first jackups of this design to be operational in the world. They will be christened Apollo I and Apollo II.
