OUTSTANDING

SHIPS

This year's portfolio of out-standing oceangoing ships includes a diverse lot, each one boasting its own distinc- function or design. From the ice breaking research vessel, Nathanial

B. Palmer built by North American

Shipbuilding, to the ore carrier

Bergeland constructed by Hyundai

Heavy Industries, to the aircraft carrier George Washington from

Newport News Shipbuilding, the list includes many fine vessels from yards around the world.

Due credit is given to the yards and equipment suppliers which helped create the best oceangoing ships of 1992.

Delivered in January 1992 to

Conoco Shipping Company of Hous- ton, the M/T Patriot is a 95,000-dwt, double-hulled crude oil tanker with an overall length of 243 meters, a beam of 42 meters and a draft of 12.2 meters

Propelled by a Sulzer 6RTA62 engine, which has a total of 15,000 bhp at 104 rpm, the Patriot has an average speed of 15 knots.

Additionally outfitted with Nil thrusters, thruster engines and re- duction gears, as well as an (Ni-Al-

Br) fixed-pitch propeller, the vessel has a cruising range of approxi- mately 19,000 nautical miles.

To ensure minimized wave resis- tance with optimized bulbous bow and lower viscous resistance, nu- merical analysis, such as flow-line visualization, pressure distribution around the hull and wave pattern analysis were carried out to ensure optimum hull form.

To enhance performance, the ship was equipped with: three generator sets, capable of 720 kW, and a 150 kW emergency generator; an SSHI

B&W 6L23/30 engine, rated at 1,060

PS at 720 rpm; engine controls oper- ated remotely from the bridge and from the engine control room; electro-hydraulic steering controls, two-RAM, four-cylinder type; and two vertical water tube type auxil- iary boilers capable of producing 30,000 kg/h x 16 bar.

Deck machinery consists of two electro-hydraulically driven wind- lasses and eight winches.

The crude oil tanker, which is deployed in the Gulf of Mexico, is classed ABS, +A1, (E), "Oil Carrier," +AMS, +ACCU, and runs under the

Liberian flag.

Accommodations on the Patriot are designed and arranged for a complement of 31 in single cabins with private shower and toilet fa- cilities.

The firefighting system is a cen- tralized C02 type, for engine room and cargo pump room, and foam for the cargo deck area.

The hull was coated with a tin- free, self-polishing A/F paint to maxi- mize both environmental and hull protection.
