INTERNATIONAL OFFSHORE TECHNOLOGY mmH designed and engineered by a team made up of personnel from Shell,

Amoco and Exxon, with support from outside contractors

Completely assembled, the TLP is 3,570 ft. high, from seafloor to the crown block of the drilling rig. The steel weight of the TLP is approxi- r mately 41,000 tons.

The TLP was designed to simul- taneously withstand hurricane force waves and winds.

The hull — which weighs approximately 15,000 tons — is comprised of four circular steel columns, 66.5 ft. in diameter and 165 ft. high, and a rectangular cross section ring pontoon 27 ft. wide and 24.5 ft. high.

Fabrication of the hull was com- pleted in October 1996 by Belleli

S.p.A. in Taranto, Italy and the hull arrived in the Aker Gulf

Marine yard near Corpus Christi, \

Texas in November 1996.

The deck is composed of five modules: wellbay, quarters, process, power and drilling.

The deck is an open truss/deep girder design, 245 x 245 x 40 ft. high, and weighs approximately 8,100 tons.

McDermott International, Inc. in Morgan City, La. built the mod- ules. There are 12 tendons, three connected to each corner of the platform, each with a diameter of 28 in. and a wall thickness of 1.2 in. Each tendon is approximately 3,145 ft. long, and the total weight for the 12 tendons is approximate- ly 10,000 tons.

The TLP foundation system is comprised of 12 piles driven into the sea floor to which the tendons are attached by means of tendon receptacles. Aker Gulf Marine built the tendons and piles in

Corpus Christi.

There are 20 well slots, and the well layout on the seafloor is arranged in a rectangular pattern approximately 60 x 80 ft. The TLP supports a single modified API platform-type drilling rig (leased) equipped with a surface BOP and high pressure drilling riser. There is complete separation, dehydra- tion and treatment facilities designed to process 60,000 barrels of oil and condensate per day, plus 200 million cu. ft. of gas per day and 30,000 barrels of produced water per day.

The total platform height from the keel bottom to the top of the drilling derrick is 467 ft. and the drilling rig can drill to depths of 19,000 ft. below the sea floor.

Applying Arctic Technology in Russia

Each year, Exxon invests more than $500 million in R&D.

Exxon technology that was first developed for projects in Canada and the Alaskan Arctic is now at work in far eastern Russia.

Operations offshore Sakhalin

Island can encounter earthquakes and moving ice ridges.

Plans for the Sakhalin I fields include innovative structural designs that can withstand these conditions.

This would make the Sakhalin I area the world's first year-round drilling, production and oil trans- port system in offshore arctic regions.

KEEPS YOU GOING

In the operation of modern ships, cruise or cargo, oil is a very important component, involved in propulsion, lubrication, and po- wer transmission. So keeping your fuel, lub oil, and hydraulic oil clean is essential if you want a safe, troublefree voyage - and if you want your machinery to live longer.

Having designed marine oil filter systems for 45 years we should know...

Fuel and lub oil

In the heavy end of the CJC range you find special units for the fil- tration and conditioning of heavy fuel, camshaft and piston rod lub systems on large, two- stroke diesels.

Here a heavy fuel unit for an MAN B& VV engine.
