Abstract:
The Hibernia Oilfield, 315 km of St. John's, Newfoundland was discovered in 1979. It is located on the Ground Banks in 80 m of water and is estimated to contain about 525 million barrels of recoverable oil. Several options for development of the reservoir were considered before a concrete gravity base structure (GBS) was selected in 1985. The development will cost more than $5 billion and will take approximately 5 years to complete. Major components of its development include: the GBS, which has a diameter of about 108 m and a height of 111 m and contains about 165,000 m 3 of concrete weighing more than 500,000 t; the topsides containing living quarters for 280 people, drilling, processing and production equipment; the offshore loading system; the crude oil transportation tankers; and the drilling of the production and reinjection wells.
