Worldwide offshore oil production (excluding the Soviet bloc) was about 10 million bbl/day in early 1975, or 18% of the total world production of 55 million bbl/day. By 1985, offshore production should increase to 30 million bbl/day or 40%. To accommodate this increased drilling and production, 100 major offshore platforms will have to be built each year at a total 10-year cost of $53 billion. Cost for the 3 basic types of production platforms (gravity, tension-leg, and pile supported) are comprised of construction (50%), installation (30%), and production equipment (20%) and are affected most by water depth. North Sea platforms designed for deep, hostile waters each cost about $125 million to construct; thus, the North Sea 10-yr requirement of 150 more platforms will cost over $36 billion. At least $13 billion will be spent on the 650 platforms needed to produce North American offshore fields.
