NAVAL ARCHITECTURE CONTRIBUTION TO THE TRANSPORTATION AND INSTALLATION OF THE NORTH SEA FORTIES FIELD PLATFORMS

Fabricated tubular steel jackets are used for support of the Forties oilfield platforms to operate in North Sea locations, at water depths up to 416 ft. Transportation and installation of these units, by conventional methods, would have led to unacceptable compromises in structural design and piling requirements. The weight to buoyancy ratios of the installed jackets were significantly in excess of unity, requiring unusual arrangements of temporary auxiliary flotation. The role of naval architecture was established in this undertaking, as an exercise of integrated responsibility. It provided the techniques and expertise required in the development and implementation of safe, predictable procedures for installation. The important results of extensive model tests and analytical work are provided as a compendium of experience in this paper. It illustrates the relative background of knowledge against which engineering and operational decisions were made. The data are qualified in the text with regard to their source and derivation; also comparisons are made with the full scale experiences in appropriate sections.
