Paul J Durning, Iain A Rennie, John M Thompson and Edward J Ruckstuhl. This paper was first published in GE’s November 1979 edition.
This paper describes the planning and installation of an offshore platform piled foundation in hard, overconsolidated clay, located north of the 60th parallel in the British Sector of the North Sea. The successful installation of the piles for the steel jacket platform in the Heather field is used as an illustrative example throughout the paper.
Engineering considerations necessary for a successful installation are outlined starting from site selection and carried through the final comparison between pile capacity, pile driveability and pile driving experience.
