ABSTRACT

A companion paper (Evans et al., 2010) describes the development planning for the Clair field and the strategy adopted by BP and their co-venturers in assuring foundation design under unprecedented geotechnical conditions. The four legged Clair Phase 1 jacket was installed with 3 or 4 2590 mm o.d. × 85-95 mm w.t. tubular sleeve piles driven per corner.
