ABSTRACT

Offshore caissons are rigid circular steel cans usually vertical and installed by self-weight and suction. Originally for anchor piles, they are now commonly foundations for both fixed platforms and seabed structures. Resistance envelope equations for caissons (embedment ratio L/D > 1), even in uniform soil, are not currently available. Details of geotechnical design considerations are given in a companion paper (Palix et al. 2010).
