FLEXIBLE MEMBRANE SUPPORTS FOR JACK-UP RIGS

Jack-up rigs are frequently sited on soft soils and the spud cans have to penetrate deep into the sea bed to develop sufficient bearing capacity. A number of problems can occur in these circumstances, including difficulties in retracting the rig legs when moving off station, reduction of air gap etc. This paper describes a research project ro reduce leg penetration in soft soils by supporting the spud cans on flexible membranes on the sea bed, thus creating a 'surface tension' effect which spreads the leg loads over a large area. Details of experimental work undertaken in the project are presented.
