ABSTRACT
The use of suction caissons is envisaged for stabilizing a vessel
equipped with cranes. It would be possible to maintain the suction for
the relatively short period that the anchoring load is needed. The
research objective was to investigate how much additional uplift
capacity this might yield. Furthermore, various configurations of
suction caissons were determined, with due regard to the constructional
possibilities. The uplift capacity during suction was determined in tests
carried out at 1g and in the geotechnical centrifuge of the University of
Delft. The test results were compared with numerical simulations. It
was found that a reasonably-sized anchoring system is able to yield the
required anchoring capacity.
KEY WORDS: ship stabilization, offshore foundation engineering,
geotechnical centrifuge research.
