SUBMERGED AIR CUSHION (SAC) VESSEL - THE APPLICATION OF THE AIR CUSHION PRINCIPLE TO VERY LARGE VESSELS - THE CASE FOR FURTHER RESEARCH

The object of the submerged air cushion is to decrease viscous resistance by introducing a captured air cushion beneath the hull of the vessel. It is applicable to very large vessels such as bulk oil and ore carriers with large block coefficient and large flat bottom area. Model tests show that it may be possible to reduce the total resistance of a fully laden 200,000 tons deadweight tanker by approximately 17% at service speed, and by extrapolation of the results so far obtained, a reduction of 25% on vessels of 400,000 tons deadweight may be possible at fully laden draft and a reduction of 35% in the ballast condition; an increase in service speed would be available for a specific power output.
