EVALUATION OF AIR-WATER INTERFACE VEHICLES FOR TRANSPORT OF PERSONNEL TO THE OILFIELDS IN THE NORTH SEA
This thesis estimates and compares the efficiency of different air-water interface vehicles for the transit of people to and from the oil fields in the North Sea. The seakeeping performance of 12 different vehicles; 2 monohulls, 4 SWATH's, 3 hydrofoils and 3 air cushion vehicles, is assessed. These vehicles are then simulated on a basic transport mission with given weather conditions and performance parameters relative to this mission estimated. The transport demand of the Ekofisk field in the Norwegian sector of the North Sea is used to define the basic mission, and weather statistics for the area are used to make a probabilistic weather model. The hydrofoil emerges as the most attractive vehicle for the transit phase of the assigned mission. This thesis treats only the transit phase of the total personnel transport mission. Technical systems for the transfer of people from the vehicles to the platform are not treated; they must be designed and their costs incorporated into the transit cost. Currently helicopters are used for this transport service, and if the regular transport service in the future is made by other vehicle types, helicopters will still be needed for unscheduled transits.
