The requirements for a multifunction support vessel are unique to the individual operations to be carried out, and specifications include those necessary for dynamic positioning, firefighting, cranage and a comprehensive saturation diving system. Development of these specifications resulted in a dynamically positioned column stabilized semi-submersible vessel equipped with the following unique features: Extensive on board maintenance facilities for support of platform production and maintenance operations; A dynamic positioning system suitable to D.P. on all sides of a burning platform in Beaufort state 10 while effectively fire-fighting; Fire-fighting equipment to provide for fire control, platform abandonment, and remote manipulation and removal debris associated with such disasters; A sixteen man saturation diving system, featuring a tethered and manned Mobil Diving Unit. This unit is capable of traversing considerable horizontal distances from the M.S.V. under its own propulsion, and contains an atmospheric chamber for shirt sleeve environment occupancy by engineers. A continued and on-going requirement in the North Sea for such sophisticated support vessels is realised, and particular observations are made of their strategic locations and future uses.
