OPERATIONAL EXPERIENCE WITH DYNAMICALLY POSITIONED DIVING SUPPORT VESSELS

Experience over the last few years has ranged from the Stadive to converted supply boats; from a semi-submersible with the world's largest civilian diving spread, provided with twin moonpools and a manned lockout submersible, to a single chamber diving system with a bell lowered over the ship's side. What all these vessels share is the requirement to operate with full redundancy, so that any single failure <mechanical, electrical or instrumental> will not result in a loss of station keeping capability or at least not until the divers have been safely retrieved. The author describes how procedures and standards have been developed both to determine the safe level of redundancy for any prospective or existing DP diving vessel and to assess the capability of a new custom-built vessel.
