ROV Intervention Tooling for the Oseberg Field

Abstract

As more subsea production equipment is installed in deepwater, the importance of effective and efficient remote work system intervention is increased. Typically, the obstacles that restrict intervention are preventable during the design of the subsea equipment. Proper pre-engining of interfaces can allow almost limitless options with respect to what can be accomplished by a remote work system. In addition, subsea equipment interfaces and remote work system tooling can be designed to avoid dependence on a particular type of remote work system for intervention. The design methods and equipment which Ocean Systems Engineering used to achieve these goals for the Norsk Hydro's Oseberg Subsea Satellite Wells System in the North Sea are discussed.
