RCV-225G: Design and production of a first unit wellhead work system

Market studies by Hydro Products identified industry interest in a guide wire deployed package consisting of an RCV-225 remotely controlled vehicle with launcher and a strong dexterous manipulator for drill ship support in water depths to approximately 2000 ft ( m). This paper discusses the design, production, and initial testing of a prototype unit. Anticipated capabilities provided for in the initial design include the ability to perform pre- and post-drilling site surveys, wellhead and riser television inspection, stabbing assist, AX/VX ring replacement, guide wire replacement assist, and debris removal. Provision for incorporation of further sensors and capabilities was given high priority. Future developments and plans for further testing are also enumerated.
