Objective The objective of the Subsea Submersible Pumping project was to develop a system whereby Electrical Submersible Pumps (E.S.P.s) could be safely and economically installed in a subsea completed oil well. The key problem areas addressed were the feed through the tree, of the high electric power, for the downhole E.S.P. and the development of subsea wet mateable electrical connectors.Both electrical connectors have undergone extensive testing and are considered to be fit for purpose. Long term endurance testing is also planned.The project was conducted in four phases.TASK SERIES 1000 - EQUIPMENT REVIEWThis phase comprised of an in depth review of commercially available equipment for consideration by the project. This included submersible pumps, power connectors, wellhead and tubing hanger designs, tree configuration and options and workover requirements.TASK SERIES 2000 - CONCEPTUAL STUDYThis phase of the project consisted of a conceptual design study for all elements of subsea submersible pumping installations and comprised of the preparation of design specifications, system schematics and various layout options for the equipment.TASK SERIES 3000 - DETAIL DESIGNThis phase of the project consists of solving the technical problems identified in the conceptual study.Detailed engineering drawings and specifications were generated for the Horizontal style subsea tree its interfaces with the electrical connectors and the workover equipment.The designs permit two methods of pump deployment, firstly the tubing run E.S.P. and secondly the cable deployed E.S.P.Workover procedures and failure mode effects analysis were conducted to identify and resolve any problem areas. TASK SERIES 4000 - COMPONENT MANUFACTURE AND TESTThe component identified as having the highest technical risk in the system was the subsea wet mateable electrical connector. A functional and technical specification was given to two electrical specialist companies to design and prototype build and test connectors for the application. These connectors have been built and fully tested.
