2—The Otter subsea equipment layout. March 2004 SPE Drilling & Completion 53 Changeover Switch. Specifically developed for this project, the electrical switch was integrated into the tree-cap assembly. The upper or lower pump was selected by means of the Xmas tree electrohydraulic control system. This switch used standard wetmateable electrical connector technology, requiring that the line be isolated and discharged before activation to the alternative position. Workover Philosophy To optimize the workover costs and uptime, a workover philosophy was developed that supported selection of the dual-ESP system.
The operation benefitted from the installation integration tests and was executed without major problems. Techniques to optimize operations were identified for subsequent wells and were integrated into the completion program. Completion of the Second Well. In November 2002, operations commenced to complete the second well. This appeared to proceed without problems. However, during makeup of the tubing hanger, the weather deteriorated significantly, and the main power cable was damaged at the wellhead level.
