Underwater Pipeline Repair in Difficult Seabed Conditions: Problems and Solutions
Summary This paper examines the application of innovative technology to significantly reduce the time for a major repair to a 36 inch diameter buried submarine pipeline. The actual repair is achieved by cutting out the damaged section and inserting a replacement spool-piece. Such operations would be based upon hyperbaric welding which is performed in a dry habitat chamber and is a relatively controlled and straightforward operation. Therefore the research effort was directed towards saving time on the auxiliary tasks such as: seabed excavation, the use of a protective cofferdam, seabed surveying, pipeline weight coating removal and pipeline isolation. It is anticipated that a 40% reduction in the overall repair time is possible with the application of the equipment and methods described in this paper.
