PERMANENT MOORING SYSTEM FOR LARGE CONSTRUCTION AND SUPPORT VESSELS IN THE PIPER FIELD

The need for support vessels alongside the platform during construction programmes offshore has focused attention to the problems of mooring and maintaining station in this service. In the past, mooring systems under storm situations have been primarily designed for open ocean applications and have not catered for the requirements of operating and surviving alongside a fixed platform. In addition, anchor handling and dragging of anchors have been the primary cause of damage to submarine pipelines. This problem becomes more acute as the number of vessels around the platform increase and the number of moorings over time becomes significant enough to constitute a hazardous situation. The Piper field, located in the 58 degree north section or the North Sea, experienced these mooring difficulties compounded by poor top soil conditions, which led to the design and installation of a fixed permanent anchor pile mooring system around the platform.
