... ABSTRACT: Offshore pipelines are usually protected by installing rock berms, mattresses or mechanical backfilling of a trench. This is to protect the pipelines from dropped objects, fishing gear interaction, vessel anchors, icebergs and provide resistance to operational pipeline loads induced...

... ABSTRACT: The seabed resistance may be a key factor affecting offshore pipeline retrieval at a time of decommissioning. However, there is little guidance on the adequate characterisation of the pipe-seabed interaction (PSI) during retrieval. Of particular importance is the pipe-seabed contact...
