Discussion on measures taken to protect submarine pipelines from hanging
摘要
Abstract
Based on several pipeline surveys in Maoming single point mooring dock (30 104 t oil unloading capacity), we describe the method of identifying the buried state of submarine pipelines and some measures taken to protect them from hanging. Fixing artificial seaweeds to the hanging segments has an obvious effect by slowing the current and promoting siltation. However, the seaweeds can be destroyed by trawls; therefore, this method is not suitable for areas deeper than 40 m due to the large underwater workload of divers during installation. Concrete mattresses slowly promote siltation around hanging pipelines. Gravel dumping can effectively protect submarine pipelines from hanging and is widely used for correcting free spans.关键词
