英国大陆架上越来越多的管道达到其经济寿命，导致越来越多的管道退役。退役过程中隐含着对不同退役方案的环境影响的评估，然而对与这些结构相互作用的表层动物知之甚少。该研究首次利用行业收集的远程操作车辆检查管道的录像来评估底栖动物与管道及其相关结构的相互作用。研究人员分析了来自北海北部和中部的录像，以检查动物群落组成与管道及其保护层之间的关系。混凝土和Link-lok床垫复合生境的可观测类群数量最多。群落组成的差异主要是由于常见类的比例不同。管道覆盖类型与邻近基质的物种组成关系不明显。深度和纬度与群落组成的相关性最强。该研究编制了第一个关于北海海底管道与地表关联的数据集。
An increasing number of pipelines across the UK Continental Shelf are reaching the end of their economic life, resulting in a growing impetus on decommissioning. Implicit to the decommissioning process is the evaluation of the environmental impacts of the different decommissioning options, however little is known regarding the epifauna that interact with these structures. This study utilized industry-collected footage from remotely operated vehicle inspections of pipelines to assess the interactions of benthic epifauna with pipelines, and their associated structures, for the first time. Footage was analysed from across the northern and central North Sea to examine relationships between faunal community compositions and pipelines and their protective coverings. The complex habitat of concrete and Link-lok mattresses had the highest numbers of observable taxa. Differences in community composition were largely due to varying proportions of common epilithic species. There was a weak relationship between pipeline covering type and the species composition of the immediately neighbouring substrate. Depth and latitude were the strongest correlators with the observed community compositions. This study has compiled the first dataset on epifaunal associations with subsea pipelines in the North Sea.
