The layers provide information on the intensity of mobile fishing associated with Oil and Gas pipelines and cables. Each layer was created by calculating the total number of fishing tracks in 1 km by 1 km squares along the length of each pipeline for four gear categories (see More Information below). Fishing tracks were recreated for UK vessels greater than 15 m in length between 2007-2015 operating mobile demersal gear (otter trawls, pair trawls, beam trawlers and dredges) using vessel position data extracted from the Vessel Monitoring System. The layers can be used to aid the pipeline decommissioning process, including assessing the potential impacts and risks of different decommissioning options to commercial fisheries and informing the frequency of post-decommissioning monitoring according to level of fisheries interaction. The layers can also inform risk modelling for operational pipelines.

The layers were created following the methodology of Rouse et al. (2017) ‘Commercial fisheries interactions with North Sea pipelines: considerations for decommissioning’ ICES Journal of Marine Science (https://academic.oup.com/icesjms/article/3972175/Commercial-fisheries-in...). VMS position data were filtered by speed to distinguish fishing from steaming points. Fishing points were interpolated into tracks, accounting for the speed and heading of the vessel, to obtain a greater spatial resolution of fishing activity. Each pipeline was divided into 1 km sections. The total number of fishing tracks, extending 500 m either side of the pipeline, was calculated for each 1 km section according to four gear categories: dredging, nephrops (otter and pair trawls), demersal (otter, pair and beam trawls), and all mobile demersal gear.
