\r\n\r\nVMS position data were filtered by speed to distinguish active fishing from steaming. The point-data 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 (dredging, Nephrops and demersal amalgamated).
\r\n\r\nThe layers will aid the pipeline decommissioning process by facilitating the assessment of the risks associated with different decommissioning options to commercial fisheries. These layers will facilitate determining the optimal frequency of post-decommissioning monitoring according to level of fisheries interaction and risk modelling for operational pipelines.
