A safety notice has been issued by the UK's Marine Accidents Investigation Branch to the owners and operators of beam and scallop trawlers.
The move follows two fatal accidents aboard UK vessels whereby chains in the dredging gear quick release mechanisms failed leading to fishing gear falling onto crew members.
