A PLOUGH FOR EXCAVATING A SUBSEA CHANNEL AND A SEA-GOING VESSEL COMPRISING A PLOUGH

摘要

A plough (104) for excavating a subsea channel is disclosed. It comprises an anchor (101) and a spacing arm (201), the anchor comprising a shank (103) and one or more blade (s) (105) rigidly connected to the distal end of the shank wherein the spacing arm is pivotally connected to the proximal end of the shank and which, in use, maintains the proximal end of the shank at a substantially constant distance from the ploughing surface, thereby controlling the depth of the trench cut in the ploughing surface by the blade (s) as the plough travels over the ploughing surface.
