Subsea plough for burying a flexible elongate member

A plough for forming a trench in a seabed, the plough comprising a chassis and having a longitudinal axis;

• wherein in a first configuration, the plough comprises:
• a share coupled to the chassis;
• a boulder clearance member, comprising a boulder clearing surface, provided towards a first, leading end of the plough, for clearing boulders from a plough path, extending between a port side and a starboard side of the plough, and urging the boulders from the plough path to a first distance away from a longitudinal centreline of the plough;
• a spoil clearance member provided towards a second, trailing end of the plough, for clearing spoil from the plough path, and urging the spoil from the plough path to a second distance away from the longitudinal centreline of the plough, wherein the second distance is less than the first distance;
• a front support surface and a rear support surface;
• and wherein in the first configuration, a maximum span of the boulder clearance member in a first position is greater than a span of the spoil clearance member,
• wherein in the first configuration, the boulder clearing surface extends from a first distal end of the boulder clearance member located the first distance away from the longitudinal centreline of the plough, on the port side, to a second distal end of the boulder clearance member located the first distance away from the longitudinal centreline of the plough, on the starboard side.
