Abstract

The invention relates to a sub-sea trenching machine (16) including two cutter units (26a, 26b). The cutter units are preferably chain cutter units. The cutter units are mounted to be moveable from a use position in which the cutter units are juxtaposed or spaced a limited distance apart to a stowed condition in which the cutter units are sufficiently spaced apart to allow mounting of an elongate workpiece (18) such as a pipe or cable onto the trenching machine.
