Trench cutting apparatus
A trench cutting apparatus (2) for cutting a trench in the sea bed supporting a pipe is disclosed. The apparatus comprises a tractor (8) and tracks (14) for engaging the sea bed and supporting the tractor. A first chain cutter (18) for cutting a first trench portion in the sea bed on a first side of the pipe cooperates with a second chain cutter (20) for cutting a second trench portion on a second side of the pipe and the first and second chain cutters are spaced from each other in a direction of travel of the apparatus, such that the first and second chain cutters cooperate with each other to form a trench (28) below the pipe while leaving uncut sea bed material 34 between the pipe and the trench. The first and second chain cutters are provided with jet outlets (32) for cutting uncut material of the floor between the trench and the elongate object.
