A plough share for a submarine plough for cutting a trench in a sea floor is disclosed. The plough share has a cutting edge (104) for fracturing the sea floor to cut a bottom of the trench, and an orifice (122) is arranged adjacent the cutting edge (104) for directing a stream of high pressure water towards a crack formed in the soil by the cutting edge (104) to assist the cutting edge in fracturing the sea floor. |
