摘要： A method and apparatus for excavating cohesive material comprises directing a jet of fluid (12), for example water, at a cutting face (13) of the material and along spaced apart tracks to cut spaced apart slots and thereby to create a kerf between the two slots. The invention is particularly applicable to the excavating trenches for sub-sea cables and pipes to be laid in.
