Abstract: Concrete weight 14 coating on a subsea pipe has slots 82, 84 made in it by means of a circular saw carried by a first apparatus mounted on the pipe. The saw also cuts two spaced circumferential slots. All slots sever all steel reinforcement. The slots have boundary surfaces defining two semi-cylindrical pieces of concrete 15, 17. A second apparatus replaces the first. 
     It has a frame 90 clamped by chains to the pipe outside the pieces 15, 17. Two assemblies 98 adjustably spaced apart along the frame include plates 100 which are forced apart by cylinders 102. The plates 100 are guided downwards by cam tracks 116 and rollers 118 as the plates 120 swing down about pins 126. The plates 100 continue to exert thrust on the boundary surfaces of the slot 84 as the two pieces 15, 17 separate. The thrust on either piece of coating is at least partly reacted against the other so reducing the turning moment on the frame 90.
