    Abstract: For lifting from deep sea beds a pipeline trunk, a device is disclosed which is composed by a compact framework of square outline which supports a sealing and pulling head and paired jaw assemblies having sloping surface seats to engage the outer surface of the pipe to be lifted, said jaws being actuated by hydraulic and pneumatic motive means so as to grip the pipe surface firmly. A pipe-cutting device is also provided, which has two discrete cutting units, and the sealing and pulling head is removable from said frame and can be both slid and rotated as to position it correctly coaxially with the pipe trunk.

    Abstract: Apparatus for supporting pipe suspended over depressions in the sea bed and method of, comprising a service modular unit capable of being completely recovered and another modular unit intended for properly supporting the pipe: the two modular units are so connected that they can be disjointed under a command from the pipe-laying barge. The service modular unit is equipped with a recoverable assembly for placing the supporting modular unit in a correct vertical posture on the sea bed and for vertically holding such supporting modular until the pile-driving operation has been satisfactory completed.
