  • Preparing tubing or pipelines for submarine installation
    Patent number: 4110991
    Abstract: Pipe sections or tubing is prepared by enveloping in flexible, rather wide hose, and just prior to submarine installation the space between hose and tubing is filled step-wise with wet or dry cement which will set after the tubing has been laid on the sea or lake floor. Anchoring wires with spacers are provided in that space before filling with concrete and the filled hose is armored with ropes or cables to divide the concrete in a quilt-like manner.
