TH7261B - Equipment for the arrangement of the pipeline as close to the vertical - Google Patents

Abstract

Equipment for placement of pipelines as close to the base offshore verticals. Supports and operational frameworks aboard the operational vessel to accommodate the alignment tower, which is bounded It extends upward from the base section and is designed to accommodate the extension pipe that will need to be attached. The tower supports the weight of the pipe will be installed on the support. The supporting tower will have a zone extending downward from the support into the water block. The motion is made to be suitable for movement along the length of the tower to move. At extension tubes and pipelines higher and lower, a platform that can be moved between open positions and Closed position to support the pipe section from the moving block and serve as a support or support. The weight of the pipeline is positioned close to the bottom of the tower truss. Alternatively, beams can be used to clamp the extension pipe from the pipe support frame and pass the pipe into the Alignment tower to attach the pipe to the tower's boundary support pipe. Support protrusion extends into the water eliminating the need for a sticker for its mounting position and scope. The tower extending into the water lowers the center of gravity of the device.
