Borizontal has been engaged to manage the retrieval of a 600 m long section of a 780 m long 56″ gas pipeline in Germany. The pipe was abandoned temporarily in the hole in March after a rig failure during pullback.
A winch spread consisting of a 800 Te linear winch in combination with a 1,600 Te sheave block will be set up. A TT-Apollo hammer will be installed in the pipe to provide necessary energy for initial movement. Loads of sheetpile and steal beams will ensure a firm anchoring for both the winch and the dead line.
The pipe was recovered early May. After some coating repair and hole cleaning the pipe was re-installed late May without any probems.
