TEMPORARY WORKS DESIGN UK LIMITED

To construct a new CMAT berth at the new terminal for the Port of Tilbury, TWD developed a method to install a subsea 330m-sheet pile wall. To accomplish the installation, we designed the sheet guiding structure in between two rows of floating modular pontoons, which also served to provide access for personnel, irrespective of the tide. Our marine team performed stability and relative motion assessments of the two pontoons. For this project, TWD also delivered a hydraulically actuated tubular pile gate to install the dolphin structures.

Project highlights:
-Opening the gate around the hinge and floating to the next position easily repositions the designed structure
-It keeps its position using side-released-temporary spud supports or against previously installed long sheet piles
-The piling operations required less handling on-site and safely increased the piling rate
-TWD also designed a barge-mounted dolphin gate that can install multiple tubular piles
