Between 2009 and 2010, Dextra manufactured and supplied large マリンタイバー for Saipem, which were incorporated into the main quay wall. Additionally, in 2008, Dextra supplied Marine Tie Bars and Waling Beams, connecting the sheet pile walls of the service jetty.

Marine Tie Bar Systems: High-Performance Solutions:
For the main yard, Dextra supplied its Grade 700 マリンタイバー, the highest grade in the range.

  • より高い tie bar grades allow for high performance while reducing the size and weight of the bars, making transportation and installation easier.
  • Grade 700 also enables design optimization, allowing bars to be spaced further apart, thus reducing the total number of bars required for the project.

Connection & Splicing Systems:
To connect the bars to the walls, ball cages were used.

  • When used with a bearing plate embedded in the wall, ball cages allow a multidirectional adjustment angle of 10° for greater installation flexibility.
  • To splice bar segments, couplers were also used, ensuring a strong and secure connection.
