Strukton adapts immersed tunnel techniques for Monaco jetty maintenance

23 Oct 15 Strukton Immersion Projects has been appointed to develop a sealed ‘habitat’ to enable underwater inspection and maintenance at the Port of Monaco.

“Our extensive experience with immersing tunnel elements, enabling tunnel repair works by developing habitats and cofferdam constructions all comes together in this project,” said senior project manager Peter van Westendorp.

A ball-and-socket joint connecting a floating jetty to the quay needs its 10-yearly maintenance. The floating jetty serves as a breakwater allowing safe entry enables large yachts and vessels to enter the port. It also accommodates parking for 600 vehicles for yachts and vessels.

Strukton Immersion Projects, working with NFM Technologies, has developed a system to ensure the safety of the people performing the maintenance of the ball-and-socket joint. The habitat that it has developed is equipped with inflatable seals, which have been developed together with Trelleborg. “Our solution was tailor-made for the customer to prevent obstruction to the end users and make safety prevail,” said van Westendorp.

The contract was awarded by the Monaco Public Works Office and work will be carried out in the summer of 2016. Traffic will be able to continue to operate on and around the jetty and the shipping and cruise terminal will not be affected.
