Constructex have successfully completed strengthening works and corrosion protection works in Southampton. The works were to an existing boat hoist which will now permit the users to lift larger vessels out of the water.
The strengthening works involved the installation of web stiffeners and flange strengthening plates to enable the increased moment and shear forces to be sustained by the existing structure.
The corrosion protection works involved the application of Interzone 954 to the steel work within the tidal zone together with the design and installation of a cathodic protection system. The containment of the works was a high priority, as the marina remained operational throughout.
The design and installation of the cathodic protection system was undertaken by Constructex and included adequate provision for the steel bearing pile and the sheet piles wall. It also accounted for the additional CP drain suffered from additional steel area on continuous sheet piled wall. Anodes were installed by the Constructex dive team. Anodes were fixed to the steel structure by underwater welding using Constructex designed bracket system.
