|SeaShield 500™ System
Denso Canada has been involved in a very successful SeaShield 500™ System project in Eastern Canada for the Department of National Defense. Located in Halifax Harbour, the project consists of the installation of our Series 500 system on timber piles for a marine railway, used for moving vessels into dry dock and back into the harbour for assignment again.
The SeaShield FRP Jackets™ for the job were manufactured in our Houston, Texas division and shipped to the site while the SeaShield 550 Epoxy Grout™ component was shipped to the job site from our Toronto division.
The project involved the protection of over 120 timber piles with diameters ranging from 11”–17” and a variety of lengths due to water depth. The job was handled by a team of divers and consisted of pumping the SeaShield 550 Epoxy Grout, using a peristaltic pump on the surface, into the annulus between the timber and the SeaShield FRP jacket.
Quite separately from the SeaShield 500 System work, there was a large component of petrolatum tape wrapping on rectangular timber headers and cross-bracing that sat above the circular timber piling and under the wharf decking.
The FRP jackets were cut to a variety of lengths on site and two-piece injection ports were installed along with pile stand-offs before being taken below the surface for installation around the piles and subsequent filling.
