Dalrymple Bay Infrastructure (DBI) has overall ownership of the Dalrymple Bay Coal Terminal located at Hay Point, south of Mackay, QLD. The marine component of the infrastructure on site consists of two jetties, each extending approximately 1.6km offshore, terminating at four coal loading berths. There are a total 1,706 piles comprising a mixture of structural jetty piles, berth piles and mooring dolphins. 

Denso’s SeaShield Series 2000FD™ System was selected as the preferred option for the long-term corrosion protection for DBI’s marine assets following a rigorous evaluation process. 

The application program began in 2014 and has been continuously progressing since then, having now protected over 1,000 piles – a milestone reached in October, 2021. Each pile is 1200mm in diameter and coverage requirements extend from 5m on the berthing dolphins to 13m on the jetty and wharf piles. 

Since commencement, Denso Australia has supplied over 18.5 tonnes of SeaShield™ Primer, 28 kilometres of Denso Marine Piling Tape™ and 4,200 SeaShield Series 2000FD™ jackets. 

Failure is not an option on this project. The cost of arranging access to get back to repair a jacket can be more than ten times the cost of the initial wrapping of the whole pile. 

Our jackets are produced in-house from our manufacturing facility in Campbellfield, Victoria. Denso Australia are committed to ensuring consistency of production and rigour in our manufacturing quality assurance processes so that our products and systems remain of the highest quality and can be relied upon by our customers.
