Project Data

The LADS Passage Navigational Aids Repair Project involved restorative work to four separate structures damaged during Cyclone Trevor in March 2019. This comprised of three – one pile beacons and one larger 4-pile structure on Robin Reef. 

Denso Australia worked closely with the successful design team upon award to meticulously plan the jacket configuration for each structure considering existing clamps and tie backs causing jacketing obstructions. 

In addition, Denso had to engage with a specialist plastic manufacturer to design and produce 3 x long term protection covers to protect transition zones on each of the single beacon structures. These were designed to compliment the SeaShield 2000FD™ system to protect a section where the piles transitioned in size, reducing from 1225mm to 920mm. 

The Denso Steelcoat 100™ system was utilised in sections where existing brackets obstructed a jacket application whilst SeaShield™ SplashZone UW Epoxy was used to seal existing fender clamps, creating a transition for the SeaShield Series 2000FD™ system to be applied to. 

Overall, it was a very successful application that will ensure an excellent level of corrosion protection for these vital assets, providing continued safe navigation through the northern section of the Great Barrier Reef.
