We have recently completed an extensive refurbishment of 35 navigation aid beacons for the Port Hedland Port Authority (PHPA).
PHPA required refurbishment of 35 existing channel markers to extend their current serviceable life while providing safe access to the top of the channel markers for maintenance in accordance with Australian Standards.
The project was made extra challenging by such a remote site, extreme heat, exposed offshore conditions, and 2 cyclones thrown in.
The work basically involved cutting off the existing piled beacons down in the tidal range, welding on a new flange and paint repairing. To this flange we then attached a new "top", which were all pre-fabricated in Townsville and taken over on the barge.
The following activities were required:
- Surveyed beacons
- Prepared shop drawings
- Provided engineering solutions
- Procure material
- Fabricate beacon tops
- Fabricate beacon furniture and osprey platforms
- Blast and paint steel work
- Galvanize required steel elements
- Load items to 230ft long barge
- Delivered items to site
- Replace old, redundant beacons, with new AS compliant beacons
To perform the works on site PMG used two tugs, several smaller vessels, 230ft long flat top barge equipped with 70T crawler crane and other specialised equipment. Up to 30 crew members on site and a support team in Townsville made it possible. Marine crew, divers, construction team, painters, project management, admin, fitters, boilermakers - this job used nearly all PMG departments.
