The Dampier Salt Ltd. engineered suspension deck provided a complete encapsulated working area for blasting and paintwork. The system is being used on a rolling work-front basis.
The system’s design allowed weight loading to spread across the pylons rather than hanging from the jetty’s understructure, which had been de-rated recently due to extensive corrosion.
Dampier Salt Limited (DSL) is in Western Australia and comprises three solar salt operations: Dampier, Port Hedland, and Lake MacLeod. DSL is the world’s largest exporter of seaborne salt, with the capacity to produce approximately 10.3 million tonnes every year. It is a joint venture between Rio Tinto (68% ownership), Marubeni Corporation (22%), and Sojitz (10%).
Access Solution
The engineered suspension deck provided a complete encapsulated working area for blasting and paint works to be carried out. The system is being used on a rolling work-front basis.
The system’s design allowed weight loading to spread across the pylons rather than hanging from the jetty’s understructure, which had been de-rated recently due to extensive corrosion.
Coating Remediation
Sponge jet technology was utilised to remove the existing coating with high lead levels safely. This was done with reusable blast media, continuously recycled via a self-contained vacuum recovery system. The system filters out the fines and lead-contaminated waste into sealed 204Ltr drums, which are then sealed and ready for collection by licensed removalists.
The engineered suspension deck provided an articulate access system to the unique requirements of the
structure and encompassed a fully encapsulated habitat that contained any airborne contaminants from
personnel operating on the jetty and the immediate environment.
Environmental monitoring showed airborne contaminant levels well below the
recommended national exposure standard throughout the process. Zero disruption to working functions of the jetty, thus resulting in No loss of production to the client.
