DSL Jetty Decking Case Study

DSL Jetty Alternative Access

The Dampier Salt Ltd, 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 design of the system allowed weight loading to be spread across the pylons rather than hanging from the understructure of the jetty which had been de-rated in recent years due to extensive corrosion.

Dampier Salt Limited (DSL), is located 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. DSL 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. System is being used on a rolling work front basis.

Design of the system allowed weight loading to be spread across the pylons rather than hanging from the under structure of the jetty which had been de-rated in recent years due to the extensive corrosion.

Coating Remediation

Sponge jet technology was utilized for safe removal of the existing coating which contained high levels of lead. This was done with a reusable blast media which is continuously recycled via a selfcontained vacuum recovery system which filters out the fines and lead contaminated waste into sealed 204Ltr drums which are then sealed ready for collection by licenced removalists.

Conclusion

The engineered suspension deck provided an articulate access system to the unique requirements of the
structure and encompassed a fully encapsulated habitat which contained any airborne contaminants from
personnel operating on the jetty and the immediate environment.

Environmental monitoring throughout the entire process showed airborne contaminant levels well below the
recommended national exposure standard. Zero disruption to working functions of jetty thus resulting in No loss of production to the client.
