Shutdown and outage crews that finish on time
Shutdowns are planned to the hour. WJC supplies boilermakers, pressure welders, mechanical fitters, dogmen and riggers who are inducted, ticketed and ready to work to your outage schedule at power stations, mines and gas facilities.
Shutdown scopes we support
- Air heater, furnace and boiler overhauls
- Mill, conveyor and fixed plant overhauls
- Duct work, expansion joints and structural repairs
- Pressure welding on boiler tubes, headers and pipework
- Valve, pump and pipework replacements
- Rigging, dogging and component handling
Crews or complete scopes
We can take on a complete work package or supply skilled tradespeople to join your site team. Either way, our people arrive with their own tooling and PPE, so there is no downtime while kitting out.
Our welding is certified to AS 1554.1 structural steel, AS/NZS 3992 pressure welding and AS/NZS ISO 9606-1 welder qualification, with independent weld inspection.

Common questions
Can you supply labour for a shutdown only?
Yes. We supply boilermakers, fitters, riggers, dogmen and trade assistants for shutdowns, or we can deliver a complete scope.
Are your people inducted and medically current?
Our crews hold Standard 11 surface mining induction, coal board medicals and high risk work licences, and we complete site-specific inductions before mobilising.
