At Blacktip, the Perth-based company will supply, fabricate and assemble about 3000 tonnes of process modules, as well as provide logistics, hook-up and pre-commissioning of the onshore gas treatment plant.

These works will be undertaken in Darwin and Wadeye in the Northern Territory from now until January 2009.

The Blacktip gas field is about 110 km off the NT coast in the Bonaparte Basin.

Monadelphous’ second contract concerns the BP refinery on Bulwer Island in Brisbane, where it will provide mechanical, electrical and instrumentation services for capital improvement projects.

The contract is performance-based and has an initial term of five years.

Monadelphous Group managing director Robert Velletri said these latest contract wins, worth a total of $140 million, in the oil and gas sector demonstrate the company’s strategic focus on growing its presence in this market was continuing to achieve results.

“These contracts show that Monadelphous is now being seen as a serious contender in oil and gas,” Velletri said.

“This is the second maintenance support contract we've won with BP in recent months, the other being at the BP Kwinana refinery in Western Australia.

“The contract with international oil and gas giant ENI will be our first major construction project in this market and we are really looking forward to working on this.”
