US contractor McDermott has won a contract to carry out decommissioning work at offshore infrastructure owned by Santos offshore Australia.

McDermott said the contract was “sizeable”, which the company defines as amounting to above $1 million in value.

The work will involve engineering, procurement, removal and disposal of Santos’ Campbell platform, part of the Varanus Island Hub infrastructure offshore Western Australia.

The contract is the fourth decommissioning project McDermott carried out in Australia in the past two years, it said.

The scope of the contract comprises project management and engineering services for the removal and transportation of the Campbell platform's topsides, substructure and associated items to an onshore facility, where it will be dismantled and disposed of.

For the project, McDermott will draw from its existing teams in Australia, Indonesia and Malaysia, the company added.
