This is the first time a variant of SRP Rocksteady subsea mooring connector will be deployed on such a project.

The scope of the contract includes three Rocksteady mooring or foundation connectors with a maximum breaking load rating of 2000 tonnes.

They are part of articulated bearing assemblies in a water depth of 30m off the coast of Western Australia.

Manufacturing and assembly work will take place in the UK and mainland Europe. The first phase of equipment will be delivered in the first quarter of this year.

The Carnegie project will be the first wave-power application in the world to operate with multiple wave-power convertors in an array and the first to produce clean power and fresh water.

Carnegie's Alexandre Pichard said the company selected SRP for the supply of key cylindrical energy transfer oscillating unit components through a competitive tender process.

That process considered performance in similar applications, cost and schedule.

SRP head of business development Mike Ridgway said the Rocksteady connector's performance, particularly its automatic latching and resistance to bending, torsion and compression, was a key factor in the Carnegie decision to source from them.

"The restricted space available for the connector also required some clever engineering to achieve the client's specification, including redevelopment of the locking mechanism from a mechanical system to hydraulic hot stab," he said.
