Carnegie Wave Energy has awarded a contract to Subsea Riser Products (SRP) for the supply of subsea foundation connectors, articulating bearings and tether assemblies for Perth Wave Energy Project.
SRP, an Acteon company, will provide three Rocksteady™ mooring or foundation connectors, with a breaking load (MBL) rating of 2,000 tonnes. These connectors will be part of articulated bearing assemblies in a shallow water depth of 30m, situated off the coast of Western Australia.
This is the first time that a variant of the SRP Rocksteady™ subsea mooring connector will be deployed on such a project, following successful qualification and fatigue testing in 2013.
Mike Ridgway, head of business development, SRP , said: “ This is a significant project award because of the very demanding load conditions of the application. Our 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 SRP. 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. This contract provides an excellent example of how SRP can overcome challenging engineering issues as well as the versatility and quality of the Rocksteady™ subsea connector.”
Alexandre Pichard with Carnegie said: “Carnegie selected SRP for the supply of key cylindrical energy transfer oscillating (CETO) unit components via a competitive tender process that considered proven performance in similar applications, cost and schedule. SRP was very responsive to key selection criteria and demonstrated an appetite to provide an innovative solution to the project requirements.”
Manufacturing and assembly work will take place in the UK and mainland Europe, and the first phase of equipment will be delivered in the first quarter of 2014.
