Manufacturing for Subsea Applications

Orontide’s work on a large-scale project for Chevron’s Gorgon Project utilised a diverse range of capabilities from material processing through to fabrication, machining, final surface treatment, assembly and testing.

Manufactured in Orontide’s Bunbury workshop, the Pipeline Buckle Initiator comprised 11 permanent restraint tools weighing 3 tonnes each which were to be fixed to bases positioned on the sea-bed. In addition, Orontide manufactured two displacement tools, deployment frames and transport skids.

NDT and load testing were conducted prior to surface treatment to extend the life of the structures to 40 years on the seabed before Final Assembly and Testing and Site Integration Testing were completed.

Orontide was selected ahead of a number of other companies competing for this work due to its AS 3834.2 accreditation and proven track record in specialist welding.
