Diverse Welding Services complete Subsea Structural Fabrication for Oceaneering

Subsea Structural Fabrication


DWS has been contracted by Oceaneering Australia to complete the fabrication of (1) subsea mud mat structure & deck table.  The mud mat & deck table are part of a specialised subsea umbilical work scope being undertaken by Oceaneering Australia for a key oil & gas client in Western Australia’s Northern Water Oil & Gas Fields.  Oceaneering Australia completed its engineering work scope within its new oilfield services facility in Jandakot, Western Australia, a purpose-designed 40,000 square meter site, which was developed to provide highly specialized support services to Australia's oil and gas industry. 

DWS completed the structural fabrication of the Oceaneering engineered & designed equipment to AS1554.1.  Our work scope also included a comprehensive Quality Assurance package including material qualification & traceability, weld procedure & personnel qualification, and NDT (Non Destructive Testing) including UT (Ultrasonic Testing), MPI (Magnetic Particle Testing) & Visual examination of the weldments.

The largest structure, the mud mat, was approx. 10 meters (m) in length by 2.4 meters (m) wide, with a mass of 2.6 tonne (t).

This project was completed in DWS’s new Mining, Oil & Gas Facility located at 14 Arvida Street Malaga.  DWS supplied the fabricated structures to Oceaneering ready for painting and load testing prior to deployment.

Diverse Welding Services thanks Oceaneering for the opportunity to complete this work scope & looks forward to future projects.
