OSD’s Role

  • Design & Construction
  • Pipeline Project Management
  • Procurement
  • Safety & Operating Plans
  • Commissioning


The West Angelas Petroleum Pipeline (WAPPL) is part of the overall Rio Tinto (RTIO) Power System Upgrade 330 (PSU330) Project that includes the development of new power generation and transmission infrastructure throughout the Pilbara Region of Western Australia to support RTIO’s iron ore production expansion to 333 Mtpa.

OSD, in partnership with KT Pty Ltd, completed the EPC of the WAPPL including 85km of DN350 gas transmission line and associated facilities. Scope included pipeline project management, design, construct, procurement, safety and operating plans, commissioning and ongoing operations and maintenance of the asset.

On behalf of the Company, I wish to extend my congratulations on a job well done. This is exemplified by the KT-OSD Joint Ventures’ excellent safety and environmental performance during the construction and commissioning through to the support of the challenging WAPS scope. The project was delivered in a collaborative and diligent manner. The JV did what you said you were going to do in delivering a project for Rio Tinto and this was demonstrated by the success of the pipeline project.
