OSD’s Role

  • Owners Engineer
  • Engineering (Concept, FEED, Detailed Design)
  • Construction Support


Australia Pacific LNG’s Main Pipeline System (MPS) and High Pressure Gas Network (HPGN), operated by Origin, supplies gas to the LNG export facility at Curtis Island in Gladstone, Queensland.

In early 2017, OSD transitioned from an Owners Engineer capacity to providing the Concept, Front-End and Detailed Design engineering services to Australia Pacific LNG.

The Globe Valve Bypass solution required OSD to design modifications to MPS and HPGN pipeline facilities to optimise de- and re-pressurisation times while maintaining process conditions within the safe operating envelope and controlling vibration within acceptable limits.

The project was unique in its requirement for extensive process simulations (Hysis) and the adoption of detailed assessments against specific vibration criteria. OSD together with Xodus/Wood (vibration consultants) provided multi-discipline engineering services to APLNG.

OSD delivered the final engineering works packages in late July 2018 and site installation works remain underway. OSD project scope extends to Construction Support and As-building.
