The Liwan Area is in a remote location offshore China, in 1,500 m water depth and approximately 300 km south of Hong Kong/Victoria. The Liwan 3-1 Area comprises the Pearl River Mouth Basin Contract Area 29/26 and nearby prospects. The Liwan gas field was discovered by Husky Oil China Ltd. (HOCL a subsidiary of Husky Energy) in 2006 through the drilling of well Liwan 3-1-1. In conjunction with this exploration well HOCL has performed extensive seismic surveys over an area of more than 3,000 km2 resulting in several other nearby prospects being identified.

This FEED project was executed using an Integrated Project Team (IPT) approach. The IPT comprising of HOCL, CNOOC and WorleyParsons / INTECSEA personnel was known as the Liwan Project Team (LPT).

Liwan 3-1 FEED scope was organized by sub-dividing the project into five work packages with workshare by various offices across the globe:

  • Work Package 1 (Perth Office): Subsea Tieback (SSTB)
  • Work Package 2 (Houston Office): Hull, Moorings and Risers (HM&R)
  • Work Package 3 (Ranhill WorleyParsons, Kuala Lumpur Office): Offshore Facilities (SWH)
  • Work Package 4 (INTECSEA Kuala Lumpur): Pipelines (DWPL/SWPL/DSPL)
  • Work Package 5 (Beijing): Onshore Facilities (OSGP)

Project Highlights

Work completed on time and on budget working across seven WorleyParsons/ INTECSEA entities in five countries on three continents across 14 time zones.
