Apache PVG Pty Ltd, on behalf of the Coniston-Van Gogh Production Joint Venture titleholders (Apache PVG Pty Ltd [52.501% ownership] and Inpex Alpha Ltd [47.499% ownership]) recovers oil in production licence area WA-35-L using the Ningaloo Vision floating production, storage and offloading (FPSO) vessel (Figure 1-1). Oil recovered from the Van Gogh, Coniston and Novara fields via the subsea infrastructure will be processed and stored on board the Ningaloo Vision topside facilities for loading and export. Oil has been recovered from the Van Gogh field using the Ningaloo Vision FPSO since 2009. Following additional subsea installation and FPSO rectification works, production re-commenced in Quarter 2 2015, allowing oil to be recovered from the additional Coniston and Novara fields. The estimated operational life of the Van Gogh, Coniston and Novara fields is 15 to 20 years.
The FPSO and subsea infrastructure are located within Production Licence WA-35-L in Commonwealth waters, 45 km north-northwest off the Cape Range Peninsula in Western Australia. The FPSO is located 53 km north-northwest of the Exmouth township and 29 km from the northern boundary of Ningaloo Marine Park (Figure 1-1). The development occurs in water depths ranging from 340 m in the east of the production licence to 400 m depth in the west, with the FPSO moored in a water depth of 341 m. The EP covers all activities within a 500 m buffer, termed the Operational Area, around the FPSO and subsea infrastructure (Figure 1-1). The proximity of the development area to other key coastal or mainland features is:
State/Commonwealth waters boundary – 30 km southeast.
Ningaloo Marine Park boundary – 30 km southeast.
Muiron Islands Marine Management Area – 35 km southeast.
Ningaloo Reef proper – 45 km south.
North West Cape – 45 km south.
Barrow Island – 140 km northeast.
Oil from the Van Gogh, Coniston and Novara fields will be recovered via subsea production wells and equipment which direct the production liquids to the FPSO for processing and storage. As part of production, produced water and excess gas produced (excludes gas required for fuel and gas lift) are reinjected, and offtake tankers load the recovered oil from the FPSO on a regular basis. If the re-injection of PFW to the reservoir is not possible due to the injection system being partly or wholly unavailable, PFW will be discharged to the marine environment as a contingency event. Support vessels provide logistical support for loading of supplies, offloading of wastes, oil spill response and carrying out maintenance and inspection activities. Helicopters are used for transport of personnel to and from the facility.
A number of vessel based support activities (VBSA) are undertaken from time to time to ensure the efficient day-to-day operation of the Ningaloo Vision FPSO. This includes logistical support for loading of supplies, offloading of wastes, oil spill response and carrying out maintenance and inspection activities. The vessels used for these activities depend on the specific requirements of the proposed activity, the water depth and the availability of vessels. The vessels are vetted by Apache to ensure appropriateness for the required activities. Most of the vessels are typically locally sourced from the northwest shelf region.
