SINGAPORE – Jadestone Energy has decided to change the offtake arrangements for its Stag oil field offshore northwest Australia.
Until now, the field’s oil, produced through a fixed-leg, central processing facility platform, has been offloaded to the FSO vessel Dampier Spirit, which is moored to a catenary anchor leg mooring buoy.
In May 2020, Altera Infrastructure advised Jadestone of its intention to retire the vessel and has not been able to provide a suitable replacement.
Jadestone has responded by contracting an international tanker provider to supply modern, double-hulled tankers for crude offtake from Stag.
The company claims this new approach will lessen the environmental risk by eliminating ship to ship oil transfers in field, also leading to annual savings of around 20% compared with the current arrangement.
The first offtake tanker should arrive at the field in mid-September, coinciding with the Dampier Spirit’s departure. Multiple offtake tankers will eventually come in on a rotating basis.
Jadestone has worked with Australia’s National Offshore Petroleum Safety and Environmental Management Authority and the Australian Maritime Safety Authority (AMSA) to ensure the new model complies with all relevant laws and regulations.
This includes an agreement that the vessels should be regulated by AMSA.
