Esso Australia bolsters fleet of mobile offshore assets
Esso Australia, a subsidiary of ExxonMobil and operator of the Gippsland Basin joint venture, has signed an agreement to charter the Helix Q7000 semisubmersible vessel to support decommissioning activities in the Gippsland basin from the end of the year, ExxonMobil said on January 20.
“The Helix Q7000 is a welcome addition to our extensive fleet of vessels and rigs currently operating across the Gippsland Basin,” ExxonMobil Australia Chair, Dylan Pugh, said.
“It is the fourth mobile offshore asset we have added to our decommissioning fleet, and marks the first time we will be using a light well intervention vessel for subsea work locally,” he added.
Rig 22 is currently executing a plug and abandonment campaign at Flounder, whilst the HWT600 rig is finalising plug and abandonment activities at Fortescue before it moves onto its next campaign at Bream. The multi-purpose support vessel has completed a marine life survey utilising its remote operated vehicle equipment, which will be followed by decommissioning activities at Perch and Dolphin monotowers this year.
“We are committed to sourcing the right assets for the work we are completing, given the variety of fields we have operated for over 50 years. Our priority is to remain safe, whilst using fit for purpose solutions which ensure we are meeting our decommissioning requirements,” Pugh concluded.
