Beach Energy Limited, a subsidiary of Australia’s Beach Energy, has taken a significant step in its offshore operations by submitting a revised environment plan (EP) for subsea installation and commissioning activities off the coast of Australia. The plan outlines the replacement of a failed flowline and the connection of two new wells to the Otway Gas Plant, along with the recovery of the failed flowline for proper disposal.
The National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) confirmed the submission of the revised environment plan by Beach Energy in November 2023. The proposed activities are part of Phase 5 of the Otway Offshore Project, aimed at bringing two remaining wells online and ensuring efficient gas production.
Phase 5, initiated in February 2023, involved tying in four new wells in the Thylacine field to the Thylacine A gas production platform. While the commissioning of Thylacine North-1 and North-2 wells was successful, the connections for Thylacine West-1 and West-2 were delayed due to the failure of a flowline during pressure testing.
The revised EP, known as Phase 5b, addresses the completion of the remaining work, focusing on subsea installation and commissioning activities. These activities will involve the use of a construction support vessel (CSV) within the Otway Basin in Commonwealth waters. The planned location is approximately 65 km southwest of the Victorian coastline, with the installation and commissioning set to take place between the third quarter of 2024 and the fourth quarter of 2025.
Beach Energy’s commitment to advancing its offshore projects extends beyond the Otway Offshore Project. The company is poised to commence drilling operations off Taranaki toward the end of the first quarter of 2024, utilizing one of Valaris’ heavy-duty modern jack-up rigs.
As Beach Energy progresses with its growth projects, the broader Australian Energy Producers have urged regulatory improvements to address delays in project approvals. Regulatory uncertainty has led to extended waiting times for exploration and development projects, impacting the energy supply chain and carbon capture initiatives.
