Woodside has welcomed the Australian Government’s final decision to grant environmental approval for the North West Shelf Project extension.
The operator’s Executive Vice President and Chief Operating Officer Australia, Liz Westcott, said, “This final approval provides certainty for the ongoing operation of the North West Shelf Project, so it can continue to provide reliable energy supplies as it has for more than 40 years.
The Australian Government approval includes conditions that require additional monitoring and management of air emissions to protect the Dampier Archipelago National Heritage Place.
Thus far, the North West Shelf Project has supplied more than 6,000 petajoules of domestic gas, powering homes and industry in western Australia. If used just for household electricity, this is enough to power homes in a city the size of Perth for 175 years.
Heavy lifting giant Sarens has outlined its role in the dismantling of the South Angsi Alpha offshore platform in Malaysia.
The dismantled platform, weighing around 4,000 tons, is the largest ever dismantled and reused in Malaysia, with part of its structure already located on the seabed, where it will serve as a support for the creation of artificial reefs.
Sarens, working on behalf of Marine Masters, used 16 units of 450/650 ton strand jack combinations to lower the Mobile Offshore Application Barge (MOAB) onto the barge on which the topside was loaded, in what is now the first task of this type carried out by the group’s Asia Pacific (APAC) team.
This was the first time Sarens APAC had worked on a decommissioning task using a strand jack solution, the company noted in a statement, so a significant amount of preliminary study was required to meet all the necessary requirements to meet the safety standards of the process, while ensuring that no downtime occurred.
Located in Block PM 305, approximately130 km from Terengganu, off the coast of West Malaysia, the South Angsi Alpha platform was in service from August 2005 until its closure in September 2019.
The floating storage and offloading vessel was decommissioned almost a year later, in March 2020, while the two-phase wells plugging and abandonment campaign was completed in August 2022.
“Once the main platform had been lowered, the topside, the 13 conductors and their four support legs were separated,” the Sarens statement noted.
“The topside was transported to the coast at the Labuan Shipyard, where the loose elements were unloaded.”
The platform's substructure was then sunk to the seabed, at a depth of approximately 70 metres, where it will now serve as a structure for the creation of artificial reefs.
Petrofac has secured an extension to its contract with ONEgas West, reinforcing its presence in the Southern North Sea market.
The deal, issued on 15 September 2025, continues Petrofac’s long-running service role across ONEgas West’s portfolio, including support for the Clipper South complex, Leman Alpha assets, Bacton Terminal, and OneGas barge operations.
John Pearson, chief operating officer of Petrofac’s Asset Solutions and Energy Transition Projects, noted that the company has supported these assets since 2020, positioning it as an embedded member of the delivery team with the ability to assist in production enhancement and field life extension.
This extension builds on a similar EPC contract awarded in March 2024, when Petrofac won a two-year brownfield EPC extension with ONEgas West, which is operated by NAM and owned by Shell UK. The renewed scope underscores ONEgas West’s confidence in Petrofac’s teams in Great Yarmouth and Aberdeen, valued for their operational knowledge and delivery.
As the industry faces pressures including energy transition goals and tighter regulation, contracts like this become strategic. Supporting key infrastructure such as terminals, complex offshore installations, and barge operations helps ensure continuity of supply and contributes to operational resilience.
For Petrofac, this deal strengthens its standing in one of its primary markets and demonstrates its capability to deliver both maintenance and enhancement in challenging offshore settings.
“Having supported these assets since 2020, Petrofac is embedded within the delivery team and is uniquely placed to support production enhancement and field life extension,” said Pearson.
“The North Sea remains one of Asset Solutions’ core markets and this award demonstrates confidence held in our team and the value they drive. We look forward to continuing this relationship, delivering safe and reliable operations.”
UK's Serica Energy has revised its 2025 production guidance following maintenance challenges and scheduled subsea work on fields tied to the Triton FPSO.
The Triton Floating Production Storage and Offloading (FPSO) vessel is operated by South Korea's Dana Petroleum.
Serica Energy said production guidance has been reduced to between 29,000 and 32,000 barrels of oil equivalent per day (boepd), down from a previous range of 33,000–35,000 boepd.
Operator Dana Petroleum notified Serica of a temporary reduction in output from the Triton FPSO due to a vibration issue within the compression trains.
Production is currently running at a significantly reduced rate but is expected to return to normal levels by the end of September once repairs are completed.
Production net to Serica from the Triton FPSO exceeded 25,000 boepd in August. Once both compressors are operational, output will be boosted further, supported by additional production from the EV02 well on the Evelyn field.
Dana has also scheduled subsea intervention work on the Bittern field for November 2025 to address an emerging infrastructure vulnerability.
Originally expected in 2026, the three-week scope will now halt production not only from Bittern but also from the Evelyn and Gannet fields, temporarily reducing Serica’s output by more than 20,000 boepd.
Despite the setbacks, Serica highlighted that production ramp-ups earlier this year had lifted wider portfolio output to more than 55,000 boepd in mid-August, before the maintenance-related constraints began.
DOF Group, a Norwegian vessel owner, has secured a new contract in the Asia Pacific (APAC) region for mooring hook-up services.
The contract scope includes DOF’s complete suite of in-house services, such as project management, engineering, procurement, and logistics support. For this project, the Skandi Hercules, a 109.6-meter vessel, will be utilised for mooring and subsea installation services.
Offshore execution is scheduled for the first quarter of 2026, with an estimated vessel utilisation of around four weeks. The total contract value is capped at $15 million, which DOF classifies as a smaller-sized contract.
The Skandi Hercules had previously provided similar services offshore West Australia. In addition to this contract, DOF Group recently announced a long-term commitment in the APAC region. This commitment involves a construction support vessel (CSV) for subsea construction, inspection, repair, and maintenance (IRM), as well as remotely operated vehicle (ROV) services for depths of up to 3,000 metres. The contract, awarded by an international operator, is set to commence in January 2026 for a one-year duration, with options for further extensions.
This new contract reinforces DOF’s growing presence and capabilities in the APAC market.

Reflecting a rise in confidence in Thailand’s offshore drilling and interventions expertise, as well as its keenness to embrace new technologies, PTT Exploration and Production Public Company Limited (PTTEP) has confirmed that it plans to go ahead with the nation’s first Carbon Capture and Storage Project (CCS) project.
It has reached a final investment decision (FID) on a US$320mn CCS project at the Arthit gas field, paving the way for the technology to play a role in advancing the country’s net zero goal.
The Arthit oil and gas field is an established producing field located in the Gulf of Thailand.
The CCS project will be designed to capture and store up to one million tonnes of carbon dioxide per year, said Montri Rawanchaikul, PTTEP’s CEO, and turns a “vision” into reality.
“PTTEP strives not only to safeguard the country’s energy security but also to reduce greenhouse gas (GHG) emissions,” said Rawanchaikul.
“CCS is an essential technology, both nationally and globally, complementing other clean energy solutions in addressing climate change.”
It marks a strategic step toward applying the technology to reduce GHG emissions, in line with government policy, which recognises the project under the Nationally Determined Contribution (NDC) Action Plan on Mitigation 2021–2030.
“The Arthit CCS Project will serve as a pilot for cultivating expertise and driving CCS adoption in Thailand, including the Eastern CCS Hub in the Northern Gulf of Thailand, which has potential to make material contribution to the country’s net zero target and enhance the nation’s long-term economic competitiveness” added Rawanchaikul.
CCS is regarded as a reverse process of petroleum exploration and production.As natural gas is extracted from underground to provide energy for national development and everyday life, the excess carbon dioxide is captured and safely injected back into its original subsurface reservoirs.
A huge amount of preliminary work has already gone into the Arthit CCS project, from storage site selection with reservoirs at depths of 1,000–2,000 metres, to engineering design, and comprehensive Measurement, Monitoring and Verification (MMV) programmes.
PTTEP intends to leverage existing infrastructure at the field while constructing and installing additional facilities as required.
It hopes that carbon storage operations will commence in 2028, with capacity gradually ramping up to around 1 million tonnes of carbon dioxide per year.

Starting tomorrow, we are moving forward even more decisively, faster, unlocking our country's potential for progress and prosperity for all Greek women and men."
Well integrity specialist Unity has strengthened its capabilities in the Asia Pacific (APAC) region after securing a new partnership with Clear Cut Interventions (CCI) Australia, a leading provider of well intervention services.
The collaboration marks a significant step forward in delivering advanced intervention and well integrity solutions to operators across Australia and also shoring up service and support across the wider APAC region.
“The partnership…reinforces Unity’s long-term commitment to the Asia Pacific region, establishing Perth as its regional hub, and providing a platform for further international growth,” Unity announced in a statement.
“At the same time, it enhances CCI’s already comprehensive suite of end-to-end solutions across the well lifecycle."
Through this partnership, operators will now benefit from the local deployment of Unity’s proprietary Compact Intervention Suite of Tooling, QV range of Wellhead & Christmas Tree products and Thru Tubing solutions, supported by CCI’s established infrastructure, the company noted.
The collaboration also ensures rapid mobilisation and operational assurance without the need to import support from overseas, it added.
CCI is an Australia-based oilfield services provider specialising in Hydraulic Workover (HWO), slickline/wireline, coiled tubing, and onshore drilling services.
“Together we are creating something unique for local operators: the assurance of world-class technology delivered with the speed, agility, and regulatory confidence of an established Australian partner,” said Stuart Slater, Unity’s Technical Sales Director.
By addressing the offshore realities of limited POB, restricted deck space and crane capacity, the partnership will also ensure operators can execute critical well integrity work with greater efficiency, safety and certainty, the statement added.
Limited POB well intervention refers to performing maintenance or restoration on an oil or gas well, but with a restricted number of personnel on-site, often due to platform limitations, safety concerns, or cost-saving measures.
“POB limits, tight decks and de-rated cranes can turn simple interventions into major logistics exercises,” said Dean McTiffen, Managing Director, CCI.
“With Unity’s compact tooling in-country and CCI’s Western Australian team and infrastructure behind it, we’re giving operators a genuinely end-to-end route to safer, faster interventions that fit the real-world constraints offshore.”
