Equinor, Partners Bolster Åsgard Production with Subsea Compressors Upgrade
came on stream in 2015.This was the world's first facility for gas compression on the seabed and the result of extensive technological development.The plans described that there would be a need for increased pressure in the long term to compensate for the pressure drop in the reservoirs. The first compressor module in phase two was replaced in 2023, now the second and final module has been installed, at a depth of 270 meters.With a total weight of 5100 tons, a footprint of 3300 m2 and towering 26 meters above the seabed, it is the largest subsea processing plant ever installed.The ÅSC station
Deepest-Ever Subsea Compression Systems Come Online Offshore Norway (Video)
Two SLB OneSubsea subsea compressor stations recently came online at Shell’s Ormen Lange field, the second largest gas field in Norway, setting the record for the deepest installation of such systems ever.The SLB OneSubsea subsea compressor stations, installed more than 900 meters below sea level in Norwegian Sea, represent the deepest subsea compression system ever deployed.Gas is transmitted 120 kilometres to Shell’s Nyhamna processing plant onshore, also marking the longest subsea ‘step-out’ in history.Shell said the technology will unlock an additional 30 to 50 billion

valves that fit on the low point of each tank. They had a garden hose fitting on the bottom, so we didn’t have to mess around looking for a special hose. We’d open each of these and drain what was left in the tanks into a wheeled 300-gallon tank.“Then we’d use a large compressor to blow air into the bottom of the tanks and out the top to evaporate the remainder of the gas. It took about 2 days for all the gas to evaporate. That was really the only dangerous part of putting the ‘scaphe back in stand-by mode. The air coming out of the compressor was
Subsea Compression: A Step Change at Ormen Lange
Director, OneSubsea Processing and Richard Crichton – Shell Project Director Ormen Lange Phase 3.“This project is unique. We’re providing essential gas to the UK and Europe via one of the lowest carbon-intensive projects in the world. To achieve this, we are installing a subsea compressor approximately 120 km from the onshore facility, and that’s never been done before. It’s a real step change and an enabler for the wider industry,” says Richard.“To include the deployment of late-life subsea compression in the original development plan for Ormen Lange was
Aker Solutions to Deliver Subsea Umbilical for Chevron's J-IC Project Off Australia
won a deal to deliver the dynamic subsea umbilicals for the offshore gas compression development.Under the contract, Aker Solutions will be responsible for the engineering, design, and manufacturing of a total of about 70 kilometers of dynamic subsea umbilicals. The scope of work includes three subsea compressor umbilicals, two subsea pump umbilicals, as well as ancillary equipment and spares. The umbilicals will provide power from the offshore platform to the subsea compressor and pump modules.Aker Solutions said the contract was a sizeable one, meaning it is worth NOK 200 million ($23,3 million) and
Aker Solutions Confirms Major Subsea Compression Contract with Chevron
of the all-electric subsea gas compression system. It also includes interface responsibility and assistance during installation and commissioning. Chevron Sanctions $4B Jansz-Io Compression Project Offshore AustraliaThe subsea gas compression system will include a compression station with three compressor modules and two subsea pump modules, all-electric control systems and actuators, structures including mud mats, a high-voltage electrical power distribution system, several spare modules and equipment, and various associated tooling.

ABB Wins UTC Award for Subsea Electrification Technology
, was one of the industry’s largest JIPs and, at peak, involved more than 200 scientists, engineers, and specialists from ABB.Following the completion of the JIP in 2020, the VSDs [variable speed drives] have undergone the world’s first full-scale string testing with a OneSubsea multiphase compressor WGC6000.The UTC Award, which recognizes, celebrates, and showcases outstanding achievements within the global subsea industry, was presented Thursday, during this year’s UTC event, to Svein Vatland, Vice President Subsea Technology Program, at ABB, who represented the ABB team that delivered
Putting Power on the Seabed: Edging towards a Subsea Powerhouse
TechnipFMC, while Baker Hughes’ Modular Compact Pump aims to come with integrated VSDs, mitigating the need for full-on ‘type-3’ (i.e. supply, transmission, and distribution).The goal is to provide power, ranging from 750 kW to more than 11MW, to subsea systems, from pumps to compressors.This includes the power equipment and electronics required, to avoid having to make brownfield modifications on existing topsides and/or enable entirely subsea developments to shore. The benefits are touted as a more scalable and flexible architecture.However, the much longer step-outs that have
Siemens Equipment for Large Gas Field Project Offshore Malaysia
Siemens Gas and Power has been awarded a contract to supply gas turbine generators, gas turbines and centrifugal compressors for the Petronas' Kasawari gas field development project offshore Sarawak in Malaysia. The order was made by Malaysia Marine and Heavy Engineering (MMHE) which has formed a joint venture with TechnipFMC to execute the work for Petronas.Siemens will supply three SGT-300 industrial gas turbine generators (GTG), three mechanical-drive SGT-300 gas turbines and three DATUM centrifugal compressors for the Kasawari project in the South China Sea.With an estimated recoverable
