Security Concerns Drive Interest in Subsea Clamps
Special to P&GJ
Increased concerns about energy security and the desire to support net-zero targets through innovative decommissioning projects are driving up demand for subsea clamps and connectors, according to pipeline technology specialist STATS Group.
The global demand for energy, set against a backdrop of political uncertainty and instability, means protecting and maintaining the integrity of pipeline networks cannot be overstated.
STATS responded to client concerns by producing the SureConnect standardized range of mechanical connectors and clamps, which allows operators and contractors to carry out planned maintenance or respond quickly to emergency scenarios.
Recently the technology has been installed at a pipeline flange repair site in the U.K., North Sea. Additionally, an 18-inch hot-tap clamp was used to enable a pipeline tie-in in the Bass Strait, off the coast of Australia, as well as at a new gas-lift line running to an existing pipeline in the Norwegian Continental Shelf.
“Typically, the industry does not hold significant stock of large-diameter/high pressure connectors or repair clamps,” said Andy Norrie, STATS group head of Business Development, Europe. “With lead times sitting at around 16 weeks-plus, it makes sense to put in place contingencies should an asset be compromised and production is threatened.”
Within the standardized product range, there is flexibility to adapt subsea connectors to suit specific client requirements, including design codes, pressures, materials and flange requirements.
“Any interruption to the flow of oil and gas through the international pipeline network can have significant impact on the energy supplies for millions of people and can result in the suspension of industrial activities,” Norrie said. “It is therefore essential that in the event of an issue, repairs can be implemented quickly and safely with the best possible technology solutions to restore their operation and ultimately energy supply.”
ABL Completes German Subsea Pipeline Installation Project
Energy consultancy ABL finalized its marine warranty survey (MWS) scope in connection with the installation of Germany’s (OAL) subsea pipeline, with the first gas feed-in expected shortly.
ABL was contracted by Gascade Gastransport GmbH (GASCADE) to the MWS services and oversee the transportation and installation operations, concerning the 48-inch, 31-mile (50-km) subsea pipeline.
The pipeline will connect the planned LNG terminal in the port of Mukran with the German pipeline network in Lubmin. In the future, the pipeline will also be used to feed green hydrogen into the German grid via the Mukran entry point.
“OAL is an important energy infrastructure project which strengthens the security of gas supply in Germany and across Europe,” said Sergio Leone, ABL’s MWS tender and project manager for the OAL pipeline project.
The above water tie-in was recently completed, signaling the end of the subsea construction within a short timeframe.
Day-to-day management of the project was coordinated by ABL’s team in Germany, based in Hamburg. Onsite attendances were supported by ABL’s wider European network, to ensure operations are resourced with local technical expertise where possible, including using consultants from ABL Germany, Holland, Norway and France.
“Despite a very ambitious schedule, we managed to complete the OAL in record time,” said Ulrich Benterbusch, managing director of Gascade. P&GJ
