ABL Completes German Subsea Pipeline Installation Project

Special to P&GJ 

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.
