signaling the end of the subsea construction phase and the successful construction of the OAL within a short timeframe."This means that the ambitious goal of enabling gas feed-ins into this pipeline in the winter of 2023/24 has been achieved. This is the contribution we can make as a transmission system operator to improving German and European security of supply and its resilience to crises. Despite a very ambitious schedule, we managed to complete the OAL in record time," said Ulrich Benterbusch, Managing Director of GASCADE.Day-to-day management of the project was coordinated by ABL&rsquo
