Jasmund Substation Nears Baltic Sea Installation After Topside and Jacket Load-Out

; which holds the full EPCIC scope covering engineering, procurement, construction, installation and commissioning. OSS Jasmund is the first of three offshore substations the consortium is delivering for 50Hertz.Once operational, the Jasmund substation will have a capacity of 300 MW, supplying renewable electricity to around 260,000 households. It will serve as the grid connection point for the Windanker offshore wind farm, located northeast of Germany’s island of Rügen.Earlier this year, the HSI joint venture completed the rollout of the topside and lifted transformers at the Stormpolder

NKT Completes Export Cable Repair at Beatrice Offshore Wind Farm

to NKT, which was hired for the repair job following an unplanned transmission outage that occurred in April 2025 on one of two of Beatrice’s Transmission Capital Partner (TCP) owned export cables.The malfunction reduced the site’s export capacity by 50%, affecting the transmission of renewable electricity for around 450,000 U.K. households.The cable, which was not manufactured by NKT, was repaired using NKT’s adaptive rigid sea joint (ARSJ). Central to the swift turnkey repair were two of those joints, which were mobilized from NKT’s stock within days.The joints are designed to

Red Sea Cable Cuts Emphasize Infrastructure Resilience

, and economies feel the shock immediately. This sector is now more critical than ever to global security and stability.”Subsea cables carry 99 per cent of the world’s internet traffic and support $50 trillion in annual financial transactions. They also carry growing volumes of renewable electricity through offshore interconnectors. Disruption in one region quickly ripples through global systems, affecting communications, markets, and energy flows."The world depends on the marine contracting sector to repair these lifelines. But ensuring resilience is not automatic," added
