Offshore Energy Briefing: Black Sea FPU Fabrication Begins and Ecowende Cable Programme Completes

## Offshore Energy Briefing: Black Sea FPU Fabrication Begins and Ecowende Cable Programme Completes Two significant milestones in the offshore energy sector have been reported this week, spanning both hydrocarbon production infrastructure in the Black Sea and renewable energy development in the North Sea. ### Wison New Energies Kicks Off Black Sea FPU Topside Work China-based clean energy services provider Wison New Energies (WNE) has initiated topside fabrication for a floating production unit (FPU) destined for deployment at Türkiye's largest natural gas field in the Black Sea, according to Offshore Energy. The project represents a strategically important step in Türkiye's ambitions to develop its substantial offshore gas reserves, which are expected to play a central role in the country's long-term energy security strategy. The Sakarya gas field, discovered in 2020, holds an estimated 710 billion cubic metres of natural gas, making it one of the most significant hydrocarbon finds in the region in recent decades. WNE's involvement underscores the growing role of Chinese engineering and fabrication firms in major international offshore energy projects. Topside fabrication is a critical phase in FPU construction, encompassing the processing, utility, and accommodation modules that sit above the hull structure. Commencement of this work signals that the project is advancing toward its operational timeline. ### TKF Completes Final Cable Loadout for Ecowende Offshore Wind Farm In the North Sea, Dutch cable manufacturer TKF has successfully loaded out the final batch of inter-array cables for the Ecowende Hollandse Kust West offshore wind project, Offshore Energy reports. The completion of the cable loadout marks a key logistical milestone for the project, which forms part of the Netherlands' broader offshore wind expansion programme. Notably, TKF highlighted that the cable production and delivery were achieved with a reduced environmental footprint, reflecting the increasing industry focus on sustainable supply chain practices within the offshore wind sector. Inter-array cables are essential components connecting individual wind turbines within a farm to the offshore substation, and their timely delivery is critical to maintaining installation schedules. The Hollandse Kust West zone is one of several large-scale offshore wind areas being developed off the Dutch coast as the Netherlands works toward its renewable energy targets. ### Outlook Together, these developments reflect the breadth of activity across the offshore energy spectrum — from fossil fuel infrastructure supporting national energy security in emerging markets, to the continued build-out of European offshore wind capacity. Both projects highlight the international nature of the offshore supply chain, with specialist contractors and fabricators operating across borders to deliver complex marine energy infrastructure.
