+-------------------------------------------------------------------------+Dimensions and Accommodation
Measuring 87.5 meters in length and 19.5 meters in width, the vessel offers an optimal balance between hydrodynamic stability and maneuverability. The hull form is engineered to minimize motion in rough seas, directly improving technician comfort and reducing the risk of motion sickness—a critical factor in maintaining workforce productivity on long offshore rotations.
The vessel can accommodate up to 120 personnel in high-standard, low-noise cabins. It features state-of-the-art recreational spaces, modern dining facilities, and dedicated offices and workshops for wind turbine technicians. This ensures that the vessel serves as a highly functional, comfortable "home away from home" during extended offshore campaigns.
Advanced Access and Lifting Systems
The primary functional interface of any CSOV is its "Walk-to-Work" (W2W) system. The Windward Hamburg features a height-adjustable, motion-compensated gangway with an integrated elevator. This system actively counteracts the pitch, roll, and heave of the vessel, allowing technicians to walk safely from the ship directly to the transition piece of a wind turbine generator (WTG) or substation, even in significant wave heights.
Complementing the gangway is a state-of-the-art, 3D motion-compensated electric crane. Unlike traditional hydraulic cranes, electric cranes offer superior energy efficiency, precise control, and a reduced risk of hydraulic fluid leaks, aligning with the clean-energy ethos of the offshore wind sector. Additionally, the vessel is equipped with a height-adjustable boat landing system, providing safe boarding options for Crew Transfer Vessels (CTVs).
Multi-Modal Logistics: The Helideck Integration
Like its sister ship, the Windward Munich, the Windward Hamburg features a fully certified helideck. This feature provides wind farm operators with maximum logistical flexibility. While the motion-compensated gangway remains the primary method for bulk technician transfers, the helideck enables rapid emergency medical evacuations (Medevac), swift transfers of specialized technicians, and the delivery of critical spare parts without interrupting the vessel’s primary marine operations.
Decarbonized Propulsion: Prepared for Green Methanol
As the maritime industry faces tightening environmental regulations from the International Maritime Organization (IMO) and the European Union’s Emissions Trading System (EU ETS), future-proofing vessel propulsion is a commercial necessity.
The Windward Hamburg features an advanced battery-hybrid propulsion system designed to optimize engine load, reduce fuel consumption, and minimize greenhouse gas emissions. The onboard battery packs act as an energy buffer, providing peak-shaving capabilities during dynamic positioning (DP) operations and allowing for zero-emission port stays.
Importantly, the vessel’s propulsion architecture has been designed with a clear upgrade path for future operation on green methanol. This dual-fuel readiness ensures that as green methanol supply chains mature, Windward Offshore can transition the fleet to near-zero-carbon operations, offering wind farm developers a truly sustainable logistics chain.
