Windward Hamburg is the fourth vessel in a VARD-built commissioning service operation vessel (CSOV) series, joining three sisters to strengthen Windward Offshore’s fleet for construction, commissioning and long-term O&M of offshore wind projects.
Windward Hamburg is the fourth VARD-built CSOV in Windward Offshore’s newbuilding series, joining Windward Athens, Windward Paris and Windward Munich.
The vessel is based on the VARD 4 19 design, measures 87.5 m by 19.5 m, accommodates up to 120 people and includes a helideck for added transfer flexibility.
Windward Athens and Windward Paris have already safely transferred more than 14,000 people using their motion-compensated gangways.
# Delivery and fleet context Windward Offshore has taken delivery of Windward Hamburg, the fourth commissioning service operation vessel (CSOV) in its newbuilding series with VARD. The four vessels in the series are Windward Athens, Windward Paris, Windward Munich and Windward Hamburg. Together they form the operational backbone of Windward Offshore's fleet for construction, commissioning and long-term operations and maintenance work on offshore wind projects.
# Vessel design and dimensions Windward Hamburg is based on the VARD 4 19 platform. The vessel measures 87.5 metres in length and 19.5 metres in beam. Accommodation is provided for up to 120 people. Like Windward Munich, Windward Hamburg is fitted with a helideck, giving project planners and crews an extra option for personnel transfer when required.
# Operational and technical features The CSOV combines features intended to support efficient and lower-emission operations. Notable technical elements described for the series are:
These systems are consistent across the sister vessels and are designed to increase operational flexibility and safety during offshore wind operations.
# Commercial status and early operations Windward Athens and Windward Paris are already operating for clients and have together completed more than 14,000 safe personnel transfers via their motion-compensated gangways. Windward Munich, delivered in July, was en route to Hamburg for an official naming ceremony and then scheduled to commence its first charter. Windward Hamburg joins the series as the latest unit to be delivered and is intended to enter operational service alongside its sisters.
Windward Offshore's managing director, Bastian Hagebeuker, described the delivery as a milestone for the newbuilding programme and credited close cooperation with VARD and equipment suppliers for achieving the fleet build-out. VARD's senior vice president sales, Runar Vågnes, said the vessels translate years of operational experience into purpose-built CSOVs based on the proven VARD 4 19 platform, and highlighted that all four ships were delivered on or ahead of schedule.
# Practical implications for projects
# What to watch next With the full four-vessel series delivered and entering service, the practical test will be their use across live projects: how often helideck operations are used, fuel mix and hybrid operation profiles, and transfer availability across different sea states. Windward Munich's imminent naming ceremony and first charter will mark the start of commercial deployment for that unit, while Windward Hamburg's operational schedule will determine how quickly the quartet is absorbed into ongoing offshore wind programmes.
