A pioneering
feeder installation solution
The Maersk Wind Installation Vessel (WIV) is due for delivery in Q1 2026, having recently successfully completed her sea trials.
How our new feeder solution can optimise your project
Installing, not sailing
Our first-of-its-kind WIV remains on location to carry out uninterrupted installations, while feeder vessels ferry the turbines out to site
Absolute stability
Our patented stabilising technology enables a safe, secure and efficient WTG component transfer at sea – even in high sea states
Enabling more ports
The feeder vessels enable broader port access, from smaller, shallower marshalling points to ports behind bridges, locks or hurricane gates
Jones Act compliant
Our purpose-built feeder vessels are U.S. constructed, owned and operated, enabling us to operate effectively and efficiently in U.S. waters
The Maersk feeder solution explained…
Customised feeders
A purpose-built feeder spread of ATBs (Articulated Tugs and Barges) collects turbine components from port and ferries them to site.
Stable transfer at sea
The ATBs dock and lock securely onto the WIV, enabling a fixed-to-fixed component lift from feeder to WIV, rather than with a floating crane and barge.
Continuous installations
The Maersk WIV can therefore stay on location to receive components and carry out continuous installations.
Engineered for high-efficiency turbine installation:
how does our feeder-stabilising technology work?
- 1
The feeder spread docks at the Maersk WIV – and can do so in up to 2.5m waves (Hs).
- 2
The locking system engages, ‘pushing down’ the barge into the water to fully stabilise it.
- 3
Once fixed in place, the cargo frame is elevated to the WIV deck for load out of the turbine components.
- 4The locking system retracts, releasing the feeder vessel.
- 5
The tower, nacelle and blades are assembled by crane. The Maersk WIV remains permanently stationed at the windfarm carrying out uninterrupted installations.
U.S. Jones Act compliance
The Maersk feeder installation spread can operate anywhere in the world – including in the U.S.
This is because Maersk Offshore Wind has partnered with Edison Chouest Offshore for the construction of the purpose-built windfarm feeder spread, specifically designed for high-efficiency pairing with the Maersk Wind Installation Vessel.
This custom-built feeder spread includes two sets of Articulated Tugs and Barges (ATBs). Currently under construction by Bollinger Shipyards, both tugs and both barges with be U.S.-flagged, and owned and operated by Edison Chouest.
