Facilitating floating wind industrialization
The Enhydra FWIV is designed to facilitate the commercialization of floating wind farms. This specialized vessel is designed to perform the full range of subsea construction tasks associated with floating wind farms safely and effectively in challenging environments and deep waters.
Inspired by the sea otter's physical and behavioral characteristics, the vessel’s unique design features make it highly adaptable to its environment. The FWIV can support a wide range of operations during the installation phases of floating offshore wind, including the mooring, hookup, and deployment of dynamic cables. This versatility makes for an efficient solution for the challenges of floating offshore wind.
Key to developing commercial scale floating wind is the industrialization of the process. This needs repeatability of operations and efficient logistics due to the sheer number of installations to be performed. This is where the Enhydra FWIV distinguishes itself.
An engineered platform for installing floating wind farms
The Enhydra FWIV is specifically designed as an installation and hookup vessel for floating wind turbines. A robust 400-ton main crane featuring NOV's proven AHC knuckle boom design boasts integrated heave compensation in a fully electric and closed-loop hydraulic setup, eliminating the need for a separate motion-compensated crane.
The versatile vessel is also designed for dynamic power cable deployment in various water depths, including vertical, horizontal, and inclined lay systems. Additionally, it seamlessly integrates the required buoyancy modules, ensuring safe and efficient deployment through automated “hands-free” processes.
Mooring installation
Choosing the right mooring system is crucial for floating wind foundations, considering factors like the environment, water depth, and foundation type.
We offer unmatched versatility, accommodating all mooring systems and their essential installation equipment, from pile templates to winch packages and ROVs.
Modular flexibility
Floating wind farm installations are diverse, each demanding a unique approach tailored to its geographic and environmental conditions.
The Enhydra FWIV's modular design empowers these projects with flexible mission equipment packages. Pre-engineered multiple deck layouts enable rapid integration, ensuring efficiency and versatility.
Dynamic cable
Capability to install dynamic cable is a crucial capability for any floating offshore wind farm. This capability is adaptable to varying water depths and environmental conditions and will need installation equipment and techniques to match.
The dynamic cable installation system's versatility, with horizontal, vertical, or inclined lay options, meets the unique needs of diverse project environments, ensuring efficient installation and hookup processes.
Collaborative effort
This FWIV results from collaborations spanning NOV's Marine and Construction business unit and with offshore wind farm operators, EPIC contractors, and specialist OEMs.
The GustoMSC™ vessel design offers a flexible deck layout for mission equipment integration, including electric subsea cranes from our Lifting and Handling group and Remacut™ cable-lay systems. The Multilayer Active Heave Compensation enhances safety, and the PowerBlade™ energy recovery system reduces emissions.
NOV's global resources and aftermarket services provide continuous support throughout the vessel's lifespan.
