NOV has unveiled an offshore wind farm service vessel concept designed for working at sites further from shore in deeper waters.
The Modular Service and Operations Vessel (MSOV) aims to optimise offshore wind farm operations and maintenance and is the result of collaboration across NOV’s Marine and Construction business unit.
The MSOV design was developed based on GustoMSC’s Enhydra MSOV design to provide an extensive and flexible deck layout to integrate lifting and handling equipment.
At 140 metres in length, the Enhydra MSOV’s larger design allows for additional capabilities by integrating additional modular equipment, increased comfort, and capabilities beyond current construction/service operations vessels.
It also features NOV’s Remacut cable-lay equipment, used for cable repair and change-out, subsea inspection and intervention, and mooring installation for floating wind farms.
The Enhydra series design characteristics mimics the sea otter’s (Enhydra) unique and physical behavioural features.
The sea otter is the sole marine mammal to use tools and it uses its streamlined body design to efficiently perform deep dives to the seafloor and adapt its lung capacity to float effectively on the surface.
The Enhydra MSOV will allow wind operators to use the modular capabilities to manage even unplanned operations and provides a cost-effective year-round working platform covering the life cycle of an offshore wind farm.
