The NOV-designed Modular Service and Operations Vessel (MSOV) is a novel and versatile concept to optimise offshore wind farm operations and maintenance. The vessel has been designed with wind farms further offshore and in deeper waters in mind.
These types of wind farms require robust operations and maintenance strategies. Support vessels must be able to operate safely, effectively, and longer in increasingly challenging environments.
The MSOV concept is a collaboration across NOV‘s Marine and Construction business unit. To introduce the concept, an MSOV design was developed based on GustoMSC’s Enhydra MSOV design. The vessel design offers an extensive and flexible deck layout to integrate mission equipment from NOV’s Lifting and Handling group and Remacut to maximise capability, workability and endurance.
The Enhydra series design characteristics resemble 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.
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. Featuring Remacut cable-lay equipment, this versatile workhorse is designed for cable repair and change-out, subsea inspection and intervention, and mooring installation for floating wind farms.
The Enhydra MSOV will allow wind operators to use the modular capabilities to manage even unplanned operations. The increased workability and versatility of the Enhydra MSOV is to provide a cost-effective year-round working platform covering the life cycle of the wind farm.
