Mainprize Offshore’s First-In-Class WFSSV Line-Up in Denmark


Mainprize Offshore, the world-renown builder, owner and global operator of wind farm service and support vessels (WFSSVs), has showcased three of its fleet of ground-breaking vessels in a line-up in the port of Esbjerg in Jutland, Denmark.

The three vessels are part of the Mainprize Offshore fleet of nine craft, all of which service the offshore sector, primarily focusing on the renewables and wind farm sector whilst also undertaking surveying, diving and other operations for its worldwide client base.

The Scarborough headquartered business launched its new build wind farm vessel, the MO5 in September, which boasts numerous first-in-class achievements.

The MO5’s equally innovative sisterships, the MO1 and MO3, both built by Mainprize Offshore are currently operating from the Jutland region, providing crew and cargo support to offshore wind turbines.

The MO1 was the first Mainprize Offshore vessel built by the company and specifically designed to meet the ever increasing current and future demands of the offshore sector. The design of the vessel which has a wave piercing bow on a hydrofoil dynamic and multi-chined hull provides unique lift and drag reduction, cruising at 23 knots at a modest 14litres per mile.

Her twin Caterpillar C32 engines and bow thrusters together with four-point anchor systems also enables it to deliver exceptional station keeping. Four 20ft containers can be carried aft with over 100m2 deck space, provides extensive deck area fore and aft, for both wind farm support and dive operations, together with two crane mounting points.

The MO1 is also ideal for geo-surveying, features a 1.5m2 moonpool and the extensive bridge which features an extended computer area enabling up to five people can monitor the survey activity with ease. The bridge’s capabilities include bathymetric, sidescan sonar, 2D seismic and magnetometer surveys, bottom and sub-bottom profiling and AUV/ROV survey work.

The MO3 is similarly designed to match that of the MO1, with her capabilities including drop core, grab sampling, water sampling, trawl survey, depth of burial, object location-and-recovery and route surveys, plus scour monitoring, intertidal and bird surveys.
