Windcat 41 - "extreme smooth ride in rough seas"

25.04.2018

"Windcat 41" is the latest addition to the Windcat fleet. This is the 17th vessel in cooperation between Windcat Workboats and Servogear. "Windcat 41" is currently operating out of Barrow, UK, from where it will be performing operations and maintenance activities on the Ormonde offshore wind farm.

Windcat Workboats have launched their second vessel in their new MK3.5 series: “Windcat 41”. The new hull shape, which is the basis for this vessel type, shows radical improvements in performance, comfort and efficiency compared with the present vessel design. Being part of the industry’s LCOE (Levelized Cost of Energy) reduction goals. Windcat has put significant effort into developing cost effective vessels that fit to the ever-evolving demands for higher comfort and performance. However, the approach to make radical changes in the hull design for our new generation of vessels was a considerable risk.

The management team at Windcat had full confidence in the new vessel when the designer Pete Melvin presented the concept he developed that would reduce fuel consumption and give added comfort at high speeds. Thus, after extensive computer modelling the decision was made to invest in a new generation of Windcat vessel types known today as the Windcat MK3.5. Managing Director Neil Clarkson states: “The result has surpassed the design expectations. The hull shape of the vessel which has been optimised for efficiency, comfortable sea keeping and performance has resulted in a highly efficient 23 meter vessel, with a top speed of 31 knots using only two 720kW engines, setting a new industry standard for efficiency”. The result is high performance with low emissions and low fuel consumption, which creates cost savings for the end user.


The vessel is built according to the latest technologies, rules and regulations to create a state of the art vessel carrying 26 technicians. The vessel meets the highest standards to allow working on international projects. Neil Clarkson comments: “As the wind farm industry matures and is becoming less dependent on governmental support we feel that we have to play our part in reducing the operating costs for the charterer. At Windcat we believe that this should be achieved by reducing the fuel consumption as we are convinced that reducing costs on the crew, maintenance or safety is not the correct approach as this will result in a reduction of the level of service we aim to supply”.


Windcat Workboats is very pleased with the achieved performance levels on the Windcat 41, both in way of fuel consumption, 250 liters per hour at 25 knots and 360 liters per hour at 30 knots, as well as the extreme smooth ride in rough seas and the transfer capabilities. The result of the high performance and efficient hull shape together with our Windgrip transfer system we are looking at a reduction of fuel consumption and the associated CO2 NOX emissions of up to 40% on conventional designs commonly used in the industry at the moment. Neil Clarkson concludes: “You don’t have to be a great mathematician to calculate how much money can be saved over the 25 years operational life of a windfarm”.

Windcat currently has two vessels of this type, one is operating a windfarm in Germany and the latest addition the Windcat 41 is operating out of Barrow, UK where she will be performing O&M activities on the Ormonde Wind Farm. Windcat is building at least three more vessels of this type, with the Windcat 42 becoming available this summer.
