Based on a proven workboat design concept, the CTruk EVOC22 is a 22m composite twin-hull with 7.5m beam and 1.25m draft. 

The workboat will have a 20 tonne flexible payload capability and the ability to carry 24,000 litres of fuel, an invaluable function in servicing round 3 zones. CTruk’s patented moveable wheelhouse and flexible deck pod system will allow the vessel to fulfil multiple roles; potentially transferring 12 technicians in comfort one day and removing its passenger pod to make use of 72m² of deck space for equipment transfer the next, carrying cranes, transfer systems and amphibious rescue vehicles such as the CTruk Avenger.

CTruk’s experience and dedication to incorporating client feedback is serving the company’s in-house design team well. New features on this vessel include a protected controllable pitch propeller (CPP) system which will give optimal bollard pull and service speeds, significantly increasing the renowned fuel efficiency of CTruk’s lighter weight composite catamarans and yet still allowing the boat to take the ground and dry out at low water. Various engine options are available and the inclusion of bow thrusters will give greater manoeuvrability.

Designed and built to Bureau Veritas (BV) classification rules, the vessel will join offshore wind solutions provider CWind’s charter fleet, where the increased capacity of this larger OWSV is eagerly awaited.

The first CTruk EVOC22 (EVOC stands for Efficient Versatile Offshore Catamaran) is currently in production at CTruk’s Essex yard and due for delivery in September 2014. Presented to the market with CWind’s proven service package and fleet management experience, she promises to be a game-changer for offshore wind construction, operations and maintenance further out to sea.
