Fastnet turns into the wind
Fastnet Tern is the latest in a long line of specialist commercial catamarans supplied by Blyth Workcats Ltd.
The Essex UK based builder has delivered Fastnet Tern, a Blyth 14m wind farm support vessel (WFSV)to Martin and Trevor O’Hanlon of Fastnet Shipping Ltd, which operates a variety of workboats and delivers a range of marine services from its base at Waterford in Ireland.
Fastnet Tern follows quickly on the heels of Fastnet Swift, launched at the end of last year. These two vessels mark the start of a considerable investment by Fastnet Shipping, with a requirement of further vessels already identified
These projects have benefitted from extensive collaboration between builder and client. Drawing upon many years experience in commercial vessel and plant supply and operation, Martin and Trevor O’Hanlon had identified a detailed list of requirements for these latest new vessels. With an eye on specification details which are now becoming industry standards, Blyth Workcats has been able to deliver in every respect whilst keeping compromise to an absolute minimum.
The Blyth 14m WFSV has a beam of 5m and draws only 1m. Key features of the vessel include a stylish and practical split level wheelhouse which gives the design the feel of a much larger vessel. A large forward deck area can both receive loads and provide for safe engineer transfer to wind farm turbine towers. There is excellent all round visibility for the helmsman and crew, which allows for safe manoeuvring and turbine docking activities. The practical and convenient helm consul layout ensures essential controls are all to hand and visual displays are comfortably positioned for fatigue free observation.
The large wheelhouse is insulated and lined, with hard wearing non-slip flooring and comfortable suspension seating for 12 engineers. There is also a separate helm/crew area with additional dinette seating and a folding table. A well equipped galley includes sink, hob, fridge and microwave, while a large separate on deck toilet/shower compartment benefits from pressurized hot and cold water. There is also a diesel warm air cabin and screen heating system.
Generous side decks are illuminated for enhanced safety when working at night and the large aft working deck features cargo tie down points, and engine hatches with service hatches inset. A 750mm by 750mm moon pool allows for the deployment of survey equipment. A guardrail protected observation area on the wheelhouse roof is reached by permanent access steps.
Under the deck there is reinforcement and a hydraulic system pre-installed and ready for the future fitting of a Bonfiglioli P 3500 L deck crane which will lift 990kg at 3.25m, extending to 260kg at 9.45m. Power is supplied by a6 KVA diesel generator and 3,500 kW inverter/charger.
Propulsive power is supplied by fuel efficient new Iveco C9 620hp engines commercially derated to 550hp at 2,530 rpm and driving Clements Engineering Super Duplex shafts and four blade high performance propellers through Twin Disc MG 5065A gearboxes with a ratio of 1.72:1 to deliver a creditable sprint speed of 27.5 knots.
The Iveco 8.7 litre engines feature the most up to date technology, including Electronic Common Rail (ECR) injection which improves fuel efficiency and reduces the impact on the environment. The fuel system has also been integrated under the tappet cover in order to allow all the high pressure ducts to be kept inside the engine for improvements in terms of safety.
A high specification Furuno based navigation and communications electronic system was supplied by Mantsbrite Marine Electronics.
This comprehensive list of ‘must haves’ has resulted in the Blyth 14m WFSV being a genuine multi-role workhorse, often described as the ‘entry level’ vessel in an increasingly competitive and selective market.
Fastnet Tern and Fastnet Swift have been built under the scrutiny of the Irish Department of Transport by independent survey to ensure full compliance with the construction and safety standards demanded of the Irish P5 passenger vessel operating certificate as well as MCA COP 12+2, 60 miles offshore.
Whilst taking such quality discipline in their stride, Blyth Workcats is committed to a policy of continuous improvement evidenced in 2010 with the award of ISO 9001:2008 accreditation. Ongoing discussion with DNV confirms the builder’s approved capability and willingness to offer clients the opportunity to have a letter of compliance issued by that organisation.
Blyth Workcats Ltd will be exhibiting at Seawork 2011 with a further example of the Blyth 14m as well as the Blyth 11m charter angling vessel Top Cat 111.
