FINTRY Marine Ltd. designs and markets innovative catamarans for
various types of use. The FINTRY Workboat with its distinctive design
has been specially developed for the fast, economic and reliable
service of offshore wind systems. The catamaran design offers various
advantages over hitherto conventional monohulls. For instance, ships
designed in this way offer greater initial stability. The special
feature, however, of all Fintry Marine catamarans is the innovative
sandwich structure made of carbon fibres. The use of this technology
combined with high-grade materials means that it is possible to
substantially reduce the weight of the ships compared to the
widespread aluminium constructions. In addition, the resistance and
robustness of the materials used and the optimisation of the
seakeeping features ensure that the catamarans also set standards with
regard to cost efficiency. Ralph Jensen, fleet captain at FINTRY
Marine Ltd. appreciates the benefits: Our catamarans are not only
faster and more reliable than conventional monohulls and aluminium
ships, they are also economic and environ-mentally friendly thanks to
their lower displacement and substantially lower fuel consumption.
Functional equipment
Two proven techniques are available for powering the boat - either
by twin propellers or water jets. The docking system which can be
adapted to different turbine base systems, and which has buffers that
can absorb impact, also permits precise docking to wind turbines, even
in high waves. Two bow thrusters and the two powerful diesel engines
keep the FINTRY Workboat in position. Comprehensive equipment details
and technology elements enhance the utility value of the ship. On the
working deck there is a large hatch, which facilitates setting up
drilling scaffolding or diver submersion. To assist work on deck, the
ship has a hydraulic crane with an elevation output of between three
and five tonnes. The central cabin offers sufficient space for the
passengers and crew members. It is fitted with a fully equipped pantry
and a room that can be used for a variety of purposes. It also houses
sleeping accommodation in crew cabins, toilets and showers.
Technological head start with added value
The materials used in the FINTRY Workboat have numerous
advantages over conventional ship designs: they are characterised by
high levels of mechanical strength and absolute water tightness. The
maintenance costs can therefore be kept low and the maintenance
intervals long. Nevertheless, catamarans from FINTRY Marine can be in
operation over a period of between 20 and 25 years. The lightweight
sandwich design and an optimised hull line result in a reduced
displacement and a much improved wave image. Speeds of more than 25
knots are thus possible with surprisingly low fuel consumption. For
the operation of the FINTRY Workboats this means: the efficiency of
the specialists used is increased and the operating costs of the ship
minimised. The result is an economic service and thus also improved
operation of offshore wind systems.
The new development stage, the FINTRY-Brødrene Workboat 29m, has a
catamaran hull that has been optimised at the Marine Technology Research
Institute Marintek, Norway, and which can take up to 24 passengers. The
predecessor model Fintry One has already proved itself in numerous
assignments and has given satisfaction with its advantageous features. The
20-metre-long ship offers space for twelve passengers. Both catamarans are
ideally suited for use in the offshore sector.
Maritime regulations exceeded
The FINTRY Workboat is built and certified according to the rules
for high-speed craft (IMO High Speed Craft Code 2000). Approval is
given by the independent foundation Det Norske Veritas according to
the strict regulations of the British Maritime and Coastguard Agency
MGN 280 (M) and other marine standards of Category 2.
