Sweden’s leading shipbuilder Kockums AB (a part of Thyssen Krupp Marine Systems) in conjunction with FINTRY Marine is now offering a range of commercial catamaran vessels that set new standards in terms of performance, fuel utilization and through-life economy. Currently the vessels range in size from 18 to 60 meters (60-197 ft.) and are built using advanced carbon fiber sandwich technology based on Diab structural cores resulting in a weight reduction by 30 % compared to aluminium. Called CarboCAT® the flexibility of the catamaran platform allows them to be readily configured as offshore support vessels, ambulance boats and fast passenger ferries.
The use of advanced sandwich composite
technology and infusion molding has
enabled Kockums to reduce the structural
weight by 30% compared to aluminum
vessel of the same capacity. This saving in
weight can cut fuel costs by more than 20%
and reduce the CO2 footprint of the vessel.
At the same time the low maintenance requirements of sandwich composites compared to aluminum means that Kockums would expect operators to see a 25% reduction in maintenance costs and an increase in the service life of the vessel.
Other benefits of the sandwich approach include excellent safety characteristics, built-in buoyancy and good thermal and acoustic insulation.
The first DNV approved CarboCAT
is already in service following an ‘order to
launch’ build program that took just 13
months. Called the ‘CarboClyde’ it is the
first of a series of 23.4 meter (77 ft.) long
offshore support vessels that will be initially
deployed to service the Baltic 1 offshore
wind farm. This is the first commercial offshore
wind farm in the German sector of the
Baltic Sea. It covers an area of seven square
kilometers (2.7 sq. miles) and features 21 turbines
that will yield 48.3 megawatts.
At its service speed of approximately 25
knots the ‘CarboClyde’ is capable of transporting
up to eight tons of material and 12
to 24 technicians.
Cargo can be transported on its large
sheltered cargo deck and a large crane,
forward of the cargo area, makes the
‘CarboClyde’ partially independent of external
lifting facilities. The combination of
two water jets and bow thrusters enable the
craft to offer excellent maneuverability at
close quarters and at slow speeds. The forecastle
deck features a docking system for the
safe transfer of service personnel between
the vessel and offshore wind turbines.
Diab is now working on a development
project with Kockums to quantify the benefits
of moving to
3D infusion kits for future
CarboCAT vessels. With
3D kits, components
such as stringers are included
as part of the one
shot infusion process rather
than being added
later as a separate manufacturing operation.
