Mundal Boat AS, who is based in Mundal, Norway, specializes in the design and construction of FRP sandwich vessels up to 35 meters (115ft.) in length.
Mundal’s choice of sandwich composites using
Diab structural cores is based on the fact
that they allows it to deliver vessels that are
lighter, stronger and stiffer than equivalent
steel or aluminum craft. As a result its customers
reap operating economy benefits such
as higher speeds, longer range, greater cargo
capacity and reduced engine power.
Although Mundal Boat is perhaps most well
known for its ocean-going trawlers, it has
also produced a variety of passenger, cargo
and special purpose vessels.
One of its latest projects has been the design and construction of a fish farm service vessels, the first of which is now being
operated by Steinvik Fish Farm AS. At 33.5
meters (110 ft.) long and with a beam of 10.5
meters (35 ft.), it is one of the largest vessels
produced by Mundal to date. Called
the HAV 400 it has three cabins, a spacious
crew mess and a large working deck area
that contains fish collection silos with a total
capacity of 640 m3 (22,601 ft3). Sandwich
composites have been used for all structural
elements of the vessel including the silos.
Sandwich composites are ideal for this
particular application because, in addition to
their weight, stiffness and strength advantages,
they offer high insulation values, are easy
to clean and disinfect and do not rust or corrode
even after long exposure to the elements.
Diab has worked closely with Mundal
for more than 15 years supplying not only
structural cores but also training and process
support services for a wide range of projects.
