About LASS
Within LASS, several new design and calculation methods will be developed
in order to facilitate the use of lightweight materials at sea. Technical
problems, such as methods of fastening and jointing, strength, fire
resistance, vibration, acoustics, as well as legislative 'thresholds' for
lightweight designs, will be investigated. New materials will be tested and
LCA/LCC design procedures developed. Conceptual studies will be made on the
following type of ships:
A wholly composite ship
This is a continuation of the existing leading edge knowledge of
construction of entire craft from carbon-fibre sandwich material and use of
the new vacuum injection technology. It is most important further to reduce
manufacturing cost through the use of new materials, new design solutions,
new calculation methods and new production methods.
Aluminium hull with composite superstructure for a high-speed ferry
Previous high-speed ferries usually have had aluminium superstructures. A
structure of sandwich material composites would have better fatigue life,
noise reduction, thermal insulation, impact resistance and lower weight.
Steel hull with composite or aluminium superstructure for a Ro-Ro
vessel
Ro-Ro vessels are built today essentially only of steel: there is no mixing
of materials. There may be some lightweight materials in the form of doors
or interior fittings, but not in actual structural parts of the vessel.
Using aluminium and/or composite materials for parts of the vessel could
lead to substantial weight saving, reduced maintenance costs and improved
stability.
