According to the IMO`s climate protection plan, CO2 emissions from all ships should be eliminated by 2050.
Two paradigms of conventional shipbuilding need to be reconsidered:
1. Ships are made of steel (or aluminum):
Thanks to new composite materials, primarily from aircraft construction, we can now save half the weight and half the propulsion energy compared to aluminum ships. This reduces fuel consumption and in fully electric ships, the battery size can be reduced. If we do not have many more composite lightweight ships in the future, we will not make any further progress in minimizing energy consumption..
2. Composite ships are built in negative moulds:
The yachts in the marina are usually manufactured using negative moulds. However this constuction method is to costly for large, customized ships, mainly due to the cost of the negative mould and the additional interior cladding required.With our constuction technology, deverloped over 15 years, using large-format. high-strength, industially manufactured sandwich panels in FR quality, such ships can be built very cost effectivelly. If we do not abandon the idea of negative molds for larger ships, we will not be able to build cost-effective this ships.
