Becker Marine Systems, along with Bureau Veritas, is using carbon composites to develop propulsion components with new or better properties
According to Becker, carbon fibre provides two main advantages:
Weight savings of more than 50 percent enable easier handling during transport and assembly, making this suitable for advanced naval applications focusing on light-weight structures. In addition, a reduction of raw material waste of 60 percent compared to forged steel helps achieve a lower carbon footprint. Due to the huge potential of composite materials it is expected that the number of composites and their application in merchant shipping will rise in future.
For smaller components, like rudder flaps, composite materials enable the manufacture of hull surfaces with better propulsion properties, as a slim design provides less drag and improved lift. Composite rudder flaps are available for all types of Becker high-efficiency rudders such as FKSR, SA/SC and Heracles rudders.
Becker also offers composite material for rudder stocks (pictured). The weight of a rudder stock for a 8,400 TEU container ship e.g. can be reduced from 72.2 t to 26.6 t by using the new material. By specially adapting the fibre arrangement to meet the requirements for each different type of rudder, Becker ensures long equipment service life at the lowest operating costs.
The use of composites within the rail industry is predicted to grow by up to 40% between 2015 and 2020 according to the Composites Leadership Forum, reports Fibrelite, a UK manufacturer of composite trench covers.
Plasan Carbon Composites (PCC) has been awarded a contract to produce the first composite ramps and bridgeplates for Amtrak.
