LNG-powered Fjord Line Ferries 'World's Cleanest'

Fjord Line's liquefied natural gas (LNG)-powered newbuildings have claimed a new title as the 'world's cleanest ferries'. The Bergensfjord and Stavangerford have won the respective first and second places on the World Ports Climate Environmental Ship Index (ESI), which measures the emissions of over 3000 ships. The LNG-fuelled ferries are both powered by four Rolls-Royce BV12PG gas engines that drive highly efficient Rolls-Royce PROMAS integrated rudder and propellers. Of the 3194 ships currently on the ESI list…

Non-composite Composite Decking: Really?

NyloBoard's Dr. Shae Brown shares global insights on emerging technologies for decking materials. NyloDeck manufactured by NyloBoard is called the “non-composite” composite decking material because it contains no wood or PVC and is not a cap stock product. Its material composition uses recycled carpet fiber and VOC-free resins to create exceptionally strong, durable and eco-friendly deck boards that are impervious to moisture, mold, mildew and termites, and will not swell or rot.

Megayacht Electro-magnetic Propulsion System a World First

The  45m megayacht project involves KaiserWerft, Franck Muller Yacht Design & Engineering and Voith. The semi displacement 45 m yacht will be fully built in Kevlar and Carbon and the (electromagnetic) propulsion is to be powered by a Diesel electric system with new electric propellers from Voith Germany, as part of the Voith Inline Propulsor System, driven by an integrated permanent magnetic (PM) synchronous ring motor. The diesel electric system should result in less fuel consumption…

Eye on Desgin: Improved Propulsion

Fuel saving and emission reduction are motivating factors in the drive to improve marine propulsor technology and in the renewed interest in special devices that improve propulsion. Together with the industry, MARIN is actively investigating their working principles and the critical design aspects, using modern design and analysis tools. Fuel efficiency and reduction of CO2 emissions are expected to have a strong influence on the design and operation of ships. With the arrival of the Energy Efficiency Design Index (EEDI) in 2013…
