Brazil World Cup 2014 and Olympics 2016 visitors will be able to sail between venues on a fleet of seven big new 2000-seat fast ferry catamarans designed for the job by Holland’s CoCo Yachts and to be built for Rio de Janeiro State by the Afai Southern Shipyard in China. Henk van Herwijnen, General Manager of CoCo Yachts says that the ferrys between Rio de Janeiro and Niterói are expected to carry 100,000 passengers every day, increasing to 150,000 during the international sports events. Rio de Janeiro Ferry: Rendering courtesy of CoCo Yachts People-moving on this scale demands a well-proven propulsion system that for the sake of the passengers is relatively noise-free, provides precision manoeuvrability, and takes up as little space in the fitting as possible. Veth Propulsion (also of Holland) came closest to meeting these demands at the right price and landed a contract to deliver four counter-rotating  Z-drives, type VZ-700-CR (700 kW/1800 rpm) for each of the new ...

The definition describes a hybrid-drive as a propulsion system, which consists out of two different drive-systems. For this purpose at least two energy converters and energy storages must be in use. Apart from some exceptions preferably combustion engines and electric motors are combined into a hybrid-drive.Dutch Veth Propulsions Technical Director Marco Huisman: ”The innovation on this new system is that two different drives are used. The Veth Propulsion hybrid drive offers a lot more solutions for drive profiles, because of its combination of diesel and / or electric motor propulsion. Both drives can be used within their optimal system effectiveness curve. This offers all benefits of a diesel electric drive without any disadvantages.   The hybrid drive features moreover an additional advantage: the asynchronous electric motor can also be used as a generator. In doing so it does not cost any additional fuel compared to a separate running gen-set which runs in low idle &nda... [More]
