Just over a year ago Eco Marine Power Co. Ltd. (EMP) started developing a wind power and solar energy system for use onboard ocean going vessels such as bulk carriers and cruise ships called the Aquarius System. It is an advanced integrated system of rigid sails and solar panels that will allow ships to use renewable, CO2 free sources at sea by utilizing the energy provided by wind and sun. It will also be suitable for smaller vessels such as coastal freighters, passenger ferries and tourist boats and a study is also being conducted to determine if it would be feasible to use the system on naval and government vessel such as patrol ships. EMP estimate fuel consumption reductions of between 10- 20 per cent using Aquarius. A prototype version of the system is planned to be ready by early 2012. [More]
Resulting from a cooperation of the French STX Europe and Stirling Design International, a radical new concept for a cruise ship called EOSEAS was developed. EOSEAS is a cruise ship of 105,000 dwt: Electric power is provided by four dual fuel LNG diesel electric gensets each of 8 MW, supplemented by photovoltaic panels on side and upper deck. There are four screws, two pump propellers with shaft lines on the outriggers and two pump propellers on the main hull. The design claims to have met its objective of reducing green house gas (GHG) emissions by 50 per cent, the reduction in CO2 was aimed at 50 per cent but is expected to be 52 per cent [More]
"We are confident we can build everything up to ocean liners and in fifty years time people will look back at boats of the 20th Century and they'll say – where are the wings?" says Dr Robert Dane, CEO of Australia-based Solar Sailor Holdings, which is collaborating with Japanese company Eco Marine Power and others in the development of concept Hybrid Marine Power (HMP) solar ferry or solar tourist boat Tonbo.
Tonbo in Japanese means ‘dragonfly’ and a glance at the sketches of its folding solar-panel modular ‘wings’ and ‘dragonfly-eye’ forward control station structure will convince how very apt was this choice of name. The solar panel ‘wings’ can be raised or lowered by Eco Marine’s control system: raised to optimise absorption of prevailing sunlight or to increase the field of view from the passenger cabin; lowered flat in bad weather or for transit under low bridges.
Eco Marine’s design philosophy wa... [More]
