Innovative New Technologies Increasing Ship Capacity And Speed, Whilst Reducing Construction And Ope
Vancouver based ship design and research company is bringing to the market a number of new technologies for both oceangoing and inland waterways vessels. Technologies protected by patents in USA, European Union and several other countries, four already granted, another three pending.
The winged bow. The new geometry of the oceangoing vessel bow reduces resistance of the hull resulting in either higher speed, or less power, fuel consumption and GHG emissions. It also reduces motions in waves, shown in testing and in operation to be 50 percent lower than conventional bow fitted hulls, and eliminating slamming, therefore making it possible to design lighter structure. It also increases capacity of the hull or reduces it length and cost for given capacity.
The flow spinning stern bulbs. The new geometry of the stern bulbs spins the flow of water into propellers counter to their rotation, increasing their efficiency.
This has recently been delivered to Navimag Ferries in Chile. MV Esperanza design combines these technologies to such effect that this 150m, 10500 mt displacement vessel needs only 2500 kW into her propellers (1250 kW each) to sail at 14 knots, with capacity of 1800 l-m on only two decks. This makes MV Esperanza so efficient that her EEDI (Energy Efficiency Design Index) not only meets present but also future IMO targets without a need to reduce speed, as many operators are presently forced to do in order to meet IMO emission standards.
