We are now moving forward with the design and all your input has been very much appreciated. We are going to recommend a number of waste heat recovery options to the owner. One interesting area is storing heat to warm the vessel when it is alongside…

For operational consideration I would suggest standard Back-up system, just in case...It could be only a 50% Back-up if cost considération but something there in case ski colling in ont suffisaient or something happend. For flexibilties…

The project is progressing nicely. As the ambient sea water is quite cold (~15C max) we are looking into using skin cooling thereby eliminating the SW Circ pumps entirely. Has this been done before? Any operational considerations?

Flexibility of auxiliary systems is rather easy to accomplish by utilizing e.g. novel automation systems and vfd's for pumps and fans etc.. Savings in fuel costs can be considerable when comparing to a standard technology and as we have…

I like the idea of flexibility within auxiliary systems as they will be running 24-7. Any specific examples of how to accomplish this? There is also a need for considerable flexibility in propulsive power to run efficiently in the summer and still…

John, is that a double ender? If not, I would pay attention on port manoverability and docking procedures to ensure effective departures and arrivals (minimize crossing speed). Considering the 12hr idle time I would also focus on adaptibility and…

Ferry Energy Saving Technologies

Background : Fleetway & Knud E Hansen will be working together to prepare the new design for an 80m-ish ferry for Canadian operation. The ferry operates back and forth on a very short route (~40min) making around 15 trips over a 12hr period. It then sits at the dock until the nexts days service begins (Fogo Island Service). The vessel must content with ice in the winter.Discussion : What fuel consumption technologies are suitable for such a small vessel operating in this sort of service?…See More
