Full scale measurements of the propulsion power, ship speed, wind speed and direction, sea and air temperature, from four different loading conditions has been used to train a neural network for prediction of propulsion power. The network was able to predict the propulsion power with accuracy between 0.8-2.8%, which is about the same accuracy as for the measurements. The methods developed are i...

Advances in power and propulsion energy management improvements can significantly contribute to reducing emissions. The International Maritime Organization (IMO) Marpol regulations impose increasingly stringent restrictions on ship’s emission. According the measured data of target ship typical working profiles, fluctuation, fuel consumption emission are analyzed, result represented that there s...

18 High-Frequency (HF) radars are operated in the 3-30 MHz frequency band and are known to cover ranges up to several hundred kilometers. Low power HF radar systems have been developed especially for oceanographic applications. They use electromagnetic surface wave propagation along the salty ocean. The WERA HF radar system transmits an average power of 30 watts but it achieves detection ranges...
