DNV GL has honoured a young engineer for his scientific thesis that studied the “Optimization of Ship’s Bow for Added Resistance in Waves”.
The DNV GL Award for Young Professionals in the “Greener” category was presented to Victor Bolbot by DNV GL’s Maritime CEO Knut Ørbeck-Nilssen at the Posidonia trade fair.
Bolbot’s work demonstrates a key trend in ship design, namely the consideration of realistic operational profiles and realistic ambient conditions. DNV GL commented that Bolbot combines simple design estimates for calm-water resistance with a semi-empirical approach for the added resistance in waves and that he showed that moderate changes in the bow can lead to lower EEDI values. His research also demonstrated that optimisation also favors a straight vertical bow rather than the currently popular bulbous bow designs. This is confirmed by more sophisticated CFD analyses and is also in line with DNV GL’s recent findings from its Green Dolphin project for future bulk carriers. The work combines current software tools with classical naval architectural estimates, to find a good trade-off between time, cost and accuracy. The thesis is a valuable contribution to energy efficient shipping.
