Van Oossanen Naval Architects of the Netherlands expects to be able to soon optimise bow bulbs and sterns that will help yachts and commercial vessels meet stricter IMO emissions rules.
Niels Moerke, managing director of the Dutch naval architecture studio, says his company has developed software to optimise bulb shapes to reduce main engine power. “Drawing a bulb now still involves much manual labour,” he says.
The first software optimisation tests will be carried out on a 52m inland cargo vessel, “but optimization of the bulb shape is also important for yachts,” Moerke told IBI.
Van Oossanen is active in the commercial and yachting sectors. Since 2009, it has successfully marketed its patented Fast Displacement Hull Form that reduces fuel consumption, creates less noise and creates more onboard comfort.
To date, 30 odd yachts have been equipped with FDHF hulls. A major client is Heesen Yachts of the Netherlands, which has already put FDHF hulls on seven of its yachts since 2014 and has five such yachts in build.
