New Hullform Design for Dual-Fuel Vessels Lowers Fuel Consumption
A design for a vessel using lliquified natural gas (LNG) as bunker fuel can deliver lower fuel consumption, an industry conference has heard.
US marine technology company HydroComp presented work on hullform hydrodynamics, duty profile analysis in dual-fuel operation and prediction of carbon dioxide (CO2) greenhouse gas production to the Power and Propulsion Alternatives for Ships conference organised by the Royal Institution of Naval Architects in Rotterdam, according to maritime technical news provider Passengership.
HydroComp technical director Donald MacPherson said that new capabilities in the company's NavCad software were applied to predict resistance and to identify a "longitudinal wave source" distribution where the influence of local hullform shape can be evaluated for its contribution on resistance.
This information was applied during design to reduce hull resistance by some 10%. The modified design with an alternate dual-fuel (marine diesel oil-LNG) engine achieved a 14% reduction in propulsion energy demand and a 34% reduction in CO2 production, MacPherson said.
HydroComp's partners are NAP Engineering, Helengi Engineering and Blue Star Ferries.
