ENERGY ECONOMY ON EXISTING VESSELS

The effects, of fuel prices and their fluctuations, on ship-operating costs are examined together with research and development carried out over the years with the object of saving energy in ship operation. This work has embraced fuel quality and combustion, machinery layout, hull roughness, propeller efficiency, and hydrodynamics. Since the late 1940s shipyards have favoured low-cost building, hydrodynamics and fuel economy taking second place, and until recently there has been little improvement in basic hull form although large improvements have been made in bulbous bows and stern bulbs and afterbody forms by means of numerical analysis methods. Hull roughness and frictional resistance are considered in some detail, including work by BSRA in this field; paint research, are also discussed.
