INFLUENCE OF SERVICE CONDITIONS ON THE RESISTANCE OF CERTAIN TYPES OF CARGO SHIP

The principal factors which cause an increase in ship resistance in service are weather and the condition of the Hull surface. The former is governed by wind force (as measured on the Beaufort scale), and the latter by corrosion and fouling of the hull plating. The paper summarises quantitative studies of these factors. Among the general conclusions are the following: 1. After a year in service (since dry-docking) the resistance increases by 21-38% (this result assumes an average wind force 6). 2. Fouling causes an increase of resistance ranging from 3.5 to 11.5% after a year in service. 3. Surface roughness due to corrosion and mechanical damage increases the resistance by 6-9% after three years in service. Order from BSRA as No. 49,840.
