PREDICTING WIND RESISTANCE OF CONTAINER VESSELS BY DIFFERENT APPROXIMATED METHODS

Abstract

The container vessel Fortuner Navigator (CV FN) belongs to the Vietnam Ocean-going Ship Company (VOSCO). The fleet is container type and operated voyaces between Hai Phong and Ho Chi Minh cities (Vietnam). Normally, the sea conditions usually are un-normal for the ship exploitation and the sea-wave and wind are scalled from IV to VIII via Beaufort Number (BN).  In these un-normal conditions, the two hull resistances components (R_AW and R_AAW) are additional and appeared in accordance with the ship hull working on the heavy sea-wave and wind conditions. The total hull resistance in accordance with the BN of the sea-wave is rapid increased comparing with the one for the newly building sea-going ship (the designed, calculated in the normal conditions). The paper presents the predicted results of the sea-wave wind resistance R_AAW by some aproximation methods for MV FN exploitation at sea, in 2015. The authords modeled by the regressive models with 99%- confidences (in accordance with the statistic criterions Fisher and Schi) for predicting the R_AAW.The module software coded by authords in Labview for automatic predicting the R_AAW in accordance with the different selection methods, rellativelly.
