Abstract [en]

An investigation of the bunker consumption as function of speed is made, which tries to identify the behaviour of the relationship. A lot of the work is based on a preparatory investigation made by Brita Melén Eriksson at NYKCool that indicates that the consumption is expressed with a specific S-shape. The project confirms that the consumption reported in the material of the fleet expresses the specific S-shape. The specific reason to why the S-shape exists is however not certainly concluded. The behaviour can be found in acknowledged empirical methods of Guldhammer & Harvald and Holtrop & Mennen. However, they also suggest that the ship shall have other dimensions and have an increased speed in order to the S-shape to be expressed in the residual resistance. The statistical analyse of the material suggest an S-shape but with some indications that the S-shape might be an illusion within the material because of practical operational conditions or model manipulations. Further work is recommended for full comprehension of the problem and a reproduction of the investigations by others with equipment and material of higher accuracy is appealed.
