_________ on the hull is done to increase the vessel hydrodynamic performance
Direct Answer
Option D: removal of fouling on the hull
Hull fouling, caused by the accumulation of marine organisms, significantly increases hydrodynamic drag and fuel consumption. Regular cleaning and maintenance of the hull surface are essential operational practices to maintain vessel speed and efficiency, directly supporting the energy efficiency objectives outlined in the IGF Code and MARPOL Annex VI.
