Abstract
The effects of poor hull surface conditions on fuel consumption and emissions are well-known yet not thoroughly understood. Therefore, the present study investigates the effect of widely adopted fouling control coatings and mimicked biofouling on a full-scale representative ship, the KRISO Containership (KCS). Different surfaces were tested in the Fully turbulent Flow Channel (FTFC) of the University of Strathclyde (including a novel hard foul-release coating, commonly used antifouling, barrier resin, soft foul-release coatings, and sandpaper-like surfaces). Then, the corresponding roughness functions developed for the test surfaces were embedded in Computational Fluid Dynamics (CFD) simulations using the modified wall function approach. Interestingly, the numerical predictions on the KCS hull showed that the novel hard foul-release coating tested had better hydrodynamic performance than the smooth case (maximum 3.6% decrease in the effective power requirements). Eventually, the present study confirmed the practicality of the FTFC used in combination with CFD-based studies to predict the effects of hull roughness on ship resistance and powering.
