Effect of ship hull form on the resistance penalty from biofouling [PDF]

open access: yesBiofouling, 2018
Hull biofouling is a well-known problem for the shipping industry, leading to increased resistance and fuel consumption. Considering that the effects of hull form on resistance are known to be higher for a less slender hull, it is hypothesised in this paper that the effect of biofouling roughness on resistance is also dependent on the hull form.

A study on ship hull form transformation using convolutional autoencoder

open access: yesJournal of Computational Design and Engineering, 2023
Abstract The optimal ship hull form in contemporary design practice primarily consists of three parts: hull form modification, performance prediction, and optimization. Hull form modification is a crucial step to affect optimization efficiency because the baseline hull form is varied to search for performance improvements.

Nominal vs. effective wake fields and their influence on propeller cavitation performance [PDF]

open access: yes, 2017
Propeller designers often need to base their design on the nominal model scale wake distribution because the effective full scale distribution is not available.
