William Otto has been educated as a naval architect at the TU Delft with a specialisation in ship hydrodynamcis. His main field of expertise is the dynamic behaviour of moored constructions. This expertise has been obtained by performing numerous model test campaigns at MARIN for, among others, FLNG’s, FPSO’s, semi-submersibles, drillships and floating wind turbines. Lately his focus has been shifted to large scale flexible, or piece-wise flexible, floaters. The application of these are in the field of floating islands creating multi-purpose deckspace. Next to model test campaigns, William Otto is involved in the development for complex mooring simulations for flexible and piece-wise flexible floaters with many-bodies in the Space@Sea EU project.
