Career Summary
Dr Bogdan Ganea is a Naval Architect specialising in Hydrodynamics.
Background
Bogdan was a senior researcher of Icepronav (Shipbuilding Design and Research Institute) in Galaţi, Romania. His career spans over 30 years in the field of ship experimental and numerical hydrodynamics. He developed CFD code for steady and unsteady propeller calculation by boundary element method presented at the 22nd ITTC Propulsion Committee Propeller RANS/Panel Method Workshop, 5-6 April 1998, Grenoble. His experience includes also speed-power and manoeuvre sea trials conduct and data processing. Since 2009, he has been developing an in-house software for manoeuvring simulation, BBSIM – Brookes Bell Manoeuvring Simulator, which is deployed in numerous commercial projects for accident analysis and berthing / unberthing simulations under various environmental conditions. This code was also deployed in the SAFEPORT research project for ship trajectory optimization.
