Frans Sas graduated in Naval Architecture at Delft Technical University, Holland in 1984. He specialised in strength, fatigue and vibrations of structures.
He worked at the university as a research assistant with an assignment to investigate the effects of load sequences on fracture mechanics.
He then joined the Delft Hydraulics Laboratory, and became involved in hydrodynamics. He was involved in manoeuvring studies on simulators and the calculation of strength of structures in water.
During the year 1987 he worked as a consultant for noise and vibrations.
Between 1988 and 1994, he maintained the technical knowledge database at Damen Shipyards in the Netherlands.
As Head of the research department, he was the technical focal point of the shipyard, involved in troubleshooting, the prediction and testing of approx. 50 ships build per year.
From 1995 to 1998 he worked abroad. First he assisted a local yard in Malaysia during the construction of two 22 meter long fast aluminium patrol vessels.
After that he worked as a contract manager on the revitalisation of a 2 km long floating bridge in Guyana.
In 1998-1999 he was project manager during the construction of variouscomplicated vessels like an oil recovery vessel, a hydrographic survey vessel and a mega yacht.
From 1999 to 2002 he was project leader and head of the engineering department of De Hoop Shipyards in Lobith
Since April 2002 he is working as a consultant in SasTech, his consultancy Bureau for Naval Architecture problems, in which he combines fundamental research in new calculation methods for naval architecture with trouble shooting and consultancy (the latter pays the rent).
