Awards:

• Recipient of “Nikola Tesla” award 1974 granted by the Ministry of Science and Technology of the Republic of Croatia for the achievement in scientific research in the field of Naval Architecture (Ship Structures) and publishing of the book “Theory of Shells of Revolution”, Ship Research Institute, Zagreb, 1972.
• “Fran Bošnjaković” award 1995 granted by the University of Zagreb for significant scientific, professional and educational contribution to the development and support of the Croatian shipbuilding.

Research activities

The activity is divided into the basic research of numerical methods for static and dynamic analysis of structures, and the applied research for ship and offshore structures wave load and response. This includes:

• shell theory with application to submarine structure design,
• numerical methods for time integration of linear and non-linear differential equations of ship motion in regular and irregular waves,
• ship chaoting rolling and capsizing, slamming etc.,
• ship longitudinal and side launching from horizontal berth by tipping table principle,
• torsion of ships with large deck openings,
• ship and main engine vibration,
• riser dynamics.

Based on the established theories the following computer programs have been developed:

• STIFF for determination of ship hull stiffness parameters for bending, shear, torsion and warping.
• DIANA for flexural and torsional ship hull vibration analysis; free and forced harmonic and transient vibration.
• POZAS for calculation of longitudinal and side launching of ships and floating units.

Professional activities

Together with his collaborators he has performed over 100 commission works for the Croatian shipyards and some foreign clients on submarine structure design, LPG cargo tank design, strength of ships and offshore structures, ship and engine vibration, ship launching etc. Some of the most interesting problems are listed as follows:

• Structure design of catamaran crane vessel, Shipyard “3. maj”, Rijeka.
• Vibration analysis of passenger-car ferry “Amorella”, Shipyard “Split”, Split.
• Vibration analysis of passenger-rail ferry, Shipyard “Uljanik”, Pula.
• Vibration analysis of marine diesel engine, Shipyard “3. maj”, Rijeka.
• Strength analysis of lower derrick substructure of Jack-up drilling unit “Labin”, INA-Naftaplin, Zagreb.
• Structure design of bilobe cargo tanks in Liquefied Gas Carriers, Hartmann Reederei, Leer, Germany.

Educational activities

He was the Head of the Department of Naval Architecture, and at present he is at the Section of Ship Structure Design.
As a Professor of Naval Architecture he has taught many undergraduate and post-graduate courses related to the plate and shell theory, submarine structure design, strength and vibration of ships and offshore structures, dynamics of ships and floating units.
For educational purposes he has issued five text books on plate and shell theory, finite element method and ship vibration.
He was advisor and supervisor for 68 diploma degree holders (B.Eng.), 19 postgraduate students (M.Sc.) and 7 doctoral theses (Ph.D.) in the field of naval architecture and mechanical engineering.
