Research profile

From very beginning research area of chair workers has been focused on problems of manufacturing and maintenance of floating objects. Detailed description of research profile – in bookmark.

Department collaborates in commercial level with shipbuilding sector companies as well as with some other market enterprises.

Educational Profile

As baseline educational profile, the chair gives lectures on technology of ship manufacturing and repair technology, problems of outfitting as well as problems of economy and management of production. We teach also manufacturing techniques like welding, materials as well as relations of manufacturing quality and the matters of strength of materials and structures. On MSc course we give lectures on problems of ship structure failure, exploitation strength, role of Classification Societies, global shipping market analysis, project management and introduction to quality systems in industry. Into study program we included problems of modern material and technologies like laser welding and application of steel, laser welded sandwich panels into ship structure. Starting from 2004 the Department has been carrying out post diploma studies ISO Standards and TQM (in polish).

Laboratory of Marine Structures

Laboratory occupies area of 600 m²

 

Basic  equipment

• Experimental stand for static and fatigue investigations of full-sized structural elements or ship hull structure models dimensions of up to 17 m x 7 m. The instrumentation of this stand consists of steel frames of 7 m and 5 m span respectively, allowing different supporting, fixing and loading of the tested structures with complex modes of the boundary conditions. Each frame can carry the static and dynamic forces up to 5000 kN and 2000 kN in vertical and horizontal directions respectively. Load is generated by set of hydraulic actuators with capabilities up to 1000 kN each, which can be coupled to create different combinations – controlled by system Instron-LABTRONIC 8800 with possibility of generating of different type and range of static and fatigue load in four channel simultaneously.
