Shipbuilding Department Aims the education of Naval Architects/Marine Engineers following the current technological developments the advancement of the scientific/technological knowledge its techno-economical exploitation by means of engineering applications through research work in areas of the interests the diffusion of the newly acquired knowledge and technological research results in the educational process to further upgrade the level of the offered studies. 4
Recent advances in the curriculum of the Shipbuilding Department Restructure of the offered curriculum to conform with the Bachelor degree level requirements (5A ISCED-UNESCO) Duration of studies: 8 semesters (last semester-degree and practical training course) Introduction of new specialized courses (Ship design and Small Craft Technology, Local Ship Strength, Inspection Repair and Maintenance of Ship Structures, Offshore Structures, Shipping Computer Aided Ship Design) Students training CAD systems and software, as, e.g., AUTOCAD, AUTOSHIP, (see Fig.1), and MAXSURF packages. 5
Research in the Shipbuilding Department Advance of scientific knowledge Development of collaboration between the academic staff external researchers Secured funds from EPEAEK II programme ARCHIMIDES I, II calls Optimization of Shipbuilding Technology Aiming at Protection of Marine Environment against the Oil Pollution Investigation of Marine Diesel Engine Robust Control Augmented Disturbance Rejection 6
ARCHIMIDES I Project Objectives New technologies for the protection of the Marine Environment from Oil Pollution Magnetic oil-absorbing technology for combating oil spills (CleanMag Technology) Prototype vessel for the implementation of the oil absorbing technology Further research for optimizing the vessel design to the CleanMag Technology 7
ARCHIMIDES I Project Objectives (a) The development and enhancement of mathematical models for the forecasting of sea wave characteristics in the and the coastal area, and their impact focused on subjects concerning extreme events in coastal zones and events of pollution from oil spills. (b) The development and enhancement of mathematical models for the propagation of pollutants in conjunction with wave models. (c) The exploitation of the above in the development and optimization of a shipbuilding technology in order to solve problems related to oil pollution in the coastal environment. 8
ARCHIMIDES I Project Objectives Comparison between the prototype built vessel and one of studied double hull family for optimal implementation of the CleanMag Technology 9
