AQUACULTURE EUROPE 2011 MATHEMATICAL MODELLING OF AN INTENSE FLOATATION BODY OFFSHORE ENERGY SYSTEMS SA Address: 48 Karaoli & Dimitriou str., GR-152 32 Halandri, Greece Tel . +30 210 6775 003, Fax +30 210 6812 770, www.martech.gr , email : tech @ martech . gr The mathematical formulation follows the same lines as for a free floating body based on Newton’s second law: The total forces exerted on the body (in the three directions) are: F m : Forces from the mooring lines F w : Weather forces (wind, waves, currents) and F w = F h + F l (high and low frequency excitations) F o : Live or operational forces (loads) Presented by : Dr Antonis Daskalakis surge sway yaw THE PECULIARITIES OF AN IFB PROVIDE USEFUL CHARACTERISTICS. HOWEVER INTENSE STUDY BEFORE BUILDING AN INTENSE FLOATATION TECHNOLOGY .

20. AQUACULTURE EUROPE 2011 WAVE ABSORBING TECHNOLOGIES OFFSHORE ENERGY SYSTEMS SA Address: 48 Karaoli & Dimitriou str., GR-152 32 Halandri, Greece Tel . +30 210 6775 003, Fax +30 210 6812 770, www.martech.gr , email : tech @ martech . gr The wave field of an incoming wave can be expressed as follows: In the absorbing cells the field is “broken” to a number of fields Φ i , and diffracted waves Φ d. The outgoing wave field Φ D with less energy content. The forces exerted on the cell surface are of reduced order. THEORETICAL ASPECTS OF WAVE ABSORBING CELLS Field tests of wave absorbers, and of a WAVE ENERGY EXPLOITATION (WECO) apparatus have been contacted in the area of Laurion. The results have led to a complete range of products. A first application is already working in the port of Laurion. Presented by : Dr Antonis Daskalakis
