Jiří Sládek General Contractor ASIO, spol. s r.o., Czech Republic Engineering Office Jaroslav Pražan, Plastic Structures Design Construction Period 08/2009 - 09/2009 The purifying technology is based on the collection of biomass from the water surface and separation of biomass particles on a mechanical filter. The biomass contains a large quantity of nutrients that would otherwise settle in the form of organic compounds in the bottom sediment. This technology does not add any foreign substances to the water and the entire principle is very environmentally friendly. Dimensions: length 12 m, width 2.4 m, height 2.38 m. Material Polyethylene PE100. The boat geometry was modelled using plate and shell elements. The iterative process was used to determine the loading equilibrium state, with zero reactions, corresponding to a floating boat. The iterative nonlinear incremental indirect stability analysis followed and it proved the dimensions of the boat construction. The main challenge was the iterative calculation of the equilibrium state and the indirect incremental nonlinear stability analysis. The preparation of the documentation was easy and productive thanks to the integrated Engineering Report.
