Public Defence in Marine Technology, M.Sc. Janne Heiskari

Passenger experience is a top priority in the design of a new cruise ship. One fundamental experience is immersion in the surrounding ocean environment, which is maximized by covering the ship with windows. However, since the size of the ships has significantly increased in recent decades, so has the glazed surface area. Since ships are weight-critical structures, the windows should be designed as lightweight as possible. Unfortunately, the current rule-based design methods cannot fulfill this requirement. Therefore, this dissertation aims to improve the design framework for insulating glass unit (IGU) type windows on ships. Based on five engineering strategies, a more accurate thickness calculation method for the glass panes is presented. It is then used to study the influence of different design variables on the IGU weight and bending behavior. As an outcome of this dissertation, the ship designers know better how to efficiently design lightweight IGUs, potentially allowing for even more glamorous glass structures on cruise ships than before.
