Researchers of Hamburg-Harburg Technical University have simulated, in a spectacular test, the impact of a rogue wave hitting a cruise liner's window. HBM's Genesis HighSpeed system ensured reliable data acquisition during the test. Transparent, light weight, bright and spacious, large-size windows are increasingly being installed on large cruise liners which adds an architectural value to the cruise line, however, raises many questions regarding the ship's design. Wave impact is a particularly critical issue: What are the requirements for the design of ship's windows to be met to enable them to withstand the impact of large masses of water? Would the windows presently installed be able to withstand a so-called "rogue wave"?
An encounter with a rogue wave - though extremely rare - is a conceivable scenario. Ship accidents and encounters with occasional large "rogue waves" have time and again been reported over the past decades: reality or sailor's yarn? Only since September 11, 1995, when a rogue wave hit cruise liner Queen Elizabeth 2, is this phenomenon considered scientifically validated and proven.
Research of the topic has just begun - covering various aspects of ship design as well. What are the design requirements for ship components, for example, windows, to enable them to withstand the enormous force of a rogue wave hitting the ship? Can a window withstand a rogue wave at all? There is an increasing need to answer these questions, now more than ever since large are increasingly being installed on modern ships.
A research project led by Professor Wolfgang Fricke of the Institute for Ship Structural Design and Analysis of Hamburg-Harburg Technical University investigates the questions arising from the use of increasingly large windows on ships - also considering wave impact and even an encounter with a giant rogue wave.
