"Some problems are so complex that you have to be highly intelligent and well informed just to be undecided about them." –Laurence J. Peter (1919-90)
We are all aware of our stormy economy that is being repeatedly rocked by waves of high and low market prices. Then there is the seeming instability of political fortunes and platforms, as the presidential election draws near. Governments are trying desperately to tie down their financial institutions to reduce the fluctuating supply of money and credit. In all these endeavors there is little evidence that there can be any simple, workable solutions.
With such a dreary state to contemplate it is a pleasure to report in this Newsletter that there are solutions for some types of problems involving turbulent wave actions that influence the stability of platforms. We're referring, of course, to the behavior of offshore oil platforms under the action of hurricane force wave fields. Two articles in this Newsletter discuss the dynamic behavior of different types of structures. Responses to waves depend on whether or not the structures are floating, resting on the seabed or tethered with a system of cables attached to the sea floor. FLOW-3D simulations of these cases are used to study wave impact forces, accelerations and amplitudes of platform motion and other features that may be used to determine their overall stability and safety. The best thing is that these sorts of wild behaviors can be brought under your control without losing sleep or your retirement fund.
