SHEAR7 is the offshore industry’s leading software tool for the prediction of Vortex-Induced Vibration (VIV) with close to twenty years of industry use and continuous development. The program’s forte is the VIV response prediction of offshore structures subjected to spatially varying currents; realistic of ocean environments. The program enables users to estimate structural responses, drag force amplification factors and predict fatigue damage. SHEAR7 couples to other offshore system modelling tools such as Orcaflex and Flexcom enabling VIV assessment through the front end of these packages. It is simple and fast to run with all the results summarized in a convenient standard output file. SHEAR7 is used throughout the world by engineers in Australia, Brazil, China, Denmark, France, India, Japan, Korea, Malaysia, Norway, Spain, UK and USA.
