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.

Also, in July 2016 the SHEAR7 v4.9b User Guide was updated to reflect a number typographical changes in the text. The following changes were made to the User Guide:
- The description of Uf in Chapter 1.1.1 has been corrected to match the definition in later sections.
- The Equations relating to Bending Stress Curvature Loading Factor (BSCLF) have been revised to improve the understanding and implementation of this parameter
- Corrected the In-Line Parameters provided in Summary Table G3 to reflect the in-text description.
- Provided further clarification on the default parameters for Higher Harmonics
The new User Guide is available for download from this website. Please note the SHEAR7 software program has not been modified as part of these User Guide changes.
