Shear wave velocity methods are well established for geotechnical site investigations on land. Presently, acoustic-based systems are the predominant means of seismically investigating offshore sites. There is great potential for applying shear-wave based methods to the offshore environment to measure the shear stiffness of sediments, a characteristic that is not measured with acoustic-based systems. As the offshore industry moves into water depths exceeding 1500 m, the demand for innovative methods of geotechnical site characterization will be more pressing. The present state-of-the-practice in offshore shear wave velocity measurements is reviewed. Limitations on operational water depths and subbottom profiling depths are discussed. Lastly, a brief examination of some potential applications of these methods in the offshore environment is presented.
