The prediction of underwater noise emissions from impact pile driving during nearshore and offshore construction activities and its potential effect on the marine environment has been a major field of research for several years. A number of different modelling approaches have been suggested recently to predict the radiated sound pressure at different distances and depths from a driven pile. As there are no closed-form analytical solutions for this complex class of problems and for a lack of publicly available measurement data, the need for a benchmark case arises to compare the different approaches. Such a benchmark case was set up by the Institute of Modelling and Computation of the Hamburg University of Technology (Germany) and the Organisation for Applied Scientific Research (TNO, The Netherlands). Research groups from all over the world, who are involved in modelling sound emissions from offshore pile driving were invited to contribute to the first so-called COMPILE (a portmanteau combining computation, comparison and pile) workshop in Hamburg in June 2014. In this article, the benchmark case is presented, alongside an overview of the seven models and the associated results contributed by the research groups from six different countries. The modelling results from the workshop are discussed, exhibiting a remarkable consistency in the provided levels out to several tens of kilometers. Additionally, possible future benchmark case extensions are proposed.
