The effect of pile driving noise on the marine environment is an important factor in environmental impact assessment of planned marine structures, such as ports, bridges or offshore wind farms. Numerous models have been developed to predict the noise levels to be expected from such activities and to advise suitable mitigation measures to concur with different national and international regulation. A recurring problem in the validation of such models is the availability of acoustic measurements, as this is both costly to obtain and difficult to share across different research groups due to commercial sensitivity. To address this problem and compare a number of existing models, the first COMPILE workshop was organized by the Hamburg University of Technology (TUHH) and the TNO in 2014. A generic benchmarking case was then specified to compare various modelling approaches. Simulation results were compared at various depths and ranges between ten meters and fifty kilometres and the broadband results of all models were found to be in very good agreement, for this relatively simple case. In this contribution, the benchmark case for a second workshop (COMPILE II) is presented. The COMPILE II case was set up by TUHH, TNO and E.ON Climate & Renewables and is based on a real-life example, allowing for a model validation based on measurements. A detailed discussion of all relevant model parameters for the pile and the environmental conditions will be given as well as a description of the desired model outputs for later comparison to measured quantities.
