COMPILE II - A Benchmark of Pile Driving Noise Models against Offshore Measurements

In the last decade, underwater noise pollution from offshore construction activities gained increasing attention. Due to complexity and costs of offshore measurements, prediction models to quantify the noise emission and to optimize the construction process are required. For the prognosis of pile driving noise, several different models already exist. Many of the approaches have been compared in 2014 in the frame of the first international COMPILE workshop that has been initiated by Hamburg University of Technology (TUHH) and Netherlands Organisation for Applied Scientific Research (TNO). Thereby, the benchmark case for the workshop was based on a rather empirical setting with several simplifications and was not related to any real offshore project. To go a step further, a follow-up workshop COMPILE II has been hold in 2017. Beside TUHH and TNO, E.ON Climate & Renewables helped to define a realistic benchmark scenario, for which corresponding offshore measurement data was available. A total of eleven research teams from all over the world attended COMPILE II and submitted a prognosis based on their own models. An overview of the results and the major findings is given in this contribution. To learn more about COMPILE II, visit https://www.tuhh.de/mub/compile.html .
