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 models already exist. Many of these approaches have been compared in 2014 in the frame of the first international COMPILE workshop that has been initiated by the Hamburg University of Technology (TUHH) and the Netherlands Organisation for Applied Scientific Research (TNO). Thereby, the benchmark case for this workshop was based on a generic pile driving set-up 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 held in Hamburg in November 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. Beside a description of the COMPILE II benchmark case, also an overview of the results and the major findings are given in this contribution.enConference PaperConference Paper
