As the world’s energy demand is becoming higher and fossil fuel reserves are starting to become less, more people are starting to think about green energy. The Ocean Grazer is a device that can compete with other methods to obtain renewable energy, as well as the methods for extracting fossil fuels. The device is designed in such a way that it is able to extract the energy of waves. Besides extracting wave energy, the current concept is also able to store wind energy. To extract the wave its energy, the Ocean Grazer makes use of a system which is called the Multi Pump Multi Piston Power Take-Off (MP2TO) system. Several research studies have already been performed concerning the pumping system of the Ocean Grazer. The present report builds on the past models of the single piston pump and measurements that were performed at the University of Groningen. This research that has already been done is used as a foundation to obtain a model which is able to predict the behaviour of the multi piston pump system. By making use of a literature study and analysing the current model that is being used, the parameters of the other two piston subsystems, which have to be added, were determined. The parameters that were determined are added to the Matlab code, which supports the Simulink MPP model. The model that is designed is capable of simulating the behaviour of the MPP model and can provide the different piston combinations. The outputs that the model gave were used to analyse the simulated behaviour. The behaviour which is provided by the model can be verified when the MPP system is working in the experimental setup.
