PTO development with Siemens Industry, Fritz Schur Energy and Contech
Based on the wave, absorption, movement and load measurements from test phase 1 and 2, the wave PTO system was designed for the P80 device. Based on this design, the PTO system for P37 was re-designed and constructed in corporation with Siemens Industry, Fritz Schur Energy, Contech and others. This system was dry-tested before starting the offshore tests. The PTO design work was done in parallel with extensive wave flume testing at DHI to validate and optimise the absorber and the absorber chamber design.
Results: Design validation and scalability to P80, redesign to P37 and aggressive reliability tests. PTO is ready for offshore tests and reduced weight/material use for the P80 platform. The wave flume testing increased wave absorption by over 25% and reduced the absorbed size by over 50%
