New unstationary test techniques in the MARIN basin

To determine mathematical models, Planar Motion Mechanism (PMM) and rotating arm tests have traditionally been used but with the introduction of the Computerised Planar Motion Carriage (CPMC) 30 years ago, flexibility was added. The installation of a CPMC over a very large basin such as MARIN's Seakeeping and Manoeuvring Basin adds even more flexibility. And now new, unstationary CPMC tests have been introduced. A recent campaign on the 'naval combatant 5415' has been carried out deploying the new tests, which aim to reduce testing time and costs.
