May 22, 2023 – It’s great working together with Aktis Hydraulics to develop technology that not only identifies the risk of parametric roll very precisely, but that is also capable of showing the onboard crew how to mitigate this risk by either changing the vessel course and/or speed in the current sea state.

Aktis Hydraulics has worked on the mechanisms behind parametric roll, which as resulted in a reference to their work in ‘Guidelines for Parametric Roll Countermeasures’, released bij ClassNK.

The guidelines cover a wide range of aspects including the mechanism of parametric roll, its features and precautions, an overview of parametric roll response calculation, and devices and methods for countermeasures such as a practical and reasonable way for creating a polar chart that illustrates the danger of parametric roll.

The team at Aktis Hydraulics together with NextOcean are continuing to synthesize lessons learned with analysis of parametric roll forecasts and to improve predictability and operational safety at sea.
