WiSP 2

After a very successful first Wind assisted Ship Propulsion (WiSP) Joint Industry Project, some open ends and new insights were revealed. For this reason a follow-up JIP will be launched. WiSP 2 will focus on making evaluations within EEDI and EEXI, but also from real operational conditions. The aim is to prove what kind of fuel savings shipowners can achieve, enabling them to make informed investment decisions, whilst also keeping the upcoming CII requirements in mind.

WiSP 2 will be the gateway to WASP adoption by the maritime industry. | Patrick Hooijmans,


During installation of monopiles and jackets at sea, the noise generated by high-energy piling harms the marine environment. To mitigate the impact of this noise, governments have adopted noise limits for pile-driving operators and air bubble curtains are used to reduce the sound levels in the surrounding area.

Within the Bubbles JIP, research institutes, companies specialised in installation and marine system suppliers are working together to achieve more efficient and effective use of bubble curtains. The JIP participants aim to get a better understanding of bubble screen use for specific projects, and how they can be improved to control the noise levels, therefore reducing the risks of the installation project.

The Bubbles JIP started in April 2020 and will have a duration of two years. | Linda Kemp,

The methodology consists of a numerical testbed, a streamlined evaluation approach and standardised evaluation criteria. The numerical testbed is linked to MARIN’s existing hydrodynamic models. This testbed allows the control system to be designed within the numerical platform or to connect to external control systems. Systems can therefore be tested by Software- and Hardware- In-the-Loop (SIL/ HIL) evaluation. The streamlined methodology will accelerate the time to market of novel control systems and lower development costs.

The project kicks off in Q2 and will have a duration of two years. | Jorrit-Jan Serraris,

Innovation in Control

Offshore vessels are becoming more and more advanced, with multiple control systems installed on board nowadays. These control systems consist of DP systems, motion compensated gangways, cranes, grippers, etc. But what is currently lacking is a structured, well-defined and broadly accepted methodology to test and evaluate the performance of these systems when integrated on board. Such a methodology allows systems to be tested, optimised and compared from the design to operational stage, and can be used as a contract evaluation method for acceptance tests. The objective of the Innovation in Control JIP is to develop, validate and document such a methodology for the maritime sector.
