CRS webinars on Propeller Optimization and Structural Monitoring

May 12 2021
Reading time
The Cooperative Research Ships is a unique community of 24 maritime organizations working together in real Public-Private Partnership. CRS started in 1969 with the intention to obtain general data about the hydrodynamics and related problems of large and high-powered ships. Today the research carried out by the CRS focusses on hydrodynamics, structural and related problems of all kind of ship types from a fundamental, design and operational perspective.

The CRS SHARE webinars are a unique opportunity to learn more about typical research conducted in our working groups. For more information about CRS visit |


The Propagate II working group focusses on the application of multi-fidelity propeller optimization using RANS and BEM methods. The framework, goals and constraints developed in Propagate I are applied to actual design cases from industry. This webinar will focus on the BEM method as applied to day-to-day design and which has been extensively used to design the new Wageningen F-series propellers.

STRUCTURAL MONITORING, June 8, 16:00-18:00

The CRS iSHIP working group aims at increased safety combined with lower ownership costs. This can be achieved by improving platform management and maintenance practices with improved assessment methods, understanding the influence of the operator’s choices and informing future designs. Specifically, iSHIP has developed virtual hull monitoring techniques enabling automated structural assessment without additional instrumentation.
