VAF instruments installed TT-Sense® on MV Regal

The TT-Sense® (temporarily without its protective cover) developed by VAF instruments has been successfully installed on MV Regal to acquire precise measurements of propeller thrust and torque. The JoRes project participants will get a unique insight into the challenges and opportunities of ship efficiency. Stay tuned!

You asked we answered!

We received an interesting question on how sensitive would be the developing PIV system to ship vibration usually present at the aft end?

We are happy to answer that this has been our main reason to move from LDV to PIV. The challenge with LDV was to get the two laser beams to intersect. That requires very high mechanical stability of the device when putting in a vibrating environment. A PIV system is inherently more stable, as there’s no need to intersect laser beams at meters distance.

The National Research Council of Canada (NRC) is joining the JoRes project.

The Director General of the NRC’s Ocean, Coastal and River Engineering Research Centre, Dr David Murrin, says: “The NRC is the Government of Canada’s largest research organization supporting industrial innovation, the advancement of knowledge and technology development. With the growing environmental challenges, we share the global maritime industry’s views about the reduction of greenhouse gas emission. Ship energy-saving devices may be a promising solution, but careful and independent studies are required to develop industry benchmarks for these solutions. Moreover, ship-scale PIV measurements of propeller flow have great potential and may help to better understand the principles of these devices. We at the NRC believe that the JoRes project is an important initiative and we are happy to be supporting it.”
