Eerste onderwaterspoiler geleverd voor Zr.Ms. Groningen
The hull vane for the OPV Zr.Ms. Groningen that had to be redesigned has been delivered to the Navy and will be installed on the ship in early 2023. I knew this project was being worked on, but I never really payed attention to it, thinking it was just some fancy shmancy new mcguffin. And it is, but they're making some pretty radical claims!
The company Hullvane says their system can; reduce fuel consumption, improve stability and seakeeping and increase the top speed of a vessel!
In the article above, they claim that for the Holland class they can reduce fuel consumption up to 13%. And it stabilizes the ship making helicopter landings easier, and by reducing the wake or waves they claim it makes the ship harder to detect... whatever that means!?! These are some big claims, but they tested it at the
MARIN institute and those guys know what they're doing so there must be something in it.
The guy from Hullvane explains a bit how it works in the article, but it's a bit complicated in Dutch. But something about it being like a spoiler on a car but upside down and under water. But then he's talking about sailing and how a the wind coming from the side creates a force forward.
But anyway, my biggest question is, would this make a ship harder to detect for let's say... a sonar?
