That's the company I work for.
It used to be Hamworthy Water Systems at Fleetsbridge. But Wartsila bought us last year.
I'm not involved with the engines though.
I'm in the design office, creating 3D models of water treatment plants and then the production drawings and parts lists etc.
I was looking at some pictures of these engines the other day and nearly posted some on here for some of our bigger boats
Amazing things though !
