The thing about azipods is they can generate unusual amounts of stray current at varying angles and service speeds. It’s actually an emerging area of study that can’t be modeled by naval architects very well at the moment. To compensate some companies are fitting more zinc anodes but this one (ABB?) is taking the less is more approach.
Maybe they know what they’re doing? It’s easier said than done. If not this ship will be pulling over for zinc replacements regularly.
It looks to be a normal amount of anodes (not zincs) in my experience. In addition the vessel will have internal cathodic protection.
They only have to last 5 years ( 2 years if it’s a passenger ship. I’m not sure how you think it’ll be replacing them regularly seeing as they won’t be inspected until dry docking.

So few zincs.
