Crazy thought... those III III (and iii iii) are sorta "ventilation holes" if you could imagine that grey areas are of plastic & whole ship is a some robot-like thing, so that would make those black broken lining on her hull & radars as "edges" between the elements that can "retract" one from another.

2nd mate just looking at the AIS and laughing!

1st mate: (looking in the binoculars) A some "OCEAN... PLORER", sir!
Captain: OCEAN what?
1st mate: Plorer, sir!
Captain: You mean "EXplorer"?
1st mate: No, "Plorer"...
Captain: what's a plorer? Wait, lemme see myself! (looks hard) "OCEAN... PLORER" hmmm whatever that means... Well, so Plorer it is then.

Mysteries, Denis, they are actually IIIs with small IIIs above them.

What are those III III all over on her?

Funny, I asked the same question in the description when I posted my own shot of this ship a couple of days ago, and got no reaction whatsoever. Now that I ask this here as a comment I get three in 20 minutes.
So why am I bringing this up? I think the description should, at least be partially visible together with the thumbnail. There is enough available space. It will invite people to present more interesting description, and will reward the photographer with answers.

Ooop's my typo with the extra E !

And to further complicate matters, DNV-GL has it as OCEANXPLORER1

Well, one thing is for sure, it's XPLORER and not EXPLORER...

Equasis have the spelling as OCEANXPLORER 1.

According to their website it is just OCEANEXPLORER ?

So the last small character in the name is what? a 1 or a I or what else?
