Hi David and Kelvin,
It seem like they are trading like bulkers, but at the owners website they are still listed as PROBO type (http://www.gulfnav.com/fleet_list.php), so I am getting a bit confused.
Best regards,
Geir

And strangely LR has JASH and SIEB already converted to bulkers. So perhaps they all are now!

Yes, the specific (and very recent) DNV change is, I would say, definitive. Agree apparently not now trading as an obo. Looking at the DNV records for this class GULF AHMADI/RIYADH/SAFWA all now converted to straight bulkers; but GULF JASH/SIEB still classed as OBOs. Looks like a gradual change of them all

I don't think so David; although Equasis says OBO, DNV classes it as a Bulk Carrier.
DNV does show a change of type on 1 Nov 2010 while Equasis shows OBO as of 1986 so I guess it is now a bulker.

IMO 8315396

Should be categorised as "OBO", I think.
