We don't see much of the UT 755 these days since the design has been eclipsed by many newer and more swanky models,  but there are doubtless still loads of the more than 100 of them about since they first entered service in the 1990s. This is the Alfanave Cabo Frio, which is, or has been, part of the Edison Chouest fleet, and has been at work out in Brazilian waters since built in that country in 2003.
