of course it is, how else are you going to create a drill string that needs to grow to 10000m+ long? drill pipe is flexible(ish, for varying definitions of "flexible") but not nearly enough to do a coil of it for that long. coil tubing is a thing but is much thinner and smaller diameter and isn't nearly as strong. it also can't rotate.

drill string comments aside, this appears to be a very standard deepwater offshore drill ship
