Yes, junk scrap metal that made a nice bar across the door.
The ship was one of the late casualties of the break up of the Soviet Union. Oddly enough it was built in a Ukrainian shipyard. The paint was probably the primer before a finish coat when the ship was laid up for overhaul. That was never completed. Instead the ship was simply removed and docked.
Lots of Soviet naval vessels undergoing repair or construction such as the Chinese carrier met a similar end. The Chinese carrier was originally abandoned by the Soviets at the same complex that built the now scuttled ship.
