The 2003 built 301,000 dwt crude oil tanker Iran Hengam
bound for Singapore was reported adrift with engine problems
SE of Krisiansandon [sic] on 20 January.
The vessel then reported it engines were running,
but not at 100% and proceeded at reduced speed to effect repairs.
Assuming Kristiansand, and assuming loaded.
Probaly was reversed lightered in the Kattegat.
Sulzer 7RTA-84T, sounds like they may have pulled a piston.
