Front Lord was proceeding en route from Mina Al Ahmadi to Ulsan
when she suffered main engine crankcase explosion
at 2035 LT on 22 Nov 2001.
The position was 06.01N and 090.07E
about 300 m S on the Andaman Is.
As a result of the explosion, a small fire erupted in the ER
which was quickly extinguished by the ship's engineers.
Two engineers suffered serious burns.
The crankcase explosion was due to a damaged crankpin and crankpin bearing
of main unit No 4.
This damaged crankpin was the source of the hot spot
that ignited the flammable mixture in the crankcase.
The damaged [sic] to the crankpin of the main engine crankpin
during the manufacture of the engine.
In this incident, the oil mist detector did not detect
any abnormal level of oil mist in the main engine's unit No 4
and thus the high oil mist content alarm was not activated.
The shields that were fitted to the crank case relief valves
did not offer sufficent protection to the personnel
working near the relief valves
as required by Solas (S74-2/Cll-1/R27.4).
