On the evening of August 17, 2003 at approximately 2130
the M/T AFRAGEM was approaching Valero Dock #3 in the Corpus Christi
when it suffered a mechanical failure
in that it did not respond to an order for astern propulsion.
The vessel was assisted by two tugs to complete its mooring evolution.
On August 18th the Chief Engineer diagnosed
the problem as a faulty air control valve,
the valve was replaced with another valve from storage aboard the vessel.
A complete test of the system was conducted
and all engine orders responded properly.
