This was a very high profile spill in part because
Venezuelans detained master for about six months.
Most sources put the spill around 25,000 barrels or 4000 T.
OSIR says 8571 T, but have no back up.
Ship was outbound at night with local pilot on-board.
Owners claimed channel had not been maintained.
But Venezuelan courts found master guilty.
Interestingly, the Olympic Sponsor, a double hull ship
went aground at nearly the same point (buoy 22) on March 10th two week later,
holing the No 4 S ballast tank, but no spill.
The master and pilot claim they were in the channel
when the ship slowed to less than 3 kts despite full power
and then was set over to the west side of the channel by the wind.
The Olympic Sponsor owners went against charterers Lagoven
claiming violation of the safe port clause in the charter party,
given the fact that Lagoven had instructed the ship to load to 38 feet.
Arbitrators found against the owners saving nav error
and anyway safe port clause not enough to blame charterers.
Nonetheless, on the day following the Olympic Sponsor grounding,
the harbor master reduced the exit draft to 36 feet.
Seems quite unlikely we are talking about a submerged object
if a midship tank is holed.
One source says there was another grounding in the same area,
a tanker called the Icaro.
Anyway we need the outbound draft, which tanks were breached, pentetration,
loading plan etc.
It is interesting in all the hype about the Master being detained,
fisherman protects, etc, etc, we can not find such basic info.
But current CTX best guess is that the ship was loaded
to deeply for a poorly maintained channel.
