Apparently a hull leak unloading at Northside Generating Station
on the St Johns River.
Captain Matthew Woods of the USCG
said "maybe 100 gallons".
The exact cause of the leak was not known
but Woods said the oil might be coming from a bad weld.
This source says the owner is Caluna Inc of Italy.
Woods referred to a much larger spill
(called 500,000 gallons in this source)
in Savannah earlier in the month
and said the ship may be refused entry to the US
in the future.
