A tugboat struck and ruptured a tanker
causing an estimated 50,000 gallons of heating oil
to spill into Boston harbor yesterday,the U.S. Coast Guard said.
The tanker Posa Vina was leaving from the Tosco marine terminal
in East Boston when the tug struck and punctured its port side
2 feet above the waterline at 830 am, the Coast Guard said.
"That particular fuel tank was holding 400 tons (or about 112,000 gallons)
of No. 6 fuel oil," CG Lt Rebecca Montleon said.
"We estimate that 50,000 gallons spilled."
By shifting the remaining cargo on Posa Vina,
the crew was able to list the vessel to the starboard side
so that the spillage was stopped, she said.
