A 101-foot tugboat sank at its moorage off the mouth of the Duwamish River
and nearly dragged down a second tug, the AP reported.
The cause of the sinking of the tug island Brave was unknown. More than 20,000 gallons of diesel fuel in the tugboat's tanks leaked before company divers sealed the fuel tanks.
The amount that escaped was undetermined but appeared to be small and was contained by booms.
Someone driving over the Spokane Street Bridge notified
the company about 11 a.m. on January 22 that the Island Brave and Patricia S, to which it was tied, were listing north of the bridge and east of Terminal 5. The Island Brave sank beneath the surface about 1:15 p.m. A large crane on a barge was brought to the scene in time to pull upward on the sinking tug so the Patricia S could be cut free.
