On April 20, the 30 meter long tugboat Powhatan sank at its berth in Starrigavan Bay near Sitka, Alaska. The Powhatan initially sank in 15 meters of water, but later the tugboat slid further underwater and now rests in 60 meters of water. No reports of injuries, but some oil pollution was released.
Reports state the vessel had some 325 gallons of lube oil and 12 gallons of diesel fuel on board at the time of the sinking. The Coast Guard and local authorities were alerted and responded to the scene. Booms were placed on the surface to contain the pollution. An underwater camera will be deployed to monitor the vessel for any further release of pollution.
There are no reports if the vessel will be salvaged or not.
The 143 meter long, 17294 dwt cargo vessel Andesborg allided with a quay at Norrköping. Sweden. The Andesborg was attempting to berth at dock 2 of the Pampus Port when the aft section struck the quay. The cargo vessel sustained a hull puncture and ruptured a fuel tank. Some 1000 litres of diesel fuel spilled out into the port. Local authorities along with the Swedish Coast Guard responded to the scene. While the Coast Guard launched an environmental response team, the crew transferred fuel out of the damage tank and sealed the leak. Booms, absorbants and a vacuum truck had been deployed to recover the diesel fuel that was released into the water. No reports of injuries.
Reports state that strong winds has caused some difficulty, but the quick response to the incident reduced the impact of the spill. The incident is under investigation by the local police.
On April 7, the 112 foot long tanker-barge Vengeance was found capsized and later sunk in San Francisco Bay near Oakland, California. The barge was loaded with 4000 gallons of diesel fuel and 300 gallons of hydraulic oil sank in 50 feet of water between Treasure Island and Oakland near the Bay Bridge. No one was on board the vessel when it capsized. No reports of injuries.
A slick of diesel fuel was spotted on the surface over the wreck. Authorities deployed some 3,000 feet of boom to help contain the pollution. No official report on how much fuel had been released. Both state authorities and the Coast Guard are monitoring the site.
Divers were called to perform an inspection of the sunken tanker-barge and plug the fuel vents to impede any further release of diesel fuel or hydraulic fluid.
Local reports state the vessel may have capsized due to the high winds in the bay the night before. The Coast Guard has launched an investigation into the incident.
