Shareholders sue BP over Prudhoe Bay maintenance

Senior executives at BP face a lawsuit filed by shareholders who claim the oil giant’s poor maintenance practices at Prudhoe Bay led to the partial shutdown of the nation’s largest oil field.

The suit alleges that BP has known for years about the severe pipeline corrosion that led to last week’s shutdown, but took no substantial steps to properly monitor and repair the transit lines that ferry oil straight into the 800-mile trans-Alaska pipeline
