But the Seattle-based company in the hottest seat right now may be Coffman Engineers, which allegedly failed to detect any problems with BP’s Prudhoe maintenance in a report to the state of Alaska a couple years ago. Coffman’s now been subpoenaed by the Feds in their ongoing investigation of alleged malfeasances at Prudhoe Bay.
