Exxon Shipping Company

The Exxon Valdez grounding became an environmental-accountability test because control was distributed long before oil reached the shore. Exxon Shipping Company controlled master fitness, manning, watchkeeping expectations and the vessel's bridge; public authorities controlled pilotage, vessel-traffic oversight and legal safeguards; Alyeska, Exxon, Alaska and federal responders controlled different parts of a contingency system; and trustees, courts and regulators later controlled how injury, compensation, restoration and reform would be proved. The durable lesson is not that one mistaken turn caused every consequence. It is that a high-consequence transport system must make prevention, response capacity, worker protection, ecological evidence and remedy independently verifiable before a casualty exposes their interfaces.
