Determinants of Ship Accident Seaworthiness

This study investigates determinants of the seaworthiness of ships involved in accidents, utilizing detailed data of individual tanker, container and bulk ship (U.S. and foreign) accidents investigated by the U.S. Coast Guard. Ordered probit estimation results suggest that ship accident seaworthiness: 1) increases with ship size; 2) is greater if the ship is classified by the American Bureau of Shipping and manned by a licensed operator; and 3) is less for a tanker ship, for multi-ship accidents, at higher winds, if the weather is foggy, and for collision, fire/explosion and material/equipment failure accidents than for groundings. Estimated marginal ship accident seaworthiness probabilities suggest that policies that reduce fire/explosion and material/equipment failure accidents and increase the manning of ships by licensed operators are likely to be efficacious in improving ship accident seaworthiness.
