SUMMARY:Estimation of marine incidents and oil spills: counts and probabil
 ities for coastal waters of US and Canada
DESCRIPTION:Paper\n\nVasile-Alexandru Suchar, JD Ross Leahy, Alex Hess, Ja
 mes Murphy, and Adam Byrd (Washington Department of Ecology)\n\nTo evaluat
 e the likelihood of marine incidents, the United States Coast Guard (USCG)
  Marine Information for Safety and Law Enforcement (MISLE) and Transportat
 ion Safety Board of Canada's Marine Safety Information System (MARSIS) inc
 ident databases were analyzed to identify and count observed incidents fro
 m 2002 to 2019. Vessel types for hazard probabilities were categorized, an
 d due to a limited number of observed incidents, some vessel types were co
 nsolidated as such: tank ship, tank barge and articulated tug and barge (A
 TB), passenger ship, container ship, general cargo ship, bulk carrier, and
  large fishing vessel. Seven hazard categories were considered: allision, 
 capsize/sinking, collision, loss of propulsion, loss of steering, groundin
 g, and other. The process involved mapping MISLE and MARSIS incident and v
 essel categories to our selected categorizations. Automated text processin
 g was necessary to extract relevant information from the incident summarie
 s in the databases.  The research indicated that, marine incidents are rar
 e events and oil spills from marine incidents are even rarer. There were 3
 2,779 incidents from 2002 to 2019 in the bi-national area (United States a
 nd Canada). Of these, over 65% were categorized as loss of propulsion, los
 s of steering, and other. Excluding the hazard type category “other”, coll
 isions were the largest contributor to oil spills. A formal validation was
  hindered by the scarcity of hazard probabilities in the existing literatu
 re.\n\nTag: Preparedness\n\nSession Chair: Jereme Altendorf (US Coast Guar
