Many state and local air pollution control agencies are considering rules that would require recovery of vapors from marine loading operations to help meet EPA-mandated ozone level regulations. Most of the proposed rules will require recovery of vapors from crude oil and gasoline loadings. Several marine vapor recovery systems designed for dedicated ships in a dedicated trade have been operated successfully over the past few years, but a universal system has yet to be designed. This paper describes the basic principles of vapor recovery systems as they pertain to inerted tankers. The Gaviota Marine Terminal Vapor Recovery System and other marine systems are briefly described. Complications caused by the impending local or national vapor recovery rules and remaining safety concerns are also discussed.
