Section 3717 requires the Secretary to establish a marine safety information system which is to contain selected information on any tank vessel, foreign or domestic, that comes within the jurisdiction of the United States. This information must be recorded and maintained up-to-date and is available from a number of sources. In some instances, this information is required as a condition of entry. This information shall include certain ownership interests, financial responsibility information, all registered names that the vessel has had since it was built, the present and prior countries of registry, history of accidents or serious repair problems, record of the various inspections or examinations required, and any other data the Secretary deems appropriate to carry out the intent of the section. The section also provides for interagency cooperation and the furnishing of available data and information.
