The following list represents those Ship Management entities (owners, and operators) that are participating in the "Large Fleet" designation. Ship Management entities that have 25 or more individual vessels in their fleet, in which each one of those vessels have made at least one arrival within the past 12 months to the United States, are eligible to participate in this program. A single vessel making multiple arrivals in the U.S. over the course of a year does not constitute multiple distinct arrivals. Only a single distinct arrival can be credited per individual vessel, per year. Members participating in the "Large Fleet" program are entitled to additional detention(s) before being targeted by the U.S. for Port State Control. This means that if a Large Fleet participant has been associated with 3 or more detentions¹ (depending on size of fleet * see chart below) within a 12 month period, then that Ship Management entity will be targeted.

"Large Fleet" entities can participate in the program for 12 months, and then must reapply for each 12 month period thereafter. Applications for renewal into the Large Fleet program must be filed within thirty (30) days prior to expiry, in order to avoid a lapse in enrollment. Organizations who feel that they qualify for eligibility to participate in this program may apply² directly to the following email address PortStateControl@uscg.mil. Faxed applications will no longer be accepted. When applying, applicants must state that the purpose of the e-mail is to apply for the Coast Guard's "Large Fleet" designation and use the Large Fleet Template.

As of July 1, 2010, the below detention figures that will trigger a Ship Management entity to be targeted, are as follows:
