foreign-flagged vessel examinations were limited to
ensuring that these vessels complied with domestic laws
and regulations. In 1994, the Coast Guard developed a
more robust port state control program to eliminate sub-
standard foreign-fagged vessels from calling on U.S.
Because foreign-fagged MODUs seldom call on
U.S. ports, they are not always subject to U.S. port state
control. By engaging in seabed activities on the OCS,
they typically fall under coastal state authority.
In accordance with the IMO Code for the Construction
and Equipment of Mobile Offshore Drilling Units, 2009
(MODU Code), a coastal state is defned as the govern-
ment of the state exercising administrative control over
the drilling operations of the unit. The Coast Guard
administers U.S. OCS coastal state authorities through
OCSLA statutory authority. This is the authority the
Coast Guard most often exercises over foreign-fagged
