Researcher Colin Grabow identified at least 15 Jones Act waiver energy voyages not listed in official US MARAD data, according to a report filed Sept. 21.[^2] The temporary waiver is scheduled to expire in November 2026.[^3]

MARAD stated it lacks legal authority to compel operators to report Jones Act waiver voyages.[^4] The unreported voyages delivered energy to Hawaii, California, Puerto Rico, Pennsylvania and Connecticut.[^5]

Grabow argues the findings justify permanent Jones Act reform.[^1] The Jones Act requires ships moving freight between US ports to be US-built, at least 75% US citizen crewed and 75% US citizen owned.[^6] Construction costs run about three times foreign levels and operating costs at least twice as much.[^7]
