To authorize issuance of certificates of documentation authorizing certain vessels to engage in coastwise trade in the carriage of natural gas, and for other purposes.

H.R. 6524 is a bill that would grant specific legal exemptions to three liquefied natural gas (LNG) tankers—the LNG Gemini, LNG Leo, and LNG Virgo—allowing them to transport natural gas between U.S. ports. Under a long-standing federal law known as the Jones Act, only ships built, owned, and flagged in the United States are typically permitted to engage in this type of domestic trade. By providing these vessels with "coastwise endorsements," the bill aims to increase the available shipping capacity for moving natural gas within the country, potentially impacting domestic energy distribution and logistics.
