交通部拟数十年来首次更新液化天然气设施标准：新技术写入规则，预计每年节省约1亿美元
美国交通部10月28日在 Houston 宣布，管道与危险材料安全管理局（PHMSA）已发布拟议规则通知（NPRM），数十年来首次更新液化天然气（LNG）设施标准：新规把管中管系统、单壁 ASME 容器和膜式储罐等现代技术写入规则，并纳入美国消防协会 NFPA 59A（2026年版）作为设施选址、设计、建造、运营与维护的框架，交通部预计采用这些技术每年可节省约1亿美元。
交通部表示，此次更新意在加快新的 LNG 基础设施项目、降低能源成本、扩大出口能力。按拟议规则，运营商可以顺畅采用上述节本增效技术，在提升安全的同时减少过时条文造成的延误。拟议规则全文将刊登在《联邦公报》。
交通部长 Sean P. Duffy 说：「美国拥有自然资源、创新精神和私营部门的力量，足以成为世界第一能源强国。唯一挡路的是过时的繁文缛节。通过改革这些基本规则、拥抱现代技术，我们可以安全地释放美国的能源主导地位、降低成本。」
管道与危险材料安全管理局局长 Paul Roberti 表示，作为全球最大的 LNG 出口国，美国的 LNG 设施法规是行业金标准，但这些规则已经停滞，仍依赖一个20多年前的行业标准版本；此次提案承认过去十年行业创新的变化，通过精简监管要求、激励前沿技术部署来提升安全。此前在2025年4月，交通部已先行发布预先拟议规则通知（ANPRM），就更新这套数十年旧规征求意见，本次 NPRM 是该进程的下一步。
DOT Proposes First Update to LNG Facility Standards in Decades: New Technologies Codified, About $100 Million in Annual Savings Expected
The U.S. Department of Transportation announced in Houston on October 28 that the Pipeline and Hazardous Materials Safety Administration (PHMSA) has published a Notice of Proposed Rulemaking (NPRM) to update liquefied natural gas (LNG) standards for the first time in decades. The proposal codifies advanced, cost-saving technologies, including pipe-in-pipe systems, single-walled ASME containers, and membrane storage tanks, and incorporates National Fire Protection Association (NFPA) Standard 59A (2026 edition) for the siting, design, construction, operation, and maintenance of LNG facilities. The Department said leveraging these technologies will generate $100 million in savings annually.
The Department said the update will fast-track new LNG infrastructure projects, lower energy costs, and expand export capacity. The full text of the NPRM will be posted in the Federal Register.
"America has the natural resources, innovative spirit, and private sector might to be the world's number one energy powerhouse. The only thing standing in our way is outdated red tape," said U.S. Transportation Secretary Sean P. Duffy. "By overhauling these basic rules to embrace modern technologies, we can safely unleash America's energy dominance, lower costs, and generate millions in economic opportunity for the men and women powering our energy sector."
"As the world's largest LNG exporter, the United States' regulations for LNG facilities are the gold standard," said PHMSA Administrator Paul Roberti. "But we have let those regulations stagnate, relying on an outdated version of an industry standard from more than twenty years ago. Today's long overdue proposal recognizes the innovation that has transformed the industry over the last ten years and enhances safety by streamlining regulatory requirements and incentivizing the deployment of cutting-edge technologies." In April 2025, the Department had issued an Advance Notice of Proposed Rulemaking (ANPRM) to inform this rulemaking proposal to update the decades-old LNG facility regulations.
