Some of the largest diesel engines made are used at America’s ports. Roughly 2,000 establishments are engaged in deep water, coastal and inland water transportation – employing 73,000 individuals with a payroll of $2.8 billion.
Diesels are the driving force for almost all commercial water vessels and port operations. Examples include:
Regulations and Standards
ShipPort and vessel operators in the U.S. are regulated by both the Clean Air Act and Annex VI of the International Convention on the Prevention of Pollution from Ships (MARPOL). The MARPOL regulation sets limits on nitrogen oxide (NOx) and sulfur oxide emissions from ship exhausts, and the emission of ozone depleting substances. Additional regulations have been proposed by EPA.
Large manufacturers are already producing and designing engines to meet the strictest of environmental standards for marine vessels and port equipment. A number of clean diesel technologies, including cold-ironing (on-shore electrical plug-ins) and retrofitting yard equipment, are proving to be effective air quality solutions at American ports.

Water carriers move 563 million tons of freight each year-- worth $76 billion. Nearly all of the bulk carriers that transport oil, ore, wheat, and other goods are diesel powered, as are the containerships that transport the majority of all manufactured imports and exports.
There are no viable alternative power sources that provide the efficiency, fuel economy and power of diesel engines for these marine-based services.
