Each Code of Federal Regulation (CFR) cited below is updated annually in a free searchable database available from GPO Access.
The mechanical engineering technical section provides for regulatory and standards development in the more traditional areas of marine engineering systems such as boilers & pressure vessels, hoses & piping, and turbines & engines as well as specialized systems such as marine sanitation devices, pollution prevention equipment, and resiliently seated valves.
Marine engineering regulations in 46 CFR Subchapter F provide for the specifications, standards, and requirements for strength and adequacy of design, construction, installation, inspection, and testing for vessel machinery, boilers, pressure vessels, safety valves, and piping systems.
Marine Sanitation Device (MSD) regulations in 33 CFR Part 159 provide for the design, construction, and certification of equipment that eliminate the discharge of untreated sewage from vessels into the waters of the United States. More information is available on our Marine Sanitation Device page.
Pollution Prevention Equipment (PPE) regulations in 46 CFR 162.050 provide for the design, construction, and certification of oily water separators, cargo monitors, bilge monitors, and bilge alarms for vessels. More information is available on our Pollution Prevention Equipment page.
Resiliently Seated Valve (RSV) regulations in 46 CFR 56.20 provide for the design, construction, and certification of RSVs where closure is accomplished by resilient nonmetallic materials instead of a metal to metal seat. More information is available on our Resiliently Seated Valve page.
