46 CFR 15.715: Manning credit for automated vessel systems

Last reviewed: October 14, 2026

This section covers Coast Guard acceptance of automated systems that replace specific personnel or reduce overall crew requirements. Acceptance depends on the system's capabilities, its reliability, and a planned maintenance program. Until a system is proven reliable, the COI specifies a manning level adequate for continuously attended operation.

What it says

  1. Coast Guard acceptance of an automated system to replace specific personnel or reduce overall crew requirements is predicated upon the system's capabilities, its demonstrated and continuing reliability, and a planned maintenance program.

Common questions

What does the Coast Guard consider before accepting an automated system to reduce crew?

Acceptance depends on the system's capabilities, its demonstrated and continuing reliability, and a planned maintenance program that ensures continued safe operation of the vessel.

“the system's demonstrated and continuing reliability, and a planned maintenance program that ensures continued safe operation of the vessel”

What manning level goes on the COI before an automated system is proven reliable?

A manning level adequate to operate in a continuously attended mode will be specified on the vessel's COI until the system is proven reliable.

“until the system is proven reliable, a manning level adequate to operate in a continuously attended mode will be specified on a vessel's COI”

Who decides when a continuous watch is necessary on an automated vessel?

The vessel's Master remains responsible for deciding when a continuous watch is necessary.

“It remains the responsibility of the vessel's Master to determine when a continuous watch is necessary.”

Automated vessels

(a) Coast Guard acceptance of automated systems to replace specific personnel or to reduce overall crew requirements is predicated upon the capabilities of the system, the system's demonstrated and continuing reliability, and a planned maintenance program that ensures continued safe operation of the vessel.

(b) The OCMI considers the capabilities of an automated system in establishing initial manning levels; however, until the system is proven reliable, a manning level adequate to operate in a continuously attended mode will be specified on a vessel's COI. It remains the responsibility of the vessel's Master to determine when a continuous watch is necessary.
