§3106 Master Key Control System

Summary

Owners of vessels that must be inspected under section 3301 must have a master-key control system, either manual or electronic, that limits who can use any copy of the vessel’s master key. The owner must keep a list, by crew position, of who may use the key and keep that list on the ship, in owner records, and in the vessel safety management system. Every time the key is used the ship must log the date and time, the room or location opened, and the name and rank of the crew member. The log can be electronic and must be kept in one central spot that law enforcement can access. The list and log must be given to an FBI agent, a Coast Guard member, or other law enforcement officer on request during an investigation. Crew not on the list may not use the master key except in an emergency, and if they do they must tell the master and owner right away. A crew member who uses the key without permission can be fined up to $1,000 by the United States and may face suspension or revocation under section 7703. This rule does not apply to vessels covered by section 3507(f).
