The U.S. Coast Guard revised the Alternate Management Systems (AMS) Program for BW treatment systems by further extending the current five year
“extended compliance date” for ships fitted with an AMS. An installed AMS can be used for additional five years from the “extended compliance date” provided the AMS is installed prior to the expiration of the vessel’s extended compliance date. (For details, see http://mariners.coastguard.dodlive.mil/2016/07/12/7122016-alternate-management-systems-program-update-release-of-msib-10-16/.)
