LOMA 1.0, the initial operational capability of the Lock Operations Management Application, became operational effective 31 March 2011. LOMA is currently in place at 12 lock and dam locations: Bonneville on the Columbia River; Cannelton on the Ohio River and Lock 22 on the Upper Mississippi River; and Howell Heflin, Tom Bevill, John C. Stennis, Aberdeen, Amory, Glover Wilkins, Fulton, G.V. Montgomery and Jamie Whitten Locks on the Tennessee-Tombigbee Waterway.
LOMA provides lock operators with greatly increased situational awareness of vessels operating in the vicinity of their locks. Using the Automatic Identification System (AIS) – a navigation safety technology similar to a transponder mandated on many commercial vessels- LOMA automatically collects vessel navigation information, including real-time location, direction, speed and identification. This information is presented to the lock operator through a web-based user interface integrated with other operational information, including electronic navigation charts (ENC), weather and lock status. Lock operators can set up zones to alert them when vessels enter the area, as well as annotate their display with markers. Lock operators can send messages to vessels for use in navigation safety, and these messages can be set to be transmitted automatically when a vessel enters a designated zone.
