The development of the “Sea Traffic Management” (STM) concept and its “Port Collaborative Decision Making” (PortCDM) enabler in the MONALISA and STM validation projects aimed to improve safety and efficiency of maritime transport.

Within STM, a Port Call Message Format has been developed to enable the coordination of stakeholder activities associated with port calls by providing a standard format to share the necessary information, particular time stamps, associated to movements and operations during port call operations.

In order to ensure sustainability and interoperability with the IMO initiative “e-Navigation”, the International PortCDM Council (IPCDMC), initiated in the STM Validation project, has supported the idea to migrate the Port Call Message Format into a Common Maritime Data Structure (CMDS) format and as such integrate it in the CMDS GI Registry currently managed by the International Hydrographic Office (IHO). IALA has assigned S-211 within the IALA VTS domain as the identifier for this standard.



S-211 has been validated, been accepted and is now fully registered in the IHO GI Registry. It is part of the IALA VTS domain within the CMDS GI Registry.

This standard enables both the merchandise fleet, as well as other types of ships, and the ports of the world to exchange port call data in a standardized manner to enable enhanced coordination and synchronization of port visits,

...the International PortCDM Council said.

The MONALISA project with a consortium of 7 partners and a budget of 22 million euro, lasted 2010-2013 and demonstrated routeplanning and route sharing, which is the forebearer of STM.

MONALISA was the winner of the 2017 SMART4SEA Innovation Award for introducing smart solutions and sharing information data resulting in efficient, safe and environmentally friendly maritime transport while reducing administrative burdens.
