The mission of the NIMASA Maritime Domain is to provide global maritime geospatial intelligence in support of national security objectives including safety of navigation, international obligations, intelligence activities and joint military operations. Navigational warnings are issued in response to SOLAS regulation V/4 and carry information which may have a direct bearing on the safety of life at sea. It is the fundamental nature of navigational warnings that they will often be based on incomplete or unconfirmed information and mariners will need to take this into account when deciding what reliance to place on the information contained therein. In order to achieve the necessary impact on the NIMASA MSI Portal will present timely and relevant information in a consistent format that is CLEAR, UNAMBIGUOUS and BRIEF. This is ensured by using structured messages in standard formats as you will see in our Navigation warnings and Meteorological forecast on our secure portal.
