A Marine GIS-based Alert System to Prevent Vessels Collision with Offshore Platforms

How to effectively use an intelligent aid-to-navigation (AtoN) prevent ships from accidentally colliding with offshore marine platforms (OMPs) is important issue for maritime environment. This study proposes a novel collision alert system three components process Automatic Identification System (AIS) data in the cloud and broadcast AtoNs order avoid OMPs. The first component receives as input fuzzy linguistic variables (vessel size, relative speed, approach distance) AIS calculates radius of guarding ring. second serves Marine GIS (MGIS), where simulates based on ring at one levels: green (continuous light), amber (slow flash alarm), red (flash fast alarm). third warning indicator device, signaling risk between moving platforms. MGIS can also be used OMP approaching warn platform workers vessel traffic service (VTS) on-duty operators. ability proposed protect OMPs collisions has been verified. Other potential applications include wind turbines, oil rigs, or other working
