Decision Support System (Bridge)

Bridge software that assembles navigation, traffic, and environmental data into advisories for collision avoidance, route monitoring, and grounding prevention, presented through ECDIS and radar/ARPA. It draws on COLREG-aware target tracking, ENC depth contours, and predicted under-keel clearance. IMO has no single performance standard for an integrated DSS; relevant standards include ECDIS (IMO MSC.232(82)), radar (MSC.192(79)), and bridge alert management (MSC.302(87)). The output remains advisory; the watchkeeping officer retains the conning decision under SOLAS V.
