BOX 2-1 Marine Operations Bridge Simulators Classifications Proposed to International Maritime Organization (IMO)
Within the marine industry, the terminology used to describe or classify simulators varies greatly. The terminology used in this report has been proposed for adoption by the IMO.
Category I: Full mission. Capable of simulating full visual navigation bridge operations, including capability for advanced maneuvering and pilotage training in restricted waterways.
Category II: Multi-task. Capable of simulating full visual navigation bridge operations, as in Category I, but excluding the capability for advanced restricted-water maneuvering.
Category III: Limited task. Capable of simulating, for example, an environment for limited (instrument or blind) navigation and collision avoidance.
Category IV: Special task. Capable of simulating particular bridge instruments, or limited navigation maneuvering scenarios, but with the operator located outside the environment (e.g., a desktop simulator using computer graphics to simulate a bird's-eye view of the operating area).
