Understanding MASS: Beyond the Label of “Autonomous Ships”

Cosa distingue davvero una nave autonoma (MASS) da una nave altamente automatizzata? Partendo dalle definizioni del nuovo Codice IMO, questo articolo chiarisce i concetti di Operational Envelope, degraded state, e i rischi degli “unknown unknowns”. Scoprirai perché l’autonomia non elimina l’umano, ma lo sposta, richiedendo competenze digitali, critiche e marittime completamente nuove.

Safety Assurance for Autonomous Vessels: An Accessible Explanation

Autonomous and remotely operated ships challenge traditional maritime safety frameworks by removing the crew from the ship and transferring safety responsibilities to systems, software, and shore-based operators. To obtain regulatory approval under IMO MSC.1/Circ.1455, autonomous vessels must demonstrate a level of safety equivalent to that of conventional ships.
This article provides an accessible explanation of an integrated safety assurance methodology based on Model-Based Systems Engineering (MBSE), System-Theoretic Process Analysis (STPA), conventional risk analysis, and simulation-based verification. Using a real autonomous ship development project as reference, it illustrates how safety goals can be systematically decomposed, verified, and traced throughout the system lifecycle, offering a practical framework for safety equivalence demonstration in Maritime Autonomous Surface Ships (MASS).
