In Norway a 120 TEU container feeder is being build and will start sailing autonomously in 2022. The challenge is huge. One question is whether or not the present, quantitative, collision regulations needs to be updated to rules where expressions as searly” and ssubstantial” are quantified? Or if ships can sail autonomously under the present rules? Another question is if MASS should be marked to signal that the ship is in autonomous mode? Or if it is enough that she follows COLREGS? This discussion paper will take a closer look at these questions and advocate automation transparency, meaning that the behavior of an autonomous vessel has to make sense and be understandable to human operators on other manned ships and crafts.}, doi = {10.12716/1001.13.03.04}, issn = {2083-6473}, publisher = {Gdynia Maritime University, Faculty of Navigation}, keywords = {Maritime Autonomous Surface Ships (MASS), Colregs, Collision Avoidance, Ordinary Practice of Seamen, Officer of the Watch (OOW), Shore Control Centre (SCC), Operational Design Domain (ODD), Anti-Collision} }
