Autonomous ships are unmanned vessels without or with a small number of passages. An autonomous ship is a ship that has levels of automation and self-management. The purpose of developing autonomy is to replace human action, which should be faster, safer, more precise, more productive and / or cheaper. In the future, autonomous ships should operate without a crew and the advantage of this is the reduction or complete exclusion of the human factor from accidents. The vast majority of traffic accidents happen precisely because of human error. Autonomous ships operated remotely from the control center must be well equipped with devices and sensors that will be able to give the operator a sense and image of the environment. For that purpose, the most necessary devices are: cameras, radars and Lidar. In addition to the image of the environment, the ship with the control center must have strong and secure communication. These communications can be via satellite (Inmarsat, Iridium), and terrestrial or land communications (MF / HF radio, VHF radio, 4G and 5G networks). MASS is often mistaken for a synonym for unmanned ships. While it can be unmanned, it can also have maintenance staff or even navigators. Whether or not an autonomous ship has a crew, it is operated by an operator from the control center. That raises a lot of questions. Will the operator be able to actively monitor more ships and will it be able to react in time in case the automation fails? Who will maintain the ship? Human factor problems? What can all be human errors that can affect human-machine and human-human interaction during remote ship operations?
