[en] The term autonomous and unmanned ship comprises many different approaches having advantages and disadvantages depending on the point of view adopted. Some studies written about the topic show few applications that are in operation nowadays. Most of all are smallunmanned surface vessels collecting data and performing hazardous tasks in a variety of difficult areas to access. Moreover, there are several potential local applications for unmanned navigation such as dredging, firefighter crafts, tugboats, fishing vessels, ferries, skimmer boats and even fully autonomous submarines. On the one hand, we have stakeholders who are putting a lot of effort to make it real and they state that we are ready to go to the next level; however, on the other hand, some are sceptical about crewless ships and how they will affect the marine industry. Overall, this study go through technical, regulatory and economical challenges regarding the possibilities for using an unmanned vessel to emulate the current ship operational mode and somehow improve the whole process to convince the stakeholders to put their money on it. The outcome intended to become a solid material for further discussions to make unmanned operation a reality.
