Several prototypes of autonomous ships have been developed over the last decade. Although Norway is a pioneer in the technological development of autonomous ships, other countries such as China, Finland and the US have also made significant progress. However, future applications of autonomous ships and potential business models are still not well researched. Autonomous ships are expected to be commercially launched in the future, adding a new dimension to the merchant shipping industry. Therefore, this graduation seminar is based on the conceptualization itself, ie it touches on the main questions: What? When? How? Why?. It also provides an overview of development projects and the benefits of autonomous ships from an economic, environmental and social perspective, suggesting the innovative use of autonomous ships in inland sea shipping as well as conventional shipping, and finally concludes whether it is worthwhile to embark on such a risky venture despite the many benefits it brings us.
