Global maritime traffic is increasing, and the development of Maritime Autonomous Surface Ships (MASS) is progressing. Demonstrations have been carried out, and the first fully autonomous voyage under human supervision was completed in Norway in 2023. The International Maritime Organization (IMO) is developing regulations for the introduction of MASS and aims to issue a mandatory MASS Code in 2032. Research is being conducted on the actual management of engine plants and maintenance methods for the realization of MASS, but research on how to safely operate and manage ships is still lacking. The aim of this paper is to capture an overview of the changes in ship management with the advent of MASS by means of a questionnaire survey of seafarers in ocean shipping companies. Cooperation was obtained from 100 captains and deck officers to clarify this objective. Regarding the items studied, an analysis is made of the expected changes in ship management and how they are expected to change in the future.
