Maritime autonomous surface ships (MASS) represent a critical direction for the development of current maritime industry. Their health development requires support from a comprehensive equipment system. Aligned with the International Maritime Organization’s Maritime Autonomous Surface Ships Code framework, this study focuses on the implementation of remotely operated vessels with autonomous capabilities. Through systematic analysis of the technological requirements for autonomous marine equipment, this study investigates the establishment of an overall architectural framework, a supporting equipment system, and processes for autonomy design and level evaluations. The key points and recommendations for the research and development of onboard autonomous functional systems and digital-intelligent equipment are proposed. It provides a systematic framework for the commercial application of autonomous ship equipment.
