Technological development related to Maritime Autonomous Surface Ships (MASS) is progressing worldwide, and international rule-making activities are also underway. However, there has not yet been sufficient discussion on the requirements for sensors that can replace the watchkeeping duties of seafarers as required by laws and regulations, and on factors that can cause disturbances to recognition. This paper provides consideration on the sensor requirement specifications for autonomous ships based on ship accident data analysis. Depending on the size of the ship, it may be necessary to recognize objects located at a great distance. Therefore, rather than requiring hardware that can acquire data of a quality that allows feature extraction and recognition from the stage of discovering the object, it is also necessary to have software requirements that can gradually recognize detected objects. In addition, a framework is also needed that can identify the targets of OEDR and individually consider the sensor requirements.
