Classification Society ClassNK has granted approval in principle (AiP) to NYK Line and MTI Co for their joint project on the concept design of an autonomous ship framework developed under the name APExS
Action Planning and Execution System (APExS) is a framework designed to use Maritime Autonomous Surface Ships (MASS) technology which includes high-speed computer-based information processing technology and risk analyses that support crew members’ situational awareness and the decision-making necessary for autonomous manoeuvring.
The certification marks the first time an autonomous ship framework has won approval in Japan. ClassNK reviewed the safety of the framework and certified the concept design on 20 February. Based on this framework, NYK said it will further deepen its co-operation with domestic and overseas partners to develop autonomous ship technology that contributes to advanced safe operation.
ClassNK is involved in demonstration projects and works to develop safety standards to support the development and implementation of automated operation technologies. In January 2020, the society published its Guidelines for Automated/Autonomous Operation of ships which summarises the requirements for each stage of conceptual design, design development, installation, and maintenance during the operation of automated operation technologies.
Jointly with NYK Line and MTI, ClassNK verified the safety of system usage conditions, fall-back systems, and other elements for the development of the autonomous ship framework. The society said the AiP was granted after confirming the feasibility of the framework through safety evaluation in line with the its guidelines.
In addition to this, IMO is working on autonomous ship trial guidelines.
