Ship Operation

The advent of artificial intelligence and deep learning has provided sophisticated functionality for sensor fusion and object detection and classification which have accelerated the development of highly automated and autonomous ships as well as decision support systems for maritime navigation. It is, however, challenging to assess how the implementation of these systems affects the safety of ship operation. We propose to utilize marine training simulators to conduct controlled, repeated experiments allowing us to compare and assess how functionality for autonomous navigation and decision support affects navigation performance and safety. However, although marine training simulators are realistic to human navigators, it cannot be assumed that the simulators are sufficiently realistic for testing the object detection and classification functionality, and hence this functionality cannot be directly implemented in the simulators. We propose to overcome this challenge by utilizing Cycle-Consistent Adversarial Networks (Cycle-GANs) to transform the simulator data before object detection and classification is performed. Once object detection and classification are completed, the result is transferred back to the simulator environment. Based on this result, decision support functionality with realistic accuracy and robustness can be presented and autonomous ships can make decisions and navigate in the simulator environment.

This study draws attention to the very large number of British merchant vessels, and their crews, which traded or acted as supply vessels through to the end of the Second World War, in contrast to those which succumbed to enemy action. Normal commercial trading between Western Australia and Java/Malaya until the fall of Singapore is contrasted with military supply ship operation between Eastern Australia and New Guinea. This is set in the context of trading before the war, and the developing political scene in south east Asia. The ships’ crews, the dangers faced, protective measures, and cargoes, including human cargoes, are considered. With one vessel surviving the war unscathed, another continuing service after war damage and repair, and one torpedoed and sunk, the article concludes that the examples fully represent the experiences of the mass of merchant shipping which ended the war in the western Pacific military supply chain.
