Congratulations to Cassidy Westin for receiving an OGS award for his PhD!
The research will focus on the development of an algorithm which could be implemented to predict instances of slack cable or detachment during marine towing operations. The algorithm will comprise a real-time “digital twin” of the cable system which will receive sensor data, simulate the corresponding cable behavior, and output critical information such as the cable tension or contact forces. The simulated output can then be used to alter the control signal to the winch to increase the cable tension and avoid potentially dangerous events. Additionally, the research will focus on the launch and recovery phase of towing operations, in which the likelihood of the cable slackening is highest.
