This project is a collaboration with Australian Maritime College (UTAS) and the CSIRO CI team to design a system to aid the navigation of large vessels as they enter or leave a port.
The overall objective of the project is to identify mechanisms for managing vessels in port waters that will improve productivity, occupational health and safety (OHS), and operations from a safety point of view.
Our focus in this project is:
Given the safety-critical nature of operations on a large ocean going vessel, and considering the need to understand operator workload for individuals in the distributed maritime operations team (including Captain, Pilot, Tug Master(s), and Vessel Traffic Service), we have begun investigating the remote collection of Electro-Dermal Activity (also known as Galvanic Skin Response) as a correlate of mental workload. Electrophysiological signals are collected via personal radio transmitters for each team member, and these measures are combined with more traditional methodology (Instantaneous Situation Awareness measure; Subjective Workload Assessment Technique; Communications Analysis) in order to develop an understanding of the mental state of each team member during both standard operation conditions, and during critical emergency events such as engine failure, steering failure, and communications failure.
Some example data from our latest full scale-simulation run with specialists from an Australian port authority in the AMC sim follow.

Communications that were not specifically for the Captain or Pilot were labeled ‘Bridge’. If the pilot had an order for both tugs, this was labelled ‘Both Tugs’, as opposed to individual tug orders (Keera, Marysvale).
