The Command Team Experimental Test-bed Stage 1:Design and build of a submarine command room simulator

The command room system has developed across a century of submarine operations and so reflects a high state of evolution, but that does not mean that the system cannot be improved upon. Technological advances have resulted in the retrospective fitting of upgrades which may not have maximized the potential improvements offered. Future challenges for command teams in almost every domain include increasing amounts of data coupled with more automated systems and reduced manning. To optimise functionality new physical layouts, team structures, allocation of system functions, communication media, interfaces, and work design will be required. The aim of the ComTET (Command Team Experimental Test-Bed) project is to examine how a submarine command team currently functions, with specific regard to how information flows around the socio-technical system. This information shall be used to evaluate limitations in the current system, promote ideas concerning where reduced crewing might be possible and highlight how extra data might best be integrated into the system. Phase 1 of ComTET involved the creation of a submarine command room with high physical and task fidelity. The ComTET team has designed and built a submarine command room simulator that is a representation of the currently operational ASTUTE submarine. The simulator is comprised of 10 workstations each with two stacked monitors, various input devices and a headset linked to a multi-channel communications network. The simulation engine is a custom build of Dangerous Waters software, a naval warfare simulation game. The software features many operator-controllable units from on board a submarine, allowing the completion of individual submariner command team tasks simultaneously to fulfil global (team) mission objectives. The ComTET laboratory has a range of devices for recording the personal communications of each operator, in addition to video recordings of each operator and ambient voice/video recordings. This will facilitate the construction of social, task and information networks to examine the command room from a socio-technical perspective. The laboratory is also equipped with physiological recording devices so that the workload of operatives can be examined using psycho-physiological approaches alongside commonly used standardised measures of workload, situation awareness and cognitive function. The data collected shall be based around three scenarios which capture the primary operations routinely completed by submariners in high and low work load conditions. © 2015 The Authors.
