Disabled submarine (DISSUB) escape time calculations: A comparison of time and accuracy between the 2006 and 2020 Disabled Submarine Survival Guides
Abstract
During a disabled submarine (DISSUB) scenario, crew members must refer to the Disabled Submarine Survival Guide (also known as the Guard Book) to determine appropriate procedures for survival, including calculations for escape times. A pressing concern is that these critical calculations can be difficult to complete. In an attempt to address this issue, the method for completing escape time calculations has been revised in a new edition of the Guard Book. In the present study, thirty-four subjects completed both the older (2006) and revised (2020) versions of the Guard Book carbon dioxide and oxygen escape time calculations. Accuracy was low and did not significantly differ between versions (38.24% for the 2006 version vs. 41.18% for the 2020 version). Participants were significantly faster when completing the 2006 version and 50% of participants preferred the 2006 version over the 2020 version. The two calculation methods elicited different error types. Mathematical and instructional errors were most frequent for the 2006 version, inaccurate rounding on lookup tables and time conversion errors were most frequent for the 2020 version. We provide recommendations for reducing errors that emerged in the 2020 version thereby increasing the chance of survival in DISSUB scenario.
