The effect of high speed vessel operations on ship's crew and embarked personnel aboard HSV-2 SWIFT in the areas of motion sickness and motion induced task interruptions

摘要

The Navy's use of high speed vessels such as HSV-2 SWIFT has raised questions of the effects of high speed motion on the ability of personnel to perform assigned duties. Performance degradation may occur during periods of excessive ship motion because of extreme motion sickness or periods of frequent task interruptions. With the use of high speed vessels expected to increase in the near future with the Littoral Combat Ship program, the issue of high speed motion effects on personnel becomes operationally relevant. This study will take a two part approach to analyze the effects of high speed motion: the motion sickness of SWIFT's crew and military passengers, and interruptions of task performance caused by vessel motion to critical watch stations. For the first part, statistical analysis will be used to determine relationships between ship motion and motion sickness. For the second part, modeling and simulation will be used to determine if there are watch stations that may be affected by varying levels of motion induced task interruptions. From this analysis, guidelines may be produced to describe the expected levels of motion sickness in personnel as well as watch stations in which personnel may have difficulties performing assigned duties.
