Abstract
Vertical plane response of submersible vehicles in the proximity of a free surface in both deep and shallow waters is evaluated using a potential flow, strip theory solver. Three criteria, namely periscope submergence, sail broaching, and collision are used to quantify the response. These criteria combined with the vehicle's response amplitude operators in regular sinusoidal waves along with a statistical description of the seaway lead to an assessment of an overall operability index for the vehicle. The operability index is calculated within a given range for sea states and sea directions and for various vehicle speeds and operating depths. The results indicate that a certain combination of depth and speed can lead to a significant improvement in vehicle operations.
