Abstract
DRDC has an interest in understanding the structural capability of its vessels when deployed in high latitude environments with potential for ice impact loading on the hull structure in the marginal ice zone. The vessel being considered here is a concept referred to as the Notional Destroyer, and has characteristics similar to many naval patrol/frigate/destroyer class vessels with a hull structure that is not strengthened for ice impact. This report, while building on prior techniques, includes new approaches for the direct analysis of structural capability under ice loads. These new analysis approaches have been tailored for application to non-ice strengthened vessels such as naval vessels.
