FREDYN Simulations of HALIFAX for Determining Helicopter Securing Loads

Abstract

In support of procurement of new maritime helicopters, DRDC Atlantic was tasked to simulate motions of the HALIFAX class in seaways. The data produced will aid in the determination of helicopter securing loads, which are highly dependent upon the motions of the ship. The present work reports a systematic series of simulations modelling a HALIFAX class frigate with nominally steady speed and heading (course-keeping) in a variety of seaway conditions. This memorandum provides the explanation of the procedure used as well as the key results. A companion report (DRDC TM 2004044)contains tabulated results from the simulations.
