An Investigation of the Relative Motions of ACV Landing Craft and Large Amphibious Assault Ships

摘要

A mathematical analysis is used to determine the relative motions between an ACV landing craft and different assault ships under operating modes corresponding to well entry and alongside conditions associated with cargo transfer. The technique used is based on linear equations of motion, with probabilities of transfer determined from response data obtained via spectral analysis methods. The results provide guidance vs best operating speed of the assault ship and of the ACV; preferred heading relative to the waves; best orientation and position of the ACV relative to the assault ship; and limiting sea state conditions for safe and/or best operations to occur.
