Development of a Heavy Weather Operator Guidance Catalog for FF-1052 Class Ships

摘要

This report is the second in a series that considers the inclusion of seakeeping data in ship operations planning and decision making. It presents a condensed version of a Catalog of Heavy Weather Operator Guidance (HWOG) developed for FF-1052 Class ships. The Catalog provides the ship operator with hard copy, quantitative predictions as to how the ship responds in a seaway and some guidance for avoiding excessive ship motions or related events, such as slamming and wetness, that may cause damage to the ship during heavy weather conditions. The Catalog makes no attempt to tell the operator what to do, but rather describes, through seakeeping operator envelopes (SOE's), what he may expect under a set of arbitrary sea conditions. It is intended that the application of the provided data should be made with good judgement, the consideration of mission requirements, and the operator's firsthand interpretation of prevailing conditions. In addition to presenting a condensed version of the HWOG Catalog, this report also briefly describes the analytic procedures used and the assumptions made in the development of this Catalog, which, it should be noted, are the result of the cooperative efforts of the design, R&D, and operations communities.
