M Redmond: 2417. SWATH Weight Engineering – A Case Study. 1998.



Small Waterplane Area Twin Hull (SWATH) ships present a unique challenge to naval architects and weight engineers. While SWATHs are surface ships, from a weight engineering standpoint they are different from conventional surface ships and actually have some features in common with submarines such as the necessity to operate at a constant displacement and the sensitivity to trim. This paper provides insight into the unique aspects of weight engineering on SWATH ships through an example case study. The T-AGOS 23 is the largest SWATH designed and constructed for the U.S. Navy and the experiences of this program will illustrate the unique aspects of a SWATH from the standpoint of weight engineering.
