SES T-Craft Model Testing

Abstract

The aim of this project was to perform seakeeping and resistance tests using the NSWCCD Surface Effect Ship (SES) T-Craft model, DTMB number 5687, in Carderock's 140 foot tow basin. Seakeeping tests were previously performed on this model by the Seakeeping Division (Code 55) in the Maneuvering and Seakeeping Basin (MASK), but underway resistance tests were not performed. This project conducted resistance tests in calm water and various regular wave conditions, zero speed motion tests at headings of 180 and 90 degrees, as well as pitch, heave, and roll decay tests. It was of interest to understand the effect of the SES air cushion on ship motions and resistance, therefore RAO graphs were developed to describe ship motions, along with the resistance graphs at full, half, and zero cushion. Zero speed motions tests were conducted in the 140 ft basin for the same wave conditions used in the earlier MASK tests for comparison.
