T-Craft Seabase Ramp Loads Model Test Data Report

Abstract

A seakeeping model test was performed in the Naval Surface Warfare Center. Carderock Division (NSWCCD) Maneuvering and Seakeeping (MASK) Basin on an offshore seabase comprised of a government designed transformable craft (T-Craft) model and a large medium speed roll-on roll-off (LMSR) cargo ship model. The seabase was formed by connecting these two models with a fixed two degree of freedom cargo transfer ramp. The primary objective of the test was to measure the motions of the models and the loads on the ramp connections under various loading, operational and wave conditions. The test matrix included full-scale speeds of zero and four knots in head and bow quartering seas (representing scaled Sea States 3 and 4) and for three different loading conditions on the TCraft and ramp. The matrix also included three different configurations of the offshore seabase. These configurations included a Tandem scenario, a Side-by-Side scenario, and a Hinged scenario. The data collected from the test were to be used to identify the conditions that produce the most severe loads on the ramp connections and relative motions of the seabase.
