Seakeeping and Maneuvering Assessment of SWATH AGOR 23 Configurations.

Abstract

DTNSRDC was tasked to investigate the seaworthiness of designs for the AGOR-23, an oceanographic research vessel. The goal was to see of designs which were within cost constraints could also meet the operational requirements for seakeeping and station keeping A series of three similar designs, with different displacements, was considered. The effect of hull form modifications on seaworthiness was investigated. The seaworthiness of an additional small displacement design was also evaluated. For this design, thrusters which met station keeping requirements were chosen. Four SWATH designs considered in this investigation meet the seakeeping operational requirements. Two with similar displacements differ in design. One has a large (15.29 meters) longitudinal metacentric height (GML) and inactive stabilizing fins and the other has a smaller (7.67 meters) GML with active control for the stabilizers. Waterplane area, strut length, and lower hull length also differ.
