LASH Amphibious Post-Assault Support (LAPS) Mission. Phase I. Conceptual Design Analysis.
Abstract
The Conceptual Design Analysis of the LASH Amphibious Post Assault Support (LAPS) Mission is a study to determine the feasibility of utilizing the LASH vessel as a self-sustaining support vessel to transport the large components and equipment needed to implement over-the-Shore Discharge of containership (OSDOC) resupply of an amphibious operation. This study goes into considerable detail evaluating different lifting technique such as lifting beams employed with a 2-point lift lifting beam with counterweights and compression members, cantilever lift frames, and external lift methods, all requiring different kinds of lifting hardware. Each item of outsize cargo is considered in exploring each lifting technique and calculations are included showing the practicality of each component lift compared to crane and hardware capability as well as trim and stability considerations of the component when discharged in an open sea. Conclusions as to the most viable lifting technique to be developed further are based on the following considerations: extent of modification, lift capability, intraship mobility, ship down time, cost and yard facility requirements. On this basis, the cantilever lift frame is the technique recommended for further development comprising Phase II of the LAPS Program. (Author)
