This report documents a conceptual design effort for the Amphibious Cargo Beaching (ACB) Lighter, a modular barge system which is being developed to replace the Navy Lighter (NL) pontoon causeway system. The ACB Lighter will be rapidly deployed from an auxiliary crane ship and be assembled and operated in sea conditions through sea state three to support Joint Logistics Over the Shore (JLOTS) operations. The focus of this study was on the overall system design requirements, operational goals, objectives and constraining factors. The many constraints upon the size, weight and structural design of modular platforms must be addressed at the outset of design. This report discusses these problems and identifies the primary design criteria. Conceptual designs of a monolithic module as well as an intermodal module concept, the Tri-Module, are presented. These concepts are evaluated against manufacturing cost, maintainability, reliability and interoperability considerations. Continued development of the Tri-Module concept has been recommended.
