OPERATIONALIZING DIGITAL THREAD THROUGH MODEL-BASED SYSTEMS ENGINEERING METHODS FOR HEAVY LIFT AND SALVAGE OPERATIONS

Abstract

Challenges exist in determining out how to effectively integrate legacy analysis tools with Model-Based Systems Engineering (MBSE) tools to accomplish a digital transformation. In this study, we analyze the legacy Program of Ship Salvage Engineering (POSSE), an analysis-based tool that helps salvage engineers determine how critical a damaged ship situation is. Salvage engineers utilize POSSE to provide real-time assessments of complex salvage situations and to communicate with other commercial salvage software packages. The research focus of this study was to ask, "How can NAVSEA 00C accomplish a digital engineering transformation utilizing the legacy POSSE program for their heavy lift and salvage operations using MBSE methods?" This research used system modeling tools to model salvage operations by creating a digital thread from the systems model to the POSSE analysis tool. The main part of the approach demonstrated a working product integrating POSSE and Cameo Enterprise Architecture (Cameo). The study investigated the possibilities of operationalizing the digital twin concept in conjunction with the digital thread. The results of this study can help assess the advantages the Navy can realize by operationalizing digital threads and digital twins through MBSE.
