| ABSTRACT |
|
This study (Part I) examines the theoretical background and proposes systematic dive planning procedures for the surface-supplied diving system (SSDS) to ensure safe underwater search and rescue operations in areas characterized by strong tidal currents and deep waters, such as the 2014 Sewol ferry disaster site. First, the historical development, equipment configurations, and key features of SSDS are introduced. Then, systematic decompression procedures based on the U.S. Navy algorithm are presented. Specifically, single-dive profiles are proposed for two representative underwater scenarios: hull diving at a depth of 26 m and seabed diving at a depth of 48 m. Based on these scenarios, optimal operational plans, including dive frequency and personnel allocation considering tidal conditions, are suggested. However, SSDS requires substantial equipment setup time and extensive manpower, limiting rapid emergency response capabilities. Therefore, a hybrid operation combining SSDS with self-contained underwater breathing apparatus (SCUBA) diving is recommended. The dive plans for SSDS developed in Part I provide foundational data for evaluating its applicability and efficiency through comparative analysis with SCUBA diving under various tidal conditions, as well as for establishing detailed operational and management strategies, which will be addressed in Part II. |
