The collisions and accidents occurring throughout the U.S. Navy surface fleet warranted the appointment of a 34-personnel review team to analyze the three ship collisions and one grounding in 2017. These accidents resulted in 17 U.S. Navy sailors' deaths and damage to the operational ships. There were 12 incidents between 2007 and 2017; this increase in frequency drove the need to conduct the review. The concern is that the fundamental causal factors were not adequately addressed and that a future collision is imminent without further corrective action. This thesis uses Dr. Nancy Leveson's Systems-Theoretic Accident Model and Process (STAMP) model of accident causation to analyze two U.S. Navy ship collisions in 2017. The Causal Analysis based on STAMP (CAST) is conducted on both collisions, and an analysis of the results is compared with the traditional U.S. Navy findings. CAST examines the system's safety control structure to assess why the designed controls were inadequate to prevent the accident. The goal of this thesis is to determine whether a STAMP approach to accident analysis would add value to the U.S. Navy. If so, it seeks to determine what new factors the CAST analysis provides and how it may be used to prevent future mishaps.

The Systems-Theoretic Accident Model (STAMP) developed by MIT's Dr. Nancy Leveson was applied in this thesis to a ship navigation control system used on U.S. Coast Guard buoy tenders. The legacy system installed on the Service's 16 sea-going buoy tenders experienced numerous incidents that had potential to be hazardous to the ships and their crews. Faced with the dual needs of ensuring safety of mission execution and restoring confidence in the overall ship control system, yet faced with a limited budget, Coast Guard decision-makers elected to conduct a partial recapitalization of the system's hardware and software. This thesis explores the application of system safety methods to analyze the legacy system on the seagoing buoy tenders. An accident analysis of a particular incident was conducted using STAMP methodologies, and its results were compared/contrasted with the results of a more traditional root cause failure analysis that was contracted by the Coast Guard following the incident. Several added insights pertaining to system safety and process improvement were obtained by using STAMP. Additionally, a hazard analysis was performed on the control system using STAMP techniques. This hazard analysis yielded 92 specific design requirements that may be incorporated into future system upgrades on these or similar vessels. The thesis concludes that STAMP methodologies are appropriate to generate actionable recommendations for future control system upgrades on U.S. Coast Guard buoy tenders. It also concludes that STAMP techniques may lead to safer controls in the greater hierarchical control structure for shipboard buoy tending operations. Finally, suggestions are made for future research/application of STAMP principles in the Coast Guard's management of operational safety, asset acquisition, and cybersecurity.

A new approach to safety, based on systems thinking, that is more effective, less costly, and easier to use than current techniques. Engineering has experienced a technological revolution, but the basic engineering techniques applied in safety and reliability engineering, created in a simpler, analog world, have changed very little over the years. In this groundbreaking book, Nancy Leveson proposes a new approach to safety—more suited to today's complex, sociotechnical, software-intensive world—based on modern systems thinking and systems theory. Revisiting and updating ideas pioneered by 1950s aerospace engineers in their System Safety concept, and testing her new model extensively on real-world examples, Leveson has created a new approach to safety that is more effective, less expensive, and easier to use than current techniques. Arguing that traditional models of causality are inadequate, Leveson presents a new, extended model of causation (Systems-Theoretic Accident Model and Processes, or STAMP), then shows how the new model can be used to create techniques for system safety engineering, including accident analysis, hazard analysis, system design, safety in operations, and management of safety-critical systems. She applies the new techniques to real-world events including the friendly-fire loss of a U.S. Blackhawk helicopter in the first Gulf War; the Vioxx recall; the U.S. Navy SUBSAFE program; and the bacterial contamination of a public water supply in a Canadian town. Leveson's approach is relevant even beyond safety engineering, offering techniques for “reengineering” any large sociotechnical system to improve safety and manage risk.

Pearl Harbor will long stand out in mens minds as an example of the results of basic unpreparedness of a peace loving nation, of highly efficient treacherous surprise attack and of the resulting unification of America into a single tidal wave of purpose to victory. Therefore, all will be interested in this unique narrative by Admiral Wallin. The Navy has long needed a succinct account of the salvage operations at Pearl Harbor that miraculously resurrected what appeared to be a forever shattered fleet. Admiral Wallin agreed to undertake the job. He was exactly the right man for it _ in talent, in perception, and in experience. He had served intimately with Admiral Nimitz and with Admiral Halsey in the South Pacific, has commanded three different Navy Yards, and was a highly successful Chief of the Bureau of Ships. On 7 December 1941 the then Captain Wallin was serving at Pearl Harbor. He witnessed the events of that shattering and unifying "Day of Infamy." His mind began to race at high speeds at once on the problems and means of getting the broken fleet back into service for its giant task. Unless the United States regained control of the sea, even greater disaster loomed. Without victory at sea, tyranny soon would surely rule all Asia and Europe. In a matter of time it would surely rule the Americas. Captain Wallin salvaged most of the broken Pearl Harbor fleet that went on to figure prominently in the United States Navys victory. So the account he masterfully tells covers what he masterfully accomplished. The United States owes him an unpayable debt for this high service among many others in his long career.
