Professional Development Hours (1 hour) are available for this webinar.Please join the Hampton Roads Section for a presentation by John M. Rosborough, on the sinking of the USS San Diego.
The USS San Diego was the only major USN warship sunk during WWI. After being damaged off the coast of NY it flooded and capsized in about 25 minutes with the loss of only 6 crew. The USN Board of Inquiry investigating the event worked to determine how this loss could have occurred. Was it sabotage, mine or torpedo damage, and were the proper damage control procedures followed? The Captain and crew appear to have done their best before, during, and after the event. As the centennial of the 19 July 1918 sinking approached, the Naval History and Heritage Command embarked on a series of surveys and studies to evaluate the condition of the wreck and to perhaps address the question of how an armored cruiser could be lost in such a manner. The presentation provides an overview of the modeling and simulation efforts to investigate the 100-year old mystery and answer the question of how such a capsize could occur.
SpeakerJohn M. Rosborough
I graduated in 1976 with a BS in Naval Architecture and Marine Engineering from the University of Michigan. I began working with NAVSEC, soon to be combined with NAVSEA, rotating through the Engineer-In-Training program and finishing with field training at the Philadelphia Naval Shipyard. Since then I have worked in functional areas for the Navy all centered around ship stability: Stability and Damage Control, Hydrodynamics, Stability and Weight Control. In 2001 I was selected as Branch Head for the Stability & Weight Control Branch at the Naval Surface Warfare Center, Carderock Division where I worked until 2017. While employed by the Navy, I worked on new designs and in-service ship stability for amphibious ships, combatants, SWATHs, and aircraft carriers. In 1977 the only computer application available for stability calculations was the Ship Hull Characteristics Program (SHCP) – think punched card input… Since then I have had the pleasure of maintaining and improving SHCP, creating pre and post processing software for stability model visualization and results analysis. This includes the software development oversight of the Flooding Casualty Control Software (FCCS), a joint USN & USCG effort, and the Advanced Stability Algorithms (ASA), a time-based progressive flooding software.
Today I provide development of ASA flooding models for USN LFT&E survivability & recoverability programs, develop support software for SHCP, FCCS and ASA model and analysis use, and associated help desk support to the stability community at large via JM Rosborough Stability Consulting, LLC.
