The United States Navy (USN) is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States.  The U.S. Navy is the largest, most capable navy in the world, with the highest combined battle fleet tonnage.  The U.S. Navy service has 336,978 personnel on active duty and 101,583 in the Navy Ready Reserve.  It has 290 deployable combat vessels and more than 3,700 aircraft in active service as of June 2019*


Managing The Complexity in Design Change




Their Challenge 

In recent work at US Navy Naval Surface Warfare Centre NSWC-SSES Advanced Machinery Systems Integration Branch (Philadelphia), an experienced Naval engineer was working on a minor order: to move a chilled water cooler from beneath deck to above deck in a mess barge.  
Whilst this might sound like a fairly straight forward task, he was struggling at having to understand the numerous documents on the individual systems involved; how pipes and machines and spaces are all inter-dependent in the tightly crowded barge; and where every system has been sized, engineered, and positioned for the current configuration.  
The "data forensics" undertaken which was required was affecting a seemingly innocuous task and was, in fact, proving extremely daunting, and allowed much less time for the actual “valuable” engineering work required to make the design change.  


The BOXARR Solution

Deployment of BOXARR allowed the engineer to simply and quickly construct a comprehensive “boxes and arrows” model of the various systems involved, and how they depend upon one another.  Armed with this model, the engineer was able to have a clear visualisation of the task at hand in a single place, allowing him to get on with the real engineering involved, and completing his task faster and more effectively, saving significant man hours.
