a. The type of work that comprises ship repair, and the conditions under which it is performed, require that NAVSEA contract only with ship repair companies that are fully capable of conducting all aspects of shipboard work. By its nature, shipboard repair work is complex and demanding. The compact arrangement of machinery and systems aboard ship, the sophistication of systems installed in naval ships, and the Navy's absolute requirement for reliable operation, create a unique repair environment that demands special expertise and capability.
Further, naval ships are designed and built with a high degree of interaction among components and systems. Repairs or modifications to a single system or component may have wide spread effects on the operation of many other systems or components that are physically remote from the one being repaired. A thorough understanding of these effects and the ability to manage shipboard work as an integrated package are absolutely essential..
