FUNCTIONAL SYSTEM DEVELOPMENT

Gibbs & Cox, Inc. has a history of evolving ship system designs from early-stage feasibility studies to fully engineered and designed systems documented by detailed fabrication drawings. The key to our success in functional system development is the application of a phased-development process, where the level of detail associated with the system design is gradually increased for each successive design product. This process has been successfully executed on every Gibbs & Cox, Inc. total ship detail design program, and features the development of a variety of design and engineering products, including:

System diagrams from concept to production-level Engineering calculation packages Inquiry specifications for system components (to request data from vendors)

Build Specifications for system fabrication and installation Purchase Specifications for procurement of components Fabrication drawings for each system, including detailed component arrangements and complete bills of material

Application of Functional System Development to Naval Shipbuilding Programs

Gibbs & Cox, Inc. has applied this functional system development process to a number of Naval shipbuilding programs, including:

Littoral Combat Ship DDG 51 Flight IIA Australian Air Warfare Destroyer

T-AKE Contract Design DD 21/DD(X) Blue Team USCG Deepwater Cutters

Systems developed for these programs using our functional system development process include:

Main and auxiliary propulsion (including integrated electric propulsion) Prime movers Gears Shafts, bearings and seals Propulsion auxiliary systems such as lube oil ,fuel, cooling water, cooling air and combustion air Propulsion and machinery control systems Electrical generation and distribution Main power (medium and low voltage AC) Lighting Special frequency power

Command and Control Systems Navigation Interior communications Telephones Computer networks Announcing Alarm and indicating Combat Systems Auxiliary Systems Heating, ventilation and air conditioning (HVAC) Piping systems Seawater Fresh water Plumbing and drains Compressed gases Fuel and Lube oil transfer Aviation fuel systems Mission vehicle fuel systems Replenishment at Sea systems Mission support systems Recovery, handling and stowage systems

Gibbs & Cox, Inc. utilizes an extensive suite of software as part of our functional system development process. Our software suite ranges from word processors, spreadsheets, and graphics tools to more elaborate computer-aided design and engineering tools, including:

• Propulsion system design and engineering software
• Electrical system design and engineering software
• Electronics system design and engineering software
• Auxiliary system design and engineering software
• 3-D modeling and CAD software
