How Gibbs & Cox Successfully Meets U.S. Navy Ship Design Requirements

To execute our commitment to achieving the highest quality naval ship designs and meeting our client’s needs, Gibbs & Cox follows strict naval architecture rules, regulations, and design requirements.

Gibbs & Cox Adheres to Rigorous Ship Design Rules & Standards

Naval ship designs are tailored to meet an immense set of specifications. These specifications include the Navy’s unique governing rule set and numerous governmental and industrial regulations and standards. U.S. naval ship designs are developed using the Naval Combatant Design Specification or other Ship Class System Specification as the governing rule set. These rule sets are then integrated with the additional design criteria expressed in the contract to develop the ship design. Other criteria examples include NAVSEA Contract Drawings and Contract Guidance Drawings, U.S. Navy Design Data Sheets, U.S. Navy Design Practices and Criteria documents, U.S. Government Specifications, U.S. Government and Industry Standards, and Installation Control Drawings and Interface Control Drawings.

We Ensure Compliance Through Every Step of the Design Process

Gibbs & Cox ship design capabilities range from Preliminary Design through Detailed Design and Post-Delivery Engineering Change modification packages. We rigorously decompose all design requirements by work element at the beginning of Preliminary Design to capture and de-conflict each requirement. This approach allows the resultant design to be as integrated and de-risked as possible, from a requirements standpoint, before starting Functional Design. The requirements decomposition continues into Functional and Detailed Design to ensure that the final design is compliant with all requirements and all requirements can be tested and verified.

Our Ship Design Products Include:

  • Preliminary Design Products – Drawings and reports defining the design at a preliminary level of detail to prove feasibility of the design and identify potential design risks needed for adjudication in the next design phase
  • Contact Design Products – Drawings, analyses, and calculations further defining the ship’s structure and HM&E systems to allow the development of equipment Purchase Technical Specification and material parts list at the start of Functional Design
  • Detailed Design Products – Functional reports and calculations necessary to achieve Navy acceptance of the design. Production Drawings of all structural members and details, including hull, foundations, and joint designs, piping spool piece drawings, and electrical one-line drawings, cableway routing and alarms, sensors and control drawings.
  • Post Delivery Products – Work items to support engineering changes, Inclining and Ship trial support


Meeting Our Client’s Needs is the Top Requirement in Every Phase of Naval Ship Design

Our team of experienced ship designers and engineers ensures that all of our designs are fully integrated and compliant with all contractual requirements to meet our client’s expectations and deliver top-quality solutions.

Gibbs & Cox plans on cultivating these attributes with our expansion into emerging maritime markets. Over the last several months, we have hired a number of staff from the Houston area and expect this trend to continue as we continue to grow with our recent contract wins.

Todd Carrico joins us as Director of the Houston office from SBM Offshore, where he served as the Technology and Business Development Manager, focusing on early project development for the SBM Offshore Houston Regional Center. Prior to SBM Offshore, Todd was the Seakeeping Division Model Experimentation Branch Head at NSWC Carderock, where he was responsible for complex model test programs, including DDG 1000 and the Orion Recovery test programs. He earned a Bachelor of Science in Ocean Engineering from the University of Rhode Island. Additionally, he holds a Master of Science in Naval Architecture and Marine Engineering from the University of New Orleans. Todd is active in the Texas Chapter of SNAME as well as many of the international engineering conferences based in the greater Houston area.

In anticipation of a continued presence in Houston, Gibbs & Cox intends on opening a physical location once the COVID-19 pandemic recovery is underway.
