Meeting the needs of our clients and ensuring they receive the highest quality products are our top priorities. In order to provide the highest quality unmanned ship designs and autonomous systems, we partner with innovative, cross-domain Artificial Intelligence (AI) solution providers and reliable, proven shipyards who are our clients can trust.
From initial concept to sustainment and final design, Gibbs & Cox, a wholly owned subsidiary of Leidos, leverages decades of cutting-edge naval architecture with industry leading marine engineering original equipment manufacturers (OEMs) to provide our clients with a product they can rely on.
Our customers benefit from our:
- 90+ years of successful military, commercial, and recreational ship designs.
- Unmanned Maritime Autonomy Architecture (UMAA) ecosystem.
- Plug-and-Play technology which prevents AI vendor lock.
- CYBERSAFE system boundaries and hardened Information Technology and Operational Technology (IT/OT).
How We Apply Marine Autonomy to Complex Situations
When an unmanned ship is expected to perform more than a transit mission between point A and point B, autonomy becomes a much more complex problem. An unmanned military ship is expected to perform the same self-navigation and control functions as an unmanned commercial ship but must also factor in the additional requirements of performing complex mission evolutions in hostile environments. Technical challenges in advancing USV technology include maneuverability, self-maintenance, communication, and cooperative employment of multiple USVs working tougher autonomy. Gibbs & Cox is committed to solving these challenges and advancing the potential of unmanned ship design.
Our Approach to Hull, Mechanical & Electrical (HM&E) Autonomy Integration
To achieve designs capable of long duration missions without human intervention, we collaborate with industry and R&D leaders in HM&E system design. These collaborations provide the necessary reliability and Artificial Intelligence to develop unmanned ships that can monitor, predict, and diagnose performance declines and failures, and then self-adjust its use of available resources to continue meeting ongoing mission requirements.
Below are several features that are key to the integration of HM&E Autonomy Systems. G&C is an experienced provider of each service:
- Smart actuators (e.g. motorized valves)
- Four-part Intelligent Fault Management System
- Active learning
Gibbs & Cox naval architecture expertise draws from nearly 100 years of industry experience and technical development captured in our technical processes and procedures to provide a comprehensive set of design services across a variety of platforms to give our customers quality products.
Our naval architecture services span the ship’s entire lifetime, from early-stage concept designs through detailed design, shipyard construction support, full lifecycle and sustainment support, ship alterations, and service life extensions. Our team of naval architects and marine engineers transform a set of top-level requirements into concept-level definitions to evaluate technical feasibility, cost and performance.
Our engineers combine the use of in-house proprietary naval architecture tools and state-of-the-art software with an extensive technical library to provide accurate naval architecture assessments to our clients. Our use of alternative solutions, developed in trade-off studies to develop data-informed solutions for the design, result in a higher-fidelity design solution.
A few of the key components and outputs of our design process include:
- Overall ship sizing studies and feasibility assessments
- System tradeoff studies
- Preparation of contract guidance drawings and working drawings
- Ship checks
Gibbs & Cox is the largest independent naval architectural firm in the United States and has the resources and processes in place to competitively execute ship designs of all sizes, delivering high-quality products on time and at cost.
Gibbs & Cox’s expertise continues to be sought by shipyards and navies from countries around the world to assist in early-stage studies, contract and design development, and detailed design and production for both new and conversion projects.
Our detail design & construction solutions are highly tailorable to the needs of the program, shipbuilder, and end-customer. Our efforts seek to maximize producibility and affordability while mitigating risk for procurement, planning, construction, test, delivery, and acceptance.

The purpose of this study is to determine if siphonic effects are able to induce a pressure recovery in ship tank overflow piping in favorable flow conditions. The study will go over key features and flow parameters that will likely produce the siphonic effects and the potential that this knowledge imparts for the design of tank overflow arrangements.
Overflow piping is necessary when filling tanks on a large scale since allowing a closed tank to fill past its capacity will likely exceed its design strength resulting in failure. Investigating if a pressure recovery credit can be taken to minimize or negate the effects of frictional losses can have a positive effect to optimize tank and piping design. An optimized design can reduce cost and weight.
The methods implemented in this study include the use of a Pressure Drop Worksheet which uses the Darcy-Weisbach equation for friction loss through a pipe, a computational fluid dynamics simulation program (Star-CCM+), and a fluid flow analysis and design modeling software (Pipe-Flo Professional). Using these three tools, the effects of siphons on pressure drop can be compared across different flowrates. A baseline will be established in order to ensure that each tool will provide a similar result in a simplified scenario. Star-CCM+ and Pipe-Flo Professional will be tested to ensure that a siphon can actually be modeled within the program. A pressure drop vs. flowrate comparison between the three tools will be established. Future work can be performed to determine how upstream and downstream conditions will affect the magnitude of the siphon.
