SHIP ALTERATION DESIGN & ENGINEERING
Gibbs & Cox offers a full range of capabilities at all stages of design, engineering, construction, and life cycle support for a broad variety of marine vessels. Services include naval architecture, marine engineering, marine electrical design, plumbing and pipe routing, systems design, and structural design, all taking advantage of several advanced engineering analysis techniques and sophisticated production design tools.
Gibbs & Cox supports Owners and Shipyards in developing complete Contract Design packages plan packagefor class and regulatory submittal and shipyard bidding. We have recent experience working with all major Class Societies including ABS, Lloyds, and DNV in steel, aluminum, and high speed rule sets. We also work direct with the U.S. Coast Guard Marine Safety Center (MSC), and local Officer and Charge of Marine Inspections (OCMI) on certificated U.S. vessels.

Detail and Production Design
Production Design develops the integrated 3-D CAD Product Model for the vessel based on classed and approved functional drawings, vendor drawings, and the shipyard’s build strategy into a configuration optimized for vessel construction. Production drawings and information are extracted from the 3-D Product Model to support complete construction of the vessel in a sequence and format best aligning with the build processes and work centers at the shipyard. This includes 3D and 2D drawings and CNC data for structural assembly, piping, mechanical, hull outfitting, electrical, and HVAC.
Gibbs & Cox has uses various 3D CAD/CAM software tools including ShipConstructor and Intergraph. We apply over 30 years of CAD experience and 35 processes for modeling, drawing extraction, Design Control, and configuration management under an ISO 9001 Quality Management System
Our processes are scalable and customizable to shipyard’s capabilities, preferences, vessel complexity, and schedule. During Production Design we follow a Design for Production (DFP) and Design for Maintenance (DFM) approach and proven methods to improve construction efficiency for the shipyard and reduce lifecycle operating costs.
As needed for specialty projects, we use the leading industry software for structural Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD), electrical power systems analysis, modeling tools.
We remain on the forefront of integrating latest technologies into designs for efficiency, environment, and performance. We have recent design work integrating Ballast Water Treatment Systems (BWTS) for IMO and USCG Compliance and Urea-based Selective Cathodic Treatment Systems (SCR) forEPA Tier 4 and IMO Tier 3 Compliance. We have performed in-house design work on LNG single and dual fuel vessels. We help clients with trade-off and payback analyses when considering alternative fuels. We perform hull form powering and seakeeping performanceassessment improvement trade-offs with our suite of tools including Computational Fluid Dynamics (CFD). For improved crew and passenger comfort, we apply methods to reduce noise and vibration in new designs. For research, yacht, and military vessel designs requiring acoustically silence above and below the waterline, we apply a more stringent design approach.
During construction, we support shipyards on owner’s with on-site and off-site support in engineering and project management support. Our capabilities include project management, port engineering, field engineering support, weight control, calculations for lifts & turns, launching, and docking, and stability test/experiments, and test & trials support.
