The focus of our company is design and analysis. On the design side, DEC can provide feasibility studies, conceptual design, functional level drawings, and detailed production level drawings in AutoCAD and ShipConstructor for both conversions and new construction. We are experienced in providing all regulatory submittals and responses to both the class society and the US Coast Guard, for structure, stability, mechanical and electrical systems.

On the analysis side, DEC can provide finite element analysis of hull structures and components ranging in complexity from equipment packages and equipment foundations to full ship models. We have experience with composites, aluminum and steel vessels, providing stress, thermal and fatigue analyses for numerous structures in various operational conditions. Our capabilities include the analysis of a vessel’s hydrodynamic motions and loads, ship systems pipe stress and flexibility, and hull form analysis and optimization through computational fluid dynamics. Also, DEC is authorized to perform special analyses for the U.S. Navy.

DEC also has the equipment and personnel to provide Habitability Certification Testing for vessels and offshore installations through its affiliate, Hab-CerT, LLC.

We use a variety of design and management tools to include the following:

          Ansys Aqwa – hydrodynamic motions & loads
          AutoCAD – 2-D and 3-D design
          CD-Adapco STAR CCM+ - Computational fluid dynamics
          GHS – General Hydrostatic Software
          Intergraph CAESAR II – pipe flexibility
          MAESTRO – finite element and fatigue
          MS Project - scheduling
          Multisurf – hull fairing
          NavCAD – resistance and powering
          NEi/NASTRAN – finite element analysis
          Pipe Flow – piping system design software
          RHINO – 3-D modeling
          ShipConstructor – 3-D production modeling
