Marine Design Dynamics

What Marine Design Dynamics does

Marine Design Dynamics, Inc. (MDD) is a Washington, D.C.-based naval architecture and marine engineering consultancy founded in 2011 (incorporation as MDD, Inc.; firmographics report a 2005 origin likely tied to predecessor activity). The firm operates across three integrated service lines: naval architecture and marine engineering (requirements definition, detailed ship design, modification, and repair oversight), research and development (advanced composites, water purification, energy modeling, diesel diagnostics), and hardware fabrication of specialized shipboard and expeditionary products including the patented Mobile Offshore Ship (MOS) reconfigurable platform, Heavy UNREP/E-STREAM replenishment systems, Remote Water Purification System, Energy and Water Conservation System, High Volatility Fuel Module, and AN/PAQ-6 wireless UNREP communications link. Its shipboard energy management process — adopted by the US Navy and Military Sealift Command — has identified over $100M in energy savings across the MSC fleet and underpinned a $355M MSC fuel budget reduction commitment.

MDD's commercial model is professional services revenue through US federal contract vehicles, primarily as a prime contractor on Seaport-e (all seven geographic zones), NAVSEA 05 Ship Design Services, and direct MSC prime contracts, with parallel subcontractor positions to BMT Designers and Planners, Computer Sciences Corporation, and Gryphon Technologies on multi-year IDIQ awards. Customer concentration is dominated by the US Navy, Military Sealift Command, NOAA, US Coast Guard, US Marine Corps, and Office of Naval Research, with a smaller commercial book that includes Carnival Cruise Lines (fleet-wide energy program), the Staten Island Ferry (Molinari Class fuel monitoring achieving 23–30% propulsion fuel reductions), and Maersk Lines Limited. The company is founder/privately owned with no disclosed institutional backing, reports 1–10 employees, and markets primarily through contract vehicle qualifications and a technical project portfolio rather than traditional demand-generation channels.

Core offering

Marine Design Dynamics provides naval architecture and marine engineering, research and development, program management, and hardware fabrication services for U.S. Navy, Military Sealift Command, USMC, NOAA, U.S. Coast Guard, and commercial maritime customers. Its flagship capability is a proprietary shipboard energy management program that has identified over $100M in energy savings across the MSC fleet, complemented by ship modification and repair oversight and the design of expeditionary hardware such as the Remote Water Purification System and FOB Energy and Water Conservation System.

Product overview

Marine Design Dynamics (MDD) is a marine engineering and naval architecture consultancy that provides professional services to government and commercial clients rather than a single product offering. The company operates across multiple service lines including Naval Architecture and Marine Engineering, Advanced Concept Development, Program Management, Research and Development, Shipboard Energy Reduction/Management/Assessment, Information Technology/Emissions Testing, and Ship Modification and Repair. MDD's portfolio includes technology demonstrators and specialized products developed through SBIR programs and internal R&D, such as the FOB Energy and Water Conservation System (EWCS), High Volatility Fuel (HVF) Module, Reverse Osmosis-Water Packaging (RO/WP) Module, Remote Water Purification System (RWPS), Heavy UNREP/E-STREAM systems, Mobile Offshore Ship (MOS) concepts, and various energy conservation solutions for military and commercial vessels. The company also conducts hydrodynamic testing, supports combat craft development, and provides ship modification services with managed shipyard relationships.
