Tidewater Marine International

What Tidewater Marine International does

Tidewater Marine International, Inc. (TMI) is a veteran-owned ship repair support services company founded in 2017 and headquartered at 1008 Jefferson Ave, Newport News, Virginia. The firm specializes in full-service tank cleaning and gas freeing for commercial and government vessels of all sizes, operating in compliance with USCG, USN, EPA, DEQ, OSHA, and local marine chemist standards. Core offerings include cleaning and removal of diesel/fuel oil, lube oil, CHT/sewage, gasoline, potable water, voids, cofferdams, ballasts, and grey/black water tanks, complemented by hazardous and non-hazardous waste handling, oil reclamation, hot and cold pressure washing, and steam cleaning.\n\nBeyond tank cleaning, TMI delivers a broad portfolio of industrial marine services: welding, sandblasting and dry ice blasting, interior and exterior painting (including underwater hull preservation), interior and exterior scaffolding, precision machining, insulation and piping, general labor support, deionization, lead abatement, and competent person services. The company also offers Licensed CPR and First Aid Training certified by the American Red Cross. All services are available 24/7 with immediate response to emergent jobs, supported by a management team with 15-20 years of collective industry experience and monthly continuing education programs.\n\nTMI's revenue model is project-based professional services with quote-driven pricing specific to each engagement. The go-to-market motion is direct enterprise field sales to commercial and government vessel operators in the Southeast Virginia region, with no intermediaries or resellers. Marketing is minimal, relying on BBB accreditation, SAM registration as a Veteran Owned Business (Federal ID 36-4879244, DUNS 080935622, NAICS 562998), and service quality reputation rather than digital channels. The company is founder-led by Jason Martin (President) and Suzanne Martin (Vice President), privately held, and bootstrapped with no external funding disclosed.

• Detyens Shipyard: Charleston, SC commercial shipyard providing repair, conversion, and topside services. Comparable as a mid-Atlantic/Southeast ship repair competitor chasing similar commercial and government work as TMI.

Regional players

• Bay Ship & Yacht Co. Northern California shipyard providing full-service ship repair and conversions. Comparable in service mix to TMI but operates on the U.S. West Coast, so a regional rather than direct competitor.

• General Dynamics NASSCO: Large San Diego-based shipbuilder and repairer serving the U.S. Navy and commercial customers. Adjacent comparable to TMI in ship repair and marine services, but at substantially greater scale and on the West Coast.
• BAE Systems Norfolk Ship Repair: Major Navy-focused ship repair prime contractor operating the Norfolk shipyard. Comparable to TMI as a US Navy/USCG MRO provider in Hampton Roads, but with vastly greater scale, bonding, and contract scope.
