Vigor Industrial

What Vigor Industrial does

Vigor Industrial, now operating commercially as Vigor Marine Group, is a Seattle-headquartered private shipbuilding and marine services company founded in 1995. It operates five shipyards — Seattle (a 27-acre facility), Vancouver WA, Portland, San Diego, and Norfolk — delivering naval ship repair and modernization, commercial vessel maintenance, aluminum and steel fabrication, and hybrid-electric vessel conversions. The company holds a NAVSEA Master Ship Repair Agreement and is an authorized depot-level maintenance provider for the U.S. Navy and U.S. Coast Guard, and it is expanding into U.S. Army watercraft manufacturing under the Maneuver Support Vessel (Light) program.

The business model is built on long-cycle federal and state agency contracts. Revenue is generated primarily through cost-plus and fixed-price MRO agreements with the U.S. Navy, U.S. Coast Guard, U.S. Army, and Washington State Ferries, supplemented by commercial ship repair work and limited foreign-navy contracts (Royal Jordanian Navy, Royal Bahrain Naval Force). Strategic activity in 2025 includes partnerships with Samsung Heavy Industries (NGLS surface combatant program) and Saronic Technologies (autonomous vessels), the divestiture of the Complex Fabrication Division, and the announcement of a take-private acquisition by Antin Infrastructure Partners from Lone Star Funds. The underlying technology stack is rooted in heavy marine engineering: drydock operations, aluminum and steel fabrication facilities, and ABB-powered hybrid-electric propulsion integration. There is no disclosed proprietary AI/ML or autonomous-system software developed in-house; autonomy work is pursued through partnerships rather than internal R&D.

Core offering

Vigor Industrial (now operating as Vigor Marine Group) provides ship repair, maintenance, modernization, and marine fabrication services for the U.S. Navy, U.S. Coast Guard, U.S. Army, state ferry authorities, and commercial maritime clients. The company operates five shipyard facilities across the U.S. (Seattle, Vancouver, Portland, San Diego, and Norfolk) and was the first U.S. shipyard to complete a hybrid-electric passenger ferry conversion. Its three service lines are Maintenance & Modernization, Marine Fabrication, and Marine Services.

Product overview

Vigor Marine Group is a unified maritime company formed from the merger of Vigor Industrial and MHI Holdings (now under Carlyle and Stellex Capital Management ownership). The company operates as a single unified organization offering three interconnected service lines: Maintenance & Modernization (ship repair, drydocking, and modernization for Navy, Coast Guard, and commercial vessels), Marine Fabrication (aluminum and complex fabrication for landing craft, combatant craft, pilot boats, and passenger vessels), and Marine Services (support services including environmental and industrial services). The company operates facilities in Seattle (27-acre Navy maintenance hub), Vancouver, Portland, San Diego, and Norfolk, serving U.S. Navy, U.S. Army, U.S. Coast Guard, Washington State Ferries, and commercial maritime clients. Notable products include the Maneuver Support Vessel (Light) for the U.S. Army, Combatant Craft Heavy for the Navy, hybrid-electric ferry conversions, and various commercial vessels.
