Marine Hydraulics International

What Marine Hydraulics International does

Marine Hydraulics International (operating as MHI Ship Repair & Services) is a privately held, full-service ship repair and conversion contractor headquartered at 543 East Indian River Road in Norfolk, Virginia. The company operates a shipyard, piers, and waterfront facilities on the Elizabeth River at the Port of Hampton Roads, including a 1,220 ft x 70 ft wide pier with 36 ft of water depth capable of berthing four ships simultaneously, supplemented by a secondary Midtown Pier facility at 1215 Warrington Ave. MHI provides structural repair, steel plate fabrication, paint and coatings (through a state-of-the-art environmentally controlled paint, blast and drying booth), pipe and valve repair, electrical services, machine work, and engineering services for hull and machinery systems.

The company's customer base is anchored by U.S. federal and defense customers — the U.S. Navy, Military Sealift Command, and the Maritime Administration — alongside commercial ship owners and, through Titan affiliate relationships, defense prime contractors. Workforce totals approximately 500 employees specialized in marine ship repair, with security clearance and DBIDS badge processes in place to support government contracting work. MHI holds NACE (Level 1, Level 3, SCAT) and SSPC (QP1, QCS) coatings certifications and has been recognized by the Shipbuilders Council of America and Signal Administration for safety and quality.

MHI is a wholly-owned subsidiary of Titan Acquisition Holdings, a bicoastal ship repair and fabrication platform formed in 2019 through the combination of MHI Holdings and Vigor Industrial by The Carlyle Group (via its $2.4B U.S. Equity Opportunity Fund II) and Stellex Capital Management. The Titan family also includes Vigor Industries, Continental Maritime of San Diego, Seaward Marine Services, and Accurate Marine Environmental. Revenue is generated through negotiated, project-based contracts for repair and conversion work, with no publicly disclosed pricing. As part of Titan, MHI benefits from a coast-to-coast footprint following the 2020 announced acquisition of Huntington Ingalls Industries' San Diego Shipyard (with HII holding a minority interest in Titan).
