Signet Maritime

What Signet Maritime does

Signet Maritime Corporation, founded in 1976 and headquartered in Houston, Texas, is a privately held U.S. maritime services and shipbuilding company. The business operates two integrated functions: marine transportation services (ship assist, ship escort, harbor and offshore towing, offshore support, subsea operations, rig moves, maritime aerospace, emergency response, and dynamic mooring) delivered through a diversified fleet that includes Robert Allan Limited-designed Rotortugs and EPA Tier 3 ASD tugs, and a full-service shipyard (Signet Shipbuilding & Repair) located on the Pascagoula River in Mississippi. The shipyard is capable of dry-docking nine vessels simultaneously, supported by a 600-ton Marine Travelift, the Signet 1650 floating drydock with 1,650-ton lifting capacity, 43,000 sq ft of covered fabrication space, and 54,000 sq ft of level concrete for multi-vessel construction. Signet holds an extensive stack of maritime certifications (ISO 9001:2015, ISM, STCW-2010, SIGTTO, MTSA, SEEMP, 46 CFR Subchapter M, ABS SQ with 'ISM Plus!' designation, MLC 2006, SOLAS, MARPOL, ISPS) and serves customers across shipping companies, offshore energy operators, government/military (including the U.S. Navy), and maritime shipowners along the U.S. Gulf Coast and East Coast, with project work reaching West Africa.

The company is 100% owned by founder J. Barry Snyder, who serves as President and CEO. Revenue is generated through transaction-fee-based contracts (per-job or term) for marine services, shipbuilding and repair engagements, and published port tariff rates at six U.S. operational complexes (Houston, Ingleside, Brownsville, Pascagoula, Jacksonville, and Port Canaveral). In August 2025, Signet completed a $132 million debt refinancing arranged solely by First Citizens Bank to retire its prior first lien facility and fund development capital expenditures, following a broader $250 million capital expansion program that included the acquisition and integration of the Harvey Gulf OTV fleet. The business is sales-led, with services contracted directly through corporate offices and operational complexes rather than through intermediaries.
