What Stabbert Maritime does
Stabbert Maritime Holdings, LLC is a privately held, family-owned maritime services group founded in 2012 and headquartered in Seattle, Washington. The company operates through three core divisions: Ocean Services (OS), which provides science and research vessels to government and academic clients including NOAA, the US Navy, and Johns Hopkins University; Ocean Sub Sea Services (OS/3), which delivers DP2 and DP1 multi-purpose support vessels, dive support vessels, and specialty vessels for offshore oil & gas, subsea construction, and renewable energy projects across the Gulf of Mexico, Mexico, Brazil, California, and the Arctic; and Stabbert Marine and Industrial (SMI), a full-service shipyard operator with two Pacific Northwest facilities in Ballard (Seattle) and Anacortes, Washington, capable of dry-docking vessels up to 600 feet with 70,000 sq ft of covered fabrication space, marine railways, and heavy-lift cranes up to 300 tons.
The company operates a fleet of seven purpose-built vessels — Ocean Guardian, Ocean Valor, Ocean Titan, Ocean Lee, MB480, Ocean Intrepid, and Kimberly C — each configured for specific mission profiles ranging from DP2 offshore construction and heavy lift to acoustically quiet research operations and deep-ocean towing. SMI's shipyards deliver structural steel, propulsion upgrades, electrical modernization, mechanical and piping services, and full drydock overhauls for commercial, government, and offshore customers. The proprietary Vessel Lifecycle Renewal Program converts aging or underutilized vessels into mission-ready assets with 20-30 additional years of service life, supported by NAVSEA, ABS, and DNV certifications and a US Navy-approved Quality Management System.
Stabbert generates revenue through project-based shipyard services (with quote-based budgets ranging from under $25K to over $1M per engagement) and vessel charter operations structured around multi-year contracts and recurring charters. The company sells exclusively through direct enterprise sales channels targeting energy operators, government agencies, research institutions, and offshore construction firms. Geographic reach spans North and South America with active operating presence in Mexico (regional office in Ciudad del Carmen), Brazil, the Arctic, and Antarctic regions. Leadership is concentrated in the founding Stabbert family, with Dan Stabbert as President and CEO and a senior team combining more than 100 years of operational maritime experience.
