What Curtin Maritime does
Curtin Maritime is an American-owned, family-run marine solutions company founded in 1997 and headquartered at Pier T in the Port of Long Beach, California. The company operates three integrated service lines — marine transportation (ocean towing, harbor assist, barge charters, and heavy lift project cargo), marine construction (dredging, salvage, and oil and gas support), and shipyard services (vessel design, new construction, conversion, retrofit, and repair) — delivered 24/7 along the U.S. West Coast from San Diego to Alaska. Curtin serves three primary customer segments: port operators (notably Port of Los Angeles and Port of Long Beach), federal and state government agencies including the U.S. Fish and Wildlife Service and U.S. Navy, and private marine companies requiring heavy-lift and ocean towing logistics. The company is led by Captain/Owner Martin Curtin and operates without disclosed institutional or private-equity backing.\n\nCurtin maintains a substantial owned fleet including Invader-class ocean towing tugs (Mabel C and Corinne C, 7,200 combined BHP from twin EMD engines), hybrid-electric harbor tugs (Tigerlily C and Tuuli C, powered by Arc's vertically integrated electric powertrain delivering 4,000+ horsepower with 6 MWh battery buffers), multi-class coastal and combi tugs (Kelly C, Sarah C, Seana C, Gretchen C), and specialty assets such as the DB Avalon clamshell dredge (250' × 77', the largest of its kind in North America with Sumitomo Heavy Industries-designed lithium-ion hybrid system and shore-power connection that reduces CO2 emissions by 30% versus conventional dredges), a 150-ton Lima 2400B mega crane, a Manitowoc 4000W derrick crane, the Eel Pt. ro-ro barge, and multiple ABS Load-Lined deck barges. The in-house shipyard at Pier T handles in-house fabrication, retrofit, and repair work and produced the company's first ground-up vessel build, the Bernardine C, in 2015.\n\nThe company's revenue model is contract-based professional services across its three service lines plus equipment rentals and sales; go-to-market is sales-led with direct B2B engagement, RFP processes for government projects, and long-term service agreements with port operators. The company's most significant commercial move is a $160 million contract signed in September 2025 with Arc Boat Company for eight hybrid-electric ship-assist tugboats for the Port of Los Angeles — the largest commercial deployment of electric workboats in U.S. marine industry history — supported by a January 2026 partnership with Motive Energy to deploy four 1-MW charging systems and a 10-MWh barge-mounted battery energy storage system. Curtin holds multiple sector certifications including ABS, USCG COI, EPA Tier 3/4, and California State Contractors License Board Class A license #969007.
