American Marine Corporation

What American Marine Corporation does

American Marine Corporation is a privately held, founder-owned specialty marine contracting and commercial diving company incorporated in 1975 in Hawaii (originally as American Divers, Inc.) and operating under the American Marine Services Group (AMSG) umbrella. The company delivers four integrated service lines — marine construction (coastal/offshore construction, welding, dredging, waterfront infrastructure), commercial diving (including mixed-gas deep-water and Arctic-class operations), marine transportation (tugboat tows, crew boat charters, oil tanker tending, logistics support), and salvage and environmental response — supported by an owned fleet of eight ocean-going tugboats, six crew boats, multiple crane and deck barges, and dive vessels.

The company is organized around three regional bases in Anchorage, Alaska; Terminal Island (Los Angeles), California; and Honolulu, Hawaii, serving federal, state, and municipal government agencies alongside private-sector oil & gas and marine transportation customers. Projects are delivered on a project-based, custom-quoted basis under direct enterprise engagement, with no third-party channel partners. AMSG sister entities — Pacific Environmental Corporation (PENCO) for environmental response and American Workboats Inc. for fleet asset ownership — extend the platform's emergency response and capital asset capabilities.

The company monetizes primarily through professional-services project contracts (marine construction, diving, transportation, salvage, environmental remediation) and equipment charter revenue. Customers include the U.S. Navy, port authorities (Port of Alaska, Port of Los Angeles, Maunalua Bay), oil & gas operators on Cook Inlet and the North Slope, and federal/state environmental cleanup programs. The company holds no disclosed external funding, maintains 50 years of continuous operation, and was recognized with the AGC & GCA Zero Incident Safety Award in 2026.
