What Mcm Marine does

MCM Marine, formally M.C.M. Marine, Inc., is a privately held marine construction contractor founded in 1984 and headquartered in Sault Ste. Marie, Michigan. The company provides a full suite of heavy marine services to government, commercial, and industrial clients across the Great Lakes region, including river and harbor improvements, environmental dredging, breakwall construction, dock installation and repair, pile driving, crane services, certified welding, sandblasting, and beach nourishment.

The company's core operating platform is its owned equipment fleet — two 16" cutterhead dredges, a 12" cutterhead dredge, multiple clamshell dredges, tugboats, a 2,000-ton drydock, excavators, and scows — which enables self-performed execution across dredging, structural marine, and support trades without reliance on subcontractors. Its service mix spans environmental, navigational, and commercial marine infrastructure, with named customer segments including the U.S. Coast Guard, tribal governments, government agencies, harbors, power plants, marinas, casinos, commercial fishing operators, Great Lakes freighters, and commercial terminals.

MCM Marine generates revenue through project-based competitive bidding on marine infrastructure contracts. Its customer mix is structurally weighted toward public-sector and harbor authority buyers, with project values and award cycles — rather than recurring subscription or volume pricing — determining annual revenue. The business is capital-intensive, with asset ownership and operational continuity since 1984 serving as the primary indicators of company stability in the absence of disclosed financial statements.
