Dees Marine Consulting, Inc. brings over three and a half decades of hands-on leadership in heavy marine civil construction to every project. Founded on firsthand experience managing the Pacific Coast's most demanding marine infrastructure work, we deliver expert consulting that cuts through complexity.
From the earliest planning phases through final execution, Dees Marine Consulting provides the oversight, problem-solving, and technical authority that comes only from actually doing the work for decades. We've managed dredging operations, overseen bridge construction over navigable waters, coordinated submarine cable laying, and led complex marine civil projects from Mexico to Canada.

Dees Marine Consulting operates across the entire U.S. West Coast and into international waters. Our project history spans three countries and the full length of the Pacific coastline — harbors, rivers, estuaries, and open ocean.
Working along the coast for over 35 years means we know the tides, the regulators, the contractors, and the conditions — giving our clients an unmatchable local advantage from any point on the Pacific.
Whether you're at the planning stage or mid-project and need experienced eyes on a problem, Dees Marine Consulting is ready to help. We work with owners, contractors, agencies, and legal teams.
