About the company
Kelson Marine Co, a Maine-based for-profit Subchapter S corporation, serves the federal government as a prime recipient of federal research grants and as a sub-recipient on research programs, with focus on marine renewable energy and offshore structural engineering. The vendor operates a lean federal footprint—three awards totaling $917 thousand obligated across 2021–2025, with only one prime grant award and two sub-award positions.
Kelson's single prime award is a cooperative agreement from the Department of Energy Advanced Research Projects Agency (ARPA-E) under the MARINER program, awarded December 21, 2021, with an ultimate completion date of June 20, 2025. The scope involves developing and validating a finite-element modeling tool (Hydro-FE) for hydrodynamic loading and structural analysis of ocean-deployed macroalgae farms using open-source solvers. Kelson transitioned from a sub-recipient position under the University of New England's MARINER Category 3 award to this standalone cooperative agreement, tasked with converting the proprietary codebase to open-source solvers, extending functionality based on farmer and regulator feedback, and conducting stakeholder outreach to classification societies (Lloyd's Register, American Bureau of Shipping), NOAA, and BOEM to establish regulatory frameworks for macroalgae farms. Deliverables include tutorial cases, publications, and workshops to disseminate the tool across the industry.
Kelson's two sub-award positions are recent. One sub-award, dated December 11, 2025, places Kelson as a sub-recipient under Texas A&M Engineering Experiment Station on a federal grant project titled "Safety Additions to FAST for Extreme Weather, Icing, and Nonlinear Dynamics (SAFE WIND)." A second sub-award, dated October 27, 2025, positions Kelson under The Southeast Conference for contracted support and analysis work. The Department of the Interior Bureau of Safety and Environmental Enforcement appears as a distinct customer agency, though the relationship basis is not specified in the source. Kelson's capability base centers on finite-element hydrodynamic modeling, offshore structural analysis, and macroalgae farm design optimization—a specialized niche within federal marine-energy research.
