Renewable energy

Vineyard Wind engaged COWI to support the development and delivery of the United States’ first large-scale offshore wind farm. The 800 MW project will deliver electricity to 400,000 households in Massachusetts.

COWI carried out due diligence of the Seaview Boatworks site in Bridgeport, assessing its suitability for turbine, platform, and transition piece storage and logistics. We assessed flood risk, water levels, live loading criteria, vessel types, and quay and upland requirements. As owner’s engineer, we also provided comprehensive services, including conceptual design of the full power system, electrical studies, tender preparation, EPCI package administration, and oversight of design, fabrication, and installation. 

COWI evaluated alternatives to coal and fossil-fuel energy systems at four US military installations, assessing renewable options including solar, wind, bioenergy, and geothermal.

Work included establishing baseline fossil fuel usage, developing clean energy replacement concepts, performing techno economic analyses, and recommending low-/no-emission solutions. COWI also contributed to environmental assessments (NEPA) for selected alternatives and provided feasibility and cost insights to support the Army’s transition toward clean energy.

Empire Wind is a major 2 GW offshore wind development off the coast of Long Island, New York. Powering one million New York homes, the project will help the state achieve its renewable energy goals. COWI is providing full lifecycle foundation engineering, including concept development, front-end engineering design, and detailed design for approximately 140 driven monopiles, supported by structural, electrical, and advanced geotechnical engineering.

Our services also included advanced geotechnical analysis, integrated load studies, installation engineering, and port and marine terminal assessments to support fabrication staging, operations and maintenance base siting, and landfall considerations.

COWI has been awarded the contract to deliver high-level design and construction supervision services for a new waste-to-energy facility at the Port of Bridgetown in Barbados. The project supports the port’s ambition to become a leading green maritime hub in the Caribbean.

Replacing the existing incinerator, the facility will use a modern wet-dry incineration system and a steam Rankine cycle turbine to improve energy efficiency and reduce emissions. Working with a global network of experts, COWI will help deliver an environmentally responsible solution for managing waste from cruise ships and port operations.

COWI is a trusted partner in planning, designing and delivering transportation infrastructure that strengthens connectivity and supports sustainable growth across North America.
