Sarens Nears Completion of Major Coastal Virginia Offshore Wind Project

Sarens is entering the final phase of its work on the Coastal Virginia Offshore Wind (CVOW) project, one of the largest offshore wind developments in the United States. The heavy lifting specialist has played a key role in the onshore marshalling and engineering operations at Portsmouth Marine Terminal since 2023.

30-Second Takeaway Sarens is nearing completion of its extensive work on the Coastal Virginia Offshore Wind project after managing large-scale marshalling and heavy lifting operations since 2023. The project involved handling hundreds of monopiles and transition pieces, complex SPMT transport operations, and major offshore substation components while meeting strict environmental and scheduling requirements. Sarens Advances Final Phase of Coastal Virginia Offshore Wind Operations Heavy lifting and engineered transport specialist Sarens is approaching the final stage of its work on the Coastal Virginia Offshore Wind (CVOW) project, one of the largest offshore wind developments currently underway in the United States. Since operations began in 2023 at Portsmouth Marine Terminal, Sarens has been responsible for the onshore marshalling and engineering scope on behalf of Virginia International Terminals. The project represents a major milestone in the continued expansion of offshore wind infrastructure along the U.S. East Coast. Large-Scale Offshore Components Required Complex Handling Operations The scale of the CVOW project required extensive heavy lifting, transport coordination, and engineering support throughout the marshalling campaign. Sarens Managed Hundreds of Offshore Wind Components The company handled: 176 monopiles 176 transition pieces Pin piles Installation templates Three offshore substation topsides Each offshore substation topside weighed approximately 4,000 tonnes, requiring highly coordinated lifting and transport operations. Intensive Operations Demanded Long-Term Efficiency To maintain operational productivity over the extended project duration, Sarens implemented several engineered handling solutions designed to improve safety, accessibility, and operational consistency. The project required a sustained high-volume operational approach across both lifting and transport activities. Engineered Steel Supports Improved Operational Efficiency One of the project’s key innovations involved the use of specially engineered steel support systems for monopile handling. Custom Support System Enhanced Accessibility and Stability According to Sarens, the engineered supports allowed full accessibility to the monopiles while also meeting strict ground-bearing pressure requirements across the terminal site. The solution improved operational workflow and helped maintain schedule reliability throughout the project. Ground-Bearing Requirements Critical for Heavy Offshore Components Given the extreme size and weight of offshore wind components, managing ground loads and operational stability formed a critical part of the engineering strategy. The custom support systems enabled safer and more efficient storage, handling, and mobilisation activities across the terminal operations. Hundreds of SPMT Movements and Heavy Lifts Completed The overall campaign involved an intensive series of transport and lifting operations throughout the marshalling programme. SPMTs Played Central Role in Component Handling Sarens completed approximately: 740 self-propelled modular transporter (SPMT) movements 382 lifts using a Liebherr CC8800 crawler crane These operations supported the movement, positioning, and load-out preparation of offshore wind components before transport to installation vessels. Liebherr CC8800 Supported High-Capacity Lifting Operations The Liebherr CC8800 crawler crane handled many of the project’s heaviest lifts, including major offshore infrastructure components and substation topsides.The crane’s high lifting capacity and stability were critical for maintaining operational efficiency across the demanding offshore wind campaign. Environmental Restrictions Added Additional Project Complexity Environmental regulations also played a major role in the scheduling and execution of offshore installation activities. Offshore Piling Subject to Whale Migration Restrictions Offshore piling activities had to be completed outside restricted environmental windows linked to whale migration activity along the U.S. East Coast. These regulations created strict operational deadlines for offshore installation work. Early Completion Helped Avoid Project Delays Through close coordination between project stakeholders, all monopile installation activities were completed one month ahead of the required deadline. This early completion helped avoid scheduling disruptions and ensured continued project progress. Final Transition Piece Operations Now Underway As of March 2026, Sarens confirmed that only ten transition pieces remain to be handled before completion of the project’s load-out activities. Project Nearing Completion After Multi-Year Campaign The nearing completion of the marshalling scope marks a significant milestone in one of the largest offshore wind infrastructure programmes currently under development in North America. The CVOW project continues reflecting growing investment in large-scale renewable energy infrastructure and offshore wind capacity across the United States.
