Eastern Shipbuilding Group announced the successful completion and redelivery of HOS Rocinante, a first-of-its-kind U.S.-flagged Commissioning Service Operation Vessel (CSOV) converted for Hornbeck Offshore Services. The project represents a significant milestone in the continued evolution of the U.S. offshore service fleet toward future-ready, for the offshore wind, oil and gas sectors
Originally built by Eastern Shipbuilding Group as an offshore supply vessel, the HOS Rocinante has undergone an extensive conversion at Eastern Shipbuilding’s Allanton and Port St Joe Shipyards in Panama City, Florida. The project transformed the vessel into a next-generation CSOV engineered to support technician accommodation, safe personnel transfer, and multi-day offshore operations in harsh, open ocean environments — capabilities essential for offshore wind farm construction and maintenance, as well as traditional offshore energy projects.
Commissioning Service Operation Vessel HOS Rocinante‘s Key conversion elements include:
- Installation of a walk-to-work motion-compensated gangway and other personnel transfer solutions
- Enhanced dynamic positioning (DP) and propulsion capabilities for precise station-keeping
- Upgraded accommodation and workspace capacity for offshore technicians with single person staterooms
- Significant improvements to cargo handling and client warehousing/storage systems
- Energy storage system for enhanced power reserve and improved failure mode operability
“This is a full circle moment for our team to be able to convert a vessel that we built more than ten years ago. The delivery of the HOS Rocinante demonstrates what American ingenuity and skilled labor can accomplish,” said Joey D’Isernia, CEO of Eastern Shipbuilding Group. “This vessel is now one of the most capable multi-market offshore support assets in the U.S. fleet, built right here on the Gulf Coast by America’s best shipbuilders.”
The CSOV is uniquely positioned to support both offshore wind development,offshore wind, oil and gas operations, offering Hornbeck Offshore Services unmatched flexibility to meet the evolving needs of domestic and international energy customers.
The project supported hundreds of skilled jobs at Eastern’s yards and throughout its Gulf Coast supplier network and reinforced Eastern Shipbuilding Group’s leadership in high-complexity vessel construction and conversion.
