HYDRA executed a subsea intervention campaign in the Gulf of America. The team successfully completed tether installation, subsea tree remediation, and manifold valve operations in approximately 2,000 feet of water.
A key highlight of the campaign was the successful installation of a replacement buoy tether system using ROVs alone, demonstrating HYDRA’s capability to execute complex installation work without diver intervention.
HYDRA was contracted to execute a multi-scope subsea campaign that included:
Supporting activities included subsea disconnection and reinstallation of flowline control components, deployment and recovery of subsea structures, and completion of arrival and as-left surveys. All work was performed using work-class ROV systems to enable precise subsea manipulation and installation.
The campaign required execution of multiple work scopes within a single offshore window, demanding tight coordination between vessel operations, ROV teams, and project personnel. Variable weather conditions reduced available work windows and required adaptive offshore planning.
Additional challenges included working within confined subsea geometries, handling flexible tether materials during installation, and performing precision leak remediation on existing infrastructure—all while maintaining steady operational progress in a deepwater environment.
HYDRA delivered this project through a fully integrated offshore execution model, combining vessel operations, ROV intervention, and project management into a single, cohesive solution. By executing multiple scopes within one campaign, HYDRA eliminated the need for multiple mobilizations and reduced overall project risk.
The project also demonstrated HYDRA’s advanced ROV capabilities, successfully completing a tether installation scope that was initially considered challenging without diver intervention. HYDRA’s experienced offshore personnel maintained strong operational discipline and delivered efficient execution aligned with client objectives.
