Hydra supported offshore decommissioning operations in the Green Canyon area by providing an integrated vessel, ROV, and diving solution to prepare a fixed platform for removal. Operating in a SIMOPS environment, Hydra coordinated ROV and diver activities to safely cut and remove structural members, pipelines, and appurtenances required for topside removal.
A key aspect of the project involved preparing the structure for partial removal, enabling the upper 90 feet of the platform to be removed while leaving the remaining jacket in place as an artificial reef. This approach balanced safe decommissioning execution with environmental stewardship, contributing to long-term marine habitat development.
Hydra was contracted to provide a DP II MPSV with ROV and dive support for platform removal preparations. The scope included:
The project required close coordination between vessel, ROV, and dive teams to safely execute concurrent offshore operations.
The project was executed in a SIMOPS (Simultaneous Operations) environment, requiring tight coordination between divers and ROV personnel working on the same structures. Maintaining clear communication, task separation, and situational awareness was critical to ensuring safe execution.
Cutting operations on aging offshore infrastructure introduced variability in material condition and marine growth, requiring pre-cleaning and adaptive tooling selection. Additionally, the integration of multiple contractors (dive teams, crane operators, and tooling specialists) required disciplined offshore management to maintain efficiency.
Hydra delivered a fully integrated offshore execution model, combining vessel operations, ROV services, dive support, and project management under a single operational framework. This integration enabled efficient SIMOPS execution and minimized downtime between tasks.
Hydra’s ability to coordinate multi-disciplinary offshore teams ensured safe and productive operations throughout the campaign. The team’s experience in both subsea intervention and construction support positioned Hydra to effectively manage the complexities of decommissioning work scopes.
