GC-19 Boxer Flare Tower Removal

Removing the flare tower on GC-19 Boxer ahead of complete decommissioning

At Shell Gulf of Mexico, careful planning is integral to every project, especially when it comes to decommissioning the GC-19 Boxer platform. With a dedication to safety and efficiency, Shell recognizes the importance of preparing total facilities for decommissioning with precision.

Acknowledging the critical need to remove the flare tower before the heavy marine spread arrives, Shell entrusted Conbit with this vital task. Drawing upon our expertise in piece small removal methods, Conbit executed the operation seamlessly, employing a customized combination of lifting systems to ensure the safe and cost-effective removal of the entire flare tower.

Watch how we prepare and execute

The use of a floating gin pole in offshore decommissioning ensures safe and effective dismantling of lattice structures like flare towers.

Gantry lifting system

Conbit engineered a gantry system specifically tailored for lifting the heaviest components— the flare tip and molecular seal— during the removal of the flare tower. Prior to shipment to the US, rigorous load testing of the gantry was conducted at Conbit's facilities in the Netherlands to ensure optimal performance and safety.

Floating gin pole

A gin pole lifting system was employed to remove all smaller components of the flare tower. This lifting device, situated within the lattice structure, facilitated the creation of lift points maneuverable within the main structure during removal.

As with the gantry system, Conbit conducted rigorous load testing of the gin pole at its yard before shipment to ensure reliability and safety during operations.

Conbit Rope Access Crew

A proficient Conbit crew, comprising highly specialized technicians, was mobilized to the site to execute the project. This diverse team included both European and American rope access technicians, ensuring a comprehensive skill set for mechanical and rigging tasks. As the project extended beyond one rotation, multiple teams were deployed to maintain continuity and efficiency throughout the duration.

Smooth Flare Tower Removal

The removal of the flare tower proceeded smoothly, with the project completed within the planned timeline despite initial weather constraints affecting major lifts. The crew's adeptness in utilizing lifting systems alongside rope access and mechanical expertise ensured a safe execution. The client expressed high satisfaction with the overall outcome of the project, underscoring its success.

Conclusion

With the removal of the prominent flare tower, the skyline of the GC-19 Boxer platform undergoes a transformative change. The absence of this imposing structure alleviates concerns for heavy lift contractors, ensuring smoother operations during their campaigns. Conbit takes pride in the safe execution of the project, underscoring the efficacy of thorough preparation, and rejoices in the safe return of all involved.
