Client: Major International Operator – Gulf of America
Challenge
The operator required a comprehensive underwater maintenance program for all its offshore assets in the Gulf of America to uphold safety and environmental integrity. The scope was vast, involving over 1,100 offshore structures, with strict constraints: no disruption to ongoing production or drilling, zero safety incidents, and adherence to environmental protection standards.
Solution
Avantex led the planning and execution of a multi-year underwater inspection program. Key elements included:
Designing and deploying a rotational inspection schedule for 1,100+ assets.
Developing a custom digital system to manage and analyze the large volumes of inspection data.
Coordinating with multiple subsea contractors and vessel/diver teams annually.
Managing logistics to avoid any impact on ongoing production and drilling activities.
Executing all diving operations—some at depths of up to 600 feet—with strict adherence to safety protocols.
Added Value
Delivered the full program scope on time and under budget.
Enabled critical underwater repairs based on inspection results.
Maintained continuous production and drilling operations throughout.
The program’s success contributed to the formulation of US Department of the Interior’s underwater inspection guidelines.
