Project Background
3S Engineering undertook a project to monitor the structural integrity of the Anoa and AGX platforms, operational since 1990 and 2001, respectively. The aim was to assess subsidence parameters to ensure safe and cost-effective operation.
Methodology and Approach
The project employed a range of geodetic and geotechnical tools, including GPS receivers, tilt meters, accelerometers, and water level sensors. Measurements focused on natural period, tilt, air gap, water depth, and positional data, with ten measurements conducted for data accuracy.
Challenges
Accurately modeling the interactions between the platform structures and the seabed, considering operational changes over time, was a challenge. Consistent measurement points for future monitoring and dealing with remote environmental conditions added to the complexity.
Outcome
The project established baseline subsidence parameters for both platforms, including natural period frequencies, tilt angles, air gap measurements, and water depth. These parameters are essential for ongoing structural integrity management, enabling early detection of potential issues and informed maintenance decisions.
Collaboration and Compliance
3S Engineering collaborated with Harbour Energy and adhered to industry standards, including ASME and SNI regulations. Advanced fiber optic measurement techniques and GPS data ensured precision and safety compliance.
Key Messages
This project demonstrates 3S Engineering’s capability in utilizing advanced technologies for structural monitoring of offshore platforms. The successful implementation of this monitoring program enhances the safety and longevity of these critical energy infrastructures.
