Case Study: Full Dimensional Control Survey on LDD offshore shroud for TEXO
Client: TEXO
Project Location: CTL Seal Fabrication Facility, Sheffield
Project Start Date: 20/09/2023
Project Objective:
To perform precise dimensional control measurements on specified drill bit components in accordance with drawing 0400-00036. This included the extended upper arm, gauge cutter, and extended roller arm at predetermined set locations of 8000mm, 8500mm, and 8750mm.
Equipment Used:
Leica MS60 MultiStation: n advanced total station providing high-accuracy measurements with integrated scanning and imaging capabilities.
Bohnenstingl Prisms:High-precision prisms used for accurate distance measurement and alignment.
Scope of Work:
Preparation and Planning:
Review and understand the marked-up drawing provided - 0400-00036.
Coordination with CTL/LDD to confirm and extend the set locations before survey work commenced.
Set up a detailed survey plan outlining all necessary equipment and methodologies to ensure accuracy.
Site Setup:
Establish a secure and stable base for the Leica MS60 to avoid any potential disturbances during the measurement process.
Position Bohnenstingl prisms at designated points for precise alignment and measurement.
Measurement Procedure:
Use the Leica MS60 to measure the dimensions of the drill bit components at the set locations of 8000mm, 8500mm, and 8750mm.
Follow the dimensional control specifications outlined in the drawings to ensure all measurements adhered to specified tolerances.
Record measurements accurately and verify against the predefined specifications.
Data Validation and Reporting:
Cross-check measurements with initial design requirements.
Prepare a comprehensive report detailing all measurements taken, including any deviations from the specified dimensions.
Provide recommendations for any necessary adjustments or re-measurements to ensure compliance with project requirements.
Results:
The dimensional control survey conducted by RSL provided precise measurements for the drill bit components. The use of the Leica MS60 and Bohnenstingl prisms ensured high accuracy, meeting TEXO's stringent requirements. Any discrepancies found were minimal and within acceptable tolerances, demonstrating the effectiveness of the equipment and methodologies used.
Conclusion:
RSL successfully completed the dimensional control survey for TEXO at the CTL Seal Fabrication Facility. The accurate and reliable data collected facilitated the proper alignment and fabrication of the drill bit components, contributing to the overall quality and integrity of the project. This case study highlights the importance of precise measurement tools and thorough planning in achieving successful survey outcomes.
Outcome:
• The critical role of pre-survey coordination with (CTL/LDD) to confirm and extend set locations. • The importance of using high-precision equipment like the Leica MS60 and Bohnenstingl prisms to achieve accurate results. • The necessity of thorough data validation and reporting to ensure compliance with design specifications and project requirements.
This case study serves as a testament to RSL's expertise in providing high-accuracy survey services in complex industrial environments.
