Rope Access Inspection & Maintenance On Jack-Up Rig Dixtone Legs | Lamprell Yard UAE.
EXECUTIVE SUMMARY
This case study highlights the successful execution of surface preparation and coating works on the jack-up leg structures of Rig Dixstone during its refurbishment at Lamprell Yard in 2025. The project involved comprehensive surface preparation, including degreasing, high-pressure washing, mechanical cleaning, and the application of a high-performance protective marine coating system.
These activities were undertaken to ensure long-term corrosion protection, maintain structural integrity, and comply with offshore coating standards for harsh marine environments. All work was completed under the strict supervision of Lamprell’s QA/QC team and the client’s quality inspectors, ensuring full compliance with international coating standards and dry film thickness (DFT) requirements.
SCOPE OF WORK
As part of the rig maintenance and painting project, the following activities were completed
- Asset: Jack-Up Rig – Leg Structure
- Spot surface preparation using mechanical cleaning and touch-up primer application on corroded or exposed steel surfaces.
- Full coat protective painting applied across the entire designated surface area.
- Quality inspection and control by Lamprell QA/QC and client-side inspection teams.
- Strict adherence to coating system specifications and DFT compliance to ensure long-lasting corrosion protection.
METHODOLOGY
Surface Preparation:
• Mechanical surface cleaning following (ST2/ST3) to remove rust, scale, and contaminants.
• Degreasing and high-pressure (HP) washing to ensure a clean substrate for optimal coating adhesion.
Coating System:
• Primer: One spot coat applied to localized areas requiring corrosion protection.
• Final Coat: One full coat applied to the entire prepared surface, ensuring a uniform protective barrier.
Tools & Equipment Used:
•Brushes and rollers for precise coating application.
•Elcometer 456 DFT gauge for accurate dry film thickness measurement.
Standards Followed:
• Client-specific coating specifications.
• Lamprell QA/QC inspection procedures.
CHALLENGES & SOLUTIONS
The project faced environmental challenges such as:
• High wind speeds and unfavorable weather conditions that impacted the painting schedule and surface preparation quality.
Control Measures Implemented:
• Continuous weather monitoring to identify safe working windows.
• Strict application of Safe Work Permit procedures to ensure painting activities were conducted under optimal and safe conditions.
proactive steps ensured both worker safety and coating system performance without compromising project timelines.
INSPECTION & RESULTS
• All industrial painting and inspection activities were executed in coordination with:
Lamprell QA/QC Inspectors
Client’s quality assurance team
• Dry Film Thickness (DFT) readings were consistently verified using calibrated instruments, ensuring values remained within the approved coating specification range.
• Final visual inspections confirmed a defect-free finish.
• The project was completed and approved without any need for rework.
CONCLUSION
The protective painting works on Rig Dixstone, jack-up leg, including a spot primer coat and a full topcoat application, were successfully executed and completed with zero tolerance for defects. Every stage of the project underwent thorough inspection and was fully approved by both Lamprell’s QA/QC team and the client’s quality inspectors. Despite facing challenging weather conditions, the team ensured that all activities met the required coating specifications, including precise Dry Film Thickness (DFT) readings and compliance with technical standards. The project was completed on time, to the highest quality standards, and was officially closed with full client satisfaction and approval.
