SPS Planning & Execution

Special Periodical Surveys are critical milestones in a rig's lifecycle. Navaleon manages the entire SPS process — from early planning through class certification — in close coordination with ABS, DNV, and Lloyd's.

We deliver:
• Pre-SPS inspections to identify defects before formal surveys
• Full scope of work development
• Class society coordination & certification management
• Yard selection & logistics
• On-site supervision & quality control
• Documentation & class handover

Control Systems & DCS Integration

The majority of rig reactivation failures are caused by control system issues. This is where Navaleon's expertise is most critical — and most distinctive.

We are integration specialists, ensuring seamless system performance across all rig control systems from day one.

Obsolescence Assessment
