Work History

Surveyor/USV Operator/Quay Wall Cheif

Jan De Nul
04.2024 - 10.2025
  • Led hydrographic survey operations for quay wall construction, including crushed rock bed preparation and structural block placement
  • Conducted high-resolution MBES surveys using R2Sonic 2024 and Kongsberg EM2040 dual head systems for pre- and post-construction verification
  • Managed leveling tower operations equipped with rotating MBES, GNSS, and Total Station integration for real-time seabed profiling
  • Achieved ±1 cm positional and depth accuracy during rock leveling and leveling tower operations to meet strict design tolerances
  • Performed rapid MBES data processing within 10–15 minute operational windows to compare pre- and post-laying levels and guide construction decisions
  • Supervised critical block placement (A–H levels), achieving ±1 cm positional and depth tolerance to ensure stability and structural integrity of the quay wall foundation
  • Utilized instrumented block frames with dual GNSS, iXblue Octans motion sensor, and underwater cameras to provide real-time placement guidance
  • Delivered live survey data and visual feedback to crane operators and dive teams through Qinsy integration, improving placement accuracy and efficiency
  • Conducted post-installation surveys to determine block position and full orientation (roll, pitch, yaw, heading) and verified compliance with design specifications
  • Identified deviations from tolerance limits and reported to project management for corrective action
  • Overcame field challenges including line-of-sight obstruction, prism detection issues, and benchmark masking during Total Station operations
  • Performed shallow water surveys using USV where conventional survey vessels were not feasible, handling deployment, acquisition, and processing
  • Served as Rockworks Chief, processing Accropode placement data and verifying alignment and positional accuracy against design tolerances
  • Worked as Data Processor, performing QA/QC of multi-source survey data (rockworks, bathymetry, land survey), validating reports, and ensuring accurate data submission
  • Managed data backup and coordinated transfer of verified survey data to office teams for further analysis and reporting
