Dimensional control of subsea structures and onshore construction components

EGS offers both terrestrial and subsea laser scanning. Dimensional Control and monitoring services, utilizing proven engineering survey techniques and modern survey equipment , can provide substantial benefits to any project both onshore and offshore.

Dimensional control applications:

  • FPSOs, TLPs, SPARs, Semi-subs, Jackets, MinDocs, Compliant Towers, Onshore
  • Pre-fabrication of Hook-up Spools
  • Like-Kind replacement of Equipment and Piping with complete 2D/3D detail drawings
  • Fabrication verification surveys for steelwork and pipe
  • Clash/Interference surveys for the replacement or installation of mechanical components
  • Deformation Analysis
Key project benefits from implementing Dimensional Control Survey management include:
  • Reduced design, re-work and shutdown times
  • Reduction of man-hours in potentially hazardous areas and activities
  • Guaranteed fit of pre-fabricated items
  • Elimination of multi-handling of components
  • Availability of archived data
  • Elimination of re-design during installation
  • Minimize fit-up issues that result in schedule/budget overruns

LBL Subsea Metrology

Long baseline (LBL) positioning has many applications both commercially and in research, from surveying a ship hull to positioning offshore platforms in deeper waters. The technique consistently provides accuracies in the order of decimetres over large areas, independent of depth. Recent advances include the integration with other acoustic techniques or with inertial navigation systems for greater levels of accuracy.

EGS provides the following LBL metrology services:

  • Array planning
  • Frequency planning
  • LBL calibration
  • High accuracy subsea installation and ROV tracking
  • Spool tie-in
  • Inertially aided acoustic subsea positioning
  • Provision of ISO drawings

In the ever demanding Oil & Gas sector, EGS offers bespoke reporting services, including near real-time offshore delivery by integrating data processing with charting facilities onboard.
