• 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

• 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
