What is Offshore Surveying?
Offshore Surveying is concerned with meeting the surveyrequirements of the offshore industry. Broadly speaking, these
are:
the positioning of vessels, drilling ships, platforms, etc the surveying of seabed and sub-seabed features prior to
the installation of rigs, platforms, pipelines, etc
the ongoing inspection of installations
What does the Energy Industry do?
Oil & Gas Life Cycle
Offshore Surveying plays a major contribution in theexploration and appraisal for, development of, andproduction from oil and gas fields around the world:
Exploration
Locating oil and gas via seismic acquisition process is reliant on various forms of offshoresurvey and positioning: 2D seismic single streamer 3D seismic multiple streamer 4D seismic time lapse survey
Appraisal Exploration and Appraisal Drilling the precise positioning of
rigs and anchors in the correct places
Mobile rigs comprise of two types:
Jackup rigs: Shallow water (
Field Development From Plan to Reality requires many forms of survey and
precise positioning:
Production Inspection, Repair and Maintenance (IRM) surveyors play
key role in the integrity of equipment and facilities: Acoustic pipeline inspection
Remote Operated Vehicle (ROV) pipeline inspection
ROV structural inspection
Inshore pipeline inspection
Diver repairs
Decommissioning
Installations:
Positioning and navigation support
Pre decommissioning surveys
Hazard notification
Post decommissioning surveys
Updating of infrastructure databases
Pipelines and Cables:
Positioning and navigation support
Monitoring adjacent infrastructure integrity
Post decommissioning survey inspection
Updating of infrastructure databases
