Geophysical Site Survey

Geophysical data provides vital information on the geology of the sub-bottom strata, required for any engineering, construction, drilling, and production and mining activity. Detailed geophysical surveys and assessments of the seabed and sub-seabed plays a decisive factor in reducing the risks and make them cost-effective design of marine structures and subsea installations. Geophysical site survey is often conducted when a jack-up rig wants to approach to the platform and this operation ensures the client about seabed obstructions and geology of the seabed.

What are we trying to find out through a geophysical site survey?
  Water depth, seabed relief, seabed gradients
  Obstructions, debris, wrecks, existing installations
  Seabed sediment types
  Shallow water geology, foundation conditions, trenching conditions
  Geo-hazards such as shallow gas
The results of site survey operation include:
  Bathymetry charts in the site location
  Seabed feature charts (which shows the location of obstruction on the seabed)
The results of geophysical site survey are shown in the following reports and charts:
  Final text reports “Geophysical site survey report”.
  Bathymetric charts that all of depths reduced to LAT
  Seabed feature.
