Geophysical Surveys
Geophysical data provides vital information on the geology of the sub-bottom strata, required for any engineering,
construction, drilling, production or mining activity.
Detailed geophysical surveys and assessments of the seabed and sub-seabed are critical to de-risking the cost-effective design of marine structures and subsea installations.
Fugro’s strategically-located geophysicists, marine biologists, environmental scientists, engineers and specialists deploy an international fleet of geophysical survey vessels, AUVs, seabed sampling and testing tools and LIDAR equipment to provide our customers with high quality data acquisition, interpretation and presentation.
Geophysical Surveys
Fugro’s international fleet of strategically located geophysical survey vessels
and geohazard specialists provide high quality geophysical data acquisition and
interpretation services.
These include:
- Bathymetric charting of the sea floor for safety-critical and engineering applications
- Locating and identifying man-made artifacts such as debris, shipwrecks and sub-sea structures
- Profiling shallow geological features and structures to assist with engineering studies and facilities design
- Seabed and sub-surface geotechnical assessments
- Locating and identifying geohazards to ensure safe and efficient exploration drilling, facilities installation and production operations
Our comprehensive desktop study and geoscience consulting services integrate all
available data. Included are 3D exploration seismic data, legacy geophysical data,
geotechnical data and project specific acquired data. These are used for detailed
engineering design and environmental risk analysis of the project.
Data processing, interpretation and presentation services then provide our clients with
results in quality-assured formats, including concise reports and traditional paper charts
which are also available in digital formats.
Inspection Surveys
Pipeline inspection surveys to detect free-spans, damage, defects, leaks, erosion or pipeline movement, require innovative technology and experience.
Fugro’s highly skilled team is supported by a fleet of dedicated geophysical, acoustic survey and ROV/ROTV inspection vessels offering clients the most comprehensive range of solutions.
Pre-installation Surveys
A survey and seabed inspection, performed shortly before the start of engineering work, can help to ensure that the work area is properly prepared.
This means not only clearing away obstructions, but correctly locating and identifying potential operational hazards.
Deep-water Field Developments
A survey and seabed inspection, performed shortly before the start of engineering work, can help to ensure that the work area is properly prepared.
This means not only clearing away obstructions, but correctly locating and identifying
potential operational hazards.
A strategically-deployed fleet of Echo Class autonomous underwater vehicles (AUVs)
provides engineering-grade precision survey data for the development of deep-water
oilfields and the installation of transmission pipeline systems in water depths down to
3,000 metres.
The high resolution of such data and the precision with which it is coupled with the
seabed, enables confident geohazard risk assessments of a deep-water development
and its geological setting.
Geohazard Surveys
Fugro supports safe exploration and production activities by providing high resolution geophysical surveys using HR2D and Short Offset HR3D techniques.
These identify and map geohazards that could impact on the safety of drilling or installation operations.
These include shallow gas, active faulting zones and areas of potential hydrates. A
combination of high resolution geophysical surveying and geotechnical investigation
provides further information on seabed conditions to aid in predicting jackup leg
penetration and anchor holding capacity for foundation engineering studies.
subsea cables.
Shallow Target Exploration Seismic Surveys
Fugro’s expertise in the acquisition of high resolution seismic data is ideally
suited to seismic exploration surveys where the depth to the zone of interest
is less than 3 kilometres.
These surveys can be undertaken using dedicated Fugro survey vessels or vessels
of opportunity, each equipped with field proven and reliable mobile acquisition
systems. High resolution seismic sources and processing systems provide data of
the highest quality which, after processing, can deliver 3D volumes for standard
work station interpretation.
Pipeline Route Surveys
Detailed corridor mapping provides the essential raw data for the design and`installation of sub-sea linear structures, such as oil and gas pipelines, flow lines and umbilicals.
Seabed sampling and testing tools - such as grab samplers, vibrocorers and Cone
Penetrometer Testing (CPT) units - can be combined with high resolution seismic
and geophysical data to provide accurate information on the structure of the
seabed. This data is essential for providing a correctly engineered design
that avoids the often considerable costs associated with overengineering for
uncertainties.
Environmental Surveys
Offshore oilfield and civil engineering activities around the world require
stringent pre- and post-activity baseline assessments to confirm that developments
will not adversely impact the environment.
Fugro’s team of highly skilled marine biologists and environmental scientists
acquire high resolution images of the seafloor and associated benthic communities,
and conduct systematic sampling programmes using a variety of devices.
Data is then analysed at our NMBAQC-approved laboratory and comprehensive
reports are prepared.
Renewables, Port and Coastal Surveys
We provide a range of specialist survey vessels, compact AUV systems and
expert teams to meet the requirements of the renewable energy industry and
the port and coastal engineering community.
These are used to deliver services such as:
- Hydrographic surveys
- Navigation and conservancy surveys
- Surveys and support services for dredging works
- Monitoring services for beach and foreshores, sediment movement and material recycling
Mineral Surveys
The exploration for valuable seafloor minerals demands leading-edge technology.
Fugro’s high-resolution AUVs and other geophysical systems, combined with
geotechnical sampling programmes, provide the deep-sea mining industry with
detailed and comprehensive views of ocean floor structures and surface texture in
order to assist with the identification of mineral deposits and the design of optimal
recovery solutions.
Charting and UNCLOS Surveys
Detailed charts of the seabed and sub-seabed geophysical information aid
the evaluation of precious national assets and the definition of international
maritime boundaries.
Fugro’s fleets of survey vessels, autonomous underwater vehicles and SHOALS
LIDAR aircraft are equipped with the latest technology to provide a comprehensive
seabed charting service at scales suitable for all applications. This includes
Exclusive Economic Zone (EEZ), UNCLOS Article 76 assessments and
bathymetric charting surveys.
