Offshore Geotechnics
Horizon performs detailed offshore geotechnical investigations to support the design, engineering and installation of the following offshore structures:
-
Foundations for piled jackets, gravity based structures and FPSO
Jack-up rigs
Jackets and platforms
PLEM and SPMs
Wind Turbines
Pipeline and cable routes
Suction and drag anchors
We have a fleet of offshore drilling rigs which can be operated from our dedicated drill ships and can also be mobilised onto vessels of opportunity or client supplied vessels allowing worldwide operations.
All offshore geotechnical investigations are conducted from our heave compensated drilling rigs with a wire line system including downhole Wison-APB cone penetration testing (PCPT) and in-situ vane testing equipment. Mud mix and transfer systems control borehole stability while fully equipped offshore soil testing laboratories provide in-field analysis.
Our offshore geotechnical spreads are equipped for:
-
Undisturbed and disturbed soil sampling
Rock coring
Downhole PCPT testing
Seismic CPTs
Downhole vane testing
P-S logging
In-field soil laboratory testing
200kN seabed CPT system
40kN Roson seabed CPT system
Horizon’s offshore geotechnical capabilities are supported by our onshore team of experienced geologists and geotechnical engineers whom utilise the data gathered offshore and in the laboratory for detailed interpretation of the foundation design and engineering analysis.
We review the information gathered from offshore geotechnical investigations with desktop studies and geophysical data to supply an integrated report to the client.
