To meet growing client demands for integrated geophysical
and geological data recovery, EGS operates its own suite of
geotechnical coring equipment and Cone Penetration Test units
for ground truthing in nearshore and offshore environment.
EGS has steadily expanded its marine geotechnical capability to meet the increased demand for integrated geological and geophysical surveys from deep ocean to the water's edge, includin, seabed sampling, in-site resting and rock coring are carried out for:
Offshore equipment includes gravity and piston coring, and MCPT which can be operated to below 3,000m. Nearshore capability also includes vibrocoring, 10T capacity seabed CPT and rotary soil and rock drilling and in-situ testing from floating vessels or jack up barges, for the intertidal zones less than 30m water.
To meet growing client demands for integrated geophysical and geological data recovery, EGS operates its own suite of geotechnical coring equipment and Cone Penetration Test units for ground truthing.
Seabed and subsoil sampling provides geological samples required for geotechnical testing for engineering design as well as to ground truth geophysical survey results. Soil sampling also provides material for geochemical analyses for both exploration and environmental purposes. EGS successfully operates a number of seabed sampling and coring systems including:
EGS have carried out thousands of cone penetration tests (CPTs) across the globe. It is a cost effective method of measuring the geotechnical properties of the shallow seabed materials.
Equipment is mobilized to site efficiently through a modularized approach where either inshore survey equipment is compact enough to be air freighted, or the larger offshore equipment together with offices, laboratories and workshops are containerized for shipping.
EGS also owns standard 3m push, 100KN seabed CPTs with 10cm2 cones and 3m push sampler to 3,000m, and up to 30m push in nearshore conditions.
Parameters measured by the CPT are:
Subsea Seabed Samples Classification
Box Coring Project
Getechnical Barge Mobilization
The co-operation and working relationship between all parties during all phases of this project has been a text book example of how to conduct survey operations etc.Holland, Geoff
I just wanted to take the opportunity presented by the end of survey data acquisition activities to say thank you and well done on the excellent performance of the EGS team through the execution of the works to date. Whilst I’m mindful that there is still much to do in terms of tide gauge recovery, data processing and deliverable preparation – the performance of all personnel involved to date from EGS and Broadsword has been exemplary and particularly, the professionalism and attention to detail of the site team. It’s also been particularly pleasing to see this complicated and challenging scope completed in such a competent and hassle-free manner.Rhys Jones
I would like to thank you for this excellent survey. Your team was professional and knowledgeable. It was a pleasure to work with them.Philippe Hubert
On behalf of TOTAL E&P PNG and InterOil, we would like to express our gratitude for the efficient operation of the survey as well as safe and timely return to Port Moresby. It was a pleasure working with you all on the ground. We wish you all the best in your future endeavors.Anton A Safronov
