Delivered safely through flexible seabed CPT, seismic CPT, sampling, coring, laboratory testing and geotechnical interpretation.
Geoquip Marine delivers seabed and shallow geotechnical services, providing reliable near-surface and deepwater seabed data to complement our drilling-led site investigation capabilities and support engineering design, installation planning and geotechnical risk management.
From shallow-water environments to deepwater locations, our seabed testing and sampling capability enables efficient, targeted data acquisition wherever accurate seabed characterisation is essential.
Our integrated approach combines seabed in-situ testing, sampling and coring with offshore operations, laboratory testing and geotechnical interpretation, supporting informed decision making throughout the project lifecycle. From early scoping, our team works with clients to define investigation requirements, advise on the right technical approach, and deliver the safe, reliable data their projects depend on.
Geoquip Marine continues to invest in seabed geotechnical technology, including deepwater CPT systems, integrated seismic capability, combined coring systems and penetration enhancement development. With in-house engineering design and development teams, we can also provide bespoke solutions for specialist mobilisations and operational requirements.
Seabed cone penetration testing (CPT) and piezocone penetration testing (PCPT) provide detailed insight into soil type and behaviour, with operations delivered in line with international standards including ISO 19901-8 and ISO 22476-1. Our deepwater systems are rated to 2,000m water depth and ready for rapid mobilisation, our in-house engineering team can also develop bespoke systems for projects requiring greater depths.
Our seabed CPT systems can be deployed with integrated seismic modules to acquire S-wave and P-wave data alongside conventional CPT parameters, with paired receiver sets enabling true interval interpretation for foundation design and installation planning.
Box corers, grab samplers, vibrocorers and piston corers enable the recovery of seabed and shallow sub-seabed samples, extended through trusted partners where projects require specialist techniques.
Container-transportable systems deploy from Geoquip Marine vessels, charter vessels and partner platforms, matching the right technical solution to each project’s location, water depth and schedule.
Offshore laboratories, our UKAS-accredited onshore laboratory and in-house geotechnical interpretation combine field data, laboratory results and engineering insight into fully integrated reporting.
Depending on project scope, deliverables may include seabed CPT and PCPT data, seismic CPT results, sample logs, laboratory outputs, geotechnical interpretation and integrated reporting.
Investigation objectives, locations, soil conditions, water depth, deliverables and project constraints are reviewed to define the most appropriate seabed testing and sampling approach.
Seabed geotechnical equipment is mobilised on Geoquip Marine vessels, charter vessels or partner platforms, with operations planned for safe and efficient offshore delivery.
Experienced offshore teams deliver seabed testing and sampling with continuous monitoring, quality control and technical support, maintaining data integrity throughout the investigation.
Results are processed offshore and onshore, providing timely inputs for geotechnical interpretation, design development and final reporting.
Fixed and floating wind, from early development through construction.
Field infrastructure, carbon capture and storage, and hydrogen.
Export cables, interconnectors, telecoms cables and power transmission routes.
Ports, land reclamation, nearshore works and seabed developments.
Subsea data centres, seabed plant and equipment, and new offshore infrastructure.
Combined geotechnical, geophysical and environmental programmes.
