Offshore geotechnical site investigation in excess of 4000m water depth

Delivered with control and shaped by subsurface realities.

From seabed data to decisions teams can defend.

Seas Geosciences delivers integrated offshore geotechnical site investigations tailored to the unique water depths, metocean conditions, and seabed characteristics of each project providing clients quality, cost effectiveness and fast delivery of data and geotechnical engineering reports. Seas core offshore geotechnical services comprise of in-situ testing and sampling, in-situ instrumentation, advanced soil laboratory testing, and integrated data interpretive reporting.
Deepwater

Operations excellence offshore

Deepwater work demands deep expertise and advanced, purpose-built equipment that can perform reliably in extreme water depths, strong currents and often marginal sea states.

Seas’ drilling vessel is permanently configured with remotely operated, seafloor‑based drilling units for seabed and downhole geotechnical investigations in water depths from approximately 10m to beyond 4,000m. The Mako40 topside rig combines 4m heave compensation with exceptional operational versatility, enabling safe and efficient deployment of the optimal tool for a wide range of offshore conditions. Jumbo piston corers and piston corers can also be deployed through a dedicated launch and recovery system as well as box corers through the topside rig moonpool, enhancing safety during operations in marginal conditions.

  • Geotechnical and geophysical site characterisation
  • Foundation, mooring and cable route investigations
  • Early identification of geohazards
Shallow water and transition zones

Precision where conditions vary most.

Seas develops and deploys custom equipment, designed and built in-house, to exceed client expectation and project needs while maximizing productivity, increasing personnel safety and preserving the marine environment.

Disciplined execution. Adaptable methods. Reliable ground understanding.

  • We know the environments we work in don’t offer second chances, so we plan with that reality in mind.
  • Through Woocheen, we operate as part of a wider group focused on ocean health, water science and responsible marine development. We plan for the long term, take responsibility for the environments we operate in, and don’t cut corners when the work gets complex.
  • We take real pride in how the work gets done: collaboratively, carefully and with a clear sense of shared responsibility, so our clients can move their projects forward with confidence.

One measured approach from shelf to deepwater

Our one measured approach to project delivery combines customer focus, operational discipline, and data integrity. From coastal margins to ultra-deepwater campaigns, Seas applies the same evidence-led and data driven discipline.
