1/9

Naver Bridge, Scottish Highlands

Asset Utilized:: Causeway Giant 1
Water Depth:: <5m
Solution:: Seas completed a challenging bridge site investigation in a remote location, overcoming dense gravels and boulders to 50m depth using advanced sonic drilling techniques. Careful planning, adaptable equipment, and trusted subcontractors enabled the safe delivery of the project ahead of schedule.
Location:: Scotland, UK

Dublin Metrolink

Asset utilized:: Sonic drilling, Geobore S
Solution:: Seas was appointed by TII on behalf of the National Transport Authority of Ireland to carry out ground investigation works for provision of geotechnical and environmental information to characterize ground conditions along the proposed route of this major infrastructure project.
Location:: Ireland, Dublin

3/9

Med Wind – Floating Wind Farm

Asset utilized:: Nautilus 1 Deepwater Drill
Water depth:: 900 m
Solution:: Seas used innovation sampling methods with our unique remotely operated systems to investigate the underwater environment. We deployed our robotic seafloor drill and cone penetration testing up to 40 meters below the seafloor, in water more than 900 meters deep.
Location:: Mediterranean Sea

4/9

Calero Reservoir

Asset Utilized:: Geoprobe
Solution:: Seas performed a comprehensive geotechnical investigation at Calero Reservoir, including borings, rock coring, in-situ testing, and instrumentation installation. The data provided a detailed understanding of subsurface and groundwater conditions, supporting infrastructure assessments and future reservoir rehabilitation efforts.
Location:: San Jose, CA

5/9

Railway Extension

Asset Utilized:: Terrasonic
Solution:: Seas completed a geotechnical investigation for the planned SMART rail station and infrastructure improvements, using multiple drilling methods to characterize subsurface conditions along the corridor. The resulting data supported project planning, design, and construction of the future rail extension and station.
Location:: Sonoma, CA

6/9

Port of Long Beach

Asset Utilized:: Quin Delta
Water Depth:: 15m
Solution:: Seas conducted an overwater geotechnical investigation from the R/V Quin Delta to characterize subsurface conditions beneath a major harbor. The resulting data supported foundation design, marine construction planning, and future waterfront infrastructure improvements.
Location:: Los Angeles, CA

7/9

Mediterranean Sea Site Investigation

Asset Utilized:: Nautilus 1 Deepwater Drill, CPT 1
Water Depth:: 4m - 1550m
Solution:: Seas deployed our seabed drill and seabed CPT to gather critical data for 190 floating turbine anchors and site to shore cable routes. Our equipment immediately showed its industry leading capabilities with 40m boreholes averaging 24 hours or less to complete and 8-12 seabed CPTs completed per day.
Location:: Offshore Italy

8/9

East Africa Site Investigation

Asset Utilized:: Nautilus 1 Deepwater Drill
Water Depth:: 50m - 2050m
Solution:: Seas deployed a seabed drill and seabed CPT to characterize seafloor and shallow subsurface conditions for a greenfield energy project in a geohazard-prone area. The program achieved industry-leading productivity, completing 10-12 CPTs per day in water depths up to 2,000m while delivering high-quality core recovery.
Location:: Offshore Mozambique

9/9

Offshore Guyana Site Investigation

Asset Utilized:: Nautilus 1 Deepwater Drill, CPT 1, Piston Corer, Box Corer
Water Depth:: 100m - 2080m
Solution:: Seas deployed a seabed drill, CPT with Ball Penetrometer, Box Corer, and Piston Corer to collect seafloor and shallow subsurface data for design and installation of subsea infrastructure, including FPSO moorings, flowlines, risers, and up to 60 subsea wells. Simultaneous vessel and equipment mobilization maximized efficiency and productivity.
