Marine Construction

Understanding the Marine Environment for Offshore Operations

Offshore wind, coastal engineering, port development and construction depend on a clear understanding of waves, currents and turbulence. Reliable measurements support site assessment, engineering decisions and the safe management of offshore operations.

How General Oceans delivers:
General Oceans' companies provide Acoustic Doppler Current Profilers (ADCPs) and configurable ocean buoy systems for measuring currents, waves and other environmental conditions. Systems can support both short-term surveys and longer-term monitoring programmes.

Relevant capabilities:
ADCPs, current profiling, directional wave measurement, turbulence measurement, real-time ocean data, vessel-mounted and buoy-based deployments.

Inspecting and Maintaining Subsea Assets

Submerged structures must be inspected and maintained in environments where visibility, access and water movement can make operations difficult. Operators need dependable ways to assess the asset's condition and undertake practical work below the surface.

How General Oceans delivers:
General Oceans companies provide imaging sonar for inspection and situational awareness in low visibility, alongside electric robotic manipulators for inspection, maintenance and intervention from ROV platforms.

Relevant capabilities:
Multibeam imaging sonar, mechanical scanning sonar, electric manipulators, non-destructive testing support, cleaning and cutting tools, payload and ROV integration.

Surveying the Seabed and Infrastructure Routes

Offshore developments require detailed knowledge of the seabed before infrastructure is installed. Survey teams need to identify seabed features, objects and potential hazards while collecting information suitable for planning and further investigation.

How General Oceans delivers:
General Oceans companies provide high-resolution side scan sonar for route surveys, seabed characterisation and hydrographic or geophysical work. Selected systems also support bathymetric data collection and autonomous underwater vehicles.

Relevant capabilities:
Side scan sonar, swath bathymetry, route survey, seabed characterisation, hydrographic and geophysical survey, AUV and UUV integration.

Subsea Navigation and Positioning

Our companies provide Doppler Velocity Logs (DVLs), inertial navigation support and forward-looking sonar for underwater vehicles and construction platforms. Integrated navigation and imaging help operators track movement, maintain position, identify obstacles and work with greater confidence when satellite positioning or optical visibility is unavailable.

Subsea Imaging

Side scan and multibeam imaging sonar reveal seabed features, submerged structures and potential hazards, even where visibility is limited. These technologies support site surveys, asset inspection, construction monitoring and situational awareness across marine construction projects.

Underwater Robotics

Portable ROV/AUV platforms and electric manipulators extend inspection and intervention capability beneath the surface. Integrated imaging, navigation, tooling and payloads enable operators to inspect assets and complete practical tasks remotely in challenging or hazardous environments.

Underwater Intelligence

General Oceans technologies capture and interpret data from across the underwater environment. By bringing together sonar imagery, environmental measurements and information from robotic platforms, our companies help teams build situational awareness, monitor changing conditions and make informed operational decisions.
