Subsea Instrumentation, Security and Monitoring / Underwater Works

Protecting Critical Underwater Assets

Monitoring What Matters
Beneath the Surface

Underwater infrastructure faces unique challenges, from seabed settlement and structural movement to changing marine conditions. Understanding these changes is essential to maintaining asset integrity and supporting informed engineering decisions.

 

Geonamics designs customised subsea instrumentation and monitoring solutions around each client’s requirements. By combining suitable sensing technologies with project-specific monitoring approaches, we help clients obtain valuable insights into the condition and behaviour of critical underwater assets.

 

Our capabilities also extend to underwater grouting and coring services, supporting marine infrastructure repairs, quality testing and condition assessment.

Subsea Instrumentation

Advanced Monitoring for Underwater Infrastructure

Geonamics develops customised instrumentation and monitoring solutions to help assess the behaviour and condition of subsea infrastructure. Our approach considers the specific characteristics of each asset, site conditions and monitoring objectives to identify suitable technologies for the application.

 

Our capabilities include fibre optic sensing and Shape Accel Array (SAA) technology, alongside other suitable instrumentation solutions.

Seabed Settlement Monitoring
Monitor changes in seabed levels and ground movement to support the assessment of underwater ground conditions and infrastructure stability.
Structural Movement Monitoring
Track structural movement and deformation to provide insights into the behaviour of underwater infrastructure over time.
Asset Integrity Assessment
Gather monitoring data to support the assessment of asset conditions and help identify changes that may require further investigation.
Safety & Security Awareness
Provide monitoring insights that support awareness of changes affecting critical underwater assets and inform appropriate follow-up actions.
Real-Time Monitoring Insights
Deliver timely monitoring information to help clients understand changing conditions and make informed engineering decisions.
Tailored Techology

The Right Instrumentation for Every Project

No two subsea environments are alike. Geonamics takes a customised approach to subsea instrumentation, selecting suitable monitoring technologies based on the infrastructure, site conditions, measurement requirements and each client’s objectives.

Fibre Optic Sensing
Distributed sensing technology used to monitor strain, temperature and other physical changes along instrumented assets.
Shape Accel Array.
An array-based sensing technology used to measure deformation profiles and monitor ground movement.
Security awareness.
Monitoring approaches used to identify potential disturbances and support security awareness around critical underwater infrastructure.
Marine Infrastructure Services

Specialised Underwater Grouting & Coring

Geonamics provides customised underwater grouting and coring services for marine infrastructure repairs, quality testing and condition assessment, tailoring methods to the asset, site accessibility and marine conditions.

Underwater Grouting
Underwater grouting services support marine infrastructure repair and other applications requiring grout placement below the waterline. The method and materials used are determined by the project requirements, asset conditions and site constraints.
Underwater Coring
Underwater coring supports the collection of samples from selected locations for quality testing and condition assessment. The coring approach is planned according to the material, sampling objectives and accessibility of the structure.
Marine Access & Operational Support
Depending on the project requirements, our operations can utilise marine vessels, jack-up barges and diver support to facilitate underwater works.

Each project is assessed individually to determine an appropriate approach based on the infrastructure, working environment and required outcomes.
