Offshore instrumentation and monitoring

Ensuring the integrity and performance of offshore structures requires advanced instrumentation and monitoring solutions. NGI specializes in offshore structural health monitoring, providing cutting-edge technology to optimize design, detect early degradation, and extend the lifespan of offshore installations. Our comprehensive solutions support offshore wind farms, oil and gas platforms, and other marine structures, offering real-time data for informed decision-making.

Expertise in Offshore Monitoring

With a track record dating back to the 1970s, NGI specializes in offshore structural health monitoring, offering both subsea and topside solutions that withstand harsh offshore conditions. Our expertise spans offshore wind farms and all types of offshore installations.

Comprehensive Turn-Key Solutions

NGI, in collaboration with a network of sub-suppliers, delivers complete structural health monitoring systems. Our focus is on providing tailored solutions that generate meaningful data for clients, including guidance on instrumentation specifications. As an independent system provider, we continuously seek innovative sensor components to enhance monitoring performance.

From Concept to Commissioning

Our involvement spans the entire process, from concept development to installation and commissioning. This approach often leads to novel, robust solutions that simplify installation and ensure accurate data representation. We prioritize functionality, integrity, and accuracy, understanding that in offshore instrumentation, every detail matters.

Integrated Monitoring Systems

An integrated monitoring system combines a diverse sensor network to comprehensively assess structural response and health. By linking different parameters and consolidating data acquisition infrastructure, we reduce costs and enhance efficiency compared to independent monitoring setups.

Key Measurement Capabilities:

NGI and its sub-suppliers provide integrated monitoring solutions for various parameters above and below sea level, including:

Soil Conditions: Pore pressure, total stress, and settlement
Structural Response: Dynamic motion, vibrations, strain, stress, leveling, deformations, displacement, and load distribution
Environmental Factors: Wind, wave height, temperature, air quality, water levels, currents, and seabed scour
Material Integrity: Corrosion rate (ER/LPR nodes) and cathodic protection (reference electrodes)

All sensors are connected to a modular data acquisition system, customized for each instrumentation scheme.
