Marine Acoustics

Physics-based acoustic modelling improves prediction accuracy, strengthens mitigation design, and increases confidence with regulators which helps offshore projects move forward responsibly while protecting marine ecosystems.

Overview

INSPIRE combines seabed-coupled acoustic modelling, species-specific risk assessment, mitigation optimization, and digital twin visualization to transform complex sound physics into a defensible, decision-ready strategy, improving prediction accuracy, strengthening regulatory confidence, and supporting responsible offshore development.

Modelling Offshore Noise Across the Project Lifecycle

We model all underwater noise from offshore construction, operations, and decommissioning across a wide range of marine infrastructure projects. Sound sources include impact and vibratory pile driving, drilled foundations, dredging, UXO clearance, geophysical surveys, cable and pipeline installation, vessel operations, and fixed or floating offshore structures.

Our frequency-dependent modelling evaluates both acoustic pressure and particle motion, coupling water-column and seabed propagation to capture real-world sound transmission in shallow-water and continental shelf environments. By incorporating geoacoustic parameters, equipment specifications, and installation methods, we produce accurate predictions that support impact assessment, regulatory compliance, mitigation design, and cumulative effects analysis.

Seabed-Coupled Propagation

By realistically modelling how sound travels through both water and seabed sediments, we improve impact prediction where it matters most — during in-water activities near foundations and in shallow shelf environments. The result: more accurate exposure estimates, better-targeted mitigation, stronger regulatory confidence, and more effective protection of marine species.

From Sound Levels to Biological Risk

INSPIRE translates acoustic modelling results into clear, regulator-aligned ecological risk assessments that help developers understand real biological consequences, not just sound levels. By evaluating species vulnerability, exposure severity, cumulative effects, and uncertainty, we provide transparent, repeatable risk characterization that strengthens defensibility, supports proportionate mitigation, and reduces permitting delays.

Digital Twin & Acoustic Visualization

INSPIRE extends traditional acoustic modelling through digital twin integration, advanced visualization, and animation – transforming complex sound field outputs into interactive, decision-ready tools. This enables developers and regulators to explore “what happens if” scenarios and understand acoustic risk before decisions are locked in. We convert model results into virtual reality, dynamic spatial representations that allow developers and regulators to see how sound propagates through the marine environment over space and time depending on the scenario design.

Mitigation Optimization, Not Just Compliance

INSPIRE evaluates mitigation technologies and construction strategies to identify solutions that are effective, proportionate, and practical. By comparing attenuation systems, construction and operation methods, and sequencing scenarios, we help developers reduce biological risk while maintaining construction efficiency, controlling costs, and strengthening regulatory confidence before decisions are locked in.
