SMRU Consulting

What SMRU Consulting does

SMRU Consulting is a specialist marine mammal consultancy that delivers environmental impact assessments (EIAs), appropriate assessments (AAs), population consequence modelling, and bespoke research to clients developing or operating in the marine environment. The firm serves offshore wind, tidal and wave energy, government, port authorities, defence, and oil and gas clients across the UK, Europe, and North America, with offices in St Andrews (UK), Vancouver (Canada), and Friday Harbor, WA (US). Its core technology stack combines purpose-built real-time passive acoustic monitoring hardware — the CAB Sentinel (single hydrophone) and the three-hydrophone CAB Guardian localisation system — with proprietary statistical frameworks, most notably the iPCoD population consequences of disturbance platform (open-source R package on GitHub) and the ACCURATE acoustic cue rate synthesis. Engagements are typically won through direct B2B sales, regulatory mandates, and collaborative research consortia, with revenue generated via time-and-materials professional services at daily fee rates supplemented by leased CAB hardware deployments and paid support for iPCoD. The firm operates as a trading name of SMRU Limited, part of the SOI Group affiliated with the University of St Andrews' Scottish Oceans Institute, and maintains long-running public infrastructure such as the Lime Kiln live hydrophone on San Juan Island.

Core offering

SMRU Consulting provides specialist marine mammal science consultancy including survey design, Environmental Impact Assessments (EIAs), Appropriate Assessments (AAs), and population-level risk modelling. The firm also develops and sells proprietary passive acoustic monitoring hardware (CAB Sentinel and CAB Guardian buoys) and the open-source iPCoD population consequences of disturbance modelling framework for clients in offshore wind, tidal energy, government, infrastructure, defence, and oil and gas sectors.

Product overview

SMRU Consulting is a marine mammal consultancy offering a portfolio of acoustic monitoring products and scientific consulting services. The core product line includes the CAB (Communications Acoustic Buoy) family: the CAB Guardian with three hydrophones for whale localization and tracking during offshore wind construction, and the CAB Sentinel for lightweight detection monitoring. The company also provides the iPCoD statistical modeling platform for assessing population-level impacts of disturbance on marine mammals. Services include environmental impact assessments, population surveys, and risk frameworks across marine sectors including tidal energy, offshore wind, wave energy, government, infrastructure, defence, and oil and gas. Key research projects include ACCURATE (acoustic cue rates) and PCoD frameworks, with notable infrastructure including the Lime Kiln Live Hydrophone in the Salish Sea.

• CAB Guardian: Real-time passive acoustic monitoring buoy with three hydrophones for detection, classification, location and tracking of marine mammals
• CAB Sentinel

Products and services

• CAB Guardian Three-hydrophone real-time passive acoustic monitoring buoy designed for whale detection, localization, and tracking during offshore wind construction. Enables determination of whale locations within exclusion zones using bearing intersection from multiple units, reducing false alarm rates by 6-12x compared to single-hydrophone systems.
• CAB Sentinel Lightweight battery-powered single-hydrophone acoustic monitoring buoy for detection of marine mammals. Can be handled by single person from small vessel, deployed with moorings or allowed to drift. Used for Southern Resident Killer Whale monitoring and ambient noise studies.
• iPCoD (interim Population Consequences of Disturbance) Statistical modelling framework to assess population-level impacts of noise disturbance on marine mammals. Available in two versions: iPCoD EE (Expert Elicitation) for harbour porpoise, grey seal, harbour seal, bottlenose dolphin, and minke whale; and iPCoD DEB (Dynamic Energy Budget) for harbour porpoise. Open-source R package hosted on GitHub.
• Marine Mammal Consulting Services Specialized consulting services including survey design and implementation, population assessments, risk frameworks, Environmental Impact Assessments (EIAs), and Appropriate Assessments (AAs) for marine sectors including renewables, government, infrastructure, and oil and gas.

Broad incumbents

• RPS Group: RPS Group is a large global environmental and marine consulting firm providing EIA, marine mammal assessment, and consenting support across offshore wind and marine infrastructure. They compete for the same offshore wind developer clients but as a broad multidisciplinary consultancy rather than a marine mammal specialist.
• SLR Consulting: SLR Consulting provides environmental and marine EIA services including marine mammal impact assessment for offshore wind and marine infrastructure. They compete in the same offshore wind consenting market but with a broader environmental and engineering services portfolio.
• ERM (Environmental Resources Management): ERM is a global environmental consultancy with a marine ecology practice supporting offshore wind EIAs, marine mammal assessments, and consenting processes. They serve many of the same offshore wind developer clients as SMRU Consulting but as a broad ESG and environmental services firm.
• Wood Group (Wood Environment & Infrastructure): Wood provides large-scale environmental impact assessment and consenting services for offshore wind and marine infrastructure projects globally. They compete for the same developer clients but operate as a broad engineering and environmental consultancy rather than a marine mammal specialist.

Direct peers

• Ocean Sonics: Ocean Sonics designs and manufactures compact, high-performance underwater acoustic recording systems including hydrophones and PAM platforms used by marine mammal researchers and offshore wind developers — competing with SMRU Consulting's CAB hardware line.
• Marine Ecology Consultants Ltd: MEC is a UK-based marine ecological consultancy providing marine mammal observation, PAM, and EIA services to offshore wind and marine infrastructure clients. They overlap with SMRU Consulting's core service offerings in the UK marine renewables market.
• JASCO Applied Sciences: JASCO is a direct competitor in marine acoustic consulting and underwater noise impact assessment. They provide similar PAM services, hydroacoustic studies, and marine mammal impact modeling for offshore wind, oil & gas, and government clients — and are already an SMRU Consulting collaborator on ECHO Program studies.
• Seiche Measurements: Seiche provides PAM equipment and services for marine mammal monitoring, including acoustic deterrents and noise measurement systems used in offshore wind and construction. They are a direct competitor in the PAM hardware and monitoring service space.
• Ocean Science Consulting Ltd: Ocean Science Consulting is a UK-based marine environmental consultancy providing marine mammal observation, passive acoustic monitoring, and EIA support services for offshore wind, oil & gas, and marine renewables — overlapping directly with SMRU Consulting's service portfolio.

Others

• Hatfield Marine Science Center / Marine Mammal Research Program (academic comparator): Oregon State University's marine mammal research programs provide academic competition for grant funding (NAVFAC, NOAA) and publish overlapping frameworks for marine mammal population assessment. They are not commercial competitors but compete for the same research funding pool that supports SMRU Consulting's framework development.
