Oil & Gas, Geoscience
Comprehensive acoustic services
JASCO Applied Sciences provides scientific consulting services for all stages of environmental reviews and assessments related to underwater and in-air acoustics.
Our services benefit:
Oil and gas companies of all sizes
Geophysical survey providers
Environmental consulting firms
Logistics providers
Assessment of all sources of noise
Our services encompass all types of industrial noise sources related to oil and gas exploration, production, and geoscience, including:
Port and terminal construction and expansion, and subsequent vessel traffic
Seismic and geophysical surveys
Drill ships and platforms
Support vessels of all types
Construction, nearshore and offshore
Effective project management
In large projects with numerous subcontractors and/or joint sponsors, logistics are complex and the technical regulations for preventing underwater acoustic impacts can be especially challenging to implement.
Our experienced project managers and field scientists liaise with project sponsors, contractors, and regulators to ensure that our scope of work is targeted and meets all objectives. We help stakeholders find common ground between environmental conservation and operational feasibility, so operations can succeed with minimal environmental impact and in full compliance with regulations.
We help our clients determine:
What the regulations are
How the regulations apply to their project and operations
What measures are needed (predictive sound modelling, measurements, mitigation, etc.)
How those measures can be implemented effectively and efficiently
Adaptable operations
Our equipment is readily tailored to our clients’ constraints and resources. We deploy equipment from work vessels of all sizes. Our extensive range of measurement capabilities offers versatile solutions to satisfy our clients’ requirements:
Autonomous underwater recorders for short and long deployments
Acoustic telemetry buoys for real-time monitoring
Towed arrays for passive acoustic monitoring of marine life
Cabled hydrophones for nearshore measurements
Over-the-side hydrophones deployed from vessels for rapid measurements and characterizations

Viva Energy Gas Terminal Project EES Technical Report A2
March 2022 — Southeast Australia
Client: AECOM
Appendix A-1 – Baseline Monitoring of Ambient Underwater Noise Environment
Appendix A-2 – Underwater Noise Modelling
Appendix A-3 – Underwater Noise Impact Assessment
Three underwater noise studies that form part of the Environment Effects Statement for the Viva Energy Gas Terminal Project in southeastern Australia. The project will develop a gas terminal using a floating storage and regasification unit (FSRU) moored at Refinery Pier in Corio Bay, Geelong to facilitate supply of a new source of gas for the south-east Australian gas market where there is a projected supply shortfall in coming years.
December 2021 — Newfoundland, Canada
Client: Wood Environment and Infrastructure Solutions
An acoustic monitoring study to measure the acoustic signature of the Mobile Offshore Drilling Unit (MODU) Stena Forth, a dynamically-positioned ultradeep-water drillship, at the Pelles A-71 exploration well. The results are compared to modelled predictions. Baseline sound levels were measured as well as marine mammal presence and changes to the baseline resulting from the Pelles drilling program.
Geographe Subsea Installation & Commissioning: Acoustic Monitoring and Updated Modelling
June 2021 — Southern Australia
Client: Beach Energy Ltd
Appendix 7 – Sound Transmission Loss Modelling Report (Updated)
Appendix 8 – Beach Otway Development Acoustic Monitoring
Underwater sound monitoring and acoustic characterisation of drilling activities by the Ocean Onyx Mobile Offshore Drilling Unit (MODU) and of associated support vessels at the offshore natural gas fields of the Otway Basin. Four AMARs in C-Lander moorings were deployed at increasing distances from the MODU. The results were compared against the previously modelled sound field predictions from the draft Environment Plan. The findings provided a better understanding of the propagation loss environment, enabling a recalculation/update of the modelled scenarios to provide more accurate distances to acoustic thresholds for impacts to marine mammals.
