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.


Flemish Pass Acoustic Monitoring: Ambient Characterization and Marine Mammal Monitoring near a Mobile Offshore Drilling Unit

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.
