Impacts and risks for Community groups
Light emissions
Our proposed activities offshore that may result in light emissions include:
- Vessel operations
Impact
- Change in ambient light
Risks
- Change in fauna behaviour
Controls
To mitigate or reduce the impacts and risks of our activities we will:
- Conduct a pre-campaign risk review for light
- Implement Marine Assurance Process (e.g. comply with Marine Order 30)
- Implement Light Management Measures (e.g. Vessel non-essential light positioning)
Other atmospheric emissions
Our proposed activities offshore that may result in Atmospheric Emissions include:
- Vessel and MODU operations
- Helicopter operations
Impact
- change in air quality
Controls
To mitigate or reduce the impacts and risks of our activities we will:
- Implement a Marine Assurance Process for vessels
Planned discharges
Our proposed activities offshore that may result in planned discharges include:
- Vessel operations
- Installation of subsea structures
- Maintenance and repair
Impact
- change in water quality and change in sediment quality.
Risks
- injury / mortality to marine fauna.
Controls
To mitigate or reduce the impacts and risks of our activities we will:
- Implement a Marine Assurance Process
- Implement an Offshore Chemical Assessment Procedure
- Ensure the vessels meet emissions and discharge standards prior to commencing an offshore activity
- Undertake a campaign risk review
Invasive marine species
Activities
- Ballast water adjustments by MODU and / or support vessels to maintain stability.
- Biofouling by MODU and / or support vessel through IMS presence on submerged surfaces
Risks
- IMS transferred into field, establishes and spreads.
- IMS is transferred between vessels, establishes and spreads to other areas.
- IMS is transferred out of the field and establishes outside the region and spreads.
Controls
- IMS Risk Management Protocol
- Australian Biofouling Management Requirements
Unplanned interactions with marine fauna
Our proposed activities offshore that may result in unplanned interactions with marine fauna include:
- Vessel and MODU operations
Risks
- Injury / mortality to marine fauna.
Controls
To mitigate or reduce the impacts and risks of our activities we will:
- Implement Offshore Operational Procedures (e.g. distances and management practices for interacting with cetaceans)
- Implement Offshore Victoria Whale Disturbance Risk Management Procedure to ensure our activities are not inconsistent with relevant EPBC species recovery plans
Accidental or uncontrolled hydrocarbon release
Our proposed activities offshore that may result in accidental hydrocarbon release include:
- Vessel operations
- MODU (drilling) operations
Impact
- Change in water quality
Risks
- Change in habitat
- Change in fauna behaviour
- Injury / Mortality to Fauna
- Changes to the Functions, Interests, or Activities of Other Users
Controls
To mitigate or reduce the impacts and risks of our activities we will:
- Implement a Marine Assurance Process (e.g. compliance with Marine Orders)
- Implement Marine Exclusion and Caution Zones
- Undertake ongoing engagement
- Maintain an Operational and Scientific Monitoring Program
- Have an accepted Oil Pollution Emergency Plan for the activity
- Have regulatory Safety Management Plans in place
- Operate in accordance with a NOPSEMA accepted Well Operations Management Plan (WOMP) and Safety Case.
Loss of Materials or Waste Overboard
Our proposed activities offshore that may result in Loss of Materials or Waste Overboard include:
- MODU (drilling) operations
- Vessel operations
- ROV operations
Risks
- Change in Habitat
- Injury / Mortality to Marine Fauna
- Change to Cultural Heritage
Controls
To mitigate or reduce the impacts and risks of our activities we will:
- Implement a Marine Assurance Process
- Implement Offshore Operational Procedures
- Ensure Vessels meet Emissions and Discharge standards
