Public Information Booklet
The second major source of CO2 comes from the reservoir. The three hydrocarbon
reserves (Brecknock, Calliance and Torosa) that form the basis for the Browse
development have an average of every one in ten molecules being CO2 (10 mol%). This
results in approximately 15 million tonnes of CO2 per annum for 50 million tonnes of LNG
per annum and approximately 3.3 million tonnes of CO2 per annum for 11 million tonnes
of LNG per annum. Typically this 'reservoir CO2' will be vented to the atmosphere.
Woodside is investigating the option of reinjecting this CO2 back into a safe underground
formation where the gas will be trapped.
The plant will be designed to meet atmospheric emissions and discharge limits which
protect the health and safety of the community and protect the natural environment. This
will be a requirement of obtaining environmental approval and operating licences which
must be in place prior to the commencement of construction.
Safety, Security and Risk Management
Questions:
� What are the consequences of a gas leak in salt water?
� What are the consequences of a gas leak onshore?
A natural gas leak in salt water or onshore will primarily be a safety concern. The plant
will be designated as a major hazard facility and is required to demonstrate that all safety
risks are properly managed to low levels. The industry has mature and rigorous
processes in place to identify and manage these risks to ensure that they are maintained
at levels considered to be as low as reasonably practicable.
Question ñ What kind of safety management system will be in place (e.g.
monitoring)?
The industry is committed to providing a safe workplace for its employees, contractors,
suppliers and its neighbours.
For example, Woodside believe that all incidents, occupational injuries and illnesses are
preventable and are fully committed to achieving our health and safety aspiration of 'no
one gets hurt, no incidents'.
Additionally, Woodside has an Australian Standard compliant health, safety and integrity
management system that is led by a qualified, experienced and competent team.
Compliance with Woodsideís system is monitored through analysis of incidents and
hazards, internal and external audits, feedback from senior personnel and a particularly
important cultural survey involving all employees. In addition to this Woodside employs a
variety of monitoring key performance indicators - some are lagging indicators such as
total recordable incident frequency (TRIF) and others are leading indicators, for example
training programmes and competency programs.
All Woodside operated sites are also required to work under a safety case regime which
has to be approved by regulators. Effective and proven health, safety and integrity
management are the foundations to a safety case regime and require specific,
measurable targets that are monitored throughout the year. A safety case provides the
