Executive Summary
IntroductionThe Sunrise Gas Project Joint Venture, operated by Woodside Energy Ltd (Woodside), proposes todevelop the Greater Sunrise gas and condensate field which is located in the Timor Sea approximately450 km north-west of Darwin and 150 km South of East Timor. Investigations indicate that theGreater Sunrise Gas Field has a ‘Scope for Recovery’ in the order of 9 trillion cubic feet of gas and300 million barrels of condensate. Figure ES1 shows the location of the Sunrise Gas Field andsurrounding gas fields.
The Sunrise Gas Project is a joint venture between Woodside (Operator), Phillips STL Pty Ltd, ShellDevelopment (Australia) Pty Ltd and Osaka Gas Australia Pty Ltd. Woodside Energy Ltd is a leadingoil and gas company and one of Australia’s most successful explorers, developers, and producers ofhydrocarbon products. As a participant in, and Operator of, the North West Shelf Joint Venture,Woodside is directly responsible for the management of offshore and onshore assets worth more than$9 billion. On Western Australia’s North-West Shelf, Woodside operates the North Rankin A andGoodwyn A offshore production platforms, the Cossack Pioneer Floating Production Storage andOfftake (FPSO) facility and the Onshore Gas Plant (OGP) on the Burrup Peninsula.
For the Sunrise Project this document addresses the environmental issues associated with the proposedoffshore facilities, potential pipelines and related plant that have the potential to cause biophysical orsocial effects, or which are known to be of public interest. The document has been prepared toprovide the Northern Territory Government, agencies of the Commonwealth of Australia and thepublic with the information necessary to enable an informed appraisal of the environmentalacceptability of the proposed project.
Contact DetailsThe designated operator of the Sunrise Gas Project is:
Woodside Energy Ltd1 Adelaide TerracePerth WA 6000
Legislative Framework and Regulatory Authorities and AgenciesAs the Sunrise Gas Project requires assessment under both the Northern Territory and theCommonwealth environmental assessment legislation, the two government bodies have agreed tofacilitate a joint assessment. As such both the Minister for the Environment (Commonwealth) and theMinister for the Environment (Northern Territory) have set the level of assessment for the project asan Environmental Impact Statement (EIS). Furthermore both governments have agreed that theEnvironment and Heritage Division of the Northern Territory Department of Infrastructure, Planningand Environment (DIPE) will take the lead role in the assessment process. The final guidelines issuedfor the project reflect the recommendations of both governments. The final documentation will beassessed by each jurisdiction, with each government making its own decision.
Approximately twenty percent of the Greater Sunrise reserves lie within the Zone of Cooperation,which was initially established in 1991 under treaty between the Australian and Indonesiangovernments to jointly exploit petroleum resources in adjacent territorial waters and which will becontinue with the newly elected government in East Timor by means of the Timor Sea Arrangement

(TSA). However, the production facilities will be located largely within Australian waters and theNorthern Territory and Commonwealth governments will comment on the EIS within the processoutlined above.
All activities associated with the proposal will comply with the legislative requirements establishedunder a combined Territory and Commonwealth Government framework under which the Project willreceive environmental, planning and development approvals and authorisations.
Project JustificationUndeveloped reserves of gas contribute nothing to economic development and community livingstandards. For the economies and citizens of East Timor, the Northern Territory and the rest ofAustralia to benefit from the Greater Sunrise gas reserves in the Timor Sea, the fields must bedeveloped and commercial sales made to customers.
Development and production of the gas and condensate will benefit the various economies through:� The front end engineering and detailed design phases, where Australian and international
expertise will apply the latest design concepts and technologies to design world class facilities;� The construction phase when capital investments to produce, transport and process the gas are
made; and� The operations phase when gas is produced and used by customers.
The design phases will provide opportunities for skill and knowledge transfer essential to maintainingregional capability in the oil and gas sector. The construction phase will involve large expendituresconcentrated over a short period on the purchase and installation of capital equipment and constructioncosts. Local construction and service industries will have the opportunity to support the installation oflarge capital items leading to a boost in short term jobs in the construction industries and in industriessupplying inputs to construction.
Once the project enters its operations phase permanent jobs will be created in running the productionfacilities. The export of condensate and downstream products will generate income through foreignexchange. This will add to national income and the consumption prospects of the Australian and EastTimorese communities.
The extraction of natural gas will add to the Commonwealth government’s revenue directly throughthe Petroleum Resource Rent Tax levied on gas and condensate production and to the East TimorGovernment’s revenue through the Production Sharing Contract provisions of the TSA. It will alsoadd indirectly to both Northern Territory, East Timor and Commonwealth governments’ revenue byexpanding economic activity, employment, income, expenditure and hence the tax base in theNorthern Territory, the rest of Australia and East Timor. This in turn will enhance the capacities ofboth governments to support desirable social expenditures, including infrastructure development.
The development of the Greater Sunrise gas and condensate fields will secure a long-term source oftax revenue for East Timor. Furthermore, there is the potential for East Timorese involvement inlogistics and support operations to the offshore facilities. Direct employment opportunities on thefacilities will also emerge for those who acquire the necessary skills through appropriate training.
Natural gas is a fuel which produces approximately half the greenhouse gas emissions of other fossilfuel alternatives on a lifecycle basis. In this respect, the development of natural gas supply fordomestic and international markets provides tremendous opportunities for continued economicdevelopment in Australia and East Timor. To the extent that gas can be utilised in place of alternativefossil fuels, global emissions will be reduced in line with Australia’s National Greenhouse Strategy.

Project DescriptionThe Project scope includes the following major components:� Construction and operation of offshore production wells production and processing facilities, and
subsea infrastructure; and� Construction and operation of a hydrocarbon pipeline from the Sunrise facilities to the Phillips
Bayu-Undan gas export trunkline.
The Sunrise Field development will consist of either a combination of platform and subsea wells orentirely of subsea wells. Subsea wells will be linked to the production facility by intra-field pipelinesand export/import risers.
Two main wellstream processing options are under consideration:� Processing by way of processing, compression, utilities and quarters (PCUQ) facilities – the gas
would be exported to Darwin via the main export pipeline to the proposed Darwin LiquefiedNatural Gas (LNG) terminal or other potential customers (Figure ES2a); and
� Wellstream exported directly to an offshore Floating LNG (FLNG) facility via a series offlowlines and risers – the LNG and condensate would be exported from the FLNG facility toavailable markets (Figure ES2b).
The basis of the PCUQ option is a Production Jack-Up facility bridge-linked to the Wellhead Platform(WHP), both platforms being located in a water depth of 140–400 m.
This option provides for full offshore condensate separation, stabilisation and export, requiring theaddition of an Floating Storage Offloading (FSO) facility located approximately 2 km from the PCUQplatform. Condensate production will be transferred to the FSO via an 8 inch subsea flowline.Trading tankers will receive condensate from the FSO on a regular basis, and the gas will be exportedvia pipeline to Darwin.
Figure ES3 shows that the offshore production facilities are designed to deliver two products; naturalgas and condensate. There will be two process trains each having a capacity of 50%. The wellproduction from the wellhead platform and the subsea wells will be manifolded on the wellheadplatform and routed across the bridge to the PCUQ platform. All risers, subsea flowlines and exportstabilised condensate to FSO vessel will be located on the wellhead platform. The facility willproduce export gas routed to a gas pipeline, condensate product routed to FSO and produced water.
Under an OLNG scenario both the Sunrise and Bayu-Undan developments will share a section ofexport gas pipeline comprising approximately 319 km of export pipeline from a Wye piece toWickham Point for use by potential gas customers. This shared section of pipeline has already beenapproved under a separate approval process.
Production from the Greater Sunrise field will commence when suitable gas markets have beenestablished and approved by the appropriate regulatory bodies. This may be as early as mid 2006;however, this date is dependent on the establishment of suitable markets.
While it is recognised that the full field life may range from 30 to 75 years, no specific designallowance is made for extended facilities life beyond a nominal 30 years. Instead, the facilities wouldbe managed and maintained to achieve the life required.
The FLNG option provides for full processing of the wellstream on a large moored barge, includingthe provisions of utilities, support systems and quarters for both the FLNG and Sunrise Upstream

facilities, and for storage and export of both LNG and condensate. Both the Onshore LNG (OLNG)and FLNG plants fall outside the scope of approvals currently sought for the development of theGreater Sunrise gas fields and the installation of associated pipelines. FLNG and OLNG will berequired to follow separate environmental approval processes.
Alternative OptionsA broad range of alternatives have been considered by Woodside including:� The “no-development” option;� The location of the development sites and pipeline routes,� Drilling and platform facilities; and� Process technologies.
The failure to develop the Sunrise Gas Field may have adverse economic implications for Australiawhere the petroleum exploration and production industry is important to the national economy as asource of energy, employment and income. Similarly, no development would deny East Timor anopportunity to finance the rebuilding of one of the world’s newest and poorest nations. The variouseconomic benefits to both nations are outlined above.
The Sunrise Gas Project was initially a stand-alone project and therefore the early pipeline routesconsidered were based on a more direct route from Sunrise to landfall at Shoal Bay on the GunnPeninsula, north-east of Darwin. However, following the agreement to co-operatively develop TimorSea gas with Phillips (operator of the Bayu-Undan field), a number of pipeline routes were examinedthat extended from the Sunrise Gas Field to a ‘Wye’ junction with a pipeline from Bayu-Undan toWickham Point in Darwin Harbour. The pipeline from the Wye junction to Wickham Point (Darwin)is consistent with the route already approved for Bayu Undan.
Various platform drilling rig options have been investigated to minimise the impact of platformfacilities, while optimising the platform drilling capability and minimising capital investment indrilling equipment. Similarly, an assessment of three main production concepts was conducted byWoodside. The choice of the preferred offshore platform was based on geotechnical, environmentaland technical criteria.
The Sunrise Gas Project can demonstrate that the best available technologies for reduction ofenvironmental impact of discharges and emissions have been given due consideration. In this regardWoodside produced the report entitled ‘Environmental Design Review’ in May 2001. Severalavailable technologies have been considered and benefit-cost analysis performed beforerecommendations were made. Specific greenhouse gas reduction measures to be considered as part ofthe Sunrise Gas Project are:� The development and implementation of a greenhouse strategy to minimise emissions of
greenhouse gases;� Design and operational measures to minimise offshore flaring and venting;� The reduction of methane emissions to negligible levels through the combustion of regeneration
offgas;� Maximising the use of waste heat from gas turbines; and� To adopt industry best practice in greenhouse efficient technology and practice wherever
practicable.

Existing EnvironmentPhysical EnvironmentThe climate of the Timor Sea comprises two distinct seasons, a dry “winter” from April to Septemberand a wet “summer” from October to March, separated by transition seasons of short duration.
The mean annual rainfall for the Sunrise Gas Field is expected to be in the order of 1,700 mm with thevast majority of the rainfall occurring between November and March. The mean summer and winterair temperatures are likely to approximately 28oC and 27oC, respectively.
Although tropical cyclones form in the area generally south of the equator in the eastern Indian Oceanand the Timor and Arafura Seas, most storms affecting the Sunrise area are tropical lows ordeveloping storms passing well to the south of the Sunrise Gas Field.
The seabed in the vicinity of the Sunrise Gas Field lies at 140 m to more than 700 m below the watersurface. The south eastern rim of the gas field lies at the top of the steep shelf break where the depthdrops to about 300 m over a distance of 15 km. There are four shallow features adjacent to thesouthern portion of the Greater Sunrise Gas Field, including the Sunrise Banks. These shoals arecovered by minimum water depths of approximately 30 to 40 m.
The preferred subsea pipeline alignment passes through water depths ranging from approximately 140m to 57 m LAT. The route is aligned to avoid shoals and valleys as much as possible.
The development area is situated on the outer shelf and upper slope of the Sahul Platform off thenorthern margin of Australia in the Timor Sea. The surficial sediments along the pipeline route varyin thickness between 0.5 and 2.5 m and range from carbonate silty to carbonate clayey sand withgravel.
The Timor Trench lies between the Sunrise Gas Field and the island of Timor. Subductionearthquakes associated with the Timor Trench dominate the earthquakes of the Sunrise Gas Projectarea. However, the design criteria of the offshore facilities provides for seismic events such asearthquakes, which are of low frequency and an intensity not likely to result in damage.
The sea wave climate at Sunrise Gas Field is closely allied to the prevailing wind regimes, withwesterly and south-westerly seas prevailing from December to March, shifting predominantly easterlyseas from April to November. Predominant swell direction at Sunrise Gas Field is from south-west towest. In summer the one year return period significant wave height is 2.4 and in winter it is 2.8 m.
Tides in the area are semidiurnal, and are expected to flow east-north-east and ebb west-south –west inthe upper 100 m of the water column, whilst flooding south-east and ebbing west-north-west in thelower portion of the water column. Maximum tidal range is about 4 m.
Surface current for the Sunrise Gas field are strongly influenced by the semidiurnal tide and to a lesserextent by the wind-driven and drift currents.
Mean monthly surface water temperatures in the vicinity of the Sunrise Gas Field are expected to varybetween about 26oC and 30oC.
Biological EnvironmentSurveys were conducted at three banks and a deep-water location in the vicinity of the Greater SunriseGas Field. The survey found that each of the three banks support extensive areas of benthic

communities considered as being both diverse and abundant. The proposed platform location (ie deepwater) is generally characterised by a relatively level substrate composed of sand and shell fragments.The area supports sparse epifauna comprised of hydroids, seapens, sea whips and solitary hard corals.
Social EnvironmentDarwin is the capital city of the Northern Territory and its proximity to major economic growth areasin the Asia Pacific region provides a stable foundation for the Territory to play a major role in thefuture of the Asia Pacific Region.
Darwin is serviced with a seaport comprising land connections to a major international airport,national highway system, the proposed national rail network and the proposed Bayu-Undan to Darwinnatural gas pipeline. Darwin is also equipped with world standard communications systems and hasemerging information technology capabilities.
East Timor’s proximity to the gas fields is expected to provide opportunity for its local economy. As alandfall, East Timor is 300 km closer to the development area than Darwin. While infrastructure andcapability constraints currently prevail, East Timor’s capabilities in the area of marine and air supportare likely to emerge within the operating life of the project.
Environmental Effects and Management StrategiesA summary of the environmental impacts related to the development of the Greater Sunrise gas andcondensate fields is provided in Table ES1, which lists:� Project component;� The source of the impact;� The potential or actual environmental impact;� The predicted effect of the impact (negligible, minor, moderate, significant or serious); and� The duration of the impact (temporary, short-term, medium-term, long-term or permanent).
In summary, the identified potential and actual environmental impacts associated with the Sunrise GasProject are:
Atmospheric emissions� Emission of smoke and particulate from production platform operations, and cargo tank emissions
from loading of FSO and shuttle tankers;
Discharges to the Sea� Smothering effects of accumulated drilling cuttings on marine biota;� Potential anoxia of sediment due to natural degradation and/or burial by drilling muds;� Localised reduction in water quality adjacent to off-shore facilities during the construction phase;� The potential discharge to the marine environment of hydrocarbons resulting from a condensate
or diesel spill, or the release of off-specification production formation water resulting in adverseimpacts on the receiving waters;
� Potential localised elevation of water temperature affecting marine organisms;� Contamination of marine environment by anti-fouling agents; and� Potential temporary localised reduction in water quality due to release of hydrotest water
containing biocides, scale and corrosion inhibitors and oxygen scavengers.
Noise, Vibration, Light and Heat� Potential disturbance to marine species due to noise and vibration created by vessels undertaking
project related activities; and

FINAL PAGE vii
Waste to Shore� The improper disposal of waste material generated during the drilling, construction and operation
phases of the project;
Other Impacts� Temporary disruption of fisheries during construction and reduced access to fishing grounds due
to the establishment of an exclusion zone around the offshore production facilities; and along thepipeline; and
� Disturbance to benthic communities that have established on and adjacent to the facility;� Disturbance to seabed and potential changes to seabed characteristics from permanent facilities.
The result from the impact identification can be summarised as follows:� Drilling and Associated Activities: Most of the environmental effects are negligible and of short-
term or temporary duration.� Installation/Construction: Most of the environmental effects are negligible and of short-term or
temporary duration.� Commissioning/Operation: Most of the environmental effects are either negligible, minor or
moderate and of short-term duration. A few significant environmental effects have beenidentified, relating to the potential emission/spill of natural gas and condensate, the duration ofthis effect deemed long-term.
� Decommissioning: Most of the environmental effects were deemed negligible and of short-termduration.
Mitigation measures and management strategies have been recommended for implementation, basedon the APPEA’s ‘Code of Environmental Practice’, and following consultation with all relevantgovernment and non-government organisations, as well as the public. A summary of mitigationmeasures to be implemented at various stages of the projects are included in Table ES2a-b.
The management strategies proposed will ensure that all impacts on the environment will beminimised during the drilling, commissioning, operation and decommissioning phases of the proposal.An Environmental Management System will be developed and implemented by the Proponent. Themajority of the environmental management strategies for the Sunrise Gas Project will be implementedwith the following Environment Plans:
� Drilling Environment Plan: This plan would cover all aspects of drilling of the WellheadPlatform and subsea production wells and the construction and installation of the WellheadPlatform.
� Facility Environment Plan: This plan would cover all aspects of construction/installation,operation and decommissioning of the Sunrise Gas Project. The Facility EP would containspecific plans for decommissioning, waste management, and ballast water management.
In addition to the Environment Plans, project specific plans would also be implemented. Theseinclude:� Oil Spill Contingency Plan.� Emergency Response Plan.� Waste Management Plan
ConclusionsThe majority of the identified potential and actual environmental impacts associated with the SunriseGas Project are assessed as being negligible or minor in nature with temporary or short term effects.As such, this document demonstrates that the project is not expected to pose a significant

environmental threat to the East Timor Sea. Woodside is, in any case, committed to achieving a levelof environmental management and performance that is consistent with national and internationalstandards and statutory obligations during its pursuit of sound business and financial objectives. Tominimise any potential threat to the environment, the most economically effective, environmentallysound technology and procedures will be incorporated into the design of this project. The adoption ofsuch a strategy will ensure optimal management of all emissions, discharges and waste. Furthermore,Woodside is committed to ensuring that the development of the Sunrise Gas Project will beundertaken in a manner that minimises impacts on the surrounding biophysical and socialenvironments.
