|LNG Capability andExperience|
|Greenfield LNG |
Worley’experience in greenfield LNG developments extends from opportunityevaluation, concept/technology selection, FEED and EPCM, tocommissioning, start up and operations support. Along with our jointventure partners we have pioneered
the development of the world’sfirst moduralized LNG plants including the North West Shelf Phase VDevelopment and the Pluto LNG project.
Expansionof existing LNG facilities is becoming more prevalent as LNG demandincreases. Worley has extensive experience in plant optimizationand brownfield LNG projects including the coordination of expansionprojects with existing operations. Our work has covered Australia,Asia, and the Middle East.
|Offshore LNG |
Offshore projects require many designconsiderations to be integrated into the
development process, making strong offshore experience a vital successfactor.
Worley’ offshore heritage, coupled with our LNG experience, putsus at the
forefront of developments in offshore LNG. This is exemplified by ourkey role in the
conceptual engineering phase of what is planned to be the world’slargest offshore
Worleyhas the expertise to deliver both small and large LNGterminal/regasification developments and has particular strengths inthe application of novel concepts and innovative designs. Ourexperience in floating production and off loading systems, combinedwith expertise in pipelines, storage, loading and regasification, makesWorley a contractor of choice to perform terminal
designs and construction management.
|Mid and Small Scale LNG |
Midand small LNG plants are becoming increasingly prevalent in theindustry and are particularly important for monetizing stranded gas,debottlenecking existing facilities and providing the growing transportfuel market. Worley has a variety of experience in these smallerscale LNG projects including both mid (<2 MTPA) and small(<0.2MTPA) facilities.
|LNG Modularization |
Worleyis a recognized global leader in the modularization of process plants,with experience spanning from the North Slope of Alaska to the Caspianregion and the remote North West Shelf of Australia. In conjunctionwith our joint venture partners, we have used this experience topioneer modularization in LNG plants. LNG modularization has beenproven to reduce costs, schedule, industrial relations risks andenvironmental impacts and is particularly applicable to remote regionsand those with high local labor costs.
LNGdevelopments can have considerable infrastructure requirements whichoften comprise a significant portion of the total capital cost and areusually a schedule constraint and a key environmental risk of aproject. Worley has a large infrastructure group
with a trackrecord in delivering outstanding integrated solutions to onshore andoffshore LNG facilities. We can address all the infrastructure needs ofa LNG project including geosciences, ports and jetties, dredging,coastal analysis and civil engineering.
Environmentaldecisions made during all phases of a project are a major determinantof the ultimate business outcome of the project. Worley’ globalteam of over 500 professionals in environmental sciences assistscustomers throughout the project life cycle, from data acquisition,decision making and design through to project implementation,operations and decommissioning.
|Local Presence |
Worleyhas over 32,200 people in offices across 38 countries and this enablesus to provide our customers with local presence, local knowledge and
localunderstanding in virtually all parts of the world where LNGdevelopments are contemplated. Our commitment to local presence enablesus to bring this local knowledge and relationships to our customers’projects often making Worley the partner of choice for LNGprojects.

|Project:Pluto LNG Development |
Customer: Woodside Energy Ltd
|Woodside is developing its Plutooffshore gas field through an offshore production |
system and an onshore LNG production plant with an initial capacity offive to six
million tonnes per year. Worley has key roles in the FEED andEPCM joint
ventures executing the offshore platform, onshore plant facilities andassociated
site infrastructure and marine facilities. The development scopeincludes a series
of deepwater subsea wells, tied back by flowlines to a remotelyoperated platform
which will export the gas to an LNG plant via a subsea trunkline. Theonshore
LNG facilities include slug-catchers, gas pre-treatment, liquefaction,fractionation
and storage facilities together with utilities and LNG loading jetty.
|Project:Papua New Guinea LNG Project |
InterOilidentified a project development concept for the commercialization ofgas resources within PNG through an LNG export facility. WorleySelect was engaged to determine the technical feasibility of theproject, quantify the cost and schedule for the project execution, andprovide input for the project economics. Worley brought a uniqueblend of LNG, PNG, pipeline and infrastructure experience to theproject to address the entire project scope, including elements such ascompression stations; onshore, nearshore and offshore pipelines;reception
facilities; LNG facilities and technology selection; LPGfacilities infrastructure; and jetty and loading equipment.Worley’ Select also addressed contracting strategies, majorexecution risks, construction methodology and project schedule.
|Papua New Guinea|
|Project:Design Engineering Managing Contract |
Customer: Brunei LNG
|Worleyconducted extensive services for a series of modifications to theBrunei LNG plants to extend the life of the facilities for a further 30years. The work undertaken included the preparation of screeningstudies, feasibility studies, basis of design, basic design andengineering packages, detailed design and EPC contract documents.Worley also managed consultants and supplied specialistpersonnel on secondments to Brunei LNG, and is currently providing theIntegrity and Business Improvement services for the operating asset.|
|Project:Extended Liquefaction Study |
Customer: Woodside Energy Limited
|WorleySelect conducted a study to determine the feasibility of operating anexisting base load LNG facility in extended end flash mode andreliquefying the increased boil-off gas (BOG), essentially increasingthe LNG capacity of the plant by 1 MPTA. The study confirmed thatinstallation of additional BOG compression would increase LNGproduction and that BOG could be liquefied without further treatmentand returned directly to the LNG tanks for loading. The re-liquefactionfacility design was based on a single mixed refrigerant process, themost appropriate for 1 MTPA plants. The study also optimized theoverall configuration within the constraints of the existing plant anddeveloped layouts and cost estimates to support both the |
greenfield portion and the significant brownfield modificationsrequired.

|Project:North West Shelf LNG Phase V Expansion Project |
Customer: Woodside Energy Ltd
|TheUS$2B LNG expansion of the Karratha Onshore Gas Plant pioneeredmodularization for LNG plants. It was the first large scaleliquefaction plant in the world to be designed and built inpre-assemblied modules and racks. The key components of the facilityconsisted of more than 70 modules constructed in Batam, Indonesia andshipped to the Australian coastal site on some of the world’s largestheavy transport ships. The tallest and heaviest pre-assembly was 36mhigh and weighed 2,000 tonnes. Worley, as part of a jointventure, is providing EPCM |
services. The scope includes the design,construction and commissioning of a fifth liquefaction train, togetherwith an additional fractionating unit, acid gas recovery unit, boil-offgas compressor, two new gas turbine power generation units, a secondloading berth, a new fuel-gas system compressor and otherrelatedfacilities.
|Project:The NWSV LPG and LNG Jetties |
Customer: Woodside Energy Limited
|TheNorth West Shelf Venture’s LPG and LNG berths are located adjacent toNWS LNG production plant and are utilized for the export of LPG and LNGcargos. Safety of the cargo and vessels is a primary requirement, whichis heavily dependent upon vessel conditions at the berth and in thechannels. Worley performed a detailed numerical vessel motionand mooring analysis study for these facilities using in-house computermodeling capabilities. The limiting conditions for mooring lines wereassessed to determine the maximum allowable cyclonic swell conditionsat the berth. Under keel clearances along the shipping channel werealso analyzed and |
the results formed the basis of port operating procedures.
