1/3
FEED phaseFollowing successful option identification and
assessmentduring the concept phase, a FEED is an essential part
ofthe project lifecycle. A robust FEED will deliver not just
thefinal concept to be taken forward into construction, but
willalso provide the estimate for final sanction together with
thedocumentation for the next contracting phases. In addition,in
the current climate where schedules are challengingand key
equipment often on long delivery times, the FEEDoutput will enable
procurement activity to commence priorto main contract award.
Petrofacs engineering teams have a broad mix of skillsrequired
to support concept development to FEED levelfor offshore and
onshore developments, from drilling andproduction technology
through facilities design to exportoptions. This skill base is
supported by other Petrofaccapabilities in fabrication and
operations. These enabledesign solutions to be developed that
address buildabilityand operability issues at the earliest stage of
engineeringdevelopment.
Offshore FEED
Engineering approachPetrofac is able to offer development
experience froma wide range of geographic areas, from the North
Seaand offshore Malaysia to the calmer waters of
theMediterranean.
We have extensive experience in executing projectsfor offshore
oil & gas production facilities including thedevelopment of
both greenfield and brownfield assets thatcover the following:
minimum facility fixed platforms floating production, storage
and offloading (FPSO) integrated drilling, processing and export
platforms mobile drilling and production units subsea production
facilities
Our core facilities design expertise is supplemented
withspecialist offshore capability that includes:
installationdesign (transportation and lifting), mooring analysis,
riserdesign, offshore piling design, vessel motion analysis andflow
assurance.
Onshore FEEDOur onshore FEEDs are supported from our in-house
multi-discipline engineering resources including process
engineering (including flow assurance and
dynamic simulation) instrument engineering (control systems,
field
Instruments and metering) electrical engineering metallurgy and
materials engineering piping layout design piping engineering
(including piping stress analysis and
materials) civil engineering structural engineering risk, safety
and environmental engineering pipeline engineering
Petrofac has extensive experience in the design of onshoreand
offshore facilities for both oil & gas treatment facilitiesand,
therefore, is able to produce designs that are fullyintegrated with
any downstream facilities.
Our FEED level work is supported by a cost estimatingfunction
that reflects the very latest cost information throughour worldwide
procurement capability. Our structured andtransparent approach has
been used for a variety of majoroperating companies, and can be
customised to supportindividual client stage gate decision
processes in terms ofestimate accuracy and interpretation of risked
estimates.
At both concept and FEED levels, our design teams providerobust
and practical solutions which incorporate Petrofacsextensive EPC
and operations experience both onshoreand offshore. This experience
has been gained throughexecuting projects in some of the most
environmentallyand climatic-challenging regions of the world. Using
thisapproach ensures that the correct level of experience
ismobilised at the earliest opportunity within a project whereits
influence can add the most value.

Onshore design experiencePetrofac has been involved in a variety
of projects at FEEDlevel include the following:
Turkmenistan:FEED for sales gas project.Scope covered the design
of 20bcma of sales gasproduced from 40 operating wells and a 56
inch exportpipeline, process technology and sensitivity studies,
andtechnical reviews of process licensor packages.
Uganda:FEED service for oil plant and export pipelineProduction
gathering, main process plant with capacity for40,00bopd and 80km
heated pipeline.
Kazakhstan:FEED project for gas plant projectFEED to manage the
increasing Gas Oil Ratio (GOR) of thereservoir fluid with time and
capturing the value in the gasreserves. Project focused on delivery
of 16bcma of gas toexisting customer in Russia, which entailed an
increase ofapproximately 8bcma over previous gas export
quantities.
Russia:FEED project for gas plant projectProject included the
additional of two new remotely located
well sites with production and water injection capabilities.New
oil & gas treatment systems were also added tothe central
processing facility to ensure that the exportoil and export gas
specification are met. The CPF afterphase III modification handled
a capacity of 30,000bopd,700,000Sm3 of gas and 60,000bwpd of
injection water.
Nigeria:FEED for provision of LPG extraction plantFEED included
cost estimate, preparation of SOW and ITTfor EPC bidders. Scope
included an LPG extraction plant,with the capacity to process
400MMscfd gas, downstreamof the existing flow station to service
two fields to recoverpropane, butane and heavier hydrocarbons from
theassociated gas to produce a saleable liquid product.
Algeria:FEED design competitionFEED for oil and gas gathering
system and centralprocessing facilities to tie in to existing
facilities. Peak oilproduction of 30,000bopd with 100MMscfd
gas.
Iran:FEED and early production worksFEED for 8 wells producing a
total of 20,000bopd. Scopeinvolved process design including flow
assurance, piping,civil and structural, HSE studies, project
schedule and costestimation.
Offshore design experiencePetrofac has been involved in a
variety of projects at FEEDlevel that include the following:
Tunisia:FEED for normally unmanned facilitiesConcept
development, followed by FEED, for normallyunattended facilities in
62m water depth offshore Tunisiadelivering 150MMscfd gas to a new
onshore processingand treatment plant. Scope included a 110km
18multiphase subsea pipeline and FEED of the onshorefacilities.
UK North Sea:FEED for Southern North SeaFEED for 6 slot minimum
facilities normally unattendedplatform in 20m water depth. The
scope includes a 450ttopsides and 425t conventional jacket
structure togetherwith a 45km 10 export pipeline supporting
120MMscfd gasproduction. The final concept included use of an
innovativesubsea cooler.
UK North Sea:FEED and EPC for tie-back facilitiesAdditional
module for single well tie-back to support15MMscfd production
together with compression facilities
and 10km subsea pipeline. Concept based on stand alonehang off
module installed on an existing platform andwas specifically
designed to maximise onshore completionand commissioning thus
minimising expensive offshoreconstruction work.
Nigeria:FEED and detail designFEED and detail design for shallow
water fixed platformsfor near shore facilities for production of
60,000bopd. Thefacilities included separation, utilities and power
generationand were bridge linked to existing facilities.
Petrofacsubsequently undertook the detail design of the
facilities.
UK North Sea:Fast track marginal field developmentFast track
marginal field development in approximately150m water depth. Final
development solution comprisedsubsea tie-backs to an existing
floating production facility(FPF) with shuttle tanker export.
Petrofac scope includedfull FEED including upgrades to the existing
processingfacilities together with long lead procurement
support.
