Info

Generators will be sized to meet the electrical loads of the FPSO vessel, both for normal and emergencyoperation. They will be able to function on produced gas or diesel. As well, there will be provision forfurther diesel-driven power generation for emergency.The subsea facilities for White Rose will include all equipment necessary for the safe and efficientoperation and control of the subsea wells and transportation of production and injection fluids betweenthe wells and the FPSO. The subsea facilities include all wellhead completion equipment, trees,manifolds, flowlines, umbilicals, risers, seabed structures, control systems and all interfaces required tocontrol and operate the facilities and associated test, installation, inspection and maintenance equipment.Wellhead equipment, trees and manifolding structures will be located in open glory holes for icebergprotection.4.4.2 Export SystemThe offloading facilities will be located at the stern of the FPSO and incorporate a fiscal meteringsystem as an integrated package. The offloading system and offloading rate will be designed with regardto the environmental conditions in the field, such that the availability of the facility is not compromisedby weather limitations on a shuttle tanker connecting or remaining connected.Shuttle tankers will be used for exporting White Rose crude oil to markets in, for example, eastern NorthAmerica and the United States Gulf Coast, or to a transshipment facility, such as the one currently operatingat Whiffen Head, Newfoundland.4.5 Construction and InstallationInitial design engineering is forecast to start several months prior to project sanction in order to meet theearly target date for First Oil and enhance project viability. Any procurement decisions that must be madeprior to receiving regulatory approvals would be subject to the successful outcome of the DA reviewprocess and project sanction. Project sanction by the proponents, which is conditional upon receivingregulatory approval and confirming commercial viability, would initiate the project and lead intoconstruction, installation and commissioning. The target date for First Oil is approximately 36 monthsfollowing project sanction.White Rose DA Project Summary • January 2001 Page 58
4.5.1 Facility ConstructionHistorically, the hull or super structure and topsides of FPSO vessels have been built in separate facilities indifferent locations. This is also expected to be the case for White Rose. Currently, there is no Canadianshipyard large enough to construct the hull. A modular approach will be followed for fabrication of thetopsides. The size of individual modules depends on the lifting capacity available at the shipyard. Theturret is normally fabricated in two sections, the first is incorporated into the hull and the second is lifted onlater. Structural sections are prefabricated and assembled, either on the hull or separately for later lift intoplace. The topside facilities are normally manufactured in pre-assembled units, modules or pallets. Thehull and upper turret, topside facilities and other equipment are delivered to an at-shore assembly site forhook-up, mechanical completion and testing prior to proceeding to the production site. All onshoreconstruction and fabrication activities are expected to be carried out at existing industrial sites.4.5.2 Subsea FacilitiesSpecialized manufacturers will supply flexible line production and injection risers, suitable for use in theharsh environment at White Rose. The risers are typically supplied fully equipped and tested, and ready toinstall. Subsea manifolds and flowlines will gather the production and convey it to the risers. Manifoldsinclude headers, piping, valves, and control equipment, mounted on a base.Many proprietary well components will comprise high quality forgings requiring heat treatment, specialwelding procedures and precision machining. Tree installation will require special running and testingtools. Flowlines will be either flexible or rigid steel pipe. Flexible flowlines will be prepared by themanufacturer, ready for installation. Rigid steel pipe will be manufactured by mills in lengths appropriateto transportation and handling constraints, and the limitations of the lay barge. Consideration will be givento the option of installing the flowlines in cased bundles. In that event, the flowline bundle will befabricated on-shore at a suitable construction site. Another option, which may be examined for rigid steelpipe, is welding them into long strings on-shore and winding them onto spools on a reel lay vessel foroffshore installation.Depending on their size, manifolds may be installed either directly through the moonpool of a semisubmersibledrilling unit or, if small enough, from the deck of a support vessel with sufficient liftingcapacity to handle lowering them to the seafloor, where they could be picked up and placed by a drillingunit.A dynamically positioned vessel, equipped for flexible pipe and cable installation, will be used to installthe risers and flowlines. Divers may be used to make the subsea connections.Wellheads will be installed in the glory holes through the moonpool of the drilling unit. Upon completionof the well-drilling operation, the drilling unit will also be used to install the subsea trees. Final connectionof the wells to the manifolds by jumper spools will be carried out by divers.White Rose DA Project Summary • January 2001 Page 59
