SpoolTree™ Production Systems

SpoolTree System Valve Assembly ConfigurationsIn the Cameron SpoolTree design, the spool body provides outlets to attachproduction, annulus and isolation valves for downhole functions and theelectrical penetrator bonnet assembly. The tubing hanger landing shoulder is specially ported to accept control stabs and provides hydraulic continuitybetween the production control system and downhole hydraulics.

The valves are contained both as an integral part of the spool body, and in mini-blocks external to the vertical bore of the tree. A typical valve clusterincludes production and annulus master valve, production and annulus wingvalve, crossover valve, workover valve and isolation valves for SCSSV, CIV andother requirements. Assemblies are available for 3" through 7" completions.

Basic Chemical Injection Annulus Crossover

Gas Lift ChokeProduction Choke

The Cameron SpoolTree Production System is one of the most widely usedtrees in the world and offers many time and cost saving advantages overconventional tree systems.

Instead of the typical wellhead-hanger-tree stackup, the SpoolTreedesign has a wellhead-tree-hanger stackup. In this configuration, theChristmas tree consists of a concentric bore spool with a wellheadconnector below and a wellhead connector profile on top. The tubinghanger is hung off inside the spool on a dedicated load shoulder, and the

valves are situated on the side of the spool. No valves are in the verticalbore of the wellhead/tree system. The completion is run after the tree isinstalled and the completion can be pulled with the tree in place andflowline connections undisturbed.

MOSAIC SpoolTree Production Systems can be configured with a widearray of component choices. The possible combinations of components,available pressure ratings and sizes are virtually endless. The result is acost-effective system that can be adapted to virtually any subsea job.

Master Control Station (MCS)The MCS provides control and monitoring of the complete system,including surface and subsea installed equipment. Two complete and

segregated MCSchannel networkssimultaneously monitordata functions to andfrom each other, sur-face and subsea. Inthe event of a channelnetwork failure, theother continues toseamlessly operate thecontrol system. Thisdual redundant archi-tecture eliminatessingle mode failurepoints and the require-ment for bumplesstransfer from the failedto the healthy channelnetwork.

The MCS featuresopen-architectureelectronics with dual

Fast Ethernet links to the host control system (or serial RS-485 and choiceof topside communication protocol including MODBUS and Profibus). It is OPC v.2 compliant for compatibility with all other OPC v.2 compliantequipment. The MCS standard modems are qualified to control up to 10Subsea Control Modules at 24.9 miles (40 km) offset, and the standardMCS can accommodate up to eight modems per channel. Ultra-longoffset capabilitiy is assured by lowering the number of SCMs.

Electrical PowerUnit (EPU)The EPU providesconditioned electricalpower to the topsideand subsea systemcomponents. The EPUsupplies dual, isolated,single-phase power forthe subsea systemthrough the compositeservice umbilical,together with powersupply modules for theMCS and HPU.

Hydraulic PowerUnit (HPU)The HPU providesredundant low- andhigh-pressure hydraulicsupplies to the subsea system. Self-contained and totally enclosed, theHPU includes duty and backup electrically driven hydraulic pumps, dualredundant filters, accumulators, and control and instrumentation for eachLP and HP hydraulic circuit. The unit operates autonomously under the

Master Control Station

control of its dedicatedprogrammable logiccontroller (PLC), whichprovides pump motorcontrol, interlocks andinterface with theMCS.

Topside UmbilicalTermination Unit(TUTU)The TUTU provides theinterface between the topside control equipment and the main umbilicalsystem. This fully enclosed unit incorporates electrical junction boxes forthe electrical power and communication cables, as well as tube work,gauges, and block and bleed valves for the appropriate hydraulic andchemical supplies.

Subsea ControlModule (SCM)Rated for waterdepths up to 10,000ft (3000 m), theCAMTROL SCM is theheart of the subseasystem. The SCMweighs less than 2200 lb (1000 kg)and measures only

29" x 29" x 34" high (736 mm x 736 mm x 860 mm high), making it thelightest, most compact control module in the industry. This allows easyinstallation and intervention by standard work-class ROVs with any of theCAMTROL suite of Multi-Mode Running Tools. Yet with up to 32 controlfunctions, 24 external (4-20 mA) electrical sensor inputs and availablemulti-dropped intelligent completion capability, the CAMTROL SCM leadsthe industry in functionality and future potential. This can reduce thenumber of SCMs needed for an entire project, thereby lowering capitalexpenses.

The SCM provides multiplexed electro-hydraulic control and monitoringof a wide variety of field functions including traditional tree functions,manifold valve control, choke adjustment, position indication, headerpressure/temperature monitoring, downholeintelligence monitoring, sand detection,corrosion monitoring and multiphase flowmeasurement. Other features include:• Oil-filled, pressure-compensated

construction designed for 14˚ to 122˚ F (–10 to+50˚C); controlled-environment electricalconnections; seawater-tolerant materialsavailable throughouthydraulic system

• Diverless or diver-assisted designs

• 3000 or 5000 psi (207 or 345 bar) nominal supply pressures for treeand manifold valves; 5000 or 10,000 psi (345 or 690 bar) supplypressure for SCSSV and other HP needs

• Dual SEMs with dual valve electronics modules are standard • HydraQuad Couplers feature pressure-balanced shear seals which,

when combined with Cameron directional control valves, providevirtually leak-free operation for lower opex and less non-productivetime.

Subsea Distribution Unit (SDU)The modular CAMTROL design allows the SDU to be either separate orfully integrated. The SDU provides the hydraulic, chemical and electrical

distribution betweenthe subsea system and the main controlumbilical. The struc-ture is designed, testedand certified to accom-modate all handlingloads. For deepwaterapplications, the unitcan incorporate hinge-over lock capability.All components are

suitably earth bonded and corrosion protected to suit the installation.Additional features include:• ROV or diver make-up flying lead jumpers• ROV or diver-operated block and bleed valves• Electrical distribution system with optional

diver or ROV replaceable fuses• ROV interfaces compliant with API 17H• Available with integral SCM and SAM

Subsea AccumulatorModule (SAM)The Subsea Accumulator Module(SAM) provides a local source ofhydraulic fluid. Each standard SAM is fitted with four 5.3 gal (20 l) LP and two 0.7 gal (2.5 l) HP accumulators, providingsufficient capacity to operate100% of all the valves on aproduction tree. The SAM has theidentical footprint, lockdown andtooling interface as the SCM andcan be replaced using any Multi-Mode Running Tool. All com-ponents are suitably earth-bondedand corrosion-protected via adedicated electrical connector.

Subsea Distribution Unit

Intervention FlexibilityThe CAMTROL system usescommon intervention methods for the retrieval and re-installationof the SCM, as well as the SAM,compact multi-phase flow meterand Cameron Willis SubseaRetrievable Chokes. Methods may include diver-assist, diverless,guideline, guidelineless and ROV-assisted.

Multi-Mode Running Tool (MMRT)Cameron Controls offers a suite of MMRTs, which performinstallation and retrieval of thesystem elements detailed above.The MMRT design allows theseoperations to be performed using common intervention methods — diver-assisted, conventional guideline, guidelineless or with an ROV — in

water depths to 10,000 ft (3000 m).The MMRT is designed for efficient

operation with a work-class ROV and isinterface-compliant with API 17H usingweight transfer systems for neutralbuoyancy.

Deepwater Liftline Running Tool(DLRT) Designed with the identical functionalityand capability of the MMRT, the DLRT isintended for applications without highcurrents or other problematic conditions.The DLRT is suspended by a liftline andcan be guided by an ROV.

Diver Change-Out Tool (DCOT)The DCOT is designed for diver intervention applications for a variety of change-out functions. Like the MMRT, the DCOT locates onto an API 17H weightreceptacle interfaceand is run on aliftline with orwithout guide wires.
