Trusted Solutions for Deep Water DrillingReliable, low risk, proven

IntroductionFor over 30 years Sonardyne havebeen pioneers in the use of subseaacoustics for navigation, positioningand communications.

Today, these systems are installedon many of the world’s deep waterdrilling vessels, positioning themin over 3,000 metres while,simultaneously providing downholedata logging, emergency BOPcontrol and riser angle monitoring.

With the progress into still deeperwaters and greater technicalchallenges, Sonardyne’s costeffective and trusted solutions willcontinue to meet your requirementstoday and offer innovative solutionsfor the future.

The primary role for an acousticpositioning system on a mobile deepwater drilling unit is to providereliable and accurate positionreference data for the vessel’sdynamic positioning system.Requirements for dual redundancy,riser monitoring, multi-vesseloperations and BOP controlare demands that further extendthe role of acoustic technology.

Sonardyne is meeting thesechallenges with its Wideband™

signal technology, the first step-change in performance sinceacoustic positioning was introduced.

Wideband™ signals use phasemodulated codes transmittedon one of many different carrierfrequencies. This combinationgenerates more than 400 trulyindependent operating channels.Using Digital Signal Processing(DSP), dramatically improved rangeperformance is achieved evenat the lower signal to noise ratiosexperienced in the acousticallynoisey environment createdby vessel thrusters.

Wideband™ acoustic signalsare fundamentally more robustthan traditional analogue signalsand are, therefore, better suitedto realtime monitoring applicationssuch as the acoustic telemetryof BOP and riser monitoring data.Crucially, because the restrictedbandwidth is used more efficiently,more individual operating channelsare available enabling more usersto work in the same locality withoutcausing acoustic interference.

For example, a rig can operatesafely on DP whilst acoustic surveyoperations are conducted from othervessels in the field without the risksassociated with acoustic pollution.

Wideband™ telemetry also offerssignificant improvements in theefficiency of deep water operationsby greatly improving the updaterate for the positioning of structuresas they are deployed to the seabed.

Wideband™ LUSBLDual independent multi-user capability

IntroductionDevelopments in deep water fieldshave led to an increasinglycrowded operating environment,with multiple DP vessels requiredto work within acoustic interferencerange of each other.

As DGPS suffers from scintillationor signal interference caused bysunspot activity, a demand hasbeen created by operators for DPdrilling units to adopt the use oftwo independent acoustic systemsfacilitating automatic weightingof acoustics against multiple DGPSreferences within the DP desk.

Sonardyne’s new dual independentWideband™ LUSBL system not onlymitigates the problemsof interferencebetween vessels but it also allowsmultiple systems performing differenttasks to be operated on the same rig.

The system achieves this through theavailability of over 400 navigationchannels, delivering true multi-operation capability in crowdedfield environments. The technologyis also capable of providinggreater immunity to noise, a tenfold improvement in rangemeasurement repeatability and fastposition update rates when loweringstructures onto the seabed.

Wideband™ LUSBL can also beset-up as a conventional dualredundant system where two systemsare cross-linked in a ‘master andslave‘ configuration. This allowspositioning to continue in the eventof a single point of equipment failure.

LUSBL UpgradeUsers of existing Sonardyne LUSBLsystems are now able to takeadvantage of the latest Wideband™

signal technology with an easyand cost-effective upgrade.

As the Wideband™ LUSBL upgradeis installed on existing hardware,operators benefit from the newtechnology whilst the vessel remainsin service. The use of familiarhardware and software on a proventopside platform eliminates theneed for re-training and enablesusers to work with confidence fromthe outset.

This low risk approach ensuresoperators can make a smoothtransition to wideband whilstmaintaining compatibility withtheir previous generation acoustichardware. Sonardyne is also ableto offer a range of options forupgrading other manufacturers’acoustic systems to Wideband™

including transceiver installationkits and flanges.

LUSBLLUSBL systems combine the highaccuracy of LBL positioning with theconvenience of USBL. The combinedranges are used to calculate the LBL

position of the rig and, in addition, theranges and directions to eachtransponder provides a USBL positionfrom each beacon

Multi Vessel OperationsSonardyne’s mutli vessel architectureavoids acoustic interference problemscaused by vessels operating similarsystems within close proximity toeach other

Dynamic PositioningWideband™ LUSBL can be interfacedto all industry standard DP systems,providing stable and repeatable acousticposition reference

Transponder DeploymentDeployment of a Compatt 5 seabedtransponder; Sonardyne’s most advancedWideband™ transponder featuring highpower transducers, long life battey packand high speed telemetry

LUSBL PositioningThe Long and Ultra-Short BaseLine(LUSBL) positioning technique isparticularly suited to deep waterapplications as it combines therepeatability derived from LongBaseLine (LBL) subsea positioning,where accuracy is virtuallyindependent of water depth,with the operational convenienceof Ultra Short BaseLine (USBL)positioning.

The high level of range redundancyensures that in poor acousticconditions in which deep waterDP vessels often operate, or whenrecovering transponders formaintenance, many rangemeasurements can be corruptedbefore the computed vesselposition degrades.

Sonardyne’s LUSBL designcircumvents the delays of calibratingthe LBL arrays by using a ‘TopDown’ calibration technique asthe transponders are deployed.By not having to take baselinemeasurements, arrays can becalibrated quickly and reliably.An important advantage of thisapproach is the uninterruptedsupply of acoustic information tothe vessel’s DP system. This canbe from arrival on station and thedeployment of the first transponder,through the array calibrationprocess and during the long termmaintenance of the array.

System PerformanceRepeatability, the most importantaspect when related to dynamicallypositioned rigs, is typically 0.5%of slant range although the absoluteaccuracy of the system is dependentupon the quality of attitude andheading sensors, transponder sourcelevel, vessel noise, water depth andmechanical rigidity of the transceiverdeployment machine and propercalibration of the total system usingSonardyne’s CASIUS calibrationsoftware package.

CASIUS is used to determinethe inherent errors or offsets thatare typically found within thevessel’s various attitude sensors.Compensating for these errorsand offsets, together with the useof high resolution VRUs and gyro’s,can improve the repeatability toas little as 0.2% of slant range.


Wideband™ LUSBLSystem Overview

System OverviewA standard Wideband™ LUSBLsystem is comprised of four maincomponents; a rack mountedNavigation Processor, controlsoftware, acoustic transceiverand a subsea transponder array.

In a dual independent system,the vessel is equipped with twoseparate sets of topside hardwarethat can share the same seabedarray. In a dual redundant system,the Navigation Processors andtransceivers are cross-linked intoboth DP desks.

Navigation ProcessorTheNavigationProcessor commandsthe transmission of acoustic signalsfrom the through hull transceiver tothe transponders, decodes the datareceived back and formulates theappropriate telegram to pass tothe DP desk. The unit also processessignals from VRUs, Gyro Compass’and DGPS.

The operator interface consists of arack mountable TFT colour monitorand keyboard. This facilitates

system initialisation, whereby jobspecific parameters can be changedand positioning tasks monitored.Alternatively, the LUSBL display canbe integrated within a customer’sown DP console.

LUSBL SoftwareThe Wideband™ LUSBL software isan embedded software applicationdesigned to manage the complexcommands and communicationsbetween multiple transceivers andmultiple transponders whilstproviding users with the highestlevels of operational flexibility.

Features include diagnostic toolsto optimise system performance,‘pole flap’ monitoring to analysevibration from deployment systems,attitude sensor calibration, waypointcalculator and support for HPR309, HPR 418 and 418BCDtelegram types.

TransceiverSonardyne Wideband™ LUSBLtransceivers are optimised tooperate with Compatt 5transponders and are backwardly

compatible with the tone channelsof Compatt 4. The transceiveralso functions as an LBL transceiverremoving the need for additionalvessel hardware.

There are two transceivers to choosefrom depending on the vessel andthe operational environment. Type8021 or ‘Standard Head’ is an allpurpose transceiver best suited togeneral survey and DP operationswhere tracking could be straightup and down or at shallow angles,for example, towfish tracking.

The Type 8023 or ‘Big Head’transceiver is the more commonchoice for LUSBL operations asit is specifically designed for ultra-deep water and the high noiseenvironments typically associatedwith mobile drilling units.

The unit is optimised to receivesignals arriving within a ±50° cone.Any noise generated outside of thisarea, for example by thrusters,is rejected, therefore improvingthe signal to noise ratio and sothe positioning accuracy.

Navigation ProcessorThe Navigation Processor is a 19 inchrack mounted unit that commands thesystem. It is interfaced to the vessel’s DPsystem, VRU, gyro, GPS and acoustictransceiver

Dual Independent Configuration Sonardyne LUSBL can be configuredas a dual independent or dual redundantsystem depending on the operationalrequirements of the vessel


05

LUSBL TransceiversSonardyne offer a choice of either‘Standard’ or ‘Big Head’ LUSBLtransceivers depending the vessel,operating depth and acoustic noiseenvironment

Compatt 5Compatt 5 is Sonardyne’s mostadvanced LBL transponder with optionsfor high power transducers and 7,000metre depth ratings

Back Deck TestingCompatt 5 and DPTi transponders canbe tested on the back deck withdedicated test units

Transponder OptionsSonardyne LUSBL systems arecompatible with the vast majorityof medium frequency transponderscurrently in use worldwide.However, optimum performance isattained when using transpondersthat have been designed withWideband™ technology.

Compatt 5Compatt 5 is Sonardyne’s mostadvanced LUSBL transponderfeaturing high speed telemetry,release mechanism and long life.

Standard features include highlyreliable acoustic release mechanism,depth ratings of 3,000, 5,000 and7,000 metres, four different housinglengths (Mini, Midi, Standard andMax), dual axis inclinometers withDigiQuartz depth sensors, directmeasurement sound velocity sensorand the capability to interface toand power external equipmentfor data telemetry to the surface.

Wideband™ Compatt 5 transpondershave been validated in an extremerange of operational environments.This has confirmed that the fasterand more rugged Wideband™

signals provide the highest accuracyand therefore the lowest risk for allsubsea acoustic positioning tasks,regardless of water depth.

Back Deck Test UnitsCompatt 5 and DPTi transponders(see Page 10) are supplied with PCutility software that allows users toset-up and program the transpondersprior to deployment.

In addition, a dedicated Deck TestUnit (DTU) or Pocket Test Terminalare also available. Supplied ina rugged portable case, theDTU is used initially to programthe channel of the transponder,acoustically test the transponderin air and then load the acousticrelease mechanism.

Pocket Test Terminal is a new trulyportable test tool. Running onan iPAQ PDA platform, the PocketTest Terminal software offers all themain features of the PC-based utilitysoftware but from a small, portable,splash proof device. It is thereforeideal for taking on to the back deck.

Transponder Floatation CollarsSonardyne supply a range ofsubsurface floatation collars thatare compatible with Compatt 5transponders. Manufactured fromhigh performance materials specificto the depth rating required,Sonardyne floats are designed forease of handling on the back deckand come in bright colours to ensurehigh visibility both underwater andduring recovery.


Transceiver Deployment MachineUltimate Performance

IntroductionAt best, the accuracy of an LUSBLpositioning system can be seriouslydegraded by poor attention todetail in the mounting of thetransceiver. At worst, it could posea hazard to the integrity of the vesseland place people and valuableassets at risk.

Key Features

• High strength carbon steel pole for stiffness and strength

• Inconel™ coating for durability and corrosion resistance

• High integrity bearing and sealing design

• Configurable design, can be Zone 1 Ex rated

• Reliable hydraulic actuation with safety interlocks

Sonardyne’s through-hull StandardDeployment Machine consistsof a hydraulically operated pole,a sealed bearing section and a seachest service section with inspectiondoor. The whole machine sits on agate valve which in turn is mountedon the hull penetration flange.

Sonardyne have completedin excess of one hundred successfulvessel installations worldwide,ranging from simple new buildsto very complex installations intoresearch vessels. All of theseinstallations have been foundedon sound engineering practiceimplemented by experiencedengineers in collaboration withclients, naval architects andshipbuilders.

Local Control PanelThe machine can be controlled from abridge or local control panel

Hydraulic Power PackProvides power to raise and lower thepole. Features include pressureregulation, motor and oil level indicator

The ideal deployed lengthis dependant on each particularapplication but in general termsit is best to minimise the deployedpole length to achieve the requiredacoustic performance.

Typically, a length of between oneand three metres below the hullhas been found to be suitable. Thepole is very rugged and is designedto be highly resistant to vibrationcaused by vortex shedding.

Continuous operational speedsof up to ten knots through the watermay be achieved safely (refer toseparate brochure for fullspecifications) with the abilityto survive short duration exposureto higher speeds.

Sonardyne can give detailedapplication advice on positioning,installing and commissioning themachine, backed up by worldwidefield support from experiencedcommissioning engineers.

The gate valve, when closed,provides easy access to theretracted transceiver for serviceand inspection purposes via thedoor fitted to the service section.The gate valve also allows thetransceiver to be removed withoutdry docking.

Available options for the gate valveinclude different materials, hydraulicor manual drive and a right angledrive adaptor.

The machine can be controlledfrom the vessel’s bridge usinga main control panel or from alocal panel at the machine. Thehydraulic power pack and localcontrol can be mounted remotelyif the machine is to be configuredfor Zone 1 Ex classification.

The standard form of machine canbe simply customised to meetindividual vessel requirements bychanging the height of the machineand providing adaptor flanges fordifferent size or specification valves.

For specialist or demandingapplications machines of this generaltype can be custom engineered tosuit customer specific requirements.


Wideband™ Acoustic Data LoggerHigh speed, robust communications

IntroductionWellhead logging of down-holedata and cable-less telemetry arecore Sonardyne technologies thatoffer guaranteed performance andreliability. The cost of deep waterdrilling and the complex geologyof many of the world’s deep waterfields has increased the demand forwell testing during field appraisal.This is frequently carried out fromremote observation wells with nocabled connection to retrieve down-hole data.

Sonardyne’s subsea data loggerprovides the solution by allowingthe down-hole data to be storedat the wellhead and uploaded ondemand, via its cable-free acousticdata link.

Key Features

• Designed for ROV deployment and retrieval

• Easily moved between wells

• Uses Sonardyne’s latest Wideband™ signal technology

• Interfaces to all industrystandard gauges

• Depth rated to over 10,000 feet (3,000 metres)

• Fully adjustable data logging rate

• Long-life seabed deployment

Sonardyne’s new generation ofsubsea acoustic data logger systemuses a Wideband™, high speedacoustic link to allow large volumesof logged data to be rapidly andaccurately retrieved at the surface.

When combined with the featureof ROV portability, the system isthe ideal solution for initial wellappraisal, where frequent downholepressure and temperature readingsneed to be logged over a periodof a few weeks.

The system is equally suitablefor long-term deployments whereit may remain installed on awellhead, logging data for severalyears without intervention.

The unit is capable of interfacingto downhole gauges from all ofthe major suppliers such as;Schlumberger, Well Dynamics,Roxar and Baker Hughes. Othermanufacturers’ gauges can alsobe interfaced when required.

Proven Track RecordSonardyne data loggers have beendesigned to meet the challenges ofcomplex offshore projects which are

increasingly using subsea completions toprovide a cost effective solution tooperating in deep and marginal fields

ROV Mateable (Below and Right) The data logger unitfeatures a ROV mateable connector.Alternatively, the unit can be connectedto a jumper cable prior to deployment

Data Logger Unit Constructed from super duplexsteel, the data logger unit is ratedto a depth of 3,000 metres and issuitable for either long or shortterm deployment. The connectoron the side of the data logger maybe ROV-mateable or may beconnected to a jumper cable priorto deployment.

Logging intervals can be varied byacoustic command from 1 minute to7 days and is essentially governedby the battery power consumed bythe gauges and interface circuitryeach time a measurement is made.

Using a standard battery, the lifewill be greater than2years if gaugesare read only a few times per daybut may reduce to a few weeks ifgauges are read every few minutes.

Memory capacity is 8Mb whichallows 500,000 data samples tobe recorded. In general, the batterylife is usually a greater constraintthan memory size.

Surface TransceiverThe surface transceiver unit hassimilar characteristics to the subseaunit and contains a directionalacoustic transducer and thetransceiver electronics.

It is designed for a high level ofnoise rejection from the rear andside, enabling it to receive acousticsignals very effectively in thepresence of thruster noise.

The transceiver is typically deployedfrom a small crane or some otherover-the-side deployment scheme.It can also be permanently mountedon a vessel through a gate valveand deployment machine.

Surface Interface Unit andControl ComputerThe surface system is designedto operate with a standard laptop interfaced to the transceiver viaa Surface Interface Unit thatprovides DC power and a serialcommunication interfaceto the transceiver.

The PC software supplied is anapplication program running underthe Microsoft Windows operatingsystem. Automatic retrieval of dataand setting of the loggingconfiguration is initiated by virtualbutton presses and selections fromsimple dialogue boxes.

Gauge coefficients are importedfrom disk and the data convertedinto engineering units before beingstored on hard disk for export toa file in spreadsheet format.


Marine Riser Angle Monitoring SystemSystem Overview

IntroductionSonardyne’s Marine Riser AngleMonitoring System (MRAMS) is ahighly accurate, cable-free solutionfor measuring the differential angleof a marine riser, BOP assemblyand vessel’s position relative to it.

Developed from field provencomponents, the system is based onthe integration of Sonardyne’s USBLacoustic positioning technology andBOP-mounted transponders fittedwith high resolution inclinometers.This provides clear and unambiguousdata on the vessel’spositionandriserangle status.

The monitoring system comprisesof four key elements; a NavigationController and Computer forcontrolling the transmission anddecoding of acoustic signals,a vessel based transceiver whichacts as an interrogator/receiverand responds to commands fromthe Navigation Controller, and apair of DPTi transponders; one fittedto the riser and one fitted to the BOP.

On command from the NavigationController one of three angles canbe measured; the Riser, the BOPor Differential Riser/BOP angle.The angles are measured andtransmitted to the surface usingacoustic telemetry. The data isdecoded by the transceiver andtransmitted to the Navigation

Controller which uses the elapsedtime from command transmissionto reply and phase comparisonto enable the vessel’s positionrelative to the BOP and riser tobe determined.

The system recommends a bearingfor the rig to steer to in order tominimise riser inclination relativeto the BOP.

The MRAMS software is simpleto learn, set-up and operate andallows users to achieve immediatesuccess and get to work withoutdelay or additional stress, which isoften associated with new systems.

Wideband™ Emergency BOP Control SystemSystem Overview

IntroductionSonardyne’s Emergency BOPControl System is a self contained,high security acoustic command andcontrol backup system. In the eventof loss of normal communicationswith a BOP stack, the system is usedto execute emergency shutdownand riser disconnect procedures.

Features of the system which ensurereliability and security includeWideband™ signal technology,forward error correction techniques,directional subsea transducers anda portable surface controller withdunking transducer which enablesremote operation from a lifeboator stand-by support vessel.

The system consists of a rackmounted or portable BOPCommandUnit, intelligent Deep AcousticRemote Transducers (DARTs)programmed to receive, decodeand validate acoustic commands,and a Subsea Electronics Module(SEM) that provides the interfaceto solenoids and read-back sensors.

The BOP Command Unit generatesacoustic commands in responseto operator intervention andtransmits them via a simple over-the-side or hull-mounted transducerto the DARTs.

The DARTs are usually located onfolding arms which extend outwardswhen the BOP is lowered from thevessel. This ensures a free path ofcommunications with the surface.Each system has a unique addressand its 2 DARTs are programmedto respond only to commands whichare specifically addressed to them.

Once decoded and validated,the acoustic commands from thesurface are forwarded to the SEM,which in-turn activates solenoidvalves which operate the hydraulicrams and close the stack down. Upto 12 function outputs operate thesolenoid valves which control thehydraulic operation of BOP Rams.

A single command cycle canbe selected which initiates apre-defined sequence of valveoperations, considerably speedingup BOP shut-in and disconnectoperations in an emergency.

BOP Command UnitThe BOP Command Unit is a fullyself-contained, high security acousticcommand and control unit. It can be rack

mounted at any convenient position onthe drilling vessel or supplied in a ruggedcase for portable operation from aremote location

Subsea Electronics Module The SEM is interfaced to the BOP’ssolenoids and read-back sensors.The unit is constructed from SuperDuplex Stainless Steel and is depthrated to 4,000 metres

Dunking Transducer(Bottom) The system’s dunking transducercan either be deployed over the side ofthe vessel or permanently hull mounted
