This is an area where Balmoralhas made significant technological advances.The use of conventional cast compositebuoyancy packs still has many commercialbenefits for large vehicles used for trenchingof pipelines or submarine cables. However, fordeep dive work class ROVs, operating beyond2000msw, the performance benefits ofBalmorals LDF series becomes significant.This low density, pure foam compositeprovides the operator an opportunity toincrease the uplift (buoyancy) of the vehiclethereby resulting in increased payloadcapacity. It also provides an opportunity toreduce the size of the buoyancy modulesthereby reducing the overall weight anddimensions of the vehicle.Balmoral LDF buoyancy is available from stockfor operating at depths to 7000msw.Balmoral also supplies ROV supportequipment for use on the umbilical systemsincluding floats and FlexLinkTM, a buoyantumbilical bend control system.Balmoral Ofshore EngineeringMarine subsea14A composite buoyancy system refers to a syntactic foam comprising glassmicrospheres and macrospheres held together within an epoxy resin system tocreate a homogenous matrix.Composite buoyancy systems are cast using dedicated mould tooling providingrepeatable consistent production and are therefore ideally suited in applicationssuch as work class ROVs - particularly on a multi-build requirement.Each component within any given Balmoral syntactic foam is individually ratedfor specific operating depths resulting in a strong, lightweight compositeformulation.There is an overlap in the operating depth ranges which is caused by macroefficiency changes in design operating depths. This means that more efficient,lower density composites may generate improved uplift for a given volume asthe operating depth increases.Composite buoyancy systems comprise an integrated shell to ensure maximumprotection of the core material in the event of accidental impact.Composite foam systemsPure foam ultra-low density range (LDF)3250/10003956500/20004359850/300045013100/400047016500/500049023000/7000565 32800/10000640Typical operating depth ft/mswTypical core density kg/m3Pure foams offer many advantages over macrosphere composite foam systemsincluding robustness, ease of repair and modification in the event of damage ordesign changes, and extremely low water ingress rates.It should be noted, however, that this is a premium product and is therefore typicallyselected for more demanding service conditions such as extreme operating depthsand/or service criticality such as manned service.The ultra-low density range of pure syntactic foam is normally produced in pre-castblocks. These blocks may be supplied for client assembly or can be factoryassembled into finished buoyancy modules.The buoyancy performance of Balmorals ultra-low density material is understood tobe unique amongst ROV buoyancy foams in that the buoyancy does notprogressively reduce due to hydrostatic compression as the ROV moves into deeperwater. This is because the bulk modulus - ie, the compressibility under hydrostaticpressure of the foams is marginally less than sea water.Pure foam systemsDuring 2013 Balmoral Offshore Engineering introduced anin-house ROV buoyancy block milling capability.Taking internal control of this process allows Balmoral tocreate intricate ROV PFS and LDF buoyancy profiles withvirtually no size limitations using its 5-axis CAD/CAM-controlled milling machine.ROV buoyancy machining and millingMarine subseaBalmoral Ofshore Engineering 15Selecting a coating for buoyancy modules of any type is a critical issue. These coatings provide impactand abrasion resistance while offering a high visibility smooth gloss finish.The most frequently supplied ROV/AUV coating is a 3-5mm spray-applied elastomer which is appliedto all upper and external surfaces to give a very effective finish, particularly for work class vehicles.Standard finishes are provided in high gloss yellow, orange, red or white. Other colours are availableto suit project parameters. An extremely high quality smooth finish is available for specialisedapplications.Where a quantity of modules of the same generic shape is required, in applications such as skidmodule blocks or trim modules for example, Balmoral provides an alternative to PU or GRP skins byutilising rotationally moulded polyethylene shells.Polyethylene is a material used extensively in the offshore industry and these shells can bemanufactured for heavy duty applications with thicknesses ranging from 6-14mm.Provision should be made within the design to accommodate the tolerances applicable to rotationallymoulded products.ROV/AUV external nishingFlexlink was developed to meet the needs of large, tracked, trenching vehiclesthat operate on the sea bed.To prevent such vehicles damaging their control lines, FlexLink is installed at thetether point to provide a continuous, articulate buoyant section above thevehicle, thereby ensuring the umbilical remains out of the vehicle work zone atall times.FlexLink is used as a permanent installation which is designed to pass throughthe sheave wheels of launch and recovery systems (LARS). It is supplied forinstallation onto umbilicals ranging in size 25-75mm OD while the buoyancy canbe specified to suit project requirements.Typical uplift ranges from 6-12kg/m in design operating depths of 0-6000msw.FlexLink umbilical buoyancyBOE provides a range of floats to suit most control umbilicals. These floats comprise a pair ofsymmetrical half shells which are profiled to permit the line to flex within its specified bend radius.Each float is manufactured using a low density composite foam core covered in a high performanceimpact and abrasion resistant polyethylene shell.BOEs umbilical floats are hinged using two stainless steel latches. The floats are designed to grip theumbilical by means of a natural rubber internal grommet.Balmoral umbilical floats are designed to suit umbilical diameters ranging from 25-50mm OD.Umbilical floats can be supplied to suit larger diameter umbilicals where required.Umbilical oatsBalmoral Ofshore EngineeringMarine subsea16Cable and owline protectionBalmoral Duraguard provides a cost effectivelocalised impact and abrasion protectionsystem and is supplied as pairs of interlockinghalf shells secured around the core productusing circumferential straps.It is manufactured in a range of polyurethaneelastomer grades, depending on the specificoperational conditions, and can be supplied ina wide range of diameters, thicknesses andlengths. Typical lengths are determined by theindividual half shell weight and can vary from500-2000mm.Balmoral provides four differing systems: Duraguard Standard DuraguardPlusAs Duraguard standard but supplied asone-piece hinged modules with integratedbanding system Duraguard HD ballast system DuramatDuraguard was developed for the protection of subsea cables, flexible jumpers, flexible flowlinesand riser touchdown zones although many other applications have been identifiedMarine subseaBalmoral Ofshore Engineering 17For projects which demand cable protection with added ballast, Duraguard HD (High Density)ballast system provides much more than straightforward abrasion and impact resistance.Heavy filler materials are added to the Duraguard mix to increase density and overall weight. Theballast provided gives extra on-bottom stability while the added mass improves dynamic responsethus reducing the risk of clashing.Densities ranging from 2300-8000kg/m3can be achieved with the Duraguard HD ballast system.Duraguard applicationsBallastFiller materials can be added to increase density and provide extra stability.BuoyancyStandard PU is practically neutrally buoyant in seawater. However, hollow microspheres can beadded to reduce density and provide uplift ranging typically from 650-800kg/m3.Impact absorptionPU is a relatively resilient material which can absorbmoderately heavy impact. Reinforced options areavailable for extreme environments.ProtectionProtects risers from abrasion/gouging at touchdownpoints, over rough seabeds, coral or rock.StiffeningDuraguard provides added stiffness to support cableover the seabed and/or assist in laying operations.Thermal insulationLab tests have shown a significant increase in thermal insulation performance when Duraguard isfitted.Duraguard installationDuraguard can be fitted during unreeling/laying or prior to reeling and is installed by placing thetwo modules around the flowline and banding them into place.Incanell or titanium bands are normally set 300mm apart. Adjacent segments with overlapping endsare added to provide a continuous protected length.Duraguard HD ballast systemDuramatMoulded in marine grade polyurethane elastomer, Duramat provides dropped object impact andabrasion protection to seabed umbilicals, flowlines and pipelines.During manufacture, the PU is filled with barites that provide ballast and prevent tidal movementwhile the grooved element design allows flexing and separation of the protected lines.Duramat is ROV and diver installable and is generally supplied with through holes for ropehandling. Typically provided in 3000x3000x40mm sections, the mats can be custom sized to meetproject specifications.Balmoral Ofshore EngineeringMarine subsea18Balmoral Subsea Test CentreBalmorals test house facility offers a comprehensive range ofprocedures including hyperbaric, mechanical and laboratory trialsPredominantly used for in-house testing anddevelopment work these facilities and servicesare also available to external customers.The facility provides the industry with a fullycomprehensive resource for buoyancy and PUmaterials and product testing - from conceptthrough development and deployment.Hyperbaric testingSubstantial investment has been made inimproving and expanding the BalmoralSubsea Test Centre which now offers thelargest commercially available hyperbaricvessel in Europe.Upgraded vessels, software and proceduresare in place offering independent testing forall types of subsea equipment to 7000mswequivalent.Standard tests include: Uplift determination Water ingress Instrumented buoyancy loss Hydrostatic compression and creep Hydrostatic collapse Bulk modulus Buckle arrestment performanceThe hyperbaric vessels use air driven liquidpumps and can accommodate electric,hydraulic and instrumentation connections.Each vessel can be fitted with chart recorders,pressure and temperature data loggers thatprovide highly detailed results for analysis.Balmoral hydrostatic testing facilitiesPV1 5200 35835 61082552-- 1320HorPV210000 7007 9238019-- 485VertPV310000 7007 9238019-- 485VertPV410000 7007 9238019-- 485VertPV510000 7001---3005.5 140VertPV6 6000 41029 6 900072--1830VertVessel Safe workingpressureInternal lengthOrien-tationpsi bar ft/in mm in mmInternal diaDisplacement tanks are available for large scale uplift testing.Internal dimensions of the two tanks are: 6250x2250x1300mm deep 9800x2500x2750mm deep (unfilled weight 16 tonne)Marine subseaBalmoral Ofshore Engineering 19Mechanical testingA multi-purpose load rig, capable of performing axial slip loads, lateral and static loading,three-point bending and clamp overload tests is also available.Development laboratoryThe laboratory at Balmoral Offshore Engineering is equipped with state-of-the-artdevelopment, testing analysis and inspection apparatus.Managed by a highly experienced and dedicated technical team the lab plays a centralrole in the companys R&D programme.
