Uraduct®
4
Uraduct® is a patented product designed and developed by Trelleborg CRP. It has established an enviable reputation as an industry standard for cable and flowline protection. An intensive investment programme has resulted in Uraduct® becoming the universal protection system for fibre optic cables, power cables, umbilicals, flexible flowlines, rigid flowlines, hoses and bundled products. In areas where additional protection is required, e.g. rocky seabeds, touchdown locations, shore landings or cable/pipeline crossings, Uraduct® provides a high performance technical and cost -effective protection solution in comparison to alternative methods such as rock dumping or concrete mattressing. Uraduct® comprises of cylindrical half - shells moulded in a range of thicknesses from the most applicable grade of high performance polyurethane (see pages 16 & 17 for material specifications). The half - shells overlap and interlock to form close fitting protection around the core product. For ease of handling and transportation, Uraduct® is manufactured in lengths of up to 2.0m with flexing characteristics to suit the required minimum bend radius of the product or ancillary shipboard lay equipment. Uraduct®, a custom made system, is manufactured to suit the core product with internal diameters ranging from 15mm up to 950mm. Recent innovation programmes and client requests have lead to a number of key product developments in the Uraduct® range. Trelleborg CRP now offer a ‘multi-fit’ Uraduct® design which will accommodate a larger range of core product sizes. This solution assists clients in situations where exact core product sizes are likely to vary or are unknown.
5
The half - shells are secured in place using pre-cut corrosion resistant banding (see pages 14 & 15). The banding is located in recessed grooves that not only ensure a smooth external profile allowing passage through cable engines etc, but also eliminates the need to measure the band spacing. The assembly of the system is quick and efficient being applied simultaneously with product installation. This is a major benefit in weather dependent industries such as the oil and gas and submarine telecommunications industries. Uraduct® also differs from many alternative protection methods in that it becomes an integral part of the cable or pipeline and is a fully tested system with a proven track record, details of which can be supplied on request - Trelleborg CRP is Proven to Perform.
Extensive use in the oil and gas industry by most leading oil companies has made Uraduct® the automatic choice for aiding “crossing acceptance” where submarine telecommunication cables or power cables cross existing pipelines or cables. Uraduct® has been specified on an ever increasing range of projects, from flexible riser touchdown over coral seabeds to protection of small fibre optic cables where burial cannot be achieved. Although Uraduct® was originally designed for harsh offshore conditions; many of Trelleborg CRP’s customers appreciate how the protection properties of Uraduct® can also meet the needs of land based projects where operating conditions can be just as onerous. No other protection method can deliver the level of all round protection combined with the economic benefits associated with a Uraduct® installation.
Uraduct® +
6
In response to client requests and for applications where pipelines or cables are to be subject to high levels of abrasion, Trelleborg CRP has developed Uraduct® +, which is considered to be the ultimate protection solution. Flexible pipes, power cables and fibre optic cables can be protected in any area where abrasion is considered to be a problem and stabilisation cannot be achieved. This includes pipeline touchdown locations, rocky areas and shore landings. Uraduct + is moulded in Trelleborg CRP’s “super abrasion resistant” elastomer (see pages 16 and 17 for material specification) and offers all the characteristics of standard Uraduct® with the added benefit of encapsulating the securing bands to prevent premature wear or abrasion of the banding itself. ®
The polyurethane half - shell mouldings are supplied in loose pre-assembled pairs, with the securing bands fully encapsulated within the body of the PU protection system, with the exception of the seal arrangement. Uraduct®+ is installed onto the pipeline or cable in pairs, with the socket and spigot overlapping and interlocking each pair of mouldings in the assembly. The socket and spigots are designed with a ‘dove tail’ arrangement, ensuring full system integrity when subject to bending, during either installation or service. Uraduct® + is secured in place by 32mm wide x 0.8mm thick Alloy 625 banding. The same pneumatic band tools as used for standard Uraduct® are employed to tension, crimp and cut the bands, allowing for quick and simple installation.
The protection system is also designed to allow for the removal of the securing bands and replacement with new securing bands in the event that the protection system is to be removed and reinstalled on to a new riser system. Uraduct® + has undergone full factory testing to ensure that it is fully qualified to meet the stringent requirements laid down by its clients. Whilst utilising materials that have been field proven over a number of years, this innovative design has now taken cable and pipeline protection to new levels. No other product on the market can match Trelleborg CRP’s Uraduct® +. Trelleborg CRP is Proven to Perform.
Uraduct® -
Retrofit riser system
In response to the increasing number of additional cables requiring access to and from offshore platforms, Trelleborg CRP developed the Uraduct® Retrofit Riser System, which comprises of Uraduct® and dedicated, high integrity, locating clamps. This system provides a very cost-effective solution where cable access to a platform is not possible via existing ‘J’ or ‘I’ tubes. Prior to Trelleborg CRP’s Uraduct® Retrofit Riser System the only alternative was to install new steel ‘J’ or ‘I’ tubes at great expense, compounded with time consuming and problematic installation.
7
With the introduction of the Uraduct® Retrofit Riser System, substantial cost savings along with improved installation times have resulted in a number of projects coming to fruition which previously would not have been possible.
The securing clamps for this system are designed to withstand the extreme conditions experienced on offshore installations, and can be configured to suit multiple cables. Under normal circumstances the clamps are pre-installed onto a suitable platform leg or structure at regular intervals, the spacing being dependent on the security required. Alternative clamp designs are available where multiple cables are to be installed. The clamp bodies are manufactured from a high performance, rigid, marine grade polyurethane elastomer. No special welding equipment is required as the clamp bases are secured by means of a Polyloop™ high strength Kevlar/EVA coated strap and a highly corrosion resistant metallic tensioning assembly, typically manufactured in Zeron 100 or titanium. Trelleborg CRP’s Uraduct® Retrofit Riser System has been successfully installed on platforms off the coast of Trinidad, in the Gulf of Arabia, and in the North Sea. This trend is set to grow with particular relevance to submarine fibre optic cables and inter-platform power cables - Trelleborg CRP is Proven to Perform.
VIV Suppression In deepwater riser applications, the use of steel catenary risers (SCRs) is increasing. These risers can be subject to the complex phenomenon of Vortex Induced Vibration (VIV).
8
VIV is caused by the regular shedding of vortices in the wake behind a pipe in steady current. The flow naturally “locks in” to shed these vortices in the same pattern at the same frequency along a significant length of pipe. This “lock in” is measured by the spanwise coherence and can cause the pipe to vibrate. VIV causes accelerated fatigue damage and can give rise to problems such as pipe girth weld failure or premature pipe failure. Other applications prone to VIV are rigid steel flowlines unsupported over free spans and major deepwater field developments requiring a large number of thermally insulated pipelines etc. Trelleborg CRP have recognised this increasingly common problem and to suppress the damaging vibration forces to an acceptable level have put together a comprehensive analytical, design and engineering package complete with a number of highly successful VIV suppression products.
Trelleborg CRP analyse each potential VIV problem using specially developed Computational Fluid Dynamics (CFD) software and use the results to assist in the design and verification of a strake to suit the application. For existing lines a VIV suppression system can be retrofitted by divers or by Remotely Operated Vehicles (ROV’s) in deepwater. When Trelleborg CRP’s suppression strakes are applied, the VIV system profile practically eliminates periodic vortex shedding from risers and flowlines. Trelleborg CRP VIV suppression systems are made to order and can accommodate any likely riser/flowline diameter. The system has been supplied to suit a pipeline outer diameter of up to 924mm to date. Trelleborg CRP VIV Suppression Solutions incorporate the following products:
Uraduct® VIV Suppression Strakes Trelleborg CRP’s VIV suppression strakes combine the benefits of traditional Uraduct cable and flowline protection with an effective VIV suppression profile. The product is manufactured in marine grade polyurethane as two single split line mouldings and is easily installable utilising the well proven overlapping and interlocking concept.
ROV Installable Strakes Designed to established Trelleborg CRP design standards for VIV suppression strakes, Trelleborg CRP ROV installable strake covers are high performance composite covers with an attachable polymer strake profile incorporating the field proven hinge and ratchet locking mechanism (ROR - Remote Operated Ratchet) which allows the ROV to handle, open and securely close the covers around the pipeline. The covers are designed to be installed safely and efficiently in water depths to suit the deepest rated ROVs.
Fairings
ROV Installable Strakes
As part of Trelleborg CRP’s VIV suppression development programme, a patented fairing system has been introduced as the latest in the VIV suppression product line. The fairing module is fixed onto the riser by a system of hinged clamps which allow the module to freely rotate around the riser to align with the current flow and shed the damaging vortices.
Fairings
Integral Strakes Trelleborg CRP are able to mould strake profiles into any of its products during manufacture. This is ideally suited for Trelleborg CRP thermal insulation shells, where a strake can be moulded in to provide effective VIV suppression.
The Trelleborg CRP VIV suppression system functions by introducing threedimensionality into the flow. This disrupts the spanwise coherence of vortices that might be shed, leaving the wake stable and steady.
The software is an invaluable tool during the fine tuning of a VIV system design. It provides the optimal balance of drag and vortex suppression utilising the given environmental data for each specific project.
To assist in the optimisation of a solution for any given project, Trelleborg CRP has invested heavily in specialised Computational Fluid Dynamics (CFD) software to obtain a comprehensive understanding of the required geometry and calculate the best strake profile for a VIV suppression system.
Trelleborg CRP will also verify or comply with customers own strake designs to produce a bespoke system.
9
The analysis has been supported by wet tank and model testing and forms part of a continuous programme of product development.

Polyspace™ -

350mm clearance at crossings
When laying subsea cables there is often a requirement to maintain a positive clearance between cables and existing pipelines at crossing points. Methods such as pre-lay rock dumping, concrete mattressing and steel structures are expensive, time consuming and difficult to place accurately. These options may also be unacceptable to the pipeline owner. As a solution, Trelleborg CRP has developed Polyspace™, a product that generates a 350mm clearance between the cable and pipeline. This system is flexible and comprises of interlocking hollow half-shells fastened around the cable by a combination of corrosion resistant metallic banding and sacrificial banding. The half-shells are manufactured from UV stable, marine grade, high density polyethylene which has good impact strength and abrasion resistance. Each moulding is free flooding and can be supplied with a ballast system to provide up to 90kg/m of additional submerged weight to suit the application.
Polyspace™ is installed onto the cable as it is deployed from the cableship at the crossing location. Internal cable clamps are used to lock the Polyspace™ mouldings onto the cable at regular intervals. ‘Leading’ and ‘trailing’ bending stiffeners can also be included with the system to prevent the cable exceeding the recommended minimum bend radius at any time during installation or retrieval. Polyspace™ provides an innovative, cost effective solution at pipeline crossings where clearance is required. As this system becomes an integral part of the cable, additional problems associated with installing over a pre-laid ‘bridge or separator’ are negated. This is in addition to the obvious benefits of no pre-lay operations and the associated costs this would entail.
Polymat ™ Polymat™ is a useful, ROV installable mat that provides general protection and stabilisation to cables and pipelines. The mat is sized and weighted to suit client requirements and ROV capabilities. Polymat™ is moulded from Trelleborg CRP’s “marine grade” polyurethane material (see page 16). It also incorporates a barytes infill that provides additional ballast to aid product stability on the seabed. Although the size of each Polymat™ can be tailored to suit client requirements typical deep water applications require mats that are circa 2.3m long x 1.5m wide x 25mm thick.
Spiraduct+ The Spiraduct+ system is designed to provide an additional protective layer for impact and abrasion protection for subsea cables, umbilicals and other tubulars. Spiraduct+ consists of discrete cylindrical sections manufactured in marine grade rubber and cut to form a spiral wrap. Installation simply involves opening the helix and winding it around the cable. This makes Spiraduct+ particularly suited to installation by diver. Spiraduct+ is also suited to providing temporary cable protection; for example, preventing abrasion at the cableship sheave during a cable repair. It can also be utilised for short runs of cable liable to impact or abrasion e.g. ROV or plough control umbilicals. Spirawrap is suitable for small diameter cables up to 100mm OD and where tight bend radii of up to 0.5m can be expected.
Polymat™ is moulded with grooves on one side to allow the mat to flex and closely fit the profile of the cable or pipeline.
For ease of handling, holes are moulded along the edges of each Polymat™ to allow attachment for pickup ropes etc.

With extensive stock and over 30 years of banding experience gained in harsh offshore environments, Trelleborg CRP offer an augmented service, combining material knowledge with worldwide inventory and distribution expertise providing a cost-effective and convenient service.
Alloy 625 Alloy 625 is a nickel-chromium alloy containing molybdenum. Exhibiting high tensile strength and excellent anticorrosion properties, it is especially resistant to crevice corrosion. The tensile properties of Alloy 625 enable it to be used in high load applications Whether in marine, subsea or chemical environments.
Stainless Steel Stainless Steel (316) banding is suitable for medium duty installations, typically within the automotive, food and pharmaceutical industries or medium term installations in seawater.
Carbon Steel Carbon steel is a cost - effective alternative for use in non-corrosive environments or temporary applications. Carbon Steel offers high tensile strength and is often used within the packaging industry or as a temporary installation aid in a Subsea or Marine environment.
Titanium
Non-Metallic Banding
Titanium combines an outstanding strength to weight ratio with excellent anti-corrosion properties, making it ideally suited to small diameter yet heavy duty banding applications. Titanium exhibits exceptional resistance to corrosive attack from salt water, acids, alkalis and industrial chemicals.
For less arduous applications, Trelleborg CRP also supply a non-metallic strapping system, which combines a separate strap and low profile seal.
Kevlar® For extreme high load conditions Trelleborg CRP offers a wide range of Kevlar strapping systems with nominal breaking loads of between 5Te and 12.5Te. Each strap is precisely manufactured to length and supplied complete with a high strength tensioning assembly. Metallic tensioning assemblies are supplied in alternative metallic grades to suit system design life.
Both band and seal are manufactured from a glass filled Nylon 11 material which exhibits excellent resistance in the most corrosive environments, in particular seawater. The seal has been designed with a smooth low profile, minimising the risk of snagging on a third party object. The band is efficiently installed using either manual or pneumatic tooling.
Installation Tooling To simplify the banding operation, Trelleborg CRP offers a range of manual and semi-automatic banding tools available for hire. All Trelleborg CRP tools are meticulously maintained and serviced to ensure they will function reliably, even in the most difficult conditions. To aid service turn-around a comprehensive stock of spares are held on-site and these are backed up by a detailed database that tracks the current location of each tool - to ensure our tools are available wherever and whenever they are required.

Materials Technology
The Uraduct range, inclusive of VIV suppression mouldings and Polymat™, is manufactured using a wide range of polyurethane elastomer compounds with a variety of mechanical and physical properties to suit different applications and environments. ®
14
These compounds have a proven track record in the marine environment and have been subject to extensive research, testing and trials to ensure optimum performance -Trelleborg CRP is Proven to Perform.
Marine grade polyurethane
High density polyurethane
This is the industry standard material for Uraduct® offering excellent abrasion and mechanical protection for a wide range of applications in a cost-effective manner. This material has a specific gravity of 1.18g/cm 3 and therefore does not add any significant weight to the full installation once immersed.
Where additional stability and ballast is required, specially formulated high density polyurethane is available. This material has a specific gravity of 2.3g/cm3 and offers an equivalent in-water weight to concrete. Uraduct® manufactured in this grade of polyurethane can be utilised where cables will be exposed to strong seabed currents and additional weight and stability will be beneficial.

Super heavy weight Uraduct®
Buoyant/Thermal grade
In addition to the individual polyurethane compounds mentioned, Trelleborg CRP has developed a super heavyweight Uraduct® that combines the excellent abrasion resistant qualities of the high abrasion resistant polyurethane with the added weight of lead.
For applications where additional buoyancy is required, a buoyant grade of polyurethane is available with a SG of approximately 0.7g/cm3. Uraduct® manufactured from this material has been used to provide impact and abrasion protection on cable pull-in operations to reduce the pulling forces required by providing a reduced combined Uraduct® and cable weight per metre. This elastomer also exhibits thermal insulation properties where hydrocarbon temperatures need to be maintained on rigid and flexible pipelines.
Lead inserts are encapsulated in each Uraduct® half-shell during the moulding process. This is done in such a way as to maintain the flexibility of standard Uraduct®. The ratio of lead to polyurethane can be varied to give an average SG of 3g/cm3 and above. This product is ideal for stabilising submarine fibre optic cables at crossings, for shore landings, and for touch down ballast of umbilicals or flexible risers, and in general for areas where strong seabed currents are expected. The added stability due to the weight and high abrasion characteristics of the polyurethane delivers a Uraduct® system that can be applied in the most demanding locations.
Super abrasion resistant polyurethane Where the installation requirements call for a very high level of abrasion resistance, dynamic contact with coral or rocky outcrops for example, very high abrasion resistant polyurethane is available. With a similar SG to standard grade material of 1.15g/cm3, this polyurethane can be utilised, not only to provide excellent impact protection, but also to extend the life of the core product in areas where specific abrasion problems have been recognised.
Special grades and colours Generally, standard grade polyurethane is supplied in orange, high density in mustard, super heavyweight in black and buoyant/thermal grade in yellow. Trelleborg CRP are also constantly researching and developing special polyurethanes to satisfy the evolving requirements of our customers. For specific projects, Uraduct® can be manufactured using a variety of harder or softer grades of polyurethane to suit.
