15 Drilling Riser Buoyancy Drill Riser Buoyancy Drill Riser Buoyancy Modules (DRBM) reduce a drilling riser s net weight in water and ensure that the structure and drilling vessel are supported. Fitted around the length of the riser pipe, DRBMs improve the riser s buoyancy and protect it from service damage. Module densities provide uplift for riser in saltwater depths of up to 12,000 ft Low Density Syntactic Foam comprised of a combination of hollow composite microspheres and macrospheres to provide uplift Design includes recesses to accommodate fastening hardware and auxiliary lines of drill riser Tough exterior skin provides excellent abrasion and impact resistance to avoid damage in handling and installation 15 Drilling

16 Drilling Riser Buoyancy Ultra M.I.S. (Module Integrity System) Since DRBM s operate in the harshest of marine environments, Trelleborg developed the Ultra M.I.S. (Module Integrity System) safety system. The Ultra M.I.S. system provides a two-fold increase in mechanical strength, and buoyancy elements have the ability to accommodate nearly twice the deflection before sustaining damage when compared to a standard (non-m.i.s.) buoyancy element. Enhanced safety Ultra M.I.S. Increased mechanical strength and optimized uplift Low density syntactic foam Depth rates available to 12,000 ft 16 Drilling

17 Drilling Riser Buoyancy Buoyancy Repairs Trelleborg provides global repair services for damaged buoyancy modules.

20 Riser Ancillaries Riser Grommets Trelleborg s Riser Grommets are manufactured from custom molded composite materials typically used on drill risers such as polyurethane. Riser Grommets allow the buoyancy to provide added containment of auxiliary lines between existing line clamp bands within the existing buoyancy tunnels. Centralizing of lines Improved containment Does not add to external profile 20 Drilling

21 Riser Ancillaries Riser Pin and Box Protection Trelleborg s Polykap Protectors are designed to provide critical protection to the drill riser during transportation, storage and deployment.

25 Crushable Foam Wrap Crushable Foam Wrap 25 Downhole

26 Crushable Foam Wrap Crushable Foam Wrap Crushable Foam Wrap is designed to be installed around the inner drill casing which is then immersed within the annulus fluid. As the pressure of the annulus fluid increases, the CFW will collapse at a pre-determined pressure and temperature combination, allowing expansion of the annulus fluid and dispersing any potentially destructive pressure increases. CFW is placed in the trapped annulus and allows the free flow of liquid Honeycomb microstructure allows collapse of the foam to take place and remain intact Collapses after the maximum operating temperature is reached Reduces risk of cracking 26 Downhole

28 Bend Control Solutions Bend Restrictors Bend restrictors are used to protect flexible pipelines from overbending and buckling during their installation or operation phase where static loads are generated. The system comprises a number of interlocking elements that articulate in 3 dimensions when subjected to external loads. At a designed radius the elements mechanically lock to form a semi rigid curved structure that will not move further. A split design allows installation of the restrictor after pipe termination Ease of installation onshore and offshore Light weight in water, reducing the loading on the pipe Increased durability 28 Subsea

29 Bend Control Solutions Bend Stiffeners Bend stiffeners acquired their name because the conical shape gradually increases the overall stiffness of the tubular in order to prevent over bending at the termination point. Manufactured from elastomeric material, a bend stiffener is suited to the constant wave and current induced motion of dynamic installations but can also be used for static applications. Added local stiffness to the umbilical or flowline Limits bending stresses and curvature Prevents structure damage from overbending Reduces structure fatigue 29 Subsea

30 Buoyancy Buckling Mitigation Buoyancy Buckling arises when flow lines move from their original installed position on the seabed. The movements can cause high compression forces, bending moments, and shear forces that affect the pipeline integrity. Adding discrete elements of buoyancy to the pipeline can help to mitigate this buckling. Prevents the pipeline burying or digging in the seabed Reduces friction between the seabed and pipe Reduces the loads at end connections improving the fatigue life Helps to prevent over rotation 30 Subsea

31 Buoyancy Distributed Buoyancy Modules Distributed Buoyancy Modules (DBMs) are typically used between a subsea structure and a surface vessel or platform. The clamping solution allows the DBMs to be fitted at any point along the length of the pipeline. The two main functions of the DBMs are to provide uplift and maintain location along the riser. Reduces top tension loads Maintain project specific riser configuration Fast, efficient and safe offshore installation procedure Compliant systems aimed at encapsulating large flowline tolerances and expansions or contractions Industry qualified materials and geometry 31 Subsea

32 Buoyancy Installation Buoyancy When installing heavy, large diameter pipelines offshore especially in deepwater, the tensions generated on the installation vessel can be extremely high. To reduce the weight of the pipeline during installation, discrete buoyancy modules can be strapped to the pipeline on board the vessel or in the case of a shore pull, installed on land. Wide range of depth ratings from shallow to deep sea Available in an ROV releasable system 32 Subsea

33 Buoyancy Riser Towers Riser Tower Buoyancy is supplied at specific locations or along the full length of the riser.

91 Buoyancy Distributed Buoyancy Modules Distributed Buoyancy Modules (DBMs) are typically used between a subsea structure and a surface vessel or platform. The clamping solution allows the DBMs to be fitted at any point along the length of the pipeline. The two main functions of the DBMs are to provide uplift and maintain location along the riser. Reduces top tension loads Maintain project specific riser configuration Fast, efficient and safe offshore installation procedure Compliant systems aimed at encapsulating large flowline tolerances and expansions or contractions Industry qualified materials and geometry 91 Renewables

92 Cable & Flowline Protection J-Tube Seals A J-Tube seal is designed to act as a seal and as a corrosion inhibitor between an umbilical/flexible riser and a J-Tube or I-Tube on offshore platforms. Two designs of J-Tube seals are available. The diverless design is pre-installed onto the cable prior to deployment and features a polyurethane lined compliant clamp to prevent contact of metallic components with the umbilical/flowline as one unit. The diver installed version is installed after deployment and is designed for retrofit applications. Features a fully split design Enables installation after termination of the umbilical or flowline Reduces the possibility of damage to the umbilical outer layer 92 Renewables

98 Bend Control Solutions Bend Restrictors Bend restrictors are used to protect flexible pipelines from overbending and buckling during their installation or operation phase where static loads are generated. The system comprises a number of interlocking elements that articulate in 3 dimensions when subjected to external loads. At a designed radius the elements mechanically lock to form a semi rigid curved structure that will not move further. A split design allows installation of the restrictor after pipe termination Ease of installation onshore and offshore Light weight in water, reducing the loading on the pipe Increased durability 98 Renewables

99 Bend Control Solutions Bend Stiffeners Bend stiffeners acquired their name because the conical shape gradually increases the overall stiffness of the tubular in order to prevent over bending at the termination point. Manufactured from elastomeric material, a bend stiffener is suited to the constant wave and current induced motion of dynamic installations but can also be used for static applications. Added local stiffness to the umbilical or flowline Limits bending stresses and curvature Prevents structure damage from overbending Reduces structure fatigue 99 Renewables
