Title Balmoral Duraguard: Cable protection Description Duraguard was developed for the protection of subsea cables, flexible jumpers, flexible flowlines and riser touchdown zones although many other applications have been identified. Balmoral Duraguard provides a cost effective localised impact and abrasion protection system and is supplied as pairs of interlocking half shells secured around the core product using circumferential straps. It is manufactured in a range of polyurethane elastomer grades, depending on the specific operational conditions, and can be supplied in a wide range of diameters, wall thickness and lengths. Typical lengths are determined by the individual half shell weight and can vary from 500-2000mm. In addition to providing mechanical protection, Duraguard HD can be supplied in a highly ballasted form to enable its use as ballast or stabilising systems.

Title Bend restrictors Description Designed as interlocking elements, bend restrictors prevent over-bending at the interface between flexible flowlines, umbilicals and cables and rigid structures such as wellhead connections, J-tube exits, rigid pipe crossovers and PLET connections by mechanically locking up. They are normally used in static applications but, unlike bend stiffeners, only provide protection once the pipe has achieved the desired bend radius. Designed in accordance with API 17J Appendix B, BOE bend restrictors are manufactured in rigid structural polyurethane two piece units that are bolted together around the pipe.

Title Bend stiffeners Description Bend stiffeners are used to support flexible pipe, umbilicals and cables when connected to rigid structures or a floating production system where there is a requirement to control the minimum bend radius of the pipe. They are usually attached at either the topside or seabed connection. In dynamic applications bend stiffeners require to have sufficient fatigue resistance to control the in-service bend radii and sustain the cyclic loads to the end of the specified life whereas in static applications they protect against gross over-bending. Stiffeners are typically conically shaped polyurethane mouldings with a cylindrical bore that slips over the pipe, umbilical or cable. Balmoral bend stiffeners are designed in accordance with API 17J Appendix B using specifically formulated polyurethane materials and are engineered to suit specific operational parameters.

Title Dynamic buoyancy modules Description Flexible pipe and umbilicals require the use of buoyancy modules to reduce topside or tension loads to achieve particular configurations which include lazy, steep, pliant and W-wave. BOE distributed buoyancy modules generally consist of an internal clamping system and syntactic foam buoyancy elements. The buoyancy elements are supplied in two halves incorporating a moulded internal recess that is configured to transfer the forces from the buoyancy to the clamp and subsequently the riser. This recess also accommodates bending of the riser during service. The internal clamping system is fixed to the pipe and the two half modules are fastened around the clamp.

Title ROV/AUV buoyancy Description With advances in deepwater technology the need for remote intervention as part of the field installation has seen major increases in the number of deepwater remotely operated and autonomous underwater vehicles. As the complexity of these vehicles evolves the demand for lower density, high performance composites buoyancy systems has increased. This is an area where Balmoral has made significant technological advances. The use of conventional cast composite buoyancy packs still has many commercial benefits for large vehicles used for trenching of pipelines or submarine cables. However, for deep dive work class ROVs, operating beyond 2000msw, the performance benefits of Balmoral’s LDF series becomes significant.

Title Thermal insulation Description The Balmoral Supatherm insulation system is based on a thermoset epoxy resin syntactic foam, originally developed for the simultaneous provision of buoyancy and/or thermal insulation on flooded sealine bundles and hybrid riser towers where lifetime tolerance to hot/wet conditions at temperatures exceeding 90ºC in depths to 3000msw. This exceptional performance characteristic also makes Balmoral Supatherm ideal for other high temperature ‘flooded shell’ insulation systems. The material has an extremely high glass transition point (Tg), so that full mechanical support for the hollow glass microspheres is maintained to well beyond all anticipated service conditions. This outstanding mechanical support allows the use of much lower density glass microspheres than is feasible with any other insulation system. This, in turn, results in the achievement of outstandingly low k-values; far below those of any competing insulation system.
