Operating what is thought to be the most advanced buoyancy manufacturing plant in the industry, Balmoral provides high quality, consistent modules which result in low water absorption and compression throughout deployment and service. Balmoral distributed buoyancy modules are fully accredited by Bureau Veritas to API 17L standards. Dynamic applications normally involve an offshore floating production facility or terminal connected to another floating facility or fixed structure. Flexible pipe and umbilicals require the use of buoyancy modules to reduce topside or tension loads and assist in achieving particular configurations which include steep, lazy, W-wave and pliant. Balmoral 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 flexible. This recess also accommodates bending of the riser during deployment and service. The internal clamping system is fixed to the pipe and the two half modules are fastened around the clamp. Deepwater projects require modules and clamps to be designed specifically for operating at depths in excess of 3000msw where substantially larger modules and extreme clamping loads are demanded. Balmoral has been at the forefront of significant R&D efforts to meet this challenge and has developed a number of solutions for deep and ultra-deepwater environments. . distributed buoyancy, distributed riser buoyancy, clamp, high performance clamp, standard clamp, integral clamp, API17L, API 17L, piggyback buoyancy, VIV strake buoyancy, modules, flexible, catenary, steel, dynamic, flowline
Drill riser buoyancy provides uplift while reducing the submerged weight of the riser joints. This helps to minimise top tension and prevent stress in the riser as well as reducing loadings during deployment and retrieval of the blow-out preventer (BOP) stack. Drilling risers extend from the BOP to the drilling vessel with their primary function being the provision of fluid communications between the well and the vessel while supporting choke, kill and auxiliary lines. Balmoral consistently manufactures high quality modules while its in-house hyperbaric test centre offers test facilities to 7000msw equivalent. Balmoral drilling riser buoyancy modules are fitted around the riser with moulded apertures accommodating auxiliary lines and riser clamps. The vertical lift of the syntactic modules is transferred to the riser by a thrust collar fitted to the riser pipe below the upper coupling. A matching collar is normally installed at the lower end of the assembly to facilitate the transfer of the module weight during handling.

Balmoral low drag VIV (LDV) suppression buoyancy is a result of the company’s continuous innovation drive to provide clients with industry-leading technology to help reduce offshore operational costs. DuraFloat LDV (patent pending) technology integrates vortex induced vibration (VIV) suppression and drag reduction into drill riser buoyancy modules to increase rig efficiency without compromising on safety or structural integrity. The system minimises vessel down time, directly relating to significant cost savings. The system is designed to provide optimum uplift values while offering up to 75% VIV suppression efficiencies which dramatically improve riser motion and drag in onerous subsea current environments compared to traditional drill riser buoyancy. The revolutionary hex design eliminates the need for ancillary suppression equipment and helps reduce time-consuming activities when running and removing drill stacks. Additionally, it is recognised that reduced riser motion due to VIV suppression dramatically improves the fatigue performance of subsea equipment resulting in further cost savings by extending the service life of wellhead and conductor/casing equipment. Three distinct products are available which utilise the LDV design, each tailored to provide maximum performance benefit. durafloat, duraguard, ldv buoyancy
