Operating what is probably the most advanced buoyancy manufacturing plant in the industry, Balmoral provides high quality, consistent modules which result in low water absorption and compression throughout their service life. 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.
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.
Deepwater projects require modules and clamps to be designed for operating depths in excess of 3000msw where substantially larger modules and extreme clamping loads are demanded.
BOE 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.
