Buoyancy Repair Solutions
It is vital that repair and refurbishment is carried out by fully qualified teams that understand the materials, procedures and environments to which marine buoyancy is exposed. Balmoral benefits from many years’ design, manufacture and materials experience and has dedicated teams of repair personnel travelling the world on a regular basis.
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.
Balmoral 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.
