This standardized approach enables faster installation, easier commissioning, and consistent performance across multiple drilling rigs.

At the heart of each package is a GN decanter centrifuge designed specifically for drilling fluid solids control. The centrifuge efficiently removes low-gravity solids from drilling mud, helping to stabilize fluid properties, improve rate of penetration, and reduce drilling-related risks. By maintaining cleaner drilling fluids, operators can extend the life of drilling tools and minimize non-productive time during offshore operations.

To accommodate variable drilling conditions, the centrifuges are equipped with variable frequency drive (VFD) systems, allowing operators to fine-tune bowl speed and differential speed in real time. This flexibility is essential in offshore drilling, where formation changes and drilling fluid characteristics can shift rapidly. The ability to adjust separation parameters helps ensure optimal performance throughout different drilling phases.

Durability is a key consideration for offshore equipment. GN centrifuges are built with enhanced wear protection on critical components, including hardened screw flights and abrasion-resistant feed zones. These design features significantly reduce maintenance requirements and extend service intervals, which is especially valuable offshore where maintenance access is limited and operational downtime is costly.
