Hydraulic Drive Mud Centrifuge and Cuttings Dryer for Asia Client

One unit of hydraulic drive mud centrifuge and vertical cuttings dryer are ready for shipment to Asia client.
Fully Hydraulic Decanter Centrifuge (GNLW363D-FHD)


GNLW363D-FHD centrifuge is fully hydraulic drive. The bowl speed and conveyor speed is adjustable within the permitted range. It can achieve independent, stepless and large range speed regulation for the bowl and conveying. The bowl speed and conveyor speed during working is showing on the screen.
GNLW363D-FHD centrifuge is mainly composed of rotating assembly, hydraulic drive system and inlet and outlet interface device
Unlike conventional electric driven VFD decanter centrifuge, this fully hydraulic drive decanter centrifuge features a cutting edge hydraulic drive system. The system drives both the conveyor and bowl from a hydraulic pump unit through two independent hydraulic oil circuits, enabling precise, independent, and infinitely variable adjustment of bowl speed and scroll differential speed—even during operation
Vertical Cuttings Dryer (GNCD930G)


GNCD930G vertical cuttings dryer, it is a core piece of equipment for drilling waste management. Primarily designed to treat drill cuttings discharged from shale shakers when drilling with oil based or synthetic based mud, the cuttings dryer utilizes high speed centrifugal force to effectively remove residual liquid from cuttings. The GNCD930G is engineered to achieve an Oil on Cuttings (OOC) level as low as 3%–5%, meeting stringent environmental standards while allowing valuable oil-based mud to be reclaimed and returned to the drilling system
This significant shipment to an Asian oilfield service company underscores GN Solids Control’s commitment to providing high-quality, reliable equipment for offshore drilling operations worldwide.
s a leading manufacturer with API certification, GN Solids Control continues to support the global oil and gas industry’s efforts toward more environmentally responsible operations by delivering advanced, high-performance solutions.

Solids Control equipments ready for delivery

One batch of solids control equipments are ready for delivery for our international client, this is the third time repeat order from the same client. The solids control equipments purchased is for their solids control service contract. The equipments list including:
1. Decanter centrifuge, GN solids control can produce both fixed speed decanter centrifuge and VFD decanter centrifuge, the most popular model is 14 inch bowl decanter centrifuge. It can be used for both solids control drilling fluids treatment and drilling waste treatment system.


2. Vertical cutting dryer, it can be used for oil based drilling cuttings treatment, after treatment, the oil on the cuttings could be reach below 5%.
3. Screw pump, we have fixed speed screw pump and variable speed screw pump, it can be used as decanter centrifuge feeding pump and vertical cuttings dryer flushing pump.


4. Screw conveyor, we have fixed speed screw conveyor and variable speed screw conveyor, it can be used to collect the drilling cuttings from solids control shale shaker, and transfer to vertical cuttings dryer feeding port.
5. Vacuum pump, it can be used to transfer drilling waste cuttings, also it can be used to collect spilled drilling waste from the rig platform.
6. High G drying shaker, it can be used to treat water based drilling cuttings, and it can be used to reduce the solids content from the drilling waste, so the treating capacity of the decanter centrifuge can be improved.
All equipment has undergone factory acceptance testing (FAT) and is packed in export-grade, weatherproof packaging to ensure safe ocean freight transit. Delivery is scheduled for next week, with a company technician available for remote or on-site commissioning assistance as part of the service contract agreement.

GN Containerized Oil Sludge Treatment Plant for Africa Client

GN Solids Control has successfully supplied a fully containerized oil sludge treatment system to an African client. This compact, skid-mounted plant is designed to treat oily waste from crude oil tank cleaning, refinery ponds, and drilling operations. The system enables the recovery of valuable oil, recycles water, and significantly reduces solid waste volume—all while meeting stringent environmental standards.
The entire plant is integrated into standard shipping containers, making it ideal for Africa’s infrastructure conditions where ease of transport, rapid deployment, and relocation between sites are critical. The modular design also allows future expansion and simplified maintenance.


The system consists of four core modules:
(1) Pre-Mixing Tank Module
The pre-mixing tank module is the first step in the treatment process. Raw oil sludge often has high viscosity, high solids content, and poor fluidity. This module heats, dilutes, and conditions the sludge to create a homogeneous slurry suitable for downstream separation.


(2) Shale shaker Module
After pre mixing, the sludge still contains large debris, stones, and coarse sand. If these particles enter the centrifuge directly, they will cause accelerated wear and reduce separation efficiency. The vibrating screen module removes these oversized solids as a protective step.
(3) Three Phase Decanter Centrifuge Module
Including three phase decanter centrifuge, its feeding pump, fluids catching tank and skid. This is the core separation unit of the entire plant. The three phase decanter centrifuge simultaneously separates oil, water, and solids from the conditioned sludge using high centrifugal force. It is particularly suitable for oily sludge with wide fluctuations in oil content and complex compositions.


(4) Chemical Dosing Module
Effective chemical treatment is essential for breaking emulsions and enhancing separation efficiency. The chemical dosing module automatically prepares and injects flocculants, coagulants, and demulsifiers into the process stream.

All of the equipments are installed as compact unit for offshore application, the skid and decanter centrifuge lifting pad is designed comply with DNV 2.7-1 standard.
The decanter centrifuge motor and VFD control panel is adopted with offshore applied explosion proof standard. The ambient temperature to be used is -20℃ to +55℃.The standard atmospheric pressure is 80 Kp to 110Kp, normal oxygen content 21%, it can be used with altitude <1000m, relative humidity less than 95%. One centrifuge is composed of main bowl assembly, power drive system, feeding and discharge device and electrical control system.


The decanter centrifuge is widely used in the solids control and drilling waste treatment project, it works to separate the solids phase from drilling fluids, remove the harmful fine drilling solids such as debris in the drilling mud, or recover weighting materials such as barite , etc. as to save the drilling fluids cost. The decanter centrifuge can be used for both onshore and offshore projects, but the electric motor, control panel including VFD control panel, cables standard are different.
GN solids control can produce 9 inch bowl centrifuge, 14 inch bowl centrifuge, 18 inch bowl centrifuge, 22 inch bowl centrifuge, 30 inch bowl centrifuge, each size decanter centrifuge provides 2 models as rated frequency and variable frequency drive. Except for 2 phase decanter centrifuge, we also produce three phase decanter centrifuge to separate oil, solids and water for oily waste water treatment.
