GN Solids America Successfully Participated OTC 2025 in Houston NRG Center

GN Solids America successfully participate in Offshore Technology Conference (OTC) 2025 in Houston NRG Center last week.


The Offshore Technology Conference (OTC) serves as a central hub convening energy professionals from around the world to share ideas and innovations, discuss, debate, and build consensus around the most pressing topics facing the offshore energy sector.
As a professional manufaturer of solids control equipments, drilling waste management equipments, and advanced separation solutions, GN Solids America captivated attendees with its innovative technologies designed to enhance efficiency, sustainability, and cost-effectiveness in the oil, gas, and environmental sectors.


What equipments did GN Solids America showed at OTC 2025?
1. GNLW223D 9 inch Decanter Centrifuge: it has been widely used for diamond core drilling waste water treatment and fluids recycling, oil sludge treatment, tank cleaning, etc.applications. It Specially designed for small capacity, small footprint and fine solids separation.


2. GNSP-10B Sludge Vacuum Pump: it is a 100% air operated transfer pump used to transfer different materials such as oil sludge, drilling waste, contaminated soils and other solids in hazardous environments without electricity power requirement, especially suitable for electricity limited area. It can be also used as vacuum cleaner to pick up the splash waste from the rig floor, the movable design allow the vacuum pump to move easily. Except for GNSP-10B vacuum pump, we also have GNSP-20B and GNSP-40B vacuum pump for option with higher transfer flow.


3. Shale Shaker: High G force linear motion with 4pcs composite material frame shaker screens installed on the shale shaker, 2ea Martin brand vibration motors drived the shale shaker. GN produce shale shaker for various industries with different technical specifications, including 2 panel shale shaker, 3 panel shale shaker, 4 panel shale shaker, 5 panel shale shaker and 6 panel shale shaker.

GN Drilling Mud Decanter Centrifuge and Centrifugal Pumps for Offshore Drilling Company

Recently GN drilling mud decanter centrifuge and centrifugal pumps are shipping to offshore drilling company.


The drilling mud decanter centrifuge is equipped with offshore lifting skid, compared with the onshore drilling mud decanter centrifuge, the skid for offshore drilling is special designed for safety and convenient lifting for offshore purpose, but without DNV 2.7-1 lifting certificate. When DNV 2.7-1 lifting certificate for the lifting pad is required, the skid should be designed specially. The stainless steel cabinet positive pressurized VFD control panel is separately on the ground, with main motor, back drive motor and pump motor 3 VFD, which is from ABB, YASKAWA, etc. famous brand, the other like PLC and touch screen and other electrical conponents from Siemens and other famous brands. The decanter centrifuge bowl and the screw core shaft are made of duplex stainless steel SS2304 by centrifugal casting, which is superior to the performance of SS304 and SS316.The solids outlet and fluids distribution port is protected by replaceable hard alloy sleeve. The wear resistant and anti-skid bars welded inside the bowl can effectively reduce the wear of the bowl under operation. The screw main material is also duplex stainless steel 2304. The screw blade is protected by tungsten carbide tiles, which is replaceable hard alloy plate.
The centrifugal pump all the parts are interchangeable with international brand pump, so the client can source the parts easily. The pump casing made from hard ductile iron alloy, which increased abrasion resistant performance. The pump skid is special designed for client’s particular requirement.


Except for drilling mud decanter centrifuge and centrifugal pump, we also produce linear motion shale shaker, mud cleaner, desander, desilter, vacuum degasser, mud agitator, mud tank system, etc. solids control equipments for the onshore and offshore drilling. For more information, pls contact with GN solids control.

Drilling Mud Recycling Unit and Hydraulic Centrifuge for Overseas Client

Recently one set of 500 gpm mud recycling system for trenchless mud treatment and one set of diamond core drilling hydraulic drive solids removal unit for overseas client.
The 500 gpm mud recycling system consists of shale shaker, mud cleaner, desander feeding pump, desilter feeding pump, 20ft container size mud tank, 20ft container lifting frame, mud tank accessories and electric control system. It is a customized design 500gpm mud recycling system for our client, we also have standard 200gpm, 400gpm. 600gpm, 800gpm, 1000gpm mud recycling system for HDD mud cleaning, mixing, recycling.


The core drilling hydraulic centrifuge system is solids liquid separation of waste water for diamond core drilling. The features of the core drilling hydraulic centrifuge system including compact design, modular design, lightweight to meet the requirement for helicopter hoisting, can operate without electricity power supply. The technical configuration is as below:
1. GNLW223D-FHD hydraulic centrifuge
2. Feeding and discharge pump: 2X FHD pump
3. Treating capacity: 50~130L/Min
4. Separation cut point: 2~5 Microns
5. Driving method：Diesel + Hydraulic drive
6. Mud tank volume： 2m3
7. Total power consumption: 40KW
8. Mixing hopper
The treatment process is as below:


The mud is pumped into the sedimentation bin of the buffer tank, so that the large particle sedimentation. After that, the mud overflow to the slurry supply bin of the feeding tank, the pumped by the #1 slurry pump to the hydraulic centrifuge for ultrafine solids separation. If without the sedimentation process, one unit of mini shale shaker will be used to separate the coarse solids from the mud. The mud treated by the hydraulic centrifuge flows into discharge tank and transferred to drilling machine by No.2 transfer pump, the treated clean water can be reused to prepare for new drilling fluids and used by the core drilling for cost saving.

Vertical Cuttings Dryer and Centrifuge Unit for Africa Waste Management Company

Recently one set of vertical cuttings dryer package and one set of decanter centrifuge unit with screw conveyors are ready for shipment to Africa drilling waste management company. The technical configuration of the customized drilling cuttings treatment system is as below:


1. GNCD930G vertical cuttings dryer with separate skid, the flushing pump is installed on the skid for flushing the screen basket during operation, we have 250 microns, 350 microns and 500 microns opening screen basket for option for client’s different requirement. Additionally, soft starter, VFD control is available for the main motor drive.


2. GNLW363D-VFD decanter centrifuge with feeding pump installed on the separate telescopic skid, the VFD control panel is also installed on the skid for convenient operation. The whole package is suitable for standard container loading when the telescopic skid lowered to the lowest hole. During transportation, the guardrail and walkway, stair can be foldable and attached with the skid for convenient transportation.
3. The screw conveyor is used to collect the drilling cuttings from primary solids control shale shaker, then transfer to vertical cuttings dryer; it can be also used to collect the discharged solids from vertical cuttings dryer and transfer to skips. The user can make the auger support at site according to the installation requirement.
If the drilling cuttings have been storage in the waste pit at rig site, the sludge vacuum pump can be used to suck the drilling waste from waste pit and feeding to vertical cuttings dryer, the horizontal transfer distance is up to 500 ~1000 meters, it is specially suitable for transferring drilling waste with high solids content and high viscosity. Except for drilling waste, it has been widely used for oil sludge transfer, industrial waste transfer, sand transfer and industrial waste transfer.
