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.


Welcome to visit GN Solids America in Houton to check our stocked solids control equipments.

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.
