Recently 2 sets of offshore drilling mud cleaner are ready for shipment, the difference of the offshore used mud cleaner with onshore drilling mud cleaner is the lifting point and explosion proof vibration and starter. The lifting pad system conforms to DNV 2.7-1 or CCS lifting certificate to meet for offshore drilling. We can make customized design equipments according to different requirements.


The mud cleaner equipped with 3 ea of 10 inch desander cone and 16 ea of 4 inch desilter cone, all of the hydrocyclones are made of 100% composite material for longer working life, especially when the solids content is very high, we will use metal cover outside the polyurethane material cone in case that the hydrocyclone will be easily deformed and damaged. 2 units of 1.72KW vibration motor from Italy Oli or US Martin brand are used to drive the bottom drying shaker. The lifting frame with offshore approved lifting pad is designed for convenient lifting the equipment from land to offshore rig. We can provide different explosion proof standard motor and starter based on different requirement.


The mud cleaner with a 4 panel screen bottom shale shaker to recovery more useful drilling fluids. All of the screens are composite material frame shaker screen with stainless steel 316 wire mesh, we use 3 layers of wire mesh for all the API mesh over API60, which has been widely used in different countries for oil drilling rig for treatment of different types drilling fluids, the working life is from 300 to 700 hours.
Except for mud cleaner, GN solids control also produce other solids control equipments such as shale shaker (both linear motion shale shaker and dual motion shale shaker), desander, desilter, decanter centrifuge, centrifugal pump, mud gas separator, vacuum degasser, mud agitator, mud gun and drilling waste management equipments.

Recently 2 package of tandem shale shaker are shipped to India client, we have finished the necessary inspection before delivery, water test and mud test under the required API mesh size.


The 2 units of single shale shaker are installed on one oilfield 3 runners skid as tandem shale shaker for convenient shipment and operation. 3 pcs of pre-tensioned durable composite material shaker screens are installed on the shale shaker, the deck bottom are made of stainless steel for better anti corrosion. The shaker deck, vibration beam and all the vibration and non vibration components are all made of stainless steel. The shaker skid are made of structure steel for better strength. The vibration motor and starter including the cables, cable glands are all DGMS approved explosion proof products, which can meet the user’s requirement in explosion proof standard.


The shale shaker is designed to treat both water based drilling fluids and oil based drilling fluids, the operation temperature is -5℃ ~+55℃. We can produce shaker screens comply with API RP13C standard, the API mesh size is from API 20 to API 300 based on client’s requirement. The wire mesh material is made of SS316L for longer working life, and 4 corner pre-tensioned before heating press process will increase the working life of the shaker screens.
The shale shaker is most important solids control equipment and the first phase cleaning equipment for a solids control system, a better performance shale shaker can reduce the drilling waste volume, so that the drilling waste treatment cost will be reduced, and it can recovery more useful drilling fluids for the drilling rig, reduce the burden of next step cleaning equipment like desander, desilter, mud cleaner, degasser and centrifuge.
If you need solids control equipments and drilling waste management system, pls contact with GN solids control.

Recently GN solids control shipped one batch of telescopic skid vertical cuttings dryer and decanter centrifuge to an International oilfield service company. This is their repeat order, this client have over 30 units decanter centrifuges and 10 units of vertical cuttings dryer at their rig site for drilling waste management project. Especially in the tough period this year, the economy is going down, oil prices are falling, demand for petroleum products is decreasing, and the oil industry is in a slump, we got the continuous support from our old clients, their trust and repeat order help us a lot, and GN always try to supply the best quality, best delivery time, best after-sales service and spare parts support and the most economic solution. We are growing up together with our customers during the past 10 years.


We have standard design of drilling waste management system package GNCM-40A, which is widely used for oil based drilling cuttings treatment in the world, it consists of vertical cuttings dryer with flushing pump ( screw pump), VFD decanter centrifuge with feeding pump ( screw pump or submersible slurry pump), intermediate tank to receive the fluids discharged from vertical G dryer, telescopic skid for vertical G dryer, telescopic skid for decanter centrifuge, pipelines, tank accessories and tank skid, all of the items are installed on one package for convenient transportation, the design treating capacity is 40 m3/h. We also provide customized design as per client’s requirement.


This customer need the decanter centrifuge and vertical cuttings dryer one 2 separate telescopic skid, by this way, they can use the equipments flexible for different rigs, and they can make the rest accessories locally to save cost. During transportation, the skid height will be down to meet the transportation limit, and during operation, they will be lifted up for archive better separation result.

Recently GN solids control shipped one batch of shale shaker and decanter centrifuge for an international environmental protection company. The equipments model number is as below:

  1. Shale Shaker: GNZS594-HB, the 4 panel shaker screens with dimension 585x1165mm, which is made of composite material frame durable shaker screens. The vibration motor and starter are purchased from USA local company to meet the local explosion proof standard. The shale shaker is to separate coarse solids from the slurry/ sludge/ drilling fluids/ oil sludge.
  2. Mud Cleaner: GNZJ594-2S12N, the bottom shale shaker is a 4 panel shaker screen which is same with GNZS594-HB, combined with 2ea 10 inch desander cone and 12ea of 4 inch desilter cone. The mud cleaner is used after shale shaker, the desander cone separation cut point is 45 microns, the desilter cone cut point is 25 microns. Over 80% of the solids bigger than 25 microns will be separated out. If much finer solids still need to separate, decanter centrifuge can be used.
  3. Decanter Centrifuge: GNLW553-VFD, the separation cut point is 2~5 microns. The centrifuge bowl diameter is 22 inch, the bowl length is 71 inch (1800mm), the max G force is 2719G and the max speed is 3000rpm. The max gearbox torque is 12000 N.M. and gearbox ratio is 35:1. The differential speed is 0~45 rpm. And designed treating capacity is 500gpm. The decanter centrifuge is drived by VFD control panel, with world famous brand inverter of main motor, back drive motor and pump motor.
    The shale shaker, mud cleaner, decanter centrifuge are installed on the customized dimension mud tank, the discharged fluids dropped into the mud tank, the feeding pump ( centrifugal pump) transfer the treated fluids to desander cone and desilter cone, the clean fluids are transferred to decanter centrifuge by screw pump.
