GN exported a drilling cuttings drying system to Europe. The drilling waste management system is used to treat oil based drilling cuttings collected from oil drilling rig. Customs move drilling cuttings from offshore drilling rig to their yard for treatment. GN sent engineers to help them for commissioning and training their people for system running. The performance is good, customer is satisfied.

Equipment included in the drying system to Europe offshore rig
1) Vertical cuttings dryer: Model GNCD930C-VFD, Qty 1 each
Customer choose variable speed control panel for the dryer. The speed can be adjusted from 0~900rpm, while G force can be adjusted to max. 420G. Customer can choose the suitable speed per job site condition.

2) Decanter centrifuge, model GNLW363BG-VFD, Qty 1 each
It is a variable frequency control decanter centrifuge, with positive pressurized control panel for changing speed.

This decanter centrifuge is used to separate the solids from the liquid discharged from the vertical cuttings dryer. After separation by the GNLW363BG-VFD decanter centrifuge, the oil or water recycled from cuttings dryer can be returned to the active drilling mud system for reuse.

3) Mud tank skid for mounting above solids control equipment.

4) Screw conveyor ( Augers) for feeding the vertical cuttings dryer with the drilling waste and also for transporting the drilling cuttings discharged from the decanter centrifuge and the vertical cuttings dryer.

Below is the raw material comes from rig site. It is mixture of oil, cuttings and drill mud.

After treatment of GN drying system, the OOC on cuttings can be reduced to less than 4%.

Below is the solid phase separated from GN drying system.

As you can see from blow picture, after separation, the liquid is very dry and difficult for decanter centrifuge to treat. In order to make it flowable and possible for centrifuge treatment, customer dilute it and to further separate the fine solids above 2~5 microns.

GN Solids Control Drilling Cuttings drying system is popular around the world from Asia to Europe , and from America to Russia.
