Mud cleaning system is two main parts, the storage mud tank on below and many machines serve as purify the drilling fluid, which get rid of the solid debris in drilling fluid. The mud tanks which store drilling fluid are divided into circulation tanks and store tanks. Circulation tanks as a part of the filter cycle, there are shale shaker, vacuum degasser, deserter, and desander and decanter centrifuge on the top of tank.

The 1st level of purification
the drilling mud pumped away from the rig and flow-down in the shale shaker. The allocation drilling fluid enter into the bottom of the drilling well under the foundation of the drilling pump and carry drilling debris return the ground, through the elevated tubes enter into the shale shaker, the larger solid debris in drilling fluid are filtered through screen

Desander with GNZS752 Series Mini Shale Shaker

The2nd level of purification
When drilling fluid have debris contain gas, The use of vacuum degasser remove the gas which in the drilling fluid and can recover the density of drilling fluid, calm the drilling fluid viscosity.

The 3rd level of purification
the drilling fluid is disposed by two levels, mud purification enters into the desander.  Through the desander feed into the liquid pump, the harmful sold phase which the diameter is above 40-60um is separated in desander.

The 4th level of purification
the drilling fluid is disposed by the three level purification enter into the desilter through the desilter feed into the liquid pump, the harmful sold phase which the diameter is above 15-40um is separated in desilter.

The 5th level of purification
The drilling is disposed by the four level purification enter into the decanter centrifuge through the centrifugal feed liquid pump, the small harmful sold phase particles are separated in decanter centrifugal.

Usually, all five purification is all working at the same time. If it works one equipment or several equipments, the parameters of the drilling fluid can all meet the work requirements; it can work in one equipment or in several equipments. After the purification, drilling fluid can re-use in the drilling cycle

As vessel travels from ocean to ocean , there will be marine organism; marine organisms stay under the bottom of the vessel.Now the scientist and environment protection  staffs already paid attention to the need to reset instruments and to remove the inevitable weed barnacles and other marine life that would encrust a glider during very long voyages.

Pollution damage to the marine environment means any direct or indirect introduction of substances or energy into the marine environment which results in deleterious effects such as harm to marine living resources hazards to human health hindrance to fishing and other legitimate activities at sea impairment of the useful quality of sea water and degradation of environmental quality.

A hull cleaning recycle system can be used to help with the cleaning and reclaiming .Together with the customer ,GN developed such trailer mounted cleaning system and already applied on the seaside to do the job.

Hull cleaning system

Hull cleaning system

Customer use this separation system for sea water and shellfish to prevent the hybrid or shellfish from different area. When the ship arrived the port, they use one type scratcher to collect the shellfish stuck on the bottom of ship, and transfer the mixer of sea water and shellfish to the separation system. After treatment by the shale shaker and desilter unit, the shellfish could be removed from, water get back to the sea. Always the size of shellfish is not so small, therefore in the system there are only shaker, desander and desilter.

Trailer mounted system

Trailer mounted system


Trailer mounted sludge separation system is movable easily from one site to another, greatly increased the working efficience. This unit system structure simple only involving 2 stages solids control equipment.
