Among all the fields that GN Solids Control
is professional in, HDD Rig’s mud recycling systems or
units are one of the most important and specialist one. Since its establishment
years ago, GN has been providing large HDD contractors in and out of China.
Now, like the largest HDD project contractor in China, CPP, is a long-term
client of GN Solids Control, at beginning of this year, CPP signed order to GN
Solids Control, with 8 sets of 500 GPM mud recycling system, with the highest
Each year, GN will produce tens of such
systems, mostly for clients from market abroad, like Australia, Thailand,
Singapore, India, Kuwait, and some countries in Africa. GN has a series of
mature products of mud recycling systems for HDD, with most popular treating
capacity as 200 GPM, 350 GPM and 500 GPM. Of those, 500 GPM systems are most
frequently used in China.
For the same capacity systems, 500 GPM, GN
has different configurations for option, both economic configuration and
premium configuration available.
The most difference between the economic
configuration and premium configuration is the treating equipments. This time,
for the order of CPP, it is the premium configuration, with shale shaker, desander cones with under shaker, desilter cones with under
shaker and 2 sets of decanter centrifuges. For a normally economic
configuration, there is some times a mud cleaner which is combined by a mud shale shaker, a desander and a
desilter, and in most cases there is no centrifuge. And when more treating
equipments are used, there will be larger surface for them, accordingly, the
storage capacity is enlarged.
In case of Piling work or TBM projects, the
mud system, or so called slurry plant is simpler. Normally the slurry for such
projects is not requested to be treated so fine, so there is no need for
desilter cones, only to choose enough desander cones according to the desired
treating capacity. And for Piling mud systems, there is no mixing facilities.
