Responsible for mud.Bottom dumping hopper with the movable Bottom Door . Dedicated to the trailing Suction Hopper Dredger
Bottom door means having self-propelled bunkering functional and non-self-propelled Dredger carrying ship or dredged material (commonly known as mud Barge ) Disposing dredged material dedicated facilities. Bottom door are relative terms, it is a dedicated loading bay dredged material (commonly known as the hopper) dump device.
Photo of our Bottom Door:
The form and amount of Bottom door is generally based on the size of its hopper and the hopper loads the specific circumstances of the particle size, viscosity, specific gravity and waters the ship construction and design.
Bottom door are generally installed in the bottom of the hull of a vessel can be opened and closed through human or mechanical (electrical, hydraulic). Different types of Bottom door its control, opening and closing time (speed), the degree of opening of the open, dredged material by ability has its own characteristics.
A. General
High accuracy, fully welded, painted construction can be used for trailing suction hopper dredger.
Load pipe plays an important role, transport the dredge mixture to the hopper, then transmit through the load box pipe, to other position.
Dredger Structure pipe with high quality including Loading Box, Jet Pipe , Suction Pipe, spud, riser pipe, flange pipes etc.
B. Construction and procedure
The construction is to be built according to the drawing with rules of good workmanship.
With wear plate welded in inlet tube to ensure the long service life
According to the different function, normally load pipe has 1 inlet tube or 2 inlet tubes
On main pipe part, there will be several exit holes.
C. Materials
All fabricated steelwork used in the construction of the load box pipes will be to manufacturing standard of normal or classification society.
All materials proposed will be selected to comply with the latest Health and Safety Rules.
Paint systems for hull protection will be of the highest quality (Hempel, Inter, Sigma, Jotun)
D. Welding
All welding will be performed in accordance with drawing and order and UniSite experience and all welding will be continuous and full penetration.
E. Workmanship
The workmanship have good marine practice. Care are taken to ensure fair lines, smooth surfaces and neat welding.

Coalbed methane (CBM) specialized downhole screw pump
Screw Pump Coalbed Methane using condition
      For the high rank CBM longer life span, the coalbed methane output maximization, straight to the ground drive screw pump in high rank CBM production parameters optimized research. Considering high rank CBM system and well, pump for line of coordination between the actual constraints.
Screw Pump System Brief Introduction
       Screw pupmp system consists of Surface Drive Device, Downhole screw pump, Electrical Control Panel and Matching Tools.
       Screw pump has been widely used in oil fields at home and abroad and plays an important role in oil production. There is a trend to replace the large heavy pumping units in shallow well and middle-deep well.
Applicable Oil Condition
       The screw pump can be used for low viscosity crude oil, also for heavy oil, high freezing point oil, high wax oil, high sand oil and high gas oil. It has advantages of one-time low investment, high oil production efficiency, low energy consumption, simple structure, and easy operation, installation, and maintenance.
Advantages:
It has advantages of one-time low investment, high oil production efficiency, low energy consumption, simple structure, and easy operation, installation, and maintenance.
