Boreline Installation using a Mobile Crane
In this particular project, two submersible pumps had to be installed quickly and efficiently for a temporary (3 week) dewatering job and Boreline was the obvious choice.
Site restrictions did not allow the Boreline to be installed horizontally, ie. where it is laid on the ground, tied to a vehicle and lowered into the well.
Instead, a mobile crane was deployed at the wells and this would be used to install the pumps and Boreline to the required depth.
Below are some pictures to indicate the procedure when installing Boreline vertically. An advantage is that mobile cranes are readily available and are sometimes needed to lift heavy pumps into position. But in this case, when the drop pipe is Boreline, the project becomes easier, simpler and much safer.
The pump and power cable have already been attached to the Boreline along the entire length. The lengths were then folded and packed onto the trailer, for transport to the well.
Arriving on site
Due to its lightweight and roll-flat nature, Boreline could be delivered to site on a trailer attached to a standard pick-up instead of on a large, low-bed truck.
A heavy-duty clamp is attached to the hose and used to lift the pump into position. This clamp consists of two sections of channel iron that squeeze and grip the Boreline. In this way the pump and pipe can be raised and lowered.
Lowering the pump and Boreline
The Boreline and pump are simply raised, positioned and lowered straight into the well. There is no need for screwing sections or attaching the power cable as this was completed off-site. (During subsequent retrievals and installations, the power cable will not have to be untied from the Boreline, as they remain joined together.)
The heavy-duty clamp will come to rest on the well casing while the other clamp is attached to the hose.
Heavy Duty clamps in operation
The second clamp is lifted, raising the first clamp at the well, which is then removed. The next section on Boreline is lowered with the second clamp coming to rest again on the well casing.
Releasing the clamp
This operating will continue until the pump is set at the required depth and the base plate comes to rest on the well casing at the surface.
The pump is installed in one continuous length of Boreline. There are no joints. There are no welds. It is just one continuous length from the pump to the surface.
When viewing a video clip of this installation, one can get a very good idea of the effortless, simple and straightforward, quick and easy, secure and safe method of installing any submersible pump on Boreline. It just makes sense.
Both pumps are in position and are plumbed and connected at the surface. The dewatering process began within a couple of hours and ran continuously until the project was completed.
