Pipeline Construction

A sunny day and the welders are down in the trenches connecting another section of 24 inch pipe to the pipeline as they work their way from the pullback bore pipe to the wetland area.

This year's warm, dry spring provided a dry section of trench for the welders to work in.

Almost as soon as one excavator digs a trench, another excavator is ready to lay a section of pipeline in it.

The excavators are busy digging and moving pipe.

Pipeline Construction

The welding of sections of 24 inch pipe completed and passed the X-ray inspection.

The completed sections of welded pipe were moved out of the welding area to allow the excavators to start digging the trenches to bury the pipe in.

While the trenches are being done, another crew will sandblast and coat the welded joints.

The sections of 24 inch pipe are strung out in the right-of-way through our woods and ready for welding.

The welding trucks are lined up and waiting for the finial positioning of the pipe.

A walk around the pond

The day was sunny, but cool, and I was checking on the two geese staying at our pond. As usual, I had my camera ready to photograph the many changes of springtime. The first photo will be a guessing game with the answer at the end.

What is it? Click on image to see the detail of this springtime visitor.

At the shallow end of the pond a large bullfrog (Rana catesbeiana) was enjoying the sun while trying to stay warm.

At the far end of the pond, near the woods, the wild blueberry bush (Vaccinium corymbosum) was in full bloom.

Answer to "What is it?" ... A dandelion (Taraxacum officinale) seed head.

Spring Wildflowers

While walking along the pipeline right-of-way, near our wetland area, I found some Wild Geranium (Geranium maculatum) starting to bloom.

The flower starting to open.

The small, 1 to 1.5 inch flowers will range in color from rose-purple to violet-purple.

The tiny, 1/4 inch, Mouse-ear Chickweed (Cerastium fontanum) flower is easy to miss.

Flowers consist of 5 white petals that are deeply lobed, giving the appearance of 10 petals.

Pipeline Construction

The 1/2 mile long directional drilling project on the Wilmot Pipeline completed the pipeline pull back yesterday and only a few feet of pipe extends out of the ground. With the pull back complete, crews now work on connecting the pull back section with other sections of the pipeline.

Excavators were busy removing loose dirt from around the pull back pipe to reach solid ground for the placement of the next section of pipeline.

As one team start to lay out pipe for the next section of pipeline, another team works on the layout of complex pipe bending to tie the two sections together.

Pipeline Construction

The morning was sunny and bright as the 24 inch pipeline started its 1/2 mile journey through the bore hole. A row of three excavators lifted the pipeline into position for its entrance into the bore hole.

As the pipeline is pulled into the bore hole it is coated with a bath of drilling mud to lubricate it.

It didn't take very long for the first two of four sections of pipeline to be pulled into the bore hole. While pipeline section number three was being welded onto the pull back pipeline, it was a good time to inspect the bore hole entrance.

Pipeline Construction

Today marks another milestone for the Wilmot Pipeline construction as the equipment is readied for the pulling of pipeline into the directional drilling bore hole.

A device called a "pull head" is moved into position for welding onto the first section of the pipeline. The pull head will be attached to drill pipe, that is already in the bore hole, and then pulled back through the bore hole.

Back at the bore hole, a reamer and swivel are attached to the drill pipe that runs through the bore hole.

An "Army" of excavators is required to lift and move the section of pipeline.
