Last year the country's largest pipeline was attacked 39 times, causing oil spills of more than 100,000 barrels.

Roughly 400 miles of large pipelines fall into this category.

This equipment is used in larger pipelines where automatic metering devices would not be sufficiently reliable.

At the time of construction, it was the longest and largest offshore pipeline in the world.

The larger pipeline, which carries North Slope oil across the state, was completed in 1977.

It never has, though, because the large pipeline needed to get the water there was never built.

Sizes of air vessels may be up to hundreds of cubic meters on large pipelines.

To allow for increased production, construction started in October on a larger 10-inch pipeline.

However, as far as the supplier of this large pipeline is concerned, the information is very unclear.

There is a mention of weapons with him, but not an indication whether it was a standard or large pipeline.
