Give an explanation to the following purposes of the pipeline system.

Example: Moving is gas progresses from the gas field to gas processing plants and from there to the market.

· Gathering is …

· Transporting is …

· Moving is …

· Distributing is …

· Gathering system is …

Here is the diagram of Russian pipeline gathering system. Use the above-mentioned terms and give a short explanation to each element of the pipeline system. (Note the differences).

You are going to learn some vocabulary to help you understand the text. Study the following dictionary entries, paying attention to specific term definitions. Match the term with the appropriate meaning.

1.	disrupt (v)	A.	afford opportunity or possibility for
2.	install (v)	B.	go beyond the limits of
3.	prevent (v)	C.	interrupt the progress, movement or procedure of
4.	ensure (v)	D.	notify or make aware in advance of something
5.	exceed (v)	E.	connect or set in position and prepare for use
6.	permit (v)	F.	make sure / certain
7.	warn (v)	G.	keep from doing something

10. Read the text “Pipeline Components”. Look at the diagram and pay attention to the underlined terms in the text.

Fig. 3 Components of a pipeline

A pipeline system is comprised of the following components:

1. line pipe – the main component of every pipeline and is usually metallic (carbon steel / corrosion resistant alloy)

2. pig traps – allow safe loading, launching, receiving and retrieval of pigs without disrupting the fluid in the pipelines;

3. block valve stations – isolate section of the pipeline and limit the release of line contents in case of a leak or pipeline rupture;

4. emergency shut-down valves (ESD) – located at both ends of the

pipeline and enable automatic shut down of the line in case of an emergency;

5. slug catcher – installed at the end of a multi-phase pipeline to prevent slugs and to ensure a constant gas flow into the receiving station;

6. cathodic protection system – installed as a backup to the external coating to prevent corrosion of the external surface of the pipelines;

7. pressure protection system – protects a pipeline when the line pressure exceeds ) the max. allowable pressure;

8. telemetry system – permits pipeline monitoring and remote operation from a central location;

9. leak detection system – installed to warn that a leak occurred.
