Practicing in translation

1. Translate the following sentences into Russian.

1. Implementation of operations offshore such as field exploration, well drilling and oil and gas production requires application of offshore platforms.

2. Fixed platforms can be applied only in shallow waters and are installed with their basement against sea bottom.

3. Floating drilling platforms capable independently or by means of towboats change drilling locations are designed for operations in deep waters.

4. Marine riser is used to protect drill pipe string against sea environment in the course of well drilling and production operations and prevent environmental contaminations.

5. In the process of drilling drill pipe string rotates inside the marine riser.

6. In the process of oil and gas production marine riser is used to protect production string located inside it.

7. As long as installation of full-scale processing plant on an off-shore platform is not cost-efficient, only primary treatment is performed.

8. Well fluid goes to separators where it is separated into oil, gas condensate, gas and water.

9. Gas is compressed with centrifugal compressors, stripped and dehydrated.

10. Part of the gas is used on the platform for well injection and power generation, most part is transported to the shore, and only small portion of gas is flared.
