  1. Give the definition to the following:

  1. Clear liquid without color, taste and smell -

  2. Installation for filling and emptying tankers -

  3. Natural gas under the big pressure that is refrigerated to a very low temperatures -

  4. Vessels having double lining and specially designed to withstand low temperatures -

  5. Salt caverns for natural gas storage -

  1. Define the meanings of the noun with the adjectives on the right. Translate the resulting combinations. Use them in the sentences of your own.

  1. State — aggregate, gaseous, liquid, refrigerated;

2. Gas — liquefied natural, natural, raw natural, refrige- rated, exhaled, exhaust, compressed natural.

  1. Answer the questions.

L What is LNG? CNG?

  1. What is the temperature of cooling for LNG?

  2. What state is suitable for LNG tanker transportation?

  3. Do LNG tankers need special terminals for loading and discharge?

  4. LNG tankers can use this emissioned gas as a fuel, can’t they?

  5. Do you remember the largest exporters of liquefied natural gas?

  6. How many terminals intended for gas reception are there in the world nowadays?

  1. Fill in the missing letters, make up the question and answer it.

...epth, col...r, pr...ssure, temperat...re, transportation, emissi...n, sha...e, gas...ous, withstand, termi...al, ...ontainer, c...llect, liq...id, installation, na...ural, aggregate, quant...ty, r...main, trans-...hipment, ex...aled, t...ste, ...olume, sm...ll, regu...ate, underground, desi...n, construct, fu...l, ene...gy, transmission, explo...t, dista...t, Europe...n, e...ectrical, ...pe- cially

The question ?

Your answer .

  1. Write down the dictation and correct yourself. Write the numerals in words.

In purpose of promoting understanding of LNG safety, many modeling of possible disasters have been made. For instance, modeling of catastrophic outpouring from one tanker container which has 25,000 cubic meters of LNG has been made. Time till full combustion according to results of the modeling was 37 minutes in case that hole in container is five meter long, and 64 minutes if hole’s one meter long. In case of one meter hole and wind with speed of 1.5 m/s, lower inflam-

mability border would be remote 4 kilometers from container, and in case of the wind with speed of 5 m/s that border would be only about one kilometer. Lower border of inflammability is the gas concentration of five percent (gas burns only in concentrations between 5 and 15 %).

  1. Choose the correct verb in each sentence.

  1. Risks when resembling/handling with LNG are co- ming/going from its three characteristics: dispersion, inflam- mability and extremely low temperature products.

  2. Extremely cold LNG can inflict/transport direct conse- quences and bring/cause wounds or damages.

  3. Steam cloud that turns/keeps up upon effusion can if carried/waited with wind get at inhabited areas, and if there’s a gas concentration in this steam between five and fifteen percent then this steam is very easy inflammable.

  4. Fire that resulted/leaked from this process is giving extremely high temperatures. Good side of LNG exhalation is the fact that it heats itself and that steam rises in air (created gas steam is easier than the air).

  5. LNG isn’t inflammable all by itself and statements in sense of: “LNG tankers are sailing bombs” are not correct, because LNG is not inflammable so it cannot exhaust/explode.
