Defnitions and abbreviations

Warning sign is a warning sign with black text on a yellow background

that warns o the danger o getting too close to or touching live parts o

the apparatus that can be dangerous

Work permit (WP) is a written permit to carry out a dened task in a

given place on an installation under given preconditions in a sae manner

Responsible or operations imply overall proessional supervision oelectrical installations, and ensuring that electrical installations are

planned, executed and operated in accordance with the regulations

High voltage installations are electrical installations with a nominal

voltage above 1000V alternate current or 1500V direct current

Earthed means that the electrical installation is short-circuited andconnected to the installations main earth so that electrical energy is

discharged quickly and saely in the event o short-circuiting

Condemned equipment is equipment that has been removed rom

operations permanently. The equipment has been electrically secured

(disconnected and earthed) and all labels have been removed.

Low voltage installations are electrical installations with a nominalvoltage up to and including 1000V alternate current or 1500V direct

current

Preserved equipment is equipment that is out o operation temporarily,but which is expected to be used at a later date. Preserved equipment

is connected to the electrical distribution system. This equipment shall

be maintained to ull saety requirements according to the regulations.

Preserved equipment is marked Preservert

Saety card is a personal card issued by the responsible person

electrical installation, showing authorisation, access permit and

limitations or the individual. The responsible person electrical

installationskeeps an updated list o all saety cards Live equipment means that the equipment is electrically charged

Roles

Responsible person electrical systems has been appointed by BP

current regulations, including design/building o new installations and

contracting o installations and vessels

The deputy responsible person electrical installations is a BPemployee appointed by the responsible person electrical installation to

carry out the responsible personstasks when he or she is absent

An authorised person electrical is a BP employee appointed by

the responsible person electrical installation to ensure that electrical

installations and equipment are carried out in accordance with current

regulations within one installation

A deputy authorised person electrical is a BP employee appointed

INSTRUCTIONS FOR LEAKAGE TESTING

Before work begins

Check- that the pressure gauge and other test equipment has been calibrated and will

withstand the pressure that is to be tested- that the connected equipment will withstand the pressure that is to be tested- that any possible energy reservoirs such as accumulators, pulsation dampers,

etc. have been isolated

When using water as a test medium

- that the foundation and supports for the equipment to be tested will withstand thecombined weight of the equipment and water used during the test

Performance of pressure testing

When using water, the equipment shall be filled to 100% first - ensure that the gas is ventedat the highest point.

1. Increase the pressure to approx. 10% of the test pressure maximum 10 bar.2. Check for possible leaks (flanges, plugs, etc.).3. Increase the pressure gradually to 50% of the test pressure.4. Check for possible leaks (flanges, plugs, etc.).5. Increase the pressure gradually to the test pressure.6. Maintain the pressure for an adequate period of time in order to perform a thorough check

for leaks

- Avoid shock loads- Avoid passing in front of possible leakage points- Monitor any possible temperature variations that can influence the pressure

After pressure testing

1. Reduce the pressure gradually to atmospheric pressure

2. In the event of drainage :

- refill nitrogen at the highest point avoid creating a vacuum

- check that the drainage system is not overloaded

3. Check that all parts of the tested system have been depressurised/drained

low points, check valves, etc
