Rig 25 W.O

Diesel Engine as ignition Source

Current profile:

Rig 25 has two main working Diesel Engine, one is on-Process and other is backup.

Regular path of the fuel Diesel is moving from the main Tank throw high pressure

hoses to intermediate tank connected to a motor which supply both Generators

with fuel.

Safety Issues Addressed:

1- No Emergency Buttons for the Generators.

In case of fire we will be leaved ahead of one limited option of manually

turning off the Electricity switch of these Generators which, as known, will

not cut out any element of fire process (heat, air and Fuel).

N.B: I have discussed this issue

with our mechanic who added

that every generator is equipped

with sensors for heat, fuel

supply..etc., which in any

abnormal conditions should send

signals to cut off fuel supply and

shut off the machine, this

subsequently should prevent

other relevant Engine issues such

as over-speed by controlling LEL

and UEL and surface overheating.

2- No Spark Arrestor Found

This may be not a critical issue for the generators as they normally

located 18 – 20 m away from the wellhead, but this should be considered

for the carrier engine and the pump engine.

Recommendations: we should provide spark Arrestors for these engines

A.S.A.P to prevent Ignitions hazards of H2S Working Environment.

Kindly review this report and advice if any further Safety precautions

required.
