they could have hit shallow gas pockets while doing soil test DRILLING. comprende?

the power pack in the engine room exploded. my desk mate in the previous company was the 2nd e on duty that time. 20% burned. just woke up from the coma yesterday. the deceased was also my friend an ETO on duty.

What power pack?

During drilling, DPS should be running, engine stop.

Engine room is enclosed space.

Is DPS electrical powered?

sorry bro. don't know detail enough. later when he can speak normally in the hospital, i'll go ask him about it for you....

Thank you.

Thanks.

Awaiting final investigation release

Interested to know how they are doing the soil boring/drilling and what kind of well control equipment installed. (Rig will have diverter and large flow line to divert the shallow gas). Also being a floating vessel, is there any emergency disconnect sequence in well control event?

I was right to guess that they hit shallow gas pockets while drilling for soil boring. It’s the only logical explanation how the explosion was triggered. The engine room would not have exploded just like that if there had not been a presence of gas.

But I am surprised that they encountered gas at a very shallow depth ie 38m from mud line.

How did they miss the gas pockets when they had done shallow seismic survey prior to the soil boring? I hope they actually did the survey.

Someone will have to pay the price...

Imagine if they were driving piles to fix a jacket to the sea bed, and they hit the gas pockets. The cost could be catastrophic to the owner. I don’t think there’s a mechanism to divert gas while driving piles or even conductors!

During pile driving, is it possible for a gas to travel to surface?

There could be shallow gas pockets below mud line dear.

If I remember correctly, there was an incident several years ago when a pile hit a shallow gas pocket, causing loss of support under a mudmat, the jacket to overturned. Part of the site specific investigation is a shallow seismic survey. The platform will be relocated if shallow gas is detected.

One of the objectives of conducting shallow seismic survey is to scan for any shallow gas pockets within 1km depth from mud line. This scan should be done prior to doing any kinds of drilling or pile/conductor driving at that location.

guy i tot tis is about the careers in oil & gas companies, how come it has bcome a news section?

because its interesting. keep em coming.

Safety is the biggest responsibility of oil & gas personnels. We need to know the safety, hazards, causes and mitigation. We need to contribute to improvements.

It is not all about salaries and opportunities.

Correcto.

I am on pigging service line, I noticed that client tends to ignore some of these things in order to get the job done. We, as contractors, can only remind them the consequences as well as put up with the office.

I guess for SEA region, safety is not their utmost priority despite of having thousands of safety programs going on. E.g. this 1 company requires every personnel to submit non safety compliant behaviors or conditions to them even at times there are none.

Yeaps, im in construction / maintenance. Its worst when client is not technically verse about the job & only know how to push push push push to make themselves look good.
