Oil Rig Disaster Compilation

[@heyitsjel]

I'm an engineer in the O&G industry (well construction), and can answer the BOP question for you. BOP's typically have several options available for controlling pressure: annular preventer/s; pipe rams; shear rams and blind rams. They all serve different functions, depending on the pipe/casing/tubular that's in the well, or even if the well is empty at the stage it is being used. Similarly, they all have different pressure ratings. This is the reason BOP's are quite large - these several sub-components are all stacked upon one another. The reason you can't just have a valve that closes on the BOP, is that in *most* well construction operations you have a tubular of some sort running through the BOP. As a result, you can use things like the annular preventer - which looks somewhat like a giant rubber donut - to be compressed around the pipe and seal the annular cavity (ie. the gap between the outside of tubular and the inside of the BOP). Given these are large deformable rubber elements (with some sort of metal backup, effectively), they're usually on the lower end of the pressure rating scale, but they have the added benefit of being suitable for sealing around tubulars of various diameters - from small to large. Similarly, they can also be stripped through (ie. the tubular can possibly be moved up or down while the annular is engaged and providing some level of pressure control). These are pretty commonly used for things like back-side pressure tests at lower pressures (eg. packer or casing tests). In contrast, the next option being the pipe rams rely on you knowing the outer diameter (OD) of the pipe that is situated across the rams - and you typically have a given set of variable bore pipe rams that are suitable for sealing a specific range of tubular OD's (eg. 3-1/2" - 5-1/2 and 4-1/2" - 7" OD; different rams). As a result, if the equipment across the BOP (aka. "the stack") at the time is outside the OD range of these rams, then they can't be used (ie. won't seal and/or will cause mechanical damage to the rams/equipment). If the equipment is in the range of the OD's, then you use the appropriate pipe ram to seal and usually with a higher pressure rating. The added benefit of the pipe ram is that you can usually "hang off" the tubulars in the rams, provided the weight is within the design range. This potentially allows you to disconnect yourself from the drill/tubular string without having to shear the pipe - provided you've got the right equipment in the hole to allow this disconnect. Next you have the shear rams - and they're literally as the name suggests - designed to cut through tubulars of certain size/wall thickness and seal the BOP. Typically reserved for critical situations, and sometimes testing when there are no tubulars in the well. These usually have pretty high pressure ratings. Finally there's the blind rams - these are literally to used when there's nothing in the well, and they seal the BOP. It's not uncommon to find combination blind/shear rams (ie. the shear rams are used as blind rams when there's nothing in the well). Again, these also have pretty high pressure ratings. Now all the above sounds fairly straight forward - but keep in mind this is just the function of the individual rams/annulars. There's nothing on the BOP side that stops potential influx from *inside* the tubulars. As such, you typically have some sort of well control valve that you will install on the tubular string (eg. TIW's, Full Opening Safety Valves etc.), or something like the IBOP's (Internal BOP) on the top drive, in order to control the influx of fluids from inside the pipe. You actually still need to know exactly what tubular is across the stack at all times, and also where any changes in OD are on the given tubular (eg. drill pipe body may be 5" OD, but you also have tool joints that are around 6-5/8" OD, for about 1-2 feet at each end of the pipe... so you need to make sure the tool joints aren't across the given ram/annular you're planning to seal with). Also, on semi-submersibles and drill ships, the drill string will heave with the rig (ie. move up and down with the wave motion, as the rig/ship rises and falls); while the BOP is effectively locked to bottom on the wellhead/conductor. As a result - in anything but perfectly dead calm weather - you need to ensure you have some sort of motion compensation activated for the drill string (eg. compensator; or active heave draw works). This effectively tries to counteract the movement of the rig by moving the drill-string up or down in the opposite direction to the rig movement, making it somewhat stationary downhole. If you don't use such compensation and you close the annular, you'll effectively be stripping through the annular constantly (ie. moving up/down) and will wear it prematurely, and possibly damage it (eg. changing OD such as the tool joint trying to pass through it). Similarly for the pipe rams - if you manage to shut them on the pipe without compensation - you're effectively locking the pipe to the seabed... so the pipe left between the pipe ram and the rig floor will effectively be exposed to the tensile and compressive forces imparted to it as the rig heaves up and down. This could buckle the pipe in the riser; part the pipe under tension; or even damage the rams. Oh, and for semi-subs and drill ships you also need to take tidal movements into account - as this can move your pipe potentially several meters (ie. 20ft) relative to the BOP, depending on if it's high/low tide, and the tidal patterns in the region you're operating (some areas have crazy tides moving large distances over short times, while some have minimal movement over the same relative time).

[@heyitsjel]

Following up on this - even if you do manage to shut the well in with an influx inside the well/pipe - you then need to remove the influx from the pipe/well, and regain well control prior to proceeding. This typically involves monitor pressures and volumes; followed by controlled circulation of the well fluids to displace the influx. Typically this involves sending *small* amounts to the vent lines/separators during the controlled displacement. Similarly, it may involve weighting up the drilling fluid to be pumped, and this all takes time. Keep in mind that a gas influx into the wellbore will usually have *significantly* higher pressure and volume than a small oil influx. ie. the gas is essentially massively compressed and likely partially dissolved into the formation oil (or even potentially into oil/synthetic based mud). This compressed gas typically is more buoyant than the other drilling fluids and wants to migrate towards surface. As a result, you can end up with a slug/volume of gas at high pressure (ie. not that far off reservoir pressure) trapped below the BOP. You can think of it along the lines of when you do try to bleed off pressure, you end up with a large volume of gas being circulated, but only a small change in pressure (ie. the gas is highly compressible... so it's expanding significantly as the pressure drops). For anyone interested, there is a technology around called Managed Pressure Drilling (MPD). Essentially it's like drilling with a rotating BOP annular which is constantly active during the drilling process, and you have a series of valves (chokes) on the outlet side of the circulation system... effectively by choking the outlet side of the circulation system, you artificially increase the bottom hole pressure exerted on the formation/reservoir. This is *only* during circulation however. These systems do have limitations as far as pressure is concerned, and are quite complex in their operation... but they allow you to drill through difficult formations by adjust downhole pressures on the fly; allow you drill faster via lower overbalance (and therefore lower confining pressure); potentially lower formation damage etc.

[@waterlinestories]

Thanks. I really appreciate the detailed information. Really interesting for laymen like me.

[@EShirako]

@@heyitsjel Yeah, I suppose if you fracture a level of rock in the formation by providing too much pressure that it can't handle, either the oil might start escaping all over the place when it shatters into chunks, or the layer may compact under the ocean's pressure, giving you a not-quite-rock layer that will shift when you try to get through it again. That would be bad and complicated..!

[@Grognarthebarb]

So basically these BOP while seen by the public as the last resort perfect solve all safety equipment are actually very finicky and require very special circumstances to be able to work properly

[@Orcinus1967]

[@ixxieangel]

It is absolutely insane to me that the paperwork for different components of the same repair job weren't kept together while the job was ongoing. A paperclip or stapler and a end of shift discussion would have saved a crew full of lives, the health of the North Sea, an entire oil rig, and millions/billions of dollars.

[@charlesreid9337]

I am pretty sure that is company bulshit. Lockout procedures for complex systems like these existed longer than I've been alive. Actual engineers I would have created precise step-by-step instructions on how to do these maintenance and repair operations. That would include literal locks , safety tape lockout tags etc. you probably seen these if you've been in a factory or a mill. And the only people who would be experts on this rig would be the engineers.. that would be to investigators talk to. So it sounds to me like the engineers were covering their ass, or this some management d******order that supervisor to cut it on anyway, or something similar. A simple accident is going to cost the company a lot less money than outright negligent buy a manager or its engineers. One costs you an insurance company some money. The other costs the rig operator 10s or hundreds of millions

[@ssokolow]

It always surprises me that Piper Alpha didn't have some kind of lockout-tagout system in place for "not to be started under any circumstances" situations.

[@killerzer0x74]

The very first thing I thought was "why is this critical info being left on a random piece of paper that nobody would assume to read?" Always have a box for critical info at the entrance that people MUST walk by and see before starting the shift...or just use computers and require the system to be checked for critical info.

[@jamesdowis2346]

When did they actually start using lockout tagout procedures?

[@sammie6791]

Piper alpha was the catalyst for the systems used in offshore drilling today.

[@theunemployedtrucker]

It's absolutely ridiculous that the other 2 platforms continued pumping oil and gas even though they could clearly see the flames from 20 miles away. Not having authority to shut down production is ridiculous but unfortunately it shows the mentality back then that production takes priority over everything else basically because of money. It seems unthinkable that production superseded lives.

[@Master-Disaster]

Yes, but even if they had stopped pumping, because of the pressure and inventory still in the piplines, the contents would still have come out and fed the fire. It has always been a bit of a myth that if Tartan had stopped earlier, lives would have been saved - they wouldn't. But still not great.

[@fr89k]

Not a mechanical engineer and not in the oil industry, but: A BOP is designed to shut the well in a reversible way. First, you can have Annular Preventers which are annular rubber tubes which can be inflated by hydraulic oil. When they are inflated, they press tightly against the drill pipe, sealing the well. Next, we have Pipe Rams. They close the space around the drilling pipe with thick steel plates which have an opening for the drill pipe, thus leaving it intact. Finally, we have Shear Rams and Blind Shear Rams which cut the drilling pipe. It's the last resort. So in summary: Yes, there are reversible methods to seal a well but the last resort is always an irreversible method which has a higher reliability than the reversible methods.

[@bluebelle8823]

I do wonder if the irreversible method is considered cheaper too. Cheaper to install at the outset and bank on it never being needed. The others sound like they may require more upkeep and would almost certainly require regular testing, costing money in the form of shut down time. These companies definitely put profit ahead of all else, the question is how far does that go?

[@fr89k]

@@bluebelle8823 Kicks are a common occurrence during drilling, so you need to have reversible methods anyways.

[@heyitsjel]

@@fr89k kicks are significantly less common offshore - at least in today's oilfield - where things are more regulated. The few times you hear about kicks these days, are usually in exploration wells where the subsurface geology and pressure regimes aren't understood so well (ie. encounter an unexpected over-pressured zone with not enough mud weight in the hole; and as a result you take an influx). US land... well that's a different story. It's the wild west.

[@heyitsjel]

@@bluebelle8823 the irreversible "permanent" option is basically cement plug/s placed to isolate production zones (ie. mitigate cross-flow between subsurface zones), and also cement plug/s isolating producing zones from surface/shallow zones. Without going into too much detail, it depends on the region and regulations you follow eg. UKOG; NORSOK etc., but some require the cement plugs be placed "rock to rock" ie. the casing must be perforated; milled or similar, to allow the cement plugs to seal without relying on the casing (which could ultimately corrode or fail over time). The number of cement plugs is ultimately determined by regulations, and operational capability/requirements. eg. you may place one long plug (eg. a 200ft combination plug), or maybe multiple smaller plugs (eg. 2x 100ft plugs). Usually 100ft is the *minimum* for a single barrier, assuming it's all good cement. Ideally a few hundred foot for each plug is good practice, in order to ensure that at least 100ft of cement (per plug) is considered of good quality. In horizontal or highly deviated wells, cement plug placement can be a little more difficult, as the cement typically wants to "slump", which can result in channels near the top part (highside) of the wellbore. There's numerous ways to overcome this problem, like pumping thixotropic cements (ie. thickens / becomes gel-like when it's not being pumped, while it's curing); and also using specific cementing tools (eg. kick-off tools) to prevent the cement from being disturbed once it's been pumped.

[@MF-le7fp]

So essentially, (unless I’m missing something), the catastrophic disaster that occurred on the Piper Alpha platform could have been averted with a simple hand written notice left on the control panel by the day shift engineers stating, “To all subsequent shift engineers managers...Do NOT start Pump A under ANY circumstances! The Pump A safety valve is only HAND TIGHT at this time! See safety valve paper work.” ~The day shift control room manager Unbelievable... 😐😫😤🤯🤬

Working from the Sedco 704, I was a diver on the Piper Alpha in 1977. During that period it was common for at least one of the flare stacks to develop a leak, and I have photos that I took of one of flare stacks melting, then falling into the sea, with black smoke curling up into and above the helideck. As I recall, the platform was much rusted out underneath the sea. In those days I also worked on the Claymore platform. Photos I took at night from the Sedco 704 when it was about quarter mile from the Piper show a beautiful, golden, spectacular night scene. It looked paradisical, but in reality it was the fire of hell.

It hits home when I hear people losing their lives on oil rig. My dad worked at Aramco plant in KSA for over 30 years. He is known as crazy dad in our family because he does some crazy and borderline dangerous things, which normal folks won't do. For example, he will unscrew the 30 lbs LPG/Propane tank and light it up directly at the tank opening. You might think that the tank would explode. But it doesn't. As everyone around him would panic, scream and run for life, he would laugh and put his hand over tank opening and extinguish it. But even such daredevil man - my dad told us to never work on oil rig or chemical plant. He doesn't tell us about his bad experiences but we guess that they bring bad memories to him.

A blowout preventer generally has multiple phases of operation. It can be operated in a non-destructive way, like you asked. But if pressure control is completely lost, it can exceed what these valves can contain. They work using annular preventers; Deepwater Horizon's just failed. BOP's, as far as I know, already work like you say; severing the line is merely the final step where even the 'shutoff' failed to stop the flow. The Hail Mary, if you will.

[@deathbycheese850]

It wasn't that they didn't know how to use it, there was an electrical fault, caused by an open porthole, which they had no idea about, at the time.

[@Mike-tu7uw]

@@deathbycheese850They knew just enough about the system to be dangerous. Training was lackluster at best and safety was a “dirty “ word

[@charlesreid9337]

So the first one confused me. The way you explained it it sounds like everyone made reasonable decisions and an oopsie happened. But this is not how safety on complex systems works. Lockouts have been a standard on industrial systems, factory machinery add everything else for a very long time, Actual engineers not mechanics weather design precise procedures for safety lockouts.. especially for things like safety valves. It would be a well bubba nose sort of thing there would be precise instructions, literal locks , red or yellow safety tape. It is insane to leave any high pressure pipe anything hand tight. The location of those maintenance checklists shouldn't matter. The engineers job would be too specifically designer procedure where accidents like this can't happen. Somebody f***** up here or multiple somebody's. 4 as we are in children most likely a manager told the supervisor to just turn the f****** thing on. Unforeseeable accident is going to cost a company a whole lot less money than management making stupid and negligent decisions.

Avafors 1959 - 1983. 150 meter long, 15 350 dwt. Built in Gothenburg 🇸🇪, sold, renamed Yampol (of Odessa) and broken up and used for it's steel in Split, then Yugoslavia 1983. For what I can find, Avafors was one of the smaller ships built by Götaverken that year. The Trinity Shipper (though not a bulkskip) seems quite impressive , and M/s Malgomaj. Not comperable. But anyway

The Deepwater Horizon's EDS failed to operate because A) Its batteries were weak and hadn't been checked in however-many-years. Perhaps 10 by then, I think he said? B) The 'Blind Shear Ram' was a 'slightly-lacking design' which only worked about 50% of the time when commanded to close the well. A number of fault-conditions, like a torsioned or 'folded' pipe might present a 'stiff line' in its fold or torque-area which is notably-harder to cut through. C) There were other issues, many many of them, in fact, but one of the few biggest remainders is that the BOP and the Dead Man Switch had been un-tested and unmaintained for years; both of the redundant control modules in the Dead Man switch portion were unable to operate. One of them had SOME voltage...maybe enough to activate the shear ram, maybe not, but it never got to try because its solenoid had failed over the years, and it was unable to hydraulically-activate its shear-ram. The other control unit had dead batteries...both sets of batteries were dead, so it was useless. AND its solenoid was also unusable, I think, but it had no power to even try anyway. The other module had one dead battery pack, and the other had all of NINE volts. 9, out of 27, I think. Why 27? I forget...something about their chemistry. Anyway, this was a stupid design in the first place because somehow the BOP control modules didn't realize that their batteries were not just 'down one or two cells' but 'so dead that they were utterly-inoperable', and had been like that for a long time? It doesn't do the kind of self-checks my $100 UPS under my DESK does?! Nope, it doesn't. Which is even more embarrassing if you remember that the device was in constant communication with the topside systems. It could have spared a small circuit to let it do full offline battery checks by having one control pod try to switch over to battery power and judge how fast its voltage goes down. "Not being UTTERLY dead" doesn't take a lot of IC smarts, soooo that should have been easy. I'll make a WILD guess and say that that BOP was popular not because it was top-rated for safety and effectiveness in its stand-alone dead-man mode, but because it was the CHEAPEST thing that 'technically' fit all of the job requirements. Deepwater Horizon was entirely preventable on several levels...and everyone saved a buck, so those levels were bypassed or ineffective.

[@AliG-iq4gd]

I worked with several guys who had been on Deepwater Horizon for many years before. I ventured "Jeeez - you guys dodged a bullet there!" Someone else responded with "It might not have occurred had they been on board". One of them may have queried the whole process of abandonment and pushed back hard enough. You never know.

[@EShirako]

@@AliG-iq4gd That totally does make sense. I know they were being leaned-on to reduce worker hours and costs because of the platform cost overruns, and rig workers apparently make a good bit of money. If the guys who were there were less stretched-thin, or if there were more people there to let someone spare more than tenths-of-a-second at a time, they may well have avoided it. ONE person with a spine calling B.S. on the 'bladder effect' claim, or activating the EDS before the circuit was destroyed (and thus when rig power was still available to it, I believe?) would have avoided most or all of the issue...it's sad.

this video is really well put together and highlights some incredible footage. but honestly, while it's fascinating to watch, it does make me wonder if we're focusing too much on these disasters instead of finding sustainable solutions for the future. what do you all think?

With Accidents on Oil Rigs, I am always more concerned about Spilt Oil & The Environmental Impact on Marine Wildlife for years to come, Damage from some oil spills will be felt by Ecosystems for hundreds of years to come.

[@SuperLordHawHaw]

51:44 I'd say this is addressed by training and checklists, similar to what pilots use. If the information you are getting matches certain conditions then you take action X. Repeated practice with training removes a lot of the emotional obstacles. 52:00 There is nothing wrong with starting with the "least costly remedy", this is a form of triage. You don't want your doctor giving you dozens of x-rays every time you get a headache. There are other actions available to stop a blowout before you have to sever the pipe. Unfortunately it turned out that the blowout preventer was incorrectly configured. Now what could be coming into play is "What if the info is wrong?" and the penalty for making a mistake could be career destroying. I doubt you'd get a pat on the back and "You did your best with what you thought was happening. It is ok that we've been put a month off schedule." so they are very nervous to take quick and decisive action. The USCSB did a very good analysis of the Deepwater Horizon failure. kzbin.info/www/bejne/fHS5dIKNms-fl8k

[@deathbycheese850]

I think you got your place names wrong. Ardersier is on the opposite side of the Moray Firth, nowhere near Nigg, where the platforms are constructed. Nigg actually sits at the mouth of the Cromarty Firth, where you will see numerous rigs either waiting to be towed, or still under construction.

Yo, kind of a dumb thought but to answer his question about a EDS system that can be turned back on.... Shear force is stronger than Lateral force, why not "twist" the tube to "pinch" it shut. Might need a different tube than metal pipes

[@daveevans1236]

Re pipa alpha. OK massive failure in the permit to work procedures. I can't understand why there was only 2 of these pumps if were so vital. I can't understand why when removing the valve a blanking plate was only fitted hand tight. Mind-boggling!

[@TheronAnderson-hy3lp]

I was born and raised in Alaska, if you move there and are persistent, red tape is cut by government and a barrel of oil stays above 30-35$ a barrel you’ll get a job on a oil rig. Or at least goto work in the oil fields. It’s the coldest weather I’ve ever been in and all you do is work 12 hours a day minimum 7 days a week. I worked 6 weeks on 2 weeks off for PGS doing seismic and spent 2 years working for pool arctic Alaska. Not sure if either still exist but ConocoPhillips is always hiring.

Maybe there isn't any way to make oil rigs safe, I wonder if it could be taken over by robotics to do the job instead.
