How safe are oil rigs?

These are really unbelievably huge structures capable of withstanding very rough seas and most weather.  Whenever there is very severe weather, the rig is shut down and the workers are evacuated.  Here is a website that may be useful.  It includes first-hand person reports of what a typical day on an oil rig is like:\n\nhttp://www2.offshoreguides.com/Old%20Stuff/a_typical_day.htm

All rigs nowadays use rotary drilling technology.  As the hole is drilled, drilling mud is pumped through the drill pipe, out through the bit and up the hole to the surface.  This is to stop the hole from collapsing as it gets deeper.\n\nOn land, rigs really only vary in size, sophistication in pipe handling technology, and horse power.  \n\nThe marine environment is a bit more varied.  The drilling equipment can be mounted a swamp barge for shallow water (as used in the Niger Delta for example).  \n\nNext in scale would be a jack-up rig.  These can be extremely large (Maersk rigs are some of the largest in the world) but are limited by water depth owing to the length of the jack-up legs.  These rigs are towed into position, then the legs are lowered into the sea bed.\n\nDeeper water requires the use of a semi-submersible rig (semi-sub for short).  These rigs are sailed into position, and then partially submerge in order to gain great stability.  They also require the use of anchors.\n\nIn the deepest water, drill ships are used.  They cannot anchor because of the water depth.  They stay in position by the use of GPS in combination with powerful thrusters.  The ship has to be able to rotate around the drill string in order to face into the weather.\n\nAll of these rig types are not the same as production platforms.  Although these have drilling capability, they also produce oil and/or gas.  Mobile drilling rigs just drill and test the boreholes: they do not produce hydrocarbons.   \n\nA short summary.  Try websites such as Transocean or Glomar drilling companies for some pictures and more detailed explanation.

Propane anything is nothing to play with unless you know what you are doing. TAKE IT TO A PROPER REPAIR PLACE AND HAVE IT CHECKED OUT! Propane is safe if the equipment is properly maintained if not I hope you have good insurance on your life and your property. And please make me your benificeary on a good sized settelment...

ya its safe. i have one tooo

Yes it is perfectly safe, The device will only draw the current it requires. So as long as you are providing at least 300mA the device will operate without being damaged.

It is better to be safe than sorry. So, if I were you, I would list those items. Especially, the dry ice.

Actually there is a guideline for Shipyard Work under the factory act. You can check from the particular reference.  Alternatively, you can seek help from your RSO to help you in drafting the risk assessment. I think one of the consideration is the operating voltage on the ship while the other is the supply for the generator.

No business is 100% safe.

Absolutely not, it is perfectly safe.

A drilling rig or oil rig is a structure housing equipment used to drill for oil or natural gas from underground reservoirs. Sometimes a drilling rig is also used to complete (prepare for production) the well. However, the rig itself is not involved with the extraction of the oil, its primary function is to make a hole in the ground so that the oil can be produced. Drilling rigs can also be used to drill for water or for exploration purposes, or to obtain mineral core samples.

The worker left the oil he spilled on the floor. Unsafe act creating an unsafe condition. The old stop training heh?

I keep saying there is no risk, but somehow, all the ones I pulled out without safely remove keep damaging.\n\nXLMan

We drill holes and pump the oil out. The best wells then inject something in the oils place to keep the ground from sinking and maximize the oil you can get. The cost varies greatly depending where and how deep the oil is. If it is 200 feet down in your backyard, not too much. If it is in the Bearing Sea, a ton.

None we keep all our oil just in case.

"safe as it could be" is a very subjective statement. Life is full of risks. Reason and experience has to be in the equation with regard to risk and safety\n\nI don't know all of the history of Ford and gas tanks before the Pinto problem but if it was their first problem with gas tank ruptures leading to serious fires then maybe the Pinto design might be considered "reasonable" but the Crown Victory problem and the Chevy pickup gas tank problems are not reasonable designs. The learning curve from the Pinto should have raised the bar for gas tank placement with regard to safety.

Lift the bike above your head with one hand and apply the oil with the other while using your head to rotate the pedals \n\nImportant safety precaution: Wear goggles to keep oil splashes out of your eyes and a crash helmet because the pedals keep hitting you in the back of the head and then you drop the bike.\n\nEasy!!
