Perhaps a serious post?
I'm in Industrial Services. It's a broad term that encompasses the utilization of all sorts of specialized equipment to aid the SAGD bitumen production facility that contracts my company, make their bitumen/oil.
Generally (at least on this site) we deal with:
- Cleaning and removal of materials from vessels, systems, and the environment.
- Locating and daylighting utility lines buried underground that are too delicate to surface with heavy machinery.
- High pressure water blasting, and automated 3D-cleaning utilizing high pressure water or GAMA-jetting with chemicals to soften and remove debris where work conditions aren't reasonably safe enough for personnel to perform work.
- Venting/Purging/Vaccing sour/explosive materials and gasses from sour processes for maintenance once they are isolated from live systems.
- Scrubbing of sour gasses utilizing chemicals and an H2S Scrubbing unit.
- High pressure line moleing, stinging, pencil lining, and reeling to clear plugged lines.
- Moving solids and fluids around site utilizing vac trucks.
- Chemical injection cleaning of heat-exchangers and vapor systems using boiling hot corrosives. (My current job. I was recently promoted <3 I get to breathe air that doesn't come in a bottle now!)
Basically if it's poisonous, explosive, can cut you in half in the blink of an eye, dissolves you entirely while boiling your skin, sticky, slimy, or grungy: I'm your guy.
Another way to put it is if it's a problem in an oilsands plant and it isn't insulating, pipefitting, electrical work, high angle work, or radiology, my company is probably the solution. I guarantee I'll think of like 5 other things we do as soon as I post this reply, but you get the idea.
