what do i do...
i'm an instrument technician, so basically i'm involved in the maintenance of the rig.
instruments are measuring/indicating/controlling devices that show the pressure, level, temperature or flow of the oil or gas in the pipeline. there are other sides do it (like from time to time i have to make up small piping skids for hydraulic oil systems etc) but thats what i mainly deal with on a day to day basis.
thats a temperature transmitter which gives a reading of the temperature both remotely (on the instrument) and sends a signal back to the control room so they can see if it's reading correctly (and if not i go out and calibrate it).
as for getting lonely, it can be, mainly being away from your family and friends for 2 weeks at a time (i do 2 weeks out there, then come back for 2 weeks) but there's good banter on board, everyone's in the same boat, there's a crew of about 60 people. you get everything paid for, full board for food, you get your laundry done, there's a gym and TV suite and a tax-free shop on board. and yeah, they got the internet. it isn't so bad out there, the scariest part is the helicopter flight out 'cause if it ditches you are dead, no question about it. the north sea is like 6 degrees celsius all year round, so you can't stay in it long. you have to wear like a full set of overalls, ear muffs, safety boots/glasses, hard hat, the full works while you're out on the job. believe me, that's uncomfortable when you're working on hot machines on a hot day :P
anyway, i'd rather do this than spoon out the eyeballs of dead people. that shit would creep me out. i hope you've got a strong stomach, cause i don't think i could cope with messing around with dead folks. not to mention they're EYES. i'd go paranoid with DEAD PEOPLE EYES staring at me all day D:
