How Long Does An Oil Rig’s Supply Of Food And Drink Last For?
In the North Sea, helicopters usually fly out to the rigs every day or so, with crew and small supply items. Also, supply ships usually visit once or twice a week with bulkier deliveries of fuel, water, chemicals and materials.
I remember years ago whilst working on a rig, the perishable salad stuff running out after a storm had prevented re-supplies from reaching us for a few days, but there were plenty of other bulk supplies on board. The rig operators plan for this sort of thing of course.
As for fuel – the rigs only drill the boreholes, and do not produce the oil. On the bigger production facilities, you cannot just tap into the oil stream, because it’s crude oil, not refined. So the rigs have to use fuel oil and diesel for their enegy needs, just like everybody else! That said, some of the excess produced gas can be used for on-site electricity generation. I think that some of the production facilities are also now using wind and solar power to supplement their energy needs.

It’s a continual rolling replenishment system. No, they don’t burn their own oil, that’s not refined. It’s diesel/gas oil that’s delivered by tanker.
1my hubby worked offshore and the were helicopters going to the rigs many days a week with supplies, don’t know about electric cos hes not here to explain that!
2Hmmm, lets think, they have big generators onboard and suck fuel out of the sea – cant see power being a problem. The power will work the desalination plant to make the drinking water and they are surrounded by fish so I guess as long as they have fishing hooks!
3Seriously, they have to get the fuel from shore – non there that they can use and same with the food. I think the limit would be how long these last – perhaps a couple of months (winter storms might cut it off for a week with 2 crews on board so have to cater for that)
