hi
re the questions,
power is from four 120kw gensets built into the modules, and five mobile sets. we have an average load of 150kw at any onetime due to the hvac systems and 3 phase kitchen equipment, it runs on avgas, jet fuel because of the low temps (-70) out there.
yes, it is all on skids that lower and raise to get out of the snow, two years ago it was transported 25km to avoid a huge ice crack 80m wide. It took six months to move the station one year and six months to move the labs and storage modules, this was due to only having daylight for six months in summer.
The modules weigh over a 100 tons each so they don’t need fixing down plus every year the complete site has to be lifted 2m to account for the snowfall. It is an aerodynamic shape designed to allow the fine dry snow to pass under and over and not form snow tails but if you look at the central bridge it has a huge mound behind it, and this is due to the lack of aerodynamic profiling. There is one major problem with the snow there and it is because of the lack of humidity, 0.3%, not a typo, its like ultra fine sand and the wind whips it up like a sand storm and leaving behind mounds of deep power snow that you just fall into because the vis is so bad some days. Halley 6, is almost the centre of the ozone hole so the uv is 100% all the time, day or night, which means you have to cover yourself in sunblock because within 20 mins you have very bad burns. it may look amazing but its a very dangerous place if you take your eye off the ball for a moment, we have had cases were members have lost all the toes through frostbite and trench foot, but in most cases accidents happen when people ignore the rules of this place. British Antarctic survey do an amazing job with providing equipment and training so we can come back after a tour safe and well. I guess that goes for all the countries out there however the Russians seem to love using old Cold War dozers and planes, they work but need some serious looking after. We still use old DC3’s to travel across from bases, they have better engines now but not pressurised so 6, hours at 15000 ft gives you a mighty headache for days
I have a picture if anybody want to see it.
Hope that answers a few questions you may have and if you can view the BBC player they had a documentary about moving Halley6.
The only problem I had with the drones and thermal cameras was steaming up and I started to use ND filters but found the colour had a yellowish component which was a bugger to take out and colour match to B-roll with no ND so stopped using them.
