With the official launch completed on the 5th Feb and the project ceasing on the 31st March this will be the last entry on to the website.

It only remains for me, the Project Manager, to thank all of the hundreds of people that have made this amazing project the success that it has been. To thank the guys like “The Len”, “Pompey” and “Ash” who come back season after season because they just love working in this fantastic place. To thank some of the key managers who have been with the project from start to finish; John Hammerton and Peter Willmott from Morrison Falkland Limited (the main contractor), Peter Ayres and Michael Wright from AECOM (the engineers) and Hugh Broughton from Hugh Broughton Architects. And a very special thanks must go to the BAS in-house team of Paul Cousens, Steve Canham, Michael Rose, Martin Bell, Ben Norrish, Caroline Lewis and Lynne Slater without whose dedication and perseverance this project would not have been possible.

Whilst all the construction work was going on the science team continued collecting data for the long term data sets, ran a full field season from Halley VI, installed a new radar system and installed new instruments in the Optical Caboose and Clean Air Sector Laboratory.

In addition to all that Halley VI hosted two international collaborations. One was a high altitude balloon campaign with the US National Science Foundation to collect data from the stratosphere and the other was a joint Danish / US / UK aerogeophysics campaign to survey the Recovery Glacier area.

So a very busy season.

At the time of writing the Summer Accommodation refurbishment work, the snagging work and the new build Workshop and Stores Building are all well underway and on target for completion by the end of the season. The demolition and clearance of Halley V has all been completed. For many of the staff at Halley this was a sad period because many had lived there for one or more winters and most had lived there for several summer seasons and regarded the place as home.

It was a struggle at first to get the generators up and running, which delayed the programme. So there were a few tense weeks in the middle of the season before the decision could be made that it was safe to strip out and close down Halley V and winter in Halley VI. Once that decision was made at the end of January we all went in to over drive; the comms equipment, surgery and science equipment were moved from Halley V and installed in Halley VI, each module was completed so the BAS staff could move in and fit out with their equipment and the first wintering team had to be trained to look after their new station. Thankfully all the works were completed and the station became operational on 28th Feb 2012.

The buildings are unoccupied and unheated and have therefore built up a layer of hoar frost which conceals their colour.

The modules are survived the harsh Antarctic winter with no problems, and the aerodynamics have worked as designed to keep the snow off the skis.

To get the modules to the new site BAS vehicle managers Martin Bell and Ben Norrish had to tow them 15km over a prepared ice track. It was an impressive sight seeing each blue module glide by at Halley V and the red module just dwarfed everything it passed.  At the Halley VI end it was incredible to see each one appear from the horizon gradually getting bigger and bigger then brought to a stop towering above us just a few feet from the next module. Then came the tricky part, manoeuvring the modules into position. When the modules stop moving their skis stick to the ice. So the BAS Project Manager, Karl Tuplin, used ancient technology “rollers” or in our case some short lengths of scaffold tube under each ski to prevent the “sticktion” and enable each module to be manoeuvred into position to an accuracy of 10mm.

After several years of storage in freezing conditions Galliford Try were keen to test all the generators to make sure they still worked and to give confidence they will start next season when commissioning begins in earnest. All four generators were first checked by setting them up and dry firing them. Then they were tested and analysed under load. Thankfully they all passed with the minimal of works required.

The rest of the construction  team were busy fitting out the internals of all the modules. This included installing the building services, constructing the walls, ceilings, floors and finishes. As you can see from the photos the rooms are really starting to take shape inside.

Having towed the blue modules last year we were confident we could move them relatively easily this year. So the main test for this early part of the season was the digging out and towing of the red module. We had carried out tests in the 06/07 Season and towed 166 tonnes so theoretically the red module should move quite easily weighing a mere 120 tonnes. However, it was still a nerve wracking time for Martin Bell our vehicles manager who planned and organised the move. Although there appears to be an awful lot of vehicles doing the towing these were mainly required to get the module moving and up the ramp. Once on the flat the two CAT Challengers could tow the module without assistance. Once on the construction line temporary power supplies could be connected to all the modules, lighting and heating switched on and construction could commence.

The construction team had to start from scratch with the construction of the red module. The undercroft was delivered in eight prefabricated steel sections. Each had to be pieced together off the ground, keeping them flat and level whilst the hydraulic legs and skis were fitted. The next stage was to build the two storey steel frame fitting the first storey and second storey structural floor panels as they went. Once the frame was complete the cladding could begin. The process was similar to the blue modules starting in the centre underneath working outwards and upwards. The main difference was it was much larger and there were four big window lifts, the two main windows at the front and the two cockpit windows at the sides. Amazingly the module was constructed and weather tight in only seven weeks.

In preparation for the Igarka’s arrival and our own BAS ship the RRS Ernest Shackleton, which had food, fuel and passengers on board, we found a creek with some suitable sea-ice in it, prepared a ramp and prepared and edge.

When each shipped arrived it was an all out effort to get them unloaded and keep the construction site going. At the finish we had completed in excess of 400 sledge rotations just emptying the Igarka and created over 4km of stores lines for the construction site.

Through all this the local penguin population would look on with bemusement. We would often get a gang of teenage penguins, in various states of moult, waddle over and hang around the mooring lines watching us and mess about with the lines and dead-men anchors (just like teenagers the world over).
