Construction

The construction season is now in full swing, and the new station is starting to take shape. As the first module has been through all the various stages of construction it’s possible to see the process of building a module from start to finish. Here’s a pictorial guide to building a Halley VI module.

The steel space frames were towed to station on temporary skis. This reduces the weight of the frame for the journey across the sea ice. The frames were then depoted until the end of relief when work could begin.


Temporary skis are used to move the space frames to station.

The frames were then craned onto a levelling platform so the temporary skis can be removed.


The frames are lifted onto a platform so the permanent skis can be fitted.

The permanent legs, which include hydraulic rams for raising the level of the building and much larger skis are fitted. The frame is then towed to its build position.


The module is towed to its build position.

Much of the mechanical and electrical installation has been pre made in large sections to minimise work time on site. Here we see the main pipework being slide into the building undercroft.


Large pre made sections of pipework reduce the amount of work on site.

Next the floor panels are attached to the frame.


Wooden floor cassettes are attached to the frame.

At this point all the large items must be loaded onto the module. This includes large items such as the generator cabinets, fuel tanks and sewage treatment plant. Once the rest of the steelwork is in place it would be impossible to lift these items into place.


Generators, control panels and fuel tanks are added to one of the energy modules.

Many of the rooms come in the form of pods, with all the internal fittings already complete. The pods greatly speed up construction as they just need to be lifted into position and connected.


Bedrooms are pre made as pods and craned into position.

Once all the large items are in place the steel framework is built up and the module starts to take shape.


The steelwork is fitted.

The nose cone is fitted last of all, the first Halley VI module takes its final form.

The external cladding panels for most of the modules will be arriving next year. Large tents are being used to protect the modules from the winter weather and allow internal fit out work to continue in bad weather.
