Merit was appointed for the supply and fabrication of the mechanical and electrical services installations for the new Halley VI research station in Antarctica.
The project included the provision of all components, plant and materials suitable to be catalogued and shipped to Antarctica for installation on site within the new research facility. Additionally the project required the extensive use of pre-fabrication techniques to reduce the amount of normal build time encountered on site.
Merit undertook and supplied the following pre-fabricated elements of the project:
5 No Module plantrooms
Including complete structure, installation and fit out, including heat recovery AHU and ductwork, LTHW pipework and pumping systems, Hydraulic plant and equipment, Controls panel and interconnecting wiring, full electrical fit out and wiring. The Plantrooms were fully tested as far as possible before shipping, including MCC controls.
Module Service Cassettes
Each module (8 No.) of the new station required the provision of service cassettes providing service distribution from/to 2 No. energy modules throughout the facility. The service cassettes were designed to be slid into the module steelwork on site, and comprised the following services:
- Heating F&R
- Domestic hot water F&R
- Cold Water
- Vacuum drainage
- High Pressure mist sprinkler system
- Electrical Busbar distribution
Within the energy modules, Merit pre-fabricated the entire LTHW pipework distribution system from a fully 3D modelled environment and erected in the UK, before breaking down into spool sections for erection on site. This facilitated the entire pipework distribution system being erected within 4 weeks in the energy modules, saving significant time on site.
Merit was appointed for the design and build of 2 No. water melt tanks for the production of water for the facility. The melt tanks were constructed from 20' ISO containers, and included an integral plantroom housing pumping/monitoring systems and hydraulic equipment. The melt tank comprised of an insulated stainless steel tank with a hydraulically operated lid to enable loading of snow for melting. The tanks were provided with flexible connections for power and LTHW/water pipework, to interface with the energy modules. The first melt tank was put into temporary operation for the construction team on site during the 2007/2008 season.
Merit was to be appointed for the construction of 9 No. caboose units for the project, including research facilities, laboratories and accommodation for remote ice shelf operations. Unfortunately due to budget constraints the caboose package was put back and not undertaken.
