Central to all energy consuming operations, Ion Cells and Plasma Cells are mass-fabricated in huge numbers in the Cell Fab Matrix. The highly-sophisticated production lines are run autonomously and fully automated to increase throughput and reduce the risks of radioactive contamination to workers and engineers. Upon detection of system failures or for scheduled system maintenance, the Cell Manufacturer Complex must first be brought to a complete halt before any servicing be attempted.

The Construction Shop (also known as 'Construction Material Shop', or colloquially, among construction workers, 'The Shop') is a factory compound assembling a wide assortment of materials essential to construction of vessels and stationary installations. It features a considerable number of different manufacturing lines, hence it requires a complex and well-orchestrated supply chain. While most individual production lines can run fully automated, the operation of the compound as a whole is run by a crew of up to a hundred or more engineers and construction workers.
