12.0 Environmental systems

Of all major ship's systems, life support and environmental control are amongst the most critical. Every key system (basically every system) is designed with multiple redundancies to provide for maximum crew safety, even in the unlikely event of multiple system failure. Under normal operating conditions, the mean time between failures for the environmental systems should exceed 800 years. Even under such a total failure, emergency backups should ensure crew survival.

The primary life support systems comprise two parallel systems, each serving as a backup for the other. Synthetic gravity generators are located throughout the habitable volume of the ship. Each major life support facility includes a tie-in to the reserve utilities distribution networks. These tie-ins include a limited supply of the most critical consumables, like water, food and power. The RUD network is designed to provide minimal life support and power in the event of complete failure of both primary environmental systems.
