In the most critical areas (bridge, engineering, weapon operation, etc.) additional backup systems have been installed to provide temporary life support while work on primary systems is performed in case of failure.  The latest developments in air filtration and purification systems have been incorporated into this vessel.  All systems within this department are monitored several times a minute.  Any performance deviations beyond prescribed parameters will alert the Engineering department that a problem exists and provide them with as much information as can be determined.

Speaking of the system in its entirely, the quality of the primary systems, combined with the number of redundant backup systems, should render the system immune from total failure from the standpoint of statistical probability.  Even if such an event should occur, the crew should be able to restore at least a basic level of serviceability to the system for at least one section of the vessel.  All systems are connected to the reserve/protected utility grid to provide at least a small level of service to the vessel.  A number of areas of the ship, designated as survival shelters, can be serviced by a number of primary and secondary conduits and lines.

A large amount of ductwork has been installed throughout the ship to accommodate the air-processing system needed to maintain a viable atmosphere aboard ghop qeylIs.  There are a total of twelve processing stations incorporated into the primary system utilized by the ship with nine of them operating at any time, the remaining ones undergoing normal maintenance procedures.  It is possible to operate as few as five systems without a noticeable decrease in air quality for periods of up to 20 hours.  A third system operates to supply atmosphere to critical areas of the ship at 45% the capacity of either primary system.  This third system is completely isolated from the two primary systems to prevent a failure in one affecting the operation of the other.  These processor units contain multiple scrubber units intended to remove particulate matter and any known viral substances contained in the air supply.  This system also governs the temperature and humidity levels of the air aboard the vessel.  Reoxygenated air is then circulated back into the vessel.  Should there be a significant failure of the system, unneeded areas can be sealed off from life support service to allow the remaining air to be concentrated in shelters and work areas while repairs are conducted.  Critical operation areas are also equipped with a device to conduct atmosphere replenishment operations just for that area.  It can provide up to 30% of the quality of the output of the primary system so it intended only as an aid the backup system or for brief use by itself in a crisis situation.  In such a case, personnel will generally utilize the air tanks and environmental suits stored in corridor and other emergency supply compartments.

The air processing system is also useful in the event of combat aboard the ship resulting from insurrection or boarding by hostile forces.  With authorization from the Commanding Officer or Chief of Security, gases can be injected into the atmosphere processing system to incapacitate or kill hostile forces.  A number of hatches in the ductwork can be activated to contain the distribution of these gases to the desired areas.  Alternately, the medical department can utilize the air processing system to introduce treatments ship-wide for problems resulting from contamination.

All foodstuffs (except live food) can be provided by replicator systems throughout the ship (common dining areas, personal quarters and other areas throughout the vessel.)  Live foods are stored in stasis units in the galley as well as spare Marine hypothermia capsules if available.  The galley is equipped with large refrigerator/freezer units filled with perishable foods for consumption as an alternate to replicated foods.  Two common dining areas exist within the vessel for use by all personnel, while there is one above the galley reserved for officers exclusively.

As a backup to the replicator system, there is a network of water lines running throughout the ship to supply drinking water to the crew.  All quarters are equipped with a sink unit.  There are six processing stations throughout the vessel to recover wastewater and restore it to a drinkable condition.  Each station is equipped with three processing units that remove foreign matter and inject nutrient supplements.  Each station is equipped with a storage tank holding 4000 liters of water.

One of the issues facing those involved in space travel from the beginning of outward expansion was the matter of the loss of gravity once leaving the home world.  Personnel only going into orbit for short periods of time made due in the null-gravity experienced in orbital altitudes.  After the first few missions conducted deeper into space, the deterioration of the health of personnel experiencing prolonged null-gravity brought about a desire to try to duplicate the gravitational and magnetic fields of Qo'noS for those in deep space needed to maintain health and well-being.  Special-purpose magnetic field generators began to be installed aboard space vessels incorporating rotating sections to simulate gravity.  These allowed our early space farers to make their years-long journey with minimal adverse effects on their health, allowing them to remain functional upon reaching their destination.  Problems occurred with vessel systems if they were not sufficiently shielded from the effects of the magnetic fields.  Rotating sections were quickly recognized to be only an interim measure due to the high maintenance requirement of keeping the rotation system operational as well as the unequal level of gravity between the interior and exterior areas of vessels.  Some areas, like shuttle bays and thruster installation points, needed to be kept stationary (relative to the rest of the vessel) to be able to function properly.

Over time, technological evolutions finally allowed the creation of a synthetic gravity field throughout a vessel that could be adjusted, either vessel-wide or in a specific area, to meet the needs of the crew.  The Vor'Cha-DaH'HoS Battlecruiser is equipped with seven networks of synthetic gravity systems that, while generally operating independently of each other, can be interconnected should it be needed to maintain gravity.  Each network is equipped with 110 gravitational field generator units.  There is a degree of overlap between the areas each unit services but it is generally too weak to be noticed and does not affect operations.  Gravity fields are created by channeling a flow of gravitons from the generator unit through the area it services and then back to the generator for redistribution.  Much of the principle behind this system is similar to the operation of the tractor beam devices used on the vessel.

Each generator unit consists of a chamber made of anicium titanide 454, a sealed container 25cams in diameter and 12cams tall.  A stator of thoronium arkenide resides inside the container surrounded by pressurized chrylon gas.  The stator, energized by the vessel's power distribution grid, revolves inside the chamber at a rate over 200,000rpm.  The gravity field that resulted lasted for only a small fraction of second.  Due to this short lifespan, additional units are required to extend the field beyond the range allowed by the first one.  This system also counters the variable gravitational strength between a person's head and foot experienced using the vessel rotation method.

While in operation, the stator should only require a brief power pulse once or twice an hour to maintain its rate of rotation.  Should the pulse not be received, the unit should continue to spin for several hours before coming to a halt.  As the rate of spin decreases, so will the strength of the gravity field it generates.  The generators are protected from minor shocks by a system of sinesoidal ribs on the inside of the anicium titanide chamber.  Stronger shocks would be handled by the ISF system.  Shocks to the stator could have a strong effect on the stator's spin rate, creating a sudden loss of gravity to the area it is servicing.

When engaged in work on the exterior hull area (see HULL section), gravitation field generators nearest the hull exterior will operate in an "overload" condition to maximize the gravity attraction effect.  The power feed to the gravity generators will be increased to intensify the strength of the field generated.  Power pulses will also increase to a rate of once every ten minutes to maintain the higher field output.  Once outside work has been complete the units will be restored to normal operating condition.  They will also be shut down entirely for maintenance at the earliest opportunity; the output of neighboring units will be increased and excess redirected to the area serviced by the unit undergoing maintenance.  Those on the outside surface will feel a gravity strength approximately 30-35% of that felt on the surface of Qo'noS.  As a result, personnel will also utilize gravity boots and tethers to help prevent accidents while working.

Waste management is an area of ship design where engineers from other areas of the Alpha Quadrant have looked to the Klingon Empire to learn their lessons.  Because the Klingon Empire has always functioned in a varying state of war readiness, the handling of resources has become a more important consideration in the minds of our leaders in their planning.  Great efforts are made to minimize the waste of materials that can be put to use.  Much engineering work has been put into developing the most efficient waste-processing equipment possible.  Waste generated aboard ship is generally processed in one of two ways:

Until recent years, greater use of mechanical or chemical processing methodologies has been used in the processing of waste material to minimize the power consumed in the handling of these materials.  Due to improvements in replicator technology, combined with the amount of energy available from the propulsion and other power systems, more use of replicators to break down matter into simpler forms for storage is used in ghop qeylIs.  This also reduces the amount of equipment needed to process waste material, cutting down on the staffing requirements for this department.  In the event that use of the replicator systems must be reduced or suspended, large storage chambers are provided to store the material until it can be processed.  If service is to be suspended for a long period of time, a rationing program may be instituted to cut down on consumption (and therefore waste creation).  If the capacity of these chambers is exceeded before the replicator system can be reactivated, the waste material will be jettisoned into space.  This practice is avoided if at all possible due to the loss of raw material available for future use once the replicators are restored to operation.
