4.6.2 Service and Auxiliary Systems
The service and auxiliary systems were chosen to minimize cost and maintenance by emphasizing the use of
Commercial-Off-The-Shelf (COTS) systems. COTS systems already in use by the Navy are most desirable. Risk
and cost are minimized because these systems are already tested, proven and approved by the Navy.
Tanks for lube oil, fuel oil and waste oil are sized based on power and propulsion requirements. Equipment
capacity and size are based on similar ships. A Reverse Osmosis Distiller (ROD) will produce potable water on
SSG(X). These systems work by pushing heated seawater through a series of membranes that remove salt and other
impurities. The resulting water is as pure as distilled water. Thermal management of all electrical equipment is an
important consideration in the marine environment. Another important system is the air compressors providing
pressurized air to fill the MBTs. SSG(X)’s MBT tanks are capable of blowing three times without having to be
recharged. The main high pressure air tank and compressors fill smaller high pressure bottles located inside each
MBT.
Environmental control equipment is located in the submarine fan room in the AMR. This includes an induction
inlet which can be used to ventilate hull exhaust. This system also includes a CO2 scrubber and CO2/H2 burner.
The main components in the electrical system are the power converters and bus panels. These are specifically
designed to fit the needs of the submarine and meet US Navy Submarine standards. Designing the two components
off of commercially available parts will allow the power converters and bus panels to be upgradeable and repaired at
much lower costs. The electric systems will incorporate automation limiting the demands on the crew to maintain or
supervise the equipment.
