Engine lubrication systems and methods of manufacturing and implementing engine lubrication systems and methods. In particular embodiments, an engine system includes an internal combustion engine lubrication system that utilizes a stacked configuration of a through-bolted engine to pattern around through-bolts and utilizes substantially hollow bulkheads to define a central high-pressure lubrication reservoir that minimizes lube system pressure while maintaining pressure at the extremities of the lubrication circuit. Available space is utilized within the bulkheads to provide a lubrication drainage restriction for reducing lubrication losses at engine shut-down.

A power supply system and method includes a power grid input unit and a diesel generator input unit, separately used for supplying an alternating current to a power supply unit. An automatic transfer switch unit is connected to the power grid input unit and the power supply unit or connected to the diesel generator input unit and the power supply unit, which is used for converting the received alternating current into a direct current. A control unit, which is used for monitoring a current load current and current diesel generator power, determines when to turn off a preset number of power supply loads according to a magnitude relationship between the current diesel generator power and the current load power, as well as according to priority levels of current loads.
