The Alternator Windings Decide Whether the Set Runs on Arrival
On a DG set the most expensive thing to get wrong is the alternator. Its windings and insulation absorb moisture over a humid sea voyage, and a generator that arrives damp fails its insulation-resistance (megger) test and cannot be safely energised until the windings are dried out, a process that can hold up commissioning for weeks. The engine has its own exposures: bare cylinder bores and machined faces flash-rust through the open intake and exhaust, and fluids left in the system weep and corrode. The radiator is a thin-finned core that bends and corrodes, and the control panel, AVR and breakers are moisture- and vibration-sensitive electronics.
BENZ protects the set as a system rather than wrapping a box. The alternator is sealed with desiccant and VCI so the windings ride below roughly 60% relative humidity and arrive dry enough to test and energise without drying out; the engine internals are preserved through the intake and exhaust and fluids drained to transport-safe levels; the radiator is shielded; and the panel is barrier-wrapped. The complete set is secured to its base frame on its true load path and either close-wrapped for full-container shipping or crated on heat-treated, fumigated timber for break-bulk, with the rated lifting points verified.
