ELECTRIC POWER FOR SMALL COMMERCIAL VESSELS
Some of the principal items of electrical engineering that require the understanding of the marine design are reviewed. These are voltage drops in distribution systems, voltage and frequency tolerances under steady and transient conditions, motor control, circuit protection, generator paralleling, and the relative merits of direct and alternating current systems. Emphasis is on systems for the small commercial vessel. Some of the design problems to be faced are also discussed. These are load analysis, circuit protection methods, choice of emergency power source, choice of alternating current versus direct current, and choice of distribution system. Two actual electric plants are described, one an alternating current system, the other direct current, aboard small passenger ferries of near-identical construction. It is seen that prominent features of the designs are dictated by special requirements of the vessel service.
