SCR CONTROLLED ELECTRICAL PROPULSION

Briefly explains an SCR (Silicon Control Rectifier) as it specifically applies to vehicular and passenger ferries, pointing out such advantages as: (a) Increased fuel economy--engines are allowed to run at their peak efficiency. (b) Greatly increased maneuverability--quicker, more finite control of propulsion. (c) Increased engine life--engines run at constant speed and never overload. (d) Quieter operation--engines are acoustically isolated from the vessel's structure. (e) Elimination of vessel downtime due to main engine failure. (f) Multiple vessel function--the vast amount of electricity available onboard can supply large pumps to fight harbor fires or even a small city during a catastrophe. (g) Less pollution--electric power is constant--increased diesel engine efficiency results in less lube oil and fuel oil "blow-by" from the exhaust.
