ELECTRICAL DRIVE SYSTEM FOR OPERATING A (BARGE-) LIFTING PLATFORM WITH D.C. MACHINES SUPPLIED THROUGH RECTIFIERS

The Seabee type barge-carrier Yulius Fuchik, the first of two sister ships built by Valmet Oy, Helsinki, for the Soviet-owned Banube-Sea-Line can carry 26 barges each weighing 1,300 tonnes, and these are handled by a winch-operated lifting platform at the stern; two barges can be lifted at the same time. The barges and lifting platform are larger than those of the American Seabee ships, and the hoisting and handling gear is of a different type. The electrical equipment for driving the eight winches and operating the platform was developed and supplied by the Author's firm, AEG-Telefunken, working in conjunction with Kone Oy, the main contractors for the complete barge-handling installation. The article describes the electrical installation for the elevator, and in particular the control and regulating arrangements provided to meet the exacting requirements of the installation. There is a pair of winches for each corner of the platform, and each winch is driven by a shunt-wound d.c. motor rated at 88.5 kW at 1,000 rpm, giving a total power of about 700 kW. At least two generators supply the ship's mains during lifting operations; the winch motors have their own controlled rectifiers. After some general information on this installation, including a brief description of its mechanical components, the control and regulation arrangements are described in detail under the main headings: 1. General Layout of System. 2. Operational Requirements. 3. Central Control Unit. 4. Regulating Arrangements for the Electrical Drive Installation (Regulation of Individual Drive--Regulation of a Pair of Winches--Regulation of Complete Installation). 5. Operational Performance of the Drive Installation. Order from BSRA as No. 54,164.
