The area where offshore platforms operate has recently spead due to development if the offshore oil drilling and offshore civil engineering technology. This has led to such diverse requirements as the increase of size and the use of platforms under the increasingly severe meteorological conditions. Jacking unit has also come to need a higher jacking capacity, maneuverability and automatic control. So we have undertaken development study on an automatic control system for the tooth and bar jacking unit based upon the experience in constructing and operating SEPs and have recently completed experimental tests yielding satisfactory results. A control console incorporating electric control circuits, a model jacking unit and a model hydraulic unit were prepared. By carrying out a model test of this jacking unit, we have fully confirmed its excellent performance, safety and reliability.
