Abstract

In order to improve a miner's operational reliability and to lower its loss risk, the flexible hose's form as well as its behaviour have been theoretically and experimentally examined and the loads caused by the flexible hose and acting on the ship and on the miner have been determined. A flexible hose with lifting floats (system 'garland') is proposed as most favourable solution. This system provides that given a great cruising range of the miner the forces acting on the suspension points are very low. Though, due to the lifting floats which have to be attached, there are additional handling problems to cope with. For the test purpose a deep sea crawler was provided and during the vehicle's initial operation its electric, electronic and hydraulic components have been examined under water with regard to their safe function under deep sea pressure conditions. All components have been tested one by one as well as part of the whole system. Also relating to the operational reliability, tests for determining the vehicle's inner running resistance have been conducted. Inner and outer running resistance in combination with the sensoric monitoring are the basic elements of a monitoring system which allows to determine respectively avoid critical operations states for the purpose of precalculations.
