Methodology for Experimental Determination of Local Ice Pressures on Flexible Hull of Platforms and Ships

摘要

The global ice forces on ice-resistant platforms and ships are greatly dependent from distribution of local ice pressures along ice shield. One of the main factors is flexibility of ice shield. The paper presents the calculation and test procedures for local ice pressures evaluation accounting for flexibility of structure in interface zone. The problem of redistribution process and ice force concentration is discussed for its dependence from flexibility of ice shield on water level with application to the ice tests in basin. The calculation-experimental method for calibration system by load balancing to avoid measurement errors was proposed.
