AN EXAMPLE OF LARGE SCALE STRUCTURAL ANALYSIS. COMPARISON BETWEEN FINITE ELEMENT CALCULATION AND FULL SCALE MEASUREMENTS ON THE OIL TANKER ESSO NORWAY

The paper summarizes a linear elastic and static seven level superelement detailed stress analysis of the 190,000 tons dwt oil tanker ESSO NORWAY on which full scale measurements have been carried out. The analysis extends over 3 cargo tank lengths and half the vessel breadth involving about 240,000 degrees-of-freedom and 145,000 basic elements. The agreement between calculated and measured response is very good. This application shows that the required man and computer time is reduced drastically compared to standard FEM programs. Thus the multilevel superelement technique and automatic data generation as realized in SESAM-69 allows large scale detail analyses to be undertaken within reasonable time and at reasonable cost.
