A comparison is made between different formats for presenting the results from ship’s hull structure reliability calculations. These include the formats produced by FORM (First Order Reliability Method) and SORM (Second Order Reliability Method), scientific format of the probability of exceedance, reliability as a number between zero and unity and reliability expressed in Bells. After the analysis of the advantages and drawbacks of these methods, the measurement of the ship hull structure reliability in Bells is recommended. This measure is simple in application because it avoids the transformation of PDFs required by FORM or SORM and provides a more convenient presentation of the potential change of structural reliability due to design changes. In addition, direct link between the probability of failure (presented in scientific format) and the reliability presented in Bells allows for easy expression in Bells of the results measured in any other system.
