Safety surveys overview

A survey of 500 plants that have implemented predictive maintenance methods indicates substantial improvements in reliability, availability and operating costs. The successful programs included in the survey include a cross-section of industries and provide an overview of the types of improvements that can be expected. Based on the survey results, major improvements can be achieved in maintenance costs, unscheduled machine failures, repair downtime, spare parts inventory, and both direct and in-direct overtime premiums. In addition, the survey indicated a dramatic improvement in machine life, production, operator safety, product quality and overall profitability. 

This paper gives an overview of risk criteria used in the nuclear industry, European railway and offshore oil and gas industries. A survey of risk criteria has been made within a Nordic project dealing with the use of probabihstic safety criteria for nuclear power plants, see Hohnberg Knochenhauer (2006 and 2008). The project is performed during the period 2005-2009. It was initiated by NKS (Nordic Nuclear Safety Research) and NPSAG (Nordic PSA Group), and has relations to an OECD/NEA WGRisk task on probabilistic safety criteria in the NEA member countries.
