Multi-objective offshore safety system design optimization
journal contribution
posted on 2010-06-24, 13:31 authored by Lisa JacksonLisa Jackson, Jelena RiaukeThe objective of this paper is to present a multi-objective approach to the
design optimization process applied to systems that require a high likelihood of
functioning on demand. In the real world it is common that there are several objectives to
be met, not just maximising the system availability, and hence an approach is required to
deal with these issues. A method is presented that integrates the latest advantages of the
fault tree analysis technique and the binary decision diagram method to model the
availability issue, along with a multi-objective optimization approach (the Improved
Strength Pareto Evolutionary Approach) to cater for meeting the multiple criteria of
assessment. The end product is a mechanism to yield the best design option. The paper
presents the principles of the method and a case study to illustrate how the method is
applied, along with the results produced. The case study relates to a high integrity
protection system of an offshore platform. The optimization criteria involves
unavailability, cost, spurious trip frequency and maintenance down time. Several
enhancements to the optimization strategy to improve the efficiency of the approach are
discussed.
