EXPERIENCE FROM APPLICATION OF PROBABILISTIC METHODS IN OFFSHORE FIELD ACTIVITIES

Probabilistic methods have for along time been recognised as very valuable tools in the decision making process for design and operation. Over the past five years Saga Petroleum a.s. has implemented and applied probabilistic design methods to improve the decision making process for design as well as being a primary support for rational management decision making. The paper presents four areas where Saga Petroleum a.s. has utilised probabilistic methods: 1) simulations of project economy and associated uncertainties 2) code calibration of the ultimate capacity formulations of the system for a tension leg platform concept 3) examinations of sensitivity and criticality of mispositioning of foundation templates for the tethers and 4) geotechnical analysis of a concrete monotower foundation. The paper demonstrates the advantage of use of probabilistic design methods instead of traditional deterministic methods.
