Abstract

A risk analysis study was carried out to analyse the conceptual design of a subsea system for the Albacora’s field. Albacora is an oil field located on the continental shelf off the coast of Brazil. The project is being conducted by Petroleo Brasileiro SA- PETROBRAS, owners of the field. Because subsea systems consists of several identical components and the environmental conditions are quite hostile, a risk analysis study of subsea systems should consider the possibility of the occurrence of common causes. In this paper, a model to assess the effects of common mode failure on subsea systems is suggested. Two other models are also used in the analysis: The Marshal-Olkin model and the model suggested by Henley and Kumamoto. The results of the application of these models on the conceptual design of the Template-Manifold of Albacora are shown. Some mathematical approximations which allow a general and easy estimation of the effects of common cause failures are suggested.
