Introduction to a condition-based maintenance solution for offshore platforms

Abstract

It is a trend to construct and operate with complex and large-sized offshore platforms. Offshore platforms would be operated for a long time over 20-30 years. Moreover, more costs and efforts are invested in operation and maintenance (O&M) phase than construction phase. Oil majors and operating companies recently focuses on huge costs for operation and maintenance. They would have an interest in efficient operation and appropriate maintenance to ensure facility integrity. A modernized and optimized maintenance methodology would be on the rise to business competitiveness. A Condition-based Maintenance (CBM) is the key solution for these requirements. We define the process of prediction of residual life based on conditions and propose the system configuration of CBM solution. In this paper, we introduce the CBM solution for offshore platforms. CBM would be defined by the maintenance plan that predicts a lifetime of equipments via expert diagnosis with operating conditions and ensures the seamless operation by repairing them before breakdowns or faults. The CBM solution would be a decision-making support solution to preserve facilities before breakdown. It would expertly diagnose equipment states based on data gathered by SCADA system and predict accurately a residual lifetime by measuring and reasoning of deterioration.
