(41j) Optimizing Fixed Deluge Fire Systems: Maintaining Reliability and Availability without Increased Costs in Extended-Life and Decommissioned Units.

Extending the operational life of offshore platforms presents challenges in maintaining system integrity and reliability. Decommissioning adds further complexity, with aging fire-suppression pump systems exhibiting reduced capacity and increased risk of failure. This research explores methods to maintain adequate fire suppression capacity. By optimizing the platform's hydraulic balance and isolating obsolete deluge sections, we can reduce the operational demands on existing pumps. This approach leverages readily available resources, such as sprinkler capping, to achieve significant gains in fire protection coverage without substantial capital investment. A case study is presented to validate the practical application of these methods.
