Air and refrigeration machine Oil Console fire
Process Safety Progress, 2000Co-Authors: P. P. SinghAbstract:An incident due to the ignition of a fire at the top of an Oil Console of air and refrigeration compressors caused the shut down of an ammonia plant for five days. The cause: failure of refrigeration compressor seals resulted in the lowering of the Oil level in the Console. This caused cavitation in the Oil pump suction resulting in high vibration in the pump discharge piping which led to the snapping of a 3/4 inch diameter interconnection line weld joint. Oil splashing from the snapped joint to the nearby steam header with improper insulation caused a serious fire above the Oil Console.

RTSI - Condition-based Maintenance for Oil&Gas system basing on Failure Modes and Effects Analysis
2019 IEEE 5th International forum on Research and Technology for Society and Industry (RTSI), 2019Co-Authors: Lorenzo Ciani, Giulia Guidi, Gabriele PatriziAbstract:Nowadays, the attention on operation and maintenance of gas turbine is growing fast because the component used in Oil&Gas application are forced to endure great stress level and extreme conditions. The optimal maintenance solution in term of cost and effectiveness is represented by condition-based maintenance, that allows to monitor the system under test making a maintenance decision based on the health status of the device. One of the most critical equipment of a gas turbine is the mineral lube Oil Console used to reduce friction and fatigue between moving surfaces. In order to identify the optimal maintenance policies for the Oil Console, a Reliability Centred Maintenance procedure based on a Failure Modes, Effects and Criticality analysis was applied to the system.

RBD Model-Based Approach for Reliability Assessment in Complex Systems
IEEE Systems Journal, 2019Co-Authors: Marcantonio Catelani, Lorenzo Ciani, Matteo VenziAbstract:Nowadays, system reliability performance represents a key issue in any advanced technology application in order to guarantee ambient, personnel, and system safety. The core of this paper is the reliability block diagram (RBD) generation with the aim of providing project engineers a reliability prediction in the early stages of industrial product development. This study is focused on gas turbine auxiliary systems; these systems include both mechanical items (in particular hydraulic devices such as valves, pumps, and filters) and electronic ones (e.g., sensors, instruments, control logic). Such complex structures are decomposed in single blocks and interconnections to establish their mutual relationship and achieve reliability performance of the whole system. The case study is one of the most important gas turbine auxiliary systems, the mineral lube Oil Console. The aim of this paper is to introduce a new approach to assess system reliability prediction in presence of redundant and stand-by architectures; redundancy is widely used in industrial applications since it is one of the best techniques to achieve fault tolerance. The proposed method led to the development of a dedicated software tool RBDesigner that semiautomatically generates a RBD starting from the sketch of thermal-hydraulic systems and provides the most important reliability parameters. The use of the proposed tool allows project engineers to reduce time delivery, reduce time for improvements, achieve reliability targets, and guarantee availability performance to the customers. The strengths of RBDesigner were finally validated by a comparison with other commercial software solutions.

I2MTC - TTH library: A new tool for diagnostic assessment of Oil&Gas applications
2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2015Co-Authors: Marcantonio Catelani, Lorenzo Ciani, Roberto Conti, Enrico Meli, Luca Pugi, Andrea Rindi, Matteo Venzi, Stefano RossinAbstract:The main task of this study is the development of diagnostics techniques in order to achieve both corrective and predictive maintenance methods. The use of simulation tools can drastically increase speed, efficiency and reliability in the design process of safety critical systems. For these reasons, a dedicated tool named TTH Lib was developed and customized for lube Oil plants simulation. The proposed case study is a mineral lube Oil Console and the authors main purpose is to verify the tool capability to simulate a typical flow-pressure transient with fast dynamic evolution and show the great support that this tool can offer to achieve diagnostic parameters in the early stages of product development.
