Fire Water Hydraulic Analysis & Adequacy Study at Mathura Refinery | OISD 116 Compliance & Safety Assessment
Fire safety in refineries is a critical aspect of industrial operations, ensuring the protection of personnel, infrastructure, and the environment. The Mathura Refinery, a key unit of Indian Oil Corporation Limited (IOCL), conducted a detailed Fire Water Hydraulic Analysis and Adequacy Study to evaluate and enhance its fire protection system.
Introduction
The Mathura Refinery, part of Indian Oil Corporation Limited (IOCL), is a major industrial hub where maintaining fire safety and protection facilities is crucial. In this regard, a comprehensive Fire Water Hydraulic Analysis and Adequacy Study were carried out to evaluate the existing fire protection systems. The study ensures that fire water infrastructure meets the required safety standards and provides adequate coverage for emergencies. The purpose of this study is to check the adequacy of the existing fire water network, fire water storage, and Pumps of Mathura Refinery inclusive of MJPL and SMPL located in the Refinery premises.
Comprehensive Fire Water Hydraulic Analysis and Adequacy Assessment
- Fire Water Requirements: Calculate fire water requirements at various process units and storage tanks and Hydraulic analysis of existing fire water network considering different combinations of the fire scenarios as per OISD-116 requirement.
- Pipe Size Verification: To check the pipe size of the existing fire water network with the limiting velocity of 5 m/sec in the hydraulic analysis and recommendations for the modification in the form of drawing, if any, to be given.
- HVLRM/ROHVLRM Feed Adequacy: To check the adequacy of FW line header for the feed requirement to HVLRM/ROHVLRM as per their capacity i.e., 1000/2000 GPM or 2000/4000 GPM or more capacity installed in tank farm areas and process units, recommendations for the modification, if any, to be given.
- HVLR Adequacy: To check the adequacy of installed HVLRs and its coverage range, i.e, whether installed or/and are in the process of installation (through e-MOC at MR) are sufficient for firefighting and in case not found sufficient then provide recommendations for the same.
- Pumping Capacity: To check the existing fire water pumping capacity and recommendations for the modification, if any, to be given. And pump performance is tested onsite to ensure the pump is operated as per datasheet without any deterioration.
- Storage Capacity: To check the existing fire water storage capacity and make up water supply for worst case fire scenario and then recommendations for additional storage tanks, if required.
- Foam Monitor Adequacy: To check the existing mobile/fixed foam cum water monitors adequacy and recommend the required modifications, if any.
- Fire Water Ring Analysis: To carry out network analysis of FW ring flushing points and identify locations /areas having turbulence/stagnation and causing deterioration of lines and provide solution thus any additional flushing points.
- Pressure Gauges: Study pressure gauges in FW network and recommend additional PG to meet OISD-116 standard
- OISD-116 Compliance: OISD-116 Gap analysis to be studied and FW shall be maintained at 7 kg/cm2 pressure at the hydraulically remotest point of application at the design flow rate at that point.
- Modelling: Pipenet spray sprinkler Ver 1.11 is used for fire-water network modelling for the entire facility.
- Site visit: During the site visit, the performance of the pump, HVLR, and Header pressure are checked for adequate performance, and recommendations are given based on the field conditions.
- Sprinkler: The Adequacy of installed sprinkler K factor studied based on OISD116.
- Flushing Points: Study flushing points, check their adequacy, and recommend additional numbers if so.
- Hydraulic Summary: Generation of the hydraulic / flow summary indicating flow & pressure/pressure profiles in the lines.
- Equipment Datasheet: Generation of process datasheet for recommended equipment such as Pumps/Tanks / Hydrants / Monitors / Sprinklers / Fire water header, etc.
- Water Demand Calculation: Water demand for the process unit and tank farm area worked out should be based on the latest OISD Std -116.
Fire water adequacy calculation
To provide the results of the fire water hydraulic analysis in compliance with OISD 116 that was performed for adequacy check of the fire water system, which includes fire water pumps capacity, fire water ring main and headers size, sprinklers, hydrant, monitor’s etc. Also identifies the changes required in the fire water system to achieve compliance to the applicable latest statutory code, i.e., OISD 116.
