Fire & Gas Mapping Study for IOCL JNPT Terminal

JNPT Terminal is a marketing terminal at Navi Mumbai by M/S Indian Oil Corporation Limited. This marketing terminal consists of different product tanks such as MS, LSHF HSD, HSD, SKO, ATF and Ethanol tanks. JNPT terminal receives products in pipeline and Loading the products to Tanker truck in Bays.

This Fire & Gas mapping study is carried out to help in decision making process for locating the number of Gas and flame detectors in the facilities. The fire and gas detection systems are provided on installations for prior identification of the risk from the accidental toxic and flammable gas release. The risk from flammable or toxic gas releases or fires can be reduced by early detection and subsequent mitigating actions.

The scope of work includes following activities for Fire and Gas Mapping study for JNPT terminal.

  • The Hydrocarbon products handling areas in the JNPT terminal is covered for the Fire and Gas Mapping Study.
  • The dispersion pattern was analysed to identify the location and mounting height of the detectors. Further, an overall Gas detection layout plan was provided.
  • The F&G Study suggests the location, type and number of detectors that needs to be installed across various units.

The main objectives of the Fire and Gas Mapping study for JNPT Terminal are:

  • Identifying all potential hazards that will lead to flammable gas release or ignition.
  • Determination of the characteristics of the likely gas release by modelling the physical effect and consequently quantifying the extent of hazardous scenario on the project facilities.
  • Proposing new fire and gas detection arrangements.

The risk from a flammable or toxic material release is the combination of the probability of a leak occurring and the potential consequences should the leak occur. In determining the probability of a leak, the type of operation, the operating conditions, and the equipment involved are all considered. In determining the consequences, the material contained, the size of the leak, the proximity of the leak to other equipment or the fence line, and speed with which the leak might be detected without instruments are all considerations.
