Quantitative Risk Assessment (QRA) for Additional Facilities

Ennore LNG Terminal is the first LNG terminal on eastern coast of India. This LNG import terminal is expected to spur industrial development in the area. The re-gasified LNG will be divided to power generation plants, fertilizer plants and other industrial units. The gas is available for City gas distribution including transport sector, commercial sector and for cooking in houses (PNG – Piped Natural Gas).

IndianOil Corporation through its Joint Venture Company, to meet the growing demand for liquefied natural gas, IndianOil LNG Private Limited is in the process of building a liquefied natural gas import terminal of 5 MMTPA capacity (equivalent to around 20 Million Cubic Meter per day) at Kamarajar Port (earlier known as Ennore Port ) in Thiruvallur district at the border of Chennai. Kamarajar Port is all metrological conditions operating port with all the infrastructure facilities like breakwaters, entrance channel, turning basin, modern navigational aids and berthing equipment’s for safe manoeuvering and berthing of cargoes already in place.

This QRA study shall consider the processes and associated equipment corresponding to the additional facilities of Ennore LNG terminal, Chennai.

The additional facilities considered for the study are:

  1. Installation of Minimum Send out Compressor
  2. Truck Loading Facilities for loading of LNG In to Trucks.
  3. Installation of Vapour return line for reloading of ships from the Terminal.

The main objective of this QRA study is to quantify and assess risk from process hazards associated with Additional facilities at  Ennore  LNG  Terminal,  Chennai. In order to meet the objective of assessment, potential scenarios has been identified and assessed and the likelihood and consequences related to potential accidental releases occurring in the facility has presented.
