Brief Description

  • The Mangala Development Pipeline (MDP) is the world’s longest continuously heated and insulated pipeline and will have access to 75% of India’s refining capacity.
  • The MDP originates from Mangala Processing Terminal (MPT) in the Mangala Oil Field and passes through two states (Rajasthan and Gujarat), eight districts and travels up to ~670 kms before it reaches its end at the coastal location of Bhogat near Jamnagar on the western coast line of India. About 154 km of the pipeline is in Rajasthan and the rest in Gujarat.
  • The MDP is a 24" crude oil pipeline which is using Skin Effect Heat Management System (SEHMS) to ensure that the crude oil remains above the Wax Appearance Temperature (WAT) of 65 Deg C, through the pipeline. It has 8" gas line which feeds gas to all the ~36 Above Ground Installations located at every ~ 18 km distance enroute the pipeline which produces the necessary power to keep the pipeline at the required temperature.
  • In addition, there is an intermediate terminal at Viramgam for storage and further pumping to the coast, including a pigging facility. There are two other pigging stations at Sanchore and Wankaner to insert 'pigs' (pipeline cleaning devices) that are used to clean and inspect the pipeline
