BRIEF SUMMARY
Project: Augmentation of PHBPL by Laying of new 30" OD Crude Oil Pipeline in Haldia- Barauni section of PHBPL and Conversion of existing 18" OD Haldia-Barauni section (Mainline and Loop line) to Product & Gas Service
Introduction Out of total eleven refineries in the country (Own plus two refineries of subsidiary), IOCL has two refineries located at Haldia and Barauni in the Eastern part of the country and three refineries at Digboi, Guwahati and Bongaigaon in the North Eastern part of the country. The total crude oil requirement of Haldia and Barauni refineries and part requirement of Bongaigaon Refinery is met from the Paradip and Haldia ports, located on the east coast of India. The crude oil received through tankers at Paradip port is transported to these three refineries through Paradip-Haldia- Barauni crude oil Pipeline (PHBPL) of IOCL. Minor crude oil volume is also handled at Haldia for pumping in Haldia-Barauni section of PHBPL (18” Mainline and 18” loop line sections). Barauni- Bongaigaon section of Oil India Limited’s (OIL) Pipeline is utilized for transporting crude oil further from Barauni to Bongaigaon. The present name plate capacity of Haldia, Barauni and Bongaigaon refineries is 7.5 MMTPA, 6.0 MMTPA and 2.35 MMTPA, respectively. These refineries are getting augmented and the total requirement of these refineries will be 20.4 with peak-processing capacity at 22 MMTPA. Whereas, the present capacity of Paradip-Haldia section of PHBPL is 15.2 MMTPA and that of Haldia-Barauni section is 9.2 MMTPA. In view of the projected future crude oil supply requirements of Haldia Barauni and Bongaigaon refineries, capacity augmentation of PHBPL is envisaged as under: a) Augmentation of capacity of Paradip-Haldia (P-H) section from 15.2 to 20.4 MMTPA, which can be increased to 22 MMTPA, when crude oil of lesser viscosity is pumped or through the use of DRA. b) Augmentation of capacity of Haldia-Barauni (H-B) section from 9.2 to 12.4 which can be increased to 14 MMTPA, when crude oil of lesser viscosity is pumped or through the use of DRA. The capacity of this section shall meet the requirement of Barauni Refinery and Bongaigaon Refinery (through Oil India limited (OIL’s) Barauni-Bongaigaon pipeline). For augmenting the capacity of PHBPL, a new 30” crude oil pipeline of 517 kms length is envisaged to be laid from Haldia to Barauni. Upon, commissioning of new 30” crude oil pipeline in Haldia Barauni section, existing 18” crude oil pipelines (mainline and loop line) will be converted to product and gas service, respectively.
Nature of the Project
The proposed pipeline envisages augmentation of existing PHBPL crude oil pipeline from 15.2 to 22 MMTPA). For this, new 30” dia pipeline section from Haldia to Barauni will be laid, originating at Haldia and terminating at Barauni. Further delivery of crude oil to Bongaigaon refinery shall be made through existing OIL’s pipeline. The length of pipeline will be 517 km and its design capacity shall be 14 MMTPA.
The proposed pipeline will pass from number of rivers/canals, Agricultural land etc. There are no rehabilitation and resettlement (R&R) issues.
System Configuration
The facilities to be provided broadly consist of the following:-
Paradip-Haldia section Enhanced throughput of 22 MMTPA would be achieved with the existing facilities in Paradip-Haldia section by utilizing available capacity in the existing system and appropriate DRA dosage. However, additional booster pumps along with a new 42” header is also envisaged to be installed at Paradip
Haldia-Barauni Section Laying of 517 km long 30” OD pipeline from Haldia to Barauni with intermediate pumping station at Bolpur
Existing MLPUs at Haldia and Bolpur would be utilized for achieving the enhanced throughput of 14 MMTPA in Haldia-Barauni section. New booster pumps and modification of header is envisaged at Paradip and Haldia.
Conversion of 18” Crude Oil mainline to Haldia-Barauni Product Pipeline Upon commissioning of 30" OD crude oil pipeline, the existing 18” OD mainline of H-B section of PHBPL is proposed to be converted to product service by providing connectivity to Jasidih ToP through an 18” OD, 12 km long section from a suitable location.
Installation of pumping units at Haldia and suitable modifications in station piping at Haldia and Barauni.
The design capacity of product pipeline shall be 3.4 MMTPA
Isolation of Mainline and loop lines at various locations viz Paradip, Dhumri, Bolpur, Khana and Barauni
Conversion of 18” Crude Oil loopline to Haldia-Barauni Gas Pipeline
Upon commissioning of 30" OD crude oil pipeline, the existing 18” OD loop line of H-B section of PHBPL is proposed to be converted to natural gas service as an extension of IOCL’s approved captive Dhamra-Haldia Refinery Natural Gas pipeline
About 74 km loop line shall be laid along existing 18" OD loop line to cater to location class requirements of gas pipeline.
The design capacity of gas pipeline shall be 2.21 MMSCMD
Suitable modifications in mainline and station piping at Haldia as well as at Barauni for Natural gas injection at Haldia and receipt at Barauni
Replacement of existing valves in mainline as well as stations with API 6D Ball valves, installation of 22 new Sectionalizing Valves in mainline and an intermediate pigging station at about 380 km from Haldia in Bolpur-Barauni section.
Land form, Land use and Land ownership
Pipeline will be laid through acquisition of Right-of use (ROU) and ownership will remain with land owner. Provision of small land acquisition/purchase has been kept only for new RCP/SV stations along the mainline route. Land acquisition/purchase has also been envisaged for Scraper station/ Intermediate Station at Bolpur. The size of proposed plot at Bolpur has been considered as approx. 10 acres.
Mainline Route The proposed Haldia-Barauni product pipeline traverses through West Bengal covering a length of 267 km, through Jharkhand covering a length 120 km and also traverses through Bihar covering length of 148 km. The proposed pipeline alignment generally runs in North West direction.
The pipeline would cross a number of rivers, canals, roads, forest areas and eco-sensitive zone of Ballavpur and Ramnabagan wild life sanctuaries in state of West Bengal. The pipeline is proposed to be installed by Horizontal Directional Drilling (HDD) technique across major perennial rivers / canals, National / State Highways, whereas across minor rivers / canals, pipeline would be laid by submerged crossing method.
The pipeline would be provided with sectionalized valves (SV) at regular intervals all along the pipeline route including providing additional sectionalized valves in one side each major river/ canal crossings with a provision of NRV on the other side. Sectionalized block valves has been considered as per the provisions of OISD-214, which are based on population density index survey along the pipeline route. These valves will generally be motor operated, however, at locations where availability of land would be a constraint. However, provisions of OISD-214 would still be complied.
Project Schedule & Cost Estimates
The project is scheduled to be completed in a period of 36 months from the date of receipt of statutory clearances, which includes six months for conversion of existing 18” crude oil pipelines (mainline and loop line) to product and Gas services. The estimate cost of laying new 30” Haldia Barauni Pipeline including conversion of service of existing lines is Rs 3712 crore.
