  • 2. Contents: The authors would like to thank Mr. ANAND KUMAR SINGH (Energy Risk Professional) for his sincere efforts towards guiding them through the project in terms of Project Risk Management. - Abhik Tushar Das / Ajay Cecil 1.

The sole purpose of this report is to demonstrate understanding of concepts learnt in the course titled “Project Management in Oil & Gas”.
  • 3. Project Charter:Trade is an important facet in the economic development of any nation. The ASSOCHAMSTUDY ON PETROLEUM TRADE™ for the period FY 1999-00 to 2006-07 has found thatpetroleum products exported by India have been growing at a whopping rate of 73 per centfor last three years with the value of oil exports expected to surpass its imports in next sixyears. Petroleum is emerging as the largest foreign exchange sector in India with 16.2 percent share petroleum exports are expected to exceed US$ 20 billion in FY07. To facilitatethis trade, it is essential to supplement our ports with custom-bonded storage warehousesto reduce ship turnaround time and help exporters reduce inventories at theirmanufacturing locations thus reducing transaction cost.This project envisages constructing a marine tank farm near the port of NHAVA SHEVA(JNPT) which will cater to the numerous chemical/ petrochemical industries in the MIDC(Maharashtra Industrial Development Corporation) as also to the two PSU refineries (BPCLand HPCL) located at Mumbai. The Marine Tank Farm would be spread over an area of5acres and have a cargo capacity of 100000 kilolitres with a receiving/ discharging capacityof 200 kilolitres per hour (pumping rate). The tanks farm will be designed to storehazardous liquid cargo (Class-A Storage) and will conform to best-in-class safety standards.The tank farm shall have an access from NH4B which is a spur from NH 4 which links four ofthe 10 most populous Indian cities - Mumbai, Pune, Bangalore and Chennai. NH 4constitutes roughly 90% of the Golden Quadrilaterals Mumbai-Chennai segment and hencethe tank farm is strategically connected to highly industrialized cities. The tank farm is alsoin proximity to Mumbai, the financial hub of India and caters to JNPT which is spread over10 square kilometres (2,500 acres) handling bulk consignments of 7.88 million tons perannum. The port handles 65% of Indias container traffic has an average berthing period of37 hours which is considered very long. Hence the tank farm is expected to cater to highbusiness volumes.
  • 4. Project Objectives:The project objectives can be listed as; Project area: 5 acres Project location: Off-NH4B (NHAVA SHEVA Port, JNPT, NaviMumbai) Shell Capacity: 100000 kilolitres Project Type: Turnkey contract Project construction deadline: 36 months Project Cost: US$ 200 millionProject Location: Project Area
  • 5. Technical Details:The technical details for construction can be detailed as;  Material of construction is Mild Steel  Type of Tank: Floating Roof tanks (20 nos)  Diameter of Tanks: 20 meters (largest tank)  Height of Tanks: 12 meters (highest tank)  Tank foundation: Reinforced Concrete piling with Bitumen and sand surfacing  Associated pipelines: 2650 meters (diameter 100mm and 200mm NB)  Material of Storage: Petroleum derivatives (non-reactive)  Design guidelines: OISD-STD-105/ OISD-RP-108/ OISD-STD-110/ OISD-STD-112/ OISD- STD-113/ OISD-STD-114/ OISD-GDN-115/ OISD-STD-117/ OISD-STD-118/ OISD-STD- 119/ OISD-RP-149/ OISD-STD-156/ OISD-GDN-166/ OISD-RP-167  Tank construction method: Jack-up methodTank Foundation Details:

  • 7. Work Breakdown Structure (WBS):Work breakdown structure (WBS), in project management and systems engineering, is adeliverable oriented decomposition of a project into smaller components. It defines andgroups a projects discrete work elements in a way that helps organize and define the totalwork scope of the project.  Preconstruction Activities: 1. Develop Technical Specifications 2. Contractor Solicitation 3. Pre-construction Meetings 4. Acquisition of Permits and Licences 5. Construction Agreements with vendors, suppliers and sub-contractors 6.

  • 17. Conclusion:The tank farm project, which is supposed to be a very lucrative project in terms of futurebusiness prospects, faces immediate project implementation challenges in terms of highrisk of failure. Also the project envisages to be completed in 4months, would face a delay ofa fortnight, where only a remote possibility of completion (6%) within the timeframeannounced by the promoters. Although a detailed cost analysis was not undertaken due toresource constraints, it can be safely concluded that adequate safeguards should beimplemented to mitigate project risks. In case of cost over runs due to delays in projectimplementation, a cost-benefit-analysis should be performed to ascertain the benefits ofemploying more man-hours during for the project vis-a-vis the cost of capital and theopportunity cost of completing the project before time. Contractors can be givencommensurate benefits based on early completion of project.Key Findings:The key findings in the project can be summarized as; 1. Lucrative business prospects 2. Project deadline would be breached by a fortnight (inclusive of holidays) 3. Project risk is high (RCR=0.714) 4. High risk due to critical activities like Piling & Plate Wielding 5. Mitigation required for the above activities which would significantly reduce risk exposure 6. Manpower deployment to increase at the fag-end of the project (phase- 4/5) 7. RFQ/ Tendering process has to be critically monitored for smooth project execution 8. Due to high project risk, equity should be preferred over debt for capital infusion as high cost of capital (debt) could make the project unfeasable
