3. Project Charter:
Trade is an important facet in the economic development of any nation. The ASSOCHAM
STUDY ON PETROLEUM TRADE™ for the period FY 1999-00 to 2006-07 has found that
petroleum products exported by India have been growing at a whopping rate of 73 per cent
for last three years with the value of oil exports expected to surpass its imports in next six
years. Petroleum is emerging as the largest foreign exchange sector in India with 16.2 per
cent share petroleum exports are expected to exceed US$ 20 billion in FY07. To facilitate
this trade, it is essential to supplement our ports with custom-bonded storage warehouses
to reduce ship turnaround time and help exporters reduce inventories at their
manufacturing 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 (BPCL
and HPCL) located at Mumbai. The Marine Tank Farm would be spread over an area of
5acres and have a cargo capacity of 100000 kilolitres with a receiving/ discharging capacity
of 200 kilolitres per hour (pumping rate). The tanks farm will be designed to store
hazardous 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 of
the 10 most populous Indian cities - Mumbai, Pune, Bangalore and Chennai. NH 4
constitutes roughly 90% of the Golden Quadrilateral's Mumbai-Chennai segment and hence
the tank farm is strategically connected to highly industrialized cities. The tank farm is also
in proximity to Mumbai, the financial hub of India and caters to JNPT which is spread over
10 square kilometres (2,500 acres) handling bulk consignments of 7.88 million tons per
annum. The port handles 65% of India's container traffic has an average berthing period of
37 hours which is considered very long. Hence the tank farm is expected to cater to high
business volumes.

7. Work Breakdown Structure (WBS):

groups a project's discrete work elements in a way that helps organize and define the total
work scope of the project.

3. Handover to operations
14. Project Risk Management:
Risk likelihood is the probability that a potential risk factor will actually materialize. It is
expressed numerically between:
never happen (0)
will happen (1)

Project Overview:
17. Conclusion:
The tank farm project, which is supposed to be a very lucrative project in terms of future
business prospects, faces immediate project implementation challenges in terms of high
risk of failure. Also the project envisages to be completed in 4months, would face a delay of
a fortnight, where only a remote possibility of completion (6%) within the timeframe
announced by the promoters. Although a detailed cost analysis was not undertaken due to
resource constraints, it can be safely concluded that adequate safeguards should be
implemented to mitigate project risks. In case of cost over runs due to delays in project
implementation, a cost-benefit-analysis should be performed to ascertain the benefits of
employing more man-hours during for the project vis-a-vis the cost of capital and the
opportunity cost of completing the project before time. Contractors can be given
commensurate 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
