ABSTRACT
This
research project “Network Analysis as an effective maintenance planning tool”
created a detailed evaluation of strategies and techniques for planning
maintenance activities in the Nigerian process industry, laying focused
emphasis on operations of Warri Refinery and the effectiveness of CPM Network
analysis. A review of previous works related to maintenance planning was
extensively undertaken and findings revealed the extent in which planning
activities has been carried out in the oil and gas downstream sector. The analysis
of related literatures showed that wrench time and equipment reliability were
not considered by previous researchers. Field studies were then carried out to
ascertain how these maintenance indices have been affected by CPM network
planning. With the use of frequency tables, percentages, standard deviation and
simple regression, data collected were analyzed accordingly. Results deduced
from regression analysis and the simple t-test showed that CPM Network tool is
effective in maintenance forecasting and equipment reliability at 5% level of
significance. These analyses identified with great precision, the need for
stakeholders in the process industry to fully inculcate project management and
network planning tools into maintenance operations. Recommendations on
integrating CPM Network tool and SAP ERP for effective maintenance planning was
proffered. The study was concluded by inferring that innovative use of Network
planning tools for maintenance activities would spur rapid growth and development
of the Nigerian oil and gas downstream sector. Further studies on applying
Network Techniques to aspects of maintenance such as Turnaround Maintenance
(TAM), in Reliability Centered Maintenance (RCM) and Capacity Planning were
suggested.
