The primary aim of the study is to optimise depot storage
capacity and performance by aligning gasoline supply with distribution
requirements. This study was conducted for one of the Nigerian National
Petroleum Corporation (refiner) depots supplied by a multi-product (gasoline,
diesel and kerosene) pipeline. The depot is supplied by a six-inch
multi-product (gasoline, diesel and kerosene) pipeline at 82 m3/hour and
loading/distribution of 100 m3/hour per arm inside the depot.
The Nigerian National Petroleum Corporation, a refiner, owns
and operates a petroleum products pipeline network connected to its 21 storage
depots across Nigeria. These storage depots are supplied by a multi-product
(gasoline, diesel and kerosene) pipeline network. Since the early 1990s, as
gasoline demand increased, the entire supply/distribution chain appeared
inadequate. The primary aim of the study is to optimise depot storage capacity
and performance by aligning gasoline supply with distribution requirements.
This study was conducted for one of the Nigerian National Petroleum Corporation
(refiner) depots supplied by a multi-product (gasoline, diesel and kerosene)
pipeline. The depot is supplied by a six-inch multi-product (gasoline, diesel
and kerosene) pipeline at 82 m3/hour and loading/distribution of 100 m3/hour
per arm inside the depot. Distribution/loading facility designed for two arms
each for gasoline, kerosene and diesel (or 33.33% for each product), whereas
gasoline storage capacity is 55%, diesel, 33%, kerosene 11%, and slops, 1% of
the total depot capacity. The design supply to distribution chain capacity
ratio showed a mismatch, which in actual operation becomes 2:1. The above
design created a ullage problem at sustained supplies, gross under-utilisation
of supply chain infrastructures and poor operational performance. After a
technical evaluation, a section of the depot storage to loading pipeline
network was re-designed and modified to enable product supply capacity to match
loading, and minimise storage. Hence, the gasoline loading became 66.67%,
kerosene and diesel, each of 16.67%, increasing the actual supply to
distribution chain capacity ratio from 2:1 to 2:2 (and when required, can be
maximised to 2:3), thereby correcting the apparent mismatch between the supply
and distribution chain capacities. Findings showed significant improvement in
pipeline transportation scheduling, depot stock and overall product
distribution. The modification has enabled the refiner to increase depot and
upstream supply chain utilisation.
