AN IMPLEMENTATION OF A COMPUTER BASED
SEAPORT BILLING SYSTEM
(A CASE STUDY OF
NIGERIAN PORT AUTHORITY LAGOS)
ABSTRACT
Handling
of cargo has been a circular task all these while in our various ports.
And Nigerian Ports Authority (N.P.A) being an organization responsible for
seeing to the affairs of our various sea ports in Nigeria, have worked
endlessly to make sure cargoes are properly handled without much complain of
damage or misplacement.
To ease the operation of cargo handling in our sea ports, researcher took up
this study by critically understanding the work, procedure involved, analysis
of the various steps and at the same time detecting problem in the present
system and designing a new system that has solution to the problem of the
existing system.
The new design is computerized and is subject to modification at any given
time. It also have this interaction feature and accurate in it’s output.
ORGANISATION OF THE

CHAPTER ONE
INTRODUCTION
Nigeria Ports Authority is a government owned organization under the
supervision of the federal Ministry of transport with responsibility of providing
specific ports and labor services for the country’s meantime industry.
One of their numerous duties and major functions is the provision of Cargo
Handling Quays facilities. Right from the inception of this company, the
billing system has been manually processed. The port complex is in the
early stage of computerization and the manual method of preparing customers’
bills are delayed.
A computer-based billing system is necessary for handling and preparing of
accurate bills for customers. The new system will facilitate the prompt
preparation of bills, easy retrieval of information, security to vital
information and resource sharing among the billing department.
1.1
BACKGROUND OF STUDY:
Once Port complex is
located near Port Harcourt, Rivers State of Nigeria, the port is a natural port
and was established about twenty years ago, firstly with the construction and
commissioning of the Federal Lighter Terminal (FLT) in 1982 and later the
Federal Ocean Terminal (FOT) in 1996.
These two terminals
handle lighter (smaller) vessels and ocean-going vessels respectively.
The average draught of FLT is about 5.7m while that of FOT is about 13.0m being
the cheapest in the West and Central African sub-region. In this regard,
the FOT is envisaged to be attiacting more cargo ship and traffic not only as a
transit but also as a transshipment center in the sub-region. It however
did not have any mechanical handling equipment for billing.
The billing system is
presently handling manually by the marketing department of this port. The
marketing department of the port took over the function of revenue billing from
the traffic department in the 80’s. Their main function is to raise
customer’s bills of all statutory charges against port users for the services
rendered to them. These services includes Rental period at the number of
days the consignment in within the port vicinity, NPA shore handling, transfer
service, documentation, terminal delivery value added tax (VAT) and
miscellaneous.
The role at which the
bills are prepared with the increasing number of customer is
insignificant. There are procedural ways in which these bills are being
prepared. They are the provisional bills of vessels, the final bills of
vessels and the miscellaneous bills. A staff has to raise as many bills
as the number of the customer increases: more importantly, delays bring extra
cost on the importer, and this makes the importer feel disappointed when they
come to collect their raised bills.
Hence, a thorough
investigation and analysis of the manual billing method enables me to gain
understanding on the true nature of their problems and design a computerized
seaport billing system that would bring solutions to the problem inherent.
1.2
STATEMENT OF PROBLEM
History has it that
the billing system in Nigeria Port Authority, one port has been plagues by
several factors based on the current manual process by the use of the Draft
import Debit and import Debit Note, these factors includes:
·
Fills and records are not properly kept
·
Errors are easily made and hardly detected
·
A lot of time is wasted to prepare bills
·
Information is not well documented
·
Security of files or document is not granted.
1.3
PURPOSE OF STUDY
The main aim of this
study is to computerize Nigeria Ports Authority, Onne Port billing system in
order to improve their transaction rate of services to their various customers.
1.4
OBJECTIVE OF THE STUDY
The primary aim of
this project research is to develop a computer-based seaport billing system
that will handle the bills raised for various customers specifically in NPA,
Onne Port. A computer –based system can be ‘batched’ or
‘interactive’. A batch processing system is one where transactions are
accumulated into batches of suitable sizes, then each batch is sorted and
processed as a simple unit. Batch processing has a degree of delay.
Interactive systems are those which allow the user to input data in response to
the information displayed on the screen.
This project is concerned with only ever, the researcher touched
all parts of system design that will enhance a computer based billing system in
NPA.
1.5
SIGNIFICANT OF THE STUDY
The need for a study
of this nature can not be over emphasized. It is expected that with the
designed system, one can realize some important effects of the computerized
billing system. Some of the effects are :-
·
The chances of frauds of any kind will be drastically reduced as well as errors
on customer’s bill.
·
The new system saves time and facilitates the prompt raising of bills as delay
brings on extra cost to customers.
·
The information flow is well maintained and it enhances the top management
decision making.
·
The new system ensures ease of processing and hence ensures faster processing
of output on customers waiting to collect theirì¥ÁG personal
property other than animals.
