Real-Time Monitoring of NNPC Pipelines

INTRODUCTION

NNPC face enormous challenges to keep their pipeline assets safe and operational so that they can

fulfill delivery obligations in their downstream sector. Its vast network of pipeline passes through both

densely populated areas as well as rural and remote locations where potential breaks, leaks and

nefarious acts of vandalism threaten to undermine delivery in its value chain. Pipelines face threats of

damage, leaks, lack of adequate maintenance, extreme weather, and natural disasters like flooding and

deliberate attempt to sabotage. hese leaks, damage and breaks cause product loss and flow stoppage.

hey also result to environmental damage.

!or pipelines, detecting these problems can be difficult, as is promptly shutting down the pipeline to

avoid waste and environmental damage. "nowing where the fault is located along the length of the

pipeline can also ensure staff can quickly travel to the problem area and assess the situation.

In the upstream sector, remote real#time solutions, surveillance, monitoring and operation optimi$ation

is gradually taking over as the new standard. %ome of these proven technologies now serve as key

components in the proposed real#time monitoring and surveillance.

his white paper seek to describe the proposed solution which will employ satellite technology and

fibre optic monitoring technology combined with an advanced data collation and analysis software and

an integrated data and visuali$ation platform. his solution would enable NNPC to remotely and

proactively monitor pipelines operations to detect, locate and potentially prevent incidents and&or

resolve them soon enough.

here seem to be an existing technology for pipeline monitoring such as sensors and transducers that

gather necessary data and provide useful information such as pressure drop. 'owever, the system does

not present a network infrastructure and tools necessary to help quickly identify, locate and resolve

problems. !or that reason we are proposing a Pipeline (onitoring %ystem.

he goal of the system is to provide operators with real#time monitoring capabilities and reliable data

to indicate when and where an incident has occurred and a reliable indication of the type of event2 leak,

intentional damage, etc.+ so that problems can be solved quickly or even avoided. It is also important

that such a solution minimi$e the occurrence of false alarms which waste their time and erodes their

confidence in the system. hese capabilities help NNPC to ensure the integrity and up#time of their

pipelines, helping them to improve safety and reliability and also reduce costs.

SOLUTION OVERVIEW

%ensors and ransducers for monitoring pressure, vibration, and temperature will be installed at various

points along the Pipeline. he exact number of sensors and their separation distance will need to be

determined, but the greater the number of sensors, the more accurate any point of failure may be

determined along the length of the pipeline. 5ach %ensor is then connected via a satellite modem back

to our satellite gateway facility in "aduna. !rom here the data is transmitted to the pipeline monitoringcentre. 5ach sensor point may be powered either by a mains power supply, or a solar power panel to

make it totally

s a further option, a fiber optic sensing and communications cable may be laid along thelength of the pipeline to monitor vibrations and enable detection of a wide range of events that may

threaten the pipeline;s integrity, from breaks and leaks to human activity such as footsteps, driving and

digging which may be an indication of malicious activities. he fibre optic system offers continuous

measurement of vibrations regardless of weather and irrespective of location with an accuracy of

approximately *7 metres. he maximum length of each span is 07 "m. %ensors to measure pressure in

the pipeline may also be placed at the end of each span. he use of fibre optics will require a building

and power supply at a maximum separation of *77 "m to house all the equipment.
