CPS INSTALLATIONS

TOOLBOX OF TECHNOLOGIES
The staff of CENA Technical are well qualified, have considerable practical and theoretical experience and have a professional approach to problem solving. Using our Toolbox TM approach, we use the appropriate technique, or combination of techniques to solve client problems. We do not rely on any particular type or kind of equipment and this makes our solutions to problems unbiased, technically sound and above all, in the best interests of our clients. We are specialists in assessing the condition of ageing pipeline networks and can carry out internal and external inspection of pipelines, evaluate and design Cathodic Protection Systems, assess the effects of microbial and provide an integrity assessment of pipeline of any length and size.

CENA has a variety of techniques to carry out our engineering investigations and constructions. This toolbox is constantly upgraded as required and, if necessary, development work will be carried out by us to adapt or modify existing techniques or methodologies.

CENA has installed all types of Cathodic Protection Systems through Swamp and land areas of Nigeria. These systems include deep anode systems, augured and horizontal conventional groundbeds, distributed impressed current and sacrificial systems. Our construction crews have a vast knowledge of Cathodic Protection Systems installations. They are trained not only in the physical application, but also on the theory of how the systems work. This practical hands-on knowledge of Cathodic Protection Systems allows us to greatly improve the quality of work we can provide you. Our construction crews are also certified for the installation of 'Clock Spring' materials in the repair of localized corrosion pitting on pipelines.


GARDNER-DENVER 2000 DRILLING RIG
CENA Technical uses model 2000 which is design to cover a wide field of operation to a recommended depth of 2,000 feet and for casing the wells.
CPS DEEPWELL GROUNDBED.
A completed Cathodic Protection Deepwell Groundbed Security Pit with cover. Galvanised wire fencing was carried out to safe gaurd installation.
POTENTIAL SURVEY
Full maintenance and upkeep of Cathodic Protection System. For example, regular visits (1 or 2 per month) are undertaken to measure pipe potentials and examine the rectifiers. Failed components are replace and reports issued regularly (i.e. Generally monthly).
CADWELDING OF CABLES TO PIPE
We carry out cadwelding, pinbrazing and also stud/plate welding of pipelines, flowlines, tanks and other steel structures to enable cathodic protection hook up.
INSTALLATION OF NEGATIVE JUNCTION BOX.
We manufacture,supply and Install a wide range of negative and positive junction boxes. Ranging from 1-way to 15-ways klippon boxes.
INSTALLATION OF SURGE DIVERTERS/EARTHING
We help our clients in addressing the problems associated with damage of equipment due to over voltage and current surges, lighting, Interference and potential balancing.
COATING REPAIRS
We carry out coating evaluation in order to assess coating defects on pipelines and other coated steel structures so as to repair them.
