PROCUREMENT

With regard to procurement we can offer the following advantages and benefits to our clients:

As a local Nigerian company we have well established relationships and subsequent strong buying power with major suppliers:

• Primary/Secondary Plant and Systems - Reyrolle; SEL; ABB; Areva; GE Multilin; RMS; GE Harris; Logica, Electropar etc
• Auxillary equipment - Phoenix contact, ipd, cabac, etc

FACTORY ACCEPTANCE TESTING/SITE ACCEPTANCE TESTING/COMMISSIONING

PPC performs commissioning work using in-house engineers. Our secondary system design engineers produce Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) procedures, as well as commissioning plans which are developed specifically in accordance with the project scope of works as part of the design process.
Factory Acceptance Testing (FAT)
Before equipment is sent to site, a full series of Factory Acceptance Tests (FAT) are conducted and comprehensive FAT documentation is produced. The Factory Acceptance Tests range from general wiring tests through to full functional testing of relays/logic and communications back to a master station simulator. As part of the FAT procedure, the secondary drawings are also revised to factory “As built” prior to issuing for final construction.

Site Acceptance Testing (SAT)
Our engineers lead the testing teams to ensure that the installed equipment meets the design requirements. A full series of Site Acceptance Tests are conducted and comprehensive SAT documentation is produced which is made available to the client prior to energisation of equipment.

PPC has vast experience in the commissioning of HV substations and switchyards including the critical aspects of secondary circuit isolations in existing substations.

CONSTRUCTION

PPC has a site construction management capability, and our resources and expertise in this area will be applied to augment the capability of subcontractors.
PPC uses its in-house project management personnel to ensure that the project works are carried out in line with the design requirements, and delivered to the required quality standards and completed in a timely fashion to meet the project program.

This ensures that we have the required control over on-site processes in order to achieve the required project delivery, installation quality, safety and environmental standards.
