Instrumentation:

Skilled technicians and well experienced engineers are prime requisite in successful installation of process instruments.
ABC CONTRACTING has such personnel along with latest testing equipment’s for installation of central control room, field mounted instruments, trunking, cabling/wiring, termination and tagging, piping and tubing for air supply and signal, loop checking & hooking up, testing, calibration etc.
Appropriate methods of installation are selected for all installation works with proper HSE Plan and QA/QC procedure as follows:

ABC CONTRACTING’s HSE Plan

ABC CONTRACTING prepares project specific HSE plan and per client’s guidelines and standard procedure to achieve a target for zero fatality, loss time, accidents, fire and environmental hazards.
Basic PPE requirements of hard hat, safety shoes and goggles are provided to every worker.
Workers shall be provided with safety orientation to follow safety plan for emergency situation, especially in hazardous location.

Safety shall be the responsibility of the safety officer/supervisor who will also coordinate with client’s safety inspector for guidance.

QA/QC engineer supervises quality conformance in coordination with client’s quality inspector.

Materials and workmanship are inspected for conformity at different stages for conformity and NCs are reported f or remedy. Documents on equipment calibration, factory test certifications, site test and inspection reports shall be submitted with “AS BUILT DOCUMENTS” Equipment must safely be moved from delivery point to final location, so as well as Electrical fitting skills; our teams are trained in slinging/ rigging techniques, to ensure the safe movement of such.

Our personnel are experienced with most manufacturers, so whatever type & model of
equipment, we can install to the prescribed standards.
Cable Installation & Jointing:
ABC CONTRACTING specializes in cabling associated with electrical distribution systems.
• Cable Installation up to 66 KV
• Cable jointing up to 33 KV
• Cable containment systems
• Pilots & Communication cables associated with MV /HV Systems
• Low voltage works

Testing & Commissioning:

ABC CONTRACTING has technocrats, equipment and knowhow for all pre-commissioning and routine testing of installed equipment /instruments, switchgears, control and automation system etc.

All circuitry and functionality tests are carried out.

Utilizing our experienced site engineering staff, ABC CONTRACTING offers a competent ‘hands on’ test & commissioning service.
Testing & commissioning is probably the most fundamental part of any project. It is usually the last item on agenda & is the final proving, prior to handover to the client.

It is a demonstration, that the design intent, has successfully progressed, from paper through to reality & that the equipment & integrated schemes, safely operate as intended.
Both old & new equipment needs testing to provide client assurance that when there is a fault, not only will it clear safely, but also the equipment can contain it.

We are capable of carrying out most testing requirements.
Electrical tests can be classified as; Development tests, Type tests, Routine tests, Reliability tests, Commissioning tests. Reliability & Commissioning tests are the site tests & performed after installation of new electrical systems.

Transformers:

We can perform the following tests for transformers.

• Transformer turns ratio test (TTR)
• Transformer winding resistance
• Dissipation factor
• Insulation resistance
• Short circuit impedance test
• Pressure test
• All test for auxiliaries of transformer
