Chapter 1 PUMPING INSTALLATION
d) Generating Set
For reliable operation, sometimes generating set is installed to provide back-up electrical power
supply in the event of TNB outage. Depending on the severity of the consequences, generating set
is provided mainly for flood mitigation project. Compliance to Jabatan Alam Sekitar requirement is
warranted for the installation of the generating set. Chargeman of the appropriate grade should be
assigned to look after the gen-set operation.
1.14 INSTALLATION WORKS
Installation works needs to be treated with care as equipment damage, malfunction and operating
problems would result if it were not properly installed. Ensure that method statement, which details
how the work is to be done, is readily available and is being adhered accordingly. Assign skilled and
trained craftsman, equip with adequate and proper tools and equipment, and maintain good current
engineering practices in the execution of the work. Ensure that safety precautions are being
implemented and safety rules are being closely observed.
1.15 TESTING AND COMMISSIONING OF PUMPING SYSTEM
Plants and equipment are subject to testing and commissioning before being turned over to the user.
The purpose of the testing and commissioning is to make sure that all equipment and systems not
only are functional and operational but also meet the performance requirements. Testing should be
properly planned and executed in order to avoid unnecessary delay at site. All parties involved shall
be closely coordinated, and systematic approach to the testing shall be adapted with clear written
instructions and test records.
Pre-start Checks
To begin with, inspect the equipment in accordance with the manufacturer’s submittals to confirm
correct equipment is installed. The inspection team comprising all the related parties shall verify the
proper installation, and supervise any adjustments and installation checks. Having satisfied with the
equipment installation status, an official report shall be accompanied certifying that the equipment is
properly installed and is ready to operate.
Electrical Systems – Energizing
Upon completion of the pre-start checks above, conduct a thorough and complete examination of the
electrical system before start-up the system. The electrical system including all electrical components
are checked, adjusted and tested accordingly, and all protective devices are calibrated with the
recommended settings. It is important that all electrical checks be conducted in the presence of
qualified and competent electrical inspectors. Turn on the power for the electrical system as soon as
all the necessary electrical checks are fulfilled. A full test report of the above-mentioned electrical
checks/test is prepared.
Equipment Start-up
Upon completion of the electrical checks above, the whole plant is then scheduled for start-up. The
whole system will be put on operational checks to ensure that it is fully functional and operational
without any major problems. Monitor the running conditions of the equipment during the test run,
adjust and rectify faults and malfunctions encountered.
