  • Types of pipelines

    Know various types of pipelines and their different usages. Differentiate between pipelines used to transport goods over short and long distances, and understand their respective feeding systems.


  • Secure working area

    Secure the operation site fixing boundaries, restricting access, placing signs and taking other measures in order to guarantee public and staff safety.

  • Use testing equipment

    Use equipment to test performance and operation of machinery.

  • Maintain test equipment

    Maintain equipment used for testing the quality of systems and products.

  • Detect flaws in pipeline infrastructure

    Detect flaws in pipeline infrastructure during construction or over the passage of time. Detect flaws such as construction defects, corrosion, ground movement, hot-tap made by error, and others.

  • Inspect sewers

    Inspect sewage drains in order to detect explosive gases using gas analysis equipment.

  • Examine civil structures

    Perform non-destructive testing on civil structures such as bridges and pipelines in order to find abnormalities or damage.

  • Record test data

    Record data which has been identified specifically during preceding tests in order to verify that outputs of the test produce specific results or to review the reaction of the subject under exceptional or unusual input.

  • Prevent pipeline deterioration

    Ensure the conservation of pipelines by undertaking adequate maintenance of the system and its coating properties. Prevent corrosion formation, leaks, and other problems.

  • Maintain septic tanks

    Maintain effluent sewer systems which use septic tanks to collect sewage, and separate solid waste from it, from residential buildings or organisations. Perform routine maintenance tasks and cleaning duties, identify and repair faults.

  • Assemble manufactured pipeline parts

    Assemble parts and components made for pipelines in companies or sites. Construct pipeline infrastructures or re-assemble parts that were taken out for repair. Use welding equipment and other tools in assembly activities.

  • Repair pipelines

    Conduct maintenance and repair work on pipelines to prevent or remedy damages using, if necessary, remote-controlled robots.

  • Prevent damage to utility infrastructure

    Consult utility companies or plans on the location of any utility infrastructure that may interfere with a project or be damaged by it. Take the necessary steps to avoid damage.

  • Inspect pipelines

    Walk flow lines to identify damage or leaks; use electronic detection equipment and conduct visual inspections.

  • Use pipeline video equipment

    Handle movable video cameras which visually inspect sewerage systems and pipelines. This camera is attached via a long cable entwined upon a winch. Analyse the footage to see if any repair or maintenance is needed.

  • Test sensors

    Test sensors using appropriate equipment. Gather and analyse data. Monitor and evaluate system performance and take action if needed.

  • Maintain records of maintenance interventions

    Keep written records of all repairs and maintenance interventions undertaken, including information on the parts and materials used, etc.

  • Recognise signs of corrosion

    Recognise the symptoms of metal showing oxidation reactions with the environment resulting in rusting, copper pitting, stress cracking, and others, and estimate the rate of corrosion.

  • Supervise sewerage systems construction

    Supervise the implementation of correct sewerage system plans and methods during construction, installation, and maintenance of sewerage systems to ensure conformity to the approved plans, and the safety of operations.

  • Follow health and safety procedures in construction

    Apply the relevant health and safety procedures in construction in order to prevent accidents, pollution and other risks.
