To better understand issues relating to product loss, PESAMP also conducted visits to the following:


14th February 2017

SENSE SERVICES SDN BHD – Negeri Sembilan

 

 

  • responsible for the calibration of most underground tanks

  • road tanker calibration mainly for southern region

  • calibration of depot master meter

  • main business is upstream

During the visit, we were brief on the operating procedure for underground tank calibration (attachment link).

The team also shared ways in which ullege marker can be tampered and manipulated.

We were also invited to witness a road tanker calibration that was in process at the time.

 

Example of ullege marker which can be adjusted even though both seal still intact

Example of a fake ‘welded bolt’ which can be adjusted

Example of blank calibration plate

Master meter used to dispense water for calibration purpose

Seal use by OGA which is loop around the manhole collar to make it harder to tamper with




Water storage tanks

Prover tanks

Calibration table which is normally issued 3-4 hours after the calibration process

NATIONAL METROLOGY INSTITUTE of MALAYSIA (NMIM) – Sepang

www.nmim.gov.my

Fruitful discussion with Dr. Osman Zakaria (Senior Director of NMIM) and Dr. Abdul Rahman Mohamed (Deputy Director Flow Group)

  

Our National Metrology Institute of Malaysia is under SIRIM and is responsible for:

 

Roles of NMIM relevant to our industry:

  1. Provide traceability using API standards for master meter and prover tank calibration. Audit carried out once a year.

  2. T-Ruler calibration

  3. NMIM, KPDNKK and MCM have meetings every couple of months to solve any problem that may arise.

 

Key notes from the discussion:

  • Proposal by Metrology Corporation Malaysia (MCM) to conduct road tanker calibration once every 3 years instead of 5 years currently.

Action plan:

PESAMP through PDAM will write in to support this proposal

  • MCM was setup in 2005 and till now do not possess any standard operating procedure (SOP) or official guidelines on road tanker calibration. They do however have an internal memo/circular which cannot be shared.

     

    Action plan:

     

    PESAMP through PDAM will write in to KPDNKK to initiate a proper guideline/SOP to be establish which will facilitate standardization, traceability and accountability with regards to road tanker calibration done nationwide.
