Pipeline Design



    In October 1992, the Ministry of Domestic Trade and Consumer Affairs was given the responsibility of administrating the Petroleum (Safety Measures) Act 1984 and the regulations made thereunder. This act governs the safety of the petroleum industry which encompasses the safety aspect of the transport, storage, handling and utilisation of petroleum equipment/appliances. To ensure the smooth enforcement of this Act, DOSH was entrusted by the ministry to implement one of the regulations under this act, i.e. Petroleum (Safety Measures) (Transport of Petroleum by Pipelines) Regulations 1985.

    This guide is intended to explain the application procedures for permission to install (PTI)/permission to operate (PTO) petroleum pipelines, bulk storage facility and equipment. The applications are classified into four categories;
     i.   Permission to install (PTI) petroleum pipelines
          ii.   Permission to operate (PTO) petroleum pipelines
          iii.   Permission to install (PTI) liquefied petroleum gas (/LPG) storage facility and gas fuel pipeline system to combustors (appliances)
          iv.   Petroleum equipment approval

  •  i.  Petroleum
    Any mineral oil or relative hydrocarbon and natural gas existing in its natural condition and casing head petroleum spirit including bituminous shales and other stratified deposits from which oil can be extracted, including petroleum products.

    ii.  Petroleum Products
    All substances that are derived from petroleum:
    • Methane, ethane, propane, butane or hydrocarbon which may consist of one or more of the above gases either in the form of gas or liquid (e.g.: natural gas and LPG)           
    • Gasoline
    • Naphtha         
    • Reformate           
    • Kerosene           
    • Diesel          
    • Fuel Gas           
    • Base oil        
    • Lubricating oil         
    • Asphalt / Bitumen          
    • Grease and Wax
    iii.  Petroleum Pipelines
    Petroleum pipelines are all parts of those physical facilities through which the petroleum moves in transport including pipes, valves and other appurtenances attached to the pipes, pumps, compressor units, meters, regulators and fabricated assemblies.

    iv.  Bulk Storage Facility
    Liquefied petroleum gas (LPG) storage system from tanks or cylinders (exceeding two 50-kg industrial cylinders)

     v.  Petroleum Equipment
    Petroleum equipment is all parts of those physical facilities attached to the petroleum pipelines such as the valves, meters and regulators.
  • Scope of Application of the Petroleum (Transport by Pipelines) Regulations 1985

    i.     Permission to Install (PTI) and Operate (PTO) Petroleum Pipelines            
    Applications for PTI and PTO should be submitted for:

    a) Pipelines transporting liquefied petroleum between production facilities, tank farms, natural gas processing plants, refineries, service stations, terminals (marine, rail and truck) and other delivery and receiving points.

    b) Pipelines transporting natural gas from the outlet of separators or traps at oil wells until the outlet of the customer's meter set assembly including gas processing plants, and metering and regulating stations. (Installation of pipelines after the city gate station until before the metering and regulating station in the factory is subject to the Gas Supplies Act 1993.)

    All design, fabrication, installation, testing and the safety aspect of the operation and maintenance of pipelines transporting natural gas shall meet the ASME B 31.8 Code of Standards, and ASME B 31.4 Code of Standards for pipelines transporting liquefied petroleum. See Diagram 1.

    ii.     Permission to Install (PTI) Liquefied Petroleum Gas (LPG) Bulk Storage Facility and Gas Fuel Pipeline System to Combustors (Appliances)            
    All substances that are derived from petroleum, i.e.:

    a. Installation of two or more LPG cylinders in factory premises. See Diagram 2.
    b. Installation of two liquid outlet system LPG cylinders in any premises.
    c. Installation of LPG bulk tank (200 kg, 2.5 kL, 10 kL, 60 KL, etc) in any premises. See Diagram 3.
    d. Installation of gas (fuel gas) pipelines in factory premises. See Diagram 4.
    e. Installation of gas (fuel gas) pipelines in power plants and petrochemical plants. See Diagram 1.

    All designs, installation, testing and the safety aspect of the installation of systems a, b, d and d above shall comply with the MS 830 and MS 930 design code.            
    Meanwhile, for the installation of system d, the design code applicable is ASME B 31.1 (installation of gas pipelines in power plant) and ASME B 31.3 (installation pipelines in petrochemical plant).

    iii.     Petroleum Equipment Approval    
    Application for approval of the use of petroleum equipment shall be obtained for all types of valve (e.g. ball valve, check valve, gate valve, meters, regulators, monolithic joints).
  • Applications by hand should be submitted at the Service Counter at Level 3 of the above address.

    The following are forms and supporting documents which need to be submitted with the application:
    1. Permission to install (PTI) petroleum pipeline (TPSP 1)
    2. Permission to operate (PTO) petroleum pipeline (TPSP 2)
    3. Permission to install (PTI) liquefied petroleum gas (LPG) bulk storage facility and fuel gas pipeline (TPSP 3)
    4. Petroleum equipment approval (TPSP 4)
    5. Permission to operate (PTO) liquefied petroleum gas (LPG) bulk storage facility and fuel gas pipeline (TPSP 5)

    Client Charter
    An application submitted with the complete documents will be processed within 15 working days of receipt.
