The standards referred to in this section apply to measurement accuracy, or have an influence on the measured system, therefore only minimal reference to design standards is made. The relevant organisations are summarised below : 1.1. DEPARTMENT OF TRADE AND INDUSTRY (OIL AND GAS OFFICE) Abbrev : DTI or DTI (OGO) Website : www.og.dti.gov.uk The DTI Oil & Gas division have issued “Guidance Notes For Petroleum Measurement Under The Petroleum (Production) Regulations, which apply to the British sector. 1.2. INSTITUTE OF PETROLEUM Abbrev : IP Website : www.petroleum.co.uk A number of standards/guidelines are published by the IP which relate to the handling and measurement of Petroleum Products. The Institute of Petroleum maintains a 18 part “Manual of Petroleum Measurement” and 11 of “Petroleum Measurement Papers”. Reference to the manual is made in the following format, “IP part** section **” where “**” will be the numerical reference. The Institute of Petroleum also maintains a “Model Code of Safe Practice in the Petroleum Industry. 1.3. AMERICAN PETROLEUM INSTITUTE Abbrev : API Website : www.api.org The American Petroleum Institute maintains a 21 chapter “Manual of Petroleum Measurement Standards”. Reference to this manual is made in the following format, “API MPM chapter ***” where *** will be the numerical reference.
