Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 25346-2010 "Procedures and Testing Methods for Fuel Supply and Receipt of Ships". Compared with GB/T 25346-2010, except The main technical changes besides editorial changes are as follows:

---Added the terms and definitions of the gauge point, the total height of the gauge, the gauge before the gauge, the gauge after the gauge, the empty gauge, the actual gauge, the oil mark, and the gas station on the water (see 3.8~3.15);

---Added "Basic Requirements" (see Chapter 4);

---Modified the "required conditions before refueling", divided into four items: documents, fuel, metering, and sampling (see Chapter 5, Chapter 5 of the 2010 edition);

--- Deleted "The safety checklist for ship fuel supply and receiving shall be provided by relevant national authorities" (see 5.1.2 of the 2010 edition), and added safety Full inspection confirmation form (see 5.1.1);

---Modified the "refueling process", divided into measurement transfer procedures, manual gauge measurement, volume flow meter measurement, mass flow meter measurement, automatic Five items including fuel dispenser metering, each of which stipulates the operating procedures and requirements of the refueling process (see Chapter 6, Chapter 6 of the 2010 edition);

---Modified the "test and sign after refueling", and adjusted the corresponding content to "refueling process" (see Chapter 6, Chapter 7 of the 2010 edition);

--- Modified the expression of fueling notarization, revised to "third-party measurement" (see Chapter 7, Chapter 8 of the 2010 edition);

---Added the selection timing of refueling third-party metering (see 7.3);

---Added the safety inspection confirmation form, non-cargo oil tank declaration/measurement form, oil sample label and mass flow meter system lead seal checklist Style (see Appendix B, Appendix E, Appendix G and Appendix L);

---Modified the options for the types of fuel oil supplied in the refueling application confirmation form (see Appendix C, Appendix B of the 2010 edition);

--- Modify the flowmeter reading record column in the measurement confirmation table (see Appendix D, Appendix C of the 2010 edition);

---Modified the oil quality record column in the refueling receipt form, and added the relevant statement of MARPOL Annex VI (see Appendix F, 2010 Version Appendix D);

---Added the methods of oil level measurement, oil temperature measurement, manual gauge oil quantity calculation and volume flow meter oil quantity calculation (see Appendix H, attached Record I, Appendix J and Appendix K).
