APPENDIX:

船用燃料消耗量的收集方法

METHODOLOGY FOR COLLECTING DATA ON FUEL

CONSUMPTION

方法 A．燃油舱测量法

Method A: using bunker fuel oil tank monitoring on board

通过量油尺、声呐、自动化系统等，连续测量燃油舱来获取燃油消耗量，从而确定报告期内的船用燃料消耗总量，并按公式（1）计算。

This method is based on fuel tank readings for all fuel tanks on-board. Fuel tank readings shall be carried out by appropriate methods such as automated systems, soundings and dip tapes. The basic expression for this method is defined as：

Q  Q₁ Q₂ Q₃ ......Q_n ........................................... (1) 式中：

Where:

Q₁、Q₂、Q₃——报告期内第 1 次、第 2 次和第 3 次通过燃油舱测量获得的燃油消耗量，单位为吨（t）；

Q₁、Q₂、Q₃ are the consumption volume (tonnes) measured for the first, second and third time using bunker fuel oil tank monitoring on board during the reporting period;

Q_n——报告期内第 n 次燃油舱测量得的燃油消耗量，单位为吨（t）；

Q_n is the consumption volume (tonnes) measured for the Nth time using bunker fuel oil tank monitoring on board during the reporting period;

n——报告期内燃油舱测量总次数。

n is the total times conducting bunker fuel oil tank monitoring during the reporting period. 原则上，应当在每天以及每次加装或驳出燃油时进行燃油舱测量，并在船舶到港或其他可行情况下，对燃油舱测量数据进行校正。如果采用了密度、温度等修正，应当保留证明文件。测量数据概要和燃油消耗记录应当保留在船。

The tank readings will normally occur daily when the ship is at sea and each time the ship is bunkering or de-bunkering. Any corrections, e.g. density, temperature, if applied, should be documented. The summary of monitoring data containing records of measured fuel oil consumption should be available on board. 注：使用气体燃料的船舶不适用该方法。

Note: this method shall not be used when gas is used as a fuel.

方法 B．加油签收单（BDNs）加总法

Method B: BDN and periodic stock-takes of fuel tanks

这种方法是基于加油签收单（BDNs），对报告期内的燃油加装量进行加总，加上前一个报告期的盘存燃油量，再减去燃油驳出量和结转到下一报告期的燃油消耗量，来确定燃油消耗总量，按公式（2）计算。

This method is based on the quantity and type of fuel as defined on the BDN combined with periodic stock-takes of fuel tanks based on tank readings. The fuel at the beginning of the period, plus deliveries, minus fuel available at the end of the period and de-bunkered fuel between the beginning of the period and the end of the period together constitute the fuel consumed over the period. The basic expression for this method is defined as：

Q  Q_b Q_d Q_c Q_e ................................................ (2) 式中：

Where:

Q_b——报告期初的燃油舱存量，单位为吨（t）；

Q_b is the volume of fuel (tonnes) at the beginning of the period;

Q_d——加油签收单（BDNs）记载的加油量，单位为吨（t）；

Q_d is volume of deliveries recorded by the BDNs;

Q_c——油类记录簿记载的燃油驳出量，单位为吨（t）；

Qc is the volume of de-bunkered fuel recorded by the oil record book;

Q_e——报告期末的燃油舱存量，单位为吨（t）。

Q_e is the volume of fuel available at the end of the period. 加油签收单（BDNs）须在船上保存至少 3 年。

The BDN is to be retained on board for three years after the delivery of the bunker fuel and is to be readily available.

为确定舱内燃油余量在报告期前后的差异，应在报告期开始和结束时进行燃油舱测量。任何用于 终区分燃油舱存油量的补充数据应保留书面证明。

The periodic stock-take of fuel tanks on-board is based on fuel tank readings. It uses tank tables relevant to each fuel tank to determine the volume at the time of the fuel tank reading. 燃料驳出量应与油类记录簿中的记载相符。

The amount of any fuel oil offloaded should be based on the records of the ship's oil record book;

如果船舶按航次收集数据，且航次跨越不同报告期的，则所收集的数据应计入航次结束时间所在的报告期。

In the case of a voyage that extends across the data report period, the data should be allocated to the report period in which the voyage finished.

如果船上无加油签收单（BDNs），不适用此方法；如船载货物（如液化天然气）用作燃料时，此方法不能单独使用。

This method shall not be used when BDN are not available on board of ships, especially when cargo is used as a fuel, for example, liquefied natural gas (LNG) boil-off.

方法 C.燃油消耗流量计法

Method C: using flow meters

这种方法基于船舶燃料流量计读数，通过连续读取船舶所有用能设备船用燃料消耗量，对其加总获得报告期内船用燃料消耗总量，按公式（3）计算。

This method determines the annual total amount of fuel oil consumption by measuring fuel oil flows on board by using flow meters. Total fuel oil consumption may be the sum of daily fuel oil consumption data of all relevant fuel oil consuming processes on board measured by flow meters. The basic expression for this method is defined as：

Q  Q_d1Q_d2 Q_d3 ......Q_dn .......................................... (3) 式中：

Where:

Q_d1、Q_d2、Q_d3——报告期内第 1 次、第 2 次和第 3 次使用船舶燃料流量计测得的船用燃料消耗量，单位为吨（t）；

Q_d1、Q_d2、Q_d3 are the volume of fuel monitored using flow meters for the first, second and third time during the reporting period.

Q_dn——报告期内第 n 次使用船舶燃料流量计测得的船用燃料消耗量(t)。

Q_dn is the consumption volume (tonnes) measured for the Nth time using flow meters during the reporting period;

原则上，应在每天以及每次加装或驳出燃油时记录船舶用能设备的流量计读数并计算船用燃料日消耗量，并在船舶到港或其他可行情况下，对流量计测量数据进行校正。

Reading of the flow meters normally should be recorded daily and each time the ship is bunkering or de-bunkering. Any corrections, e.g. arrival at port or other circumstances if applicable, should be documented.

如果某些用能设备未配备船用燃料流量计或所配备的流量计发生故障，应采用其他替代方法进行数据收集。对于所采用的任何替代方法，以及对流量计所进行的校正和保养，应如实记录，并将记录保留在船上。

In case of the breakdown of flow meters, manual tank readings or other alternative methods will be conducted instead. Any alternative methods, corrections or maintenance should be documented, and be available on board.
