4 Scope of ship energy consumption data collection

4.1 Ship energy consumption and related data items See Table 1 for ship energy consumption and related data items. Table 1 Ship energy consumption and related data items 4.2 Passenger and cargo loading or converted loading The passenger and cargo load or converted load of a ship is calculated according to the following methods. a) For bulk carriers, gas carriers, tankers, general cargo ships, refrigerated ships, combined ships, ro-ro cargo ships (including ro-ro vehicle carriers) For ro-ro passenger ships, the cargo capacity is the total weight of the cargo carried, and the unit is tons (t); b) For container ships, the cargo capacity is the total weight of the loaded containers, in ton (t); if filling in the total number of loaded containers, the unit is Standard container (TEU); c) For ships carrying mixed containers and other cargo, the cargo capacity is the sum of the total weight of the containers loaded and the total weight of other cargo. The bit is in tons (t); if the actual weight of the container cannot be obtained, it will be converted according to 10t/TEU for the heavy-duty container and 2t/TEU for the empty container; d) For passenger ships (including ro-ro passenger ships), the passenger capacity is the actual number of passengers, or the rated number of passengers. 4.3 Classification of bunker fuels The classification of marine fuel is shown in Table 2.

5 Ship energy consumption and related data collection methods

5.1 Data collection on shipping activities The ship's voyage distance, voyage time, operation time, and passenger and cargo turnover can be reported according to the logbook, engine logbook, bill of lading, manifest, and noon and voyage reports are collected. 5.2 Data collection of marine fuel consumption 5.2.1 General requirements All fuel consumption on board the ship during the reporting period should be collected. If the ship uses multiple fuels, the consumption data of each type of fuel should be collected separately. marine The collection of fuel consumption data mainly has the following methods. a) Fuel tank measurement method, the code is A; b) BDN summation method, the code is B; c) Flow meter method, code is C. Depending on the situation, any one of the above methods can be selected, or multiple methods can be used in combination. In the same reporting period, it is advisable to use the same method to carry out Use fuel consumption data collection; if the data collection method is changed, it should be recorded and explained. 5.2.2 Fuel oil tank measurement method The method of obtaining the daily fuel consumption by manually or automatically measuring the fuel tank by the system, and then counting the total fuel consumption during the reporting period, according to Formula (1) calculation. Q = ∑ i = 1 Qi (1) In the formula. Q---the total amount of fuel consumption during the reporting period, the unit is tons (t); Qi---The fuel consumption obtained based on the i-th measurement during the reporting period, the unit is ton (t), and the value of i is 1, 2, 3,, n. Under normal circumstances, the fuel tank measurement should be carried out daily during the voyage of the ship, and after each fuel bunkering or discharge operation. quantity. A summary of measurement data and a record of fuel consumption should be kept on board. When the ship arrives at the port and other feasible conditions, the measurement data of the fuel tank should be analyzed Make corrections. If corrections such as density and temperature are used, the supporting documents shall be retained. This method is not applicable to ships using gaseous fuels. 5.2.3 Addition method of refueling receipts Based on the amount of fuel oil loaded on the BDN, as well as the amount of fuel oil stored in the fuel tanks at the beginning and end of the reporting period and the amount of fuel oil discharged on board during the reporting period, and then The method of calculating the total fuel consumption during the reporting period shall be calculated according to formula (2). Q = C0 ∑ i = 1 Di -∑ j = 1 B j - C1 (2) In the formula. Q---the total amount of fuel consumption during the reporting period, the unit is tons (t); C0---the amount of oil stored in the fuel tank at the beginning of the reporting period, in tons (t); Di --- The amount of fuel oil added on the i-th BDN during the reporting period, the unit is tons (t), and the value of i is 1, 2, 3,, n; B j --- the amount of fuel oil dumped on board for the jth time recorded in the oil record book during the reporting period, the unit is ton (t), and the value of j is 1, 2, 3,, m; C1---The amount of oil stored in the fuel tank at the end of the reporting period, in tons (t). The oil storage in the fuel tank at the beginning and end of the reporting period shall be measured according to the method described in 5.2.2; any supplements used to correct the fuel consumption Documentary evidence should be retained for the data; BDN should be kept on board for at least three years; this method is not applicable to ships without BDN; use the cargo carried (such as LNG) as fuel cannot use this method alone. 5.2.4 Flow meter method The method of obtaining the daily fuel consumption of the ship based on the readings of the flowmeter on the ship, and then counting the total fuel consumption of the ship during the reporting period, according to Formula (3) calculation. Q = ∑ i = 1 mi j = 1 Qij (3) In the formula. Q---the total fuel consumption during the reporting period, the unit is tons (t); Qij---The fuel consumption of energy-consuming equipment i obtained based on the jth reading during the reporting period, the unit is tons (t). The value of i is 1, 2, 3,, n; j takes the value of 1, 2, 3,, mi. If multiple energy-consuming devices share one flowmeter, Qij is the jth flowmeter based on flowmeter i The fuel consumption of the relevant energy-consuming equipment obtained for the second reading. If some energy-consuming equipment is not equipped with a flow meter or the equipped flow meter fails, other alternative methods should be used for data collection. answer Any alternative methods used, and any calibration and maintenance performed on the flowmeters shall be faithfully recorded, and relevant records shall be kept on board. 5.3 Shore Power Consumption Statistics The shore power consumed by the ship is counted according to the power consumption displayed by the power meter.

6 Data Quality Assurance Plan

The company should formulate a data quality assurance plan for each ship, and designate a special person to be responsible to ensure the integrity and authenticity of the collected data. The data quality assurance plan should at least include the following. a) methods for timely detection of systematic deviations or errors in the data collection process, and corrective procedures; b) measures to reduce random errors in the data collection process; c) measures to avoid duplication or omission of data collection; d) remedial measures for missing data in case of failure of data collection equipment; e) The basis for adopting the established data collection method, and the records and instructions for changing the data collection method, etc.
