Problems solved by technology
[0005] The embodiment of the present application provides an EEOI evaluation method and system for port operation tugboats, which solves the existing energy efficiency operation evaluation due to the limitations of the application of the energy efficiency operation index and the special operating characteristics of the port operation tugboats in the prior art. The method is not applicable to the technical problems of port operation tugboats. By constructing the evaluation method of energy efficiency operation index for port operation tugboats, the comprehensive operation index of different operating conditions can be generated, so as to provide more scientific and accurate evaluation guidance for tugboat energy efficiency management.

Embodiment 1
[0032] Such as figure 1 As shown, the embodiment of the application provides a kind of EEOI evaluation method for the energy efficiency operation index EEOI of port-oriented tugboat, wherein, said method comprises:
[0033] Step S100: Obtain a first collection instruction, and the first collection instruction is used to collect data on the operating conditions of the tugboat in the first port, and obtain the first collection data information;
[0034] Specifically, the first port tugboat is a tugboat that performs towing operations within the port, and is mainly used to assist large ships to enter and leave the port, enter and exit the dock, leave the dock, turn around, move berths, and tow barges, etc. Used as a traffic vessel for port personnel and for the delivery of small quantities of goods. According to the first collection instruction, data is collected on the operating conditions of the first port operation tugboat, and the first collection data information is the ope...
Embodiment 2
[0080] Based on the same inventive concept as the EEOI evaluation method of a port-oriented tugboat in the foregoing embodiment, the present invention also provides a kind of EEOI evaluation system for a port-oriented tugboat, such as Figure 8 As shown, the system includes:
[0081] The first obtaining unit 11, the first obtaining unit 11 is used to obtain the first collection instruction, and the first collection instruction is used to carry out data collection to the operating conditions of the tugboat in the first port, and obtain the first collection data information;
[0082] The second obtaining unit 12, the second obtaining unit 12 is used to accumulate the fuel consumption and working time under the first working condition information, and obtain the first accumulated working information;
[0083] The third obtaining unit 13, the third obtaining unit 13 is used to accumulate the fuel consumption and working time under the first working condition information, and obtai...

Abstract
The invention discloses an energy efficiency operation index EEOI evaluation method and system for port tugboats. The method comprises the following steps: obtaining first working condition state information according to first collection data information; accumulating oil consumption and operation time under the first working condition state information to obtain first accumulated working information; inputting the first accumulated working information into an energy efficiency operation index formula, and calculating to obtain a first tug operation index; carrying out average value calculation on the tug operation index to obtain a first comprehensive operation index; performing data fitting on the comprehensive operation indexes in the preset time interval to generate a first index interval curve; and performing energy efficiency management on the first port tugboat according to the first index interval curve. The technical problem that in the prior art, due to the limitation of energy efficiency operation index application and the special operation characteristics of harbor tug, an existing energy efficiency operation evaluation method is not suitable for harbor tug is solved.
Description
technical field [0001] The invention relates to the field of ships, in particular to an EEOI evaluation method and system for port-oriented tugboats. Background technique [0002] With the increasing awareness of environmental protection, the International Maritime Organization has issued a series of regulations and measures in recent years, and issued four technical circulars including the Energy Efficiency Operating Index (EEOI) to regulate the greenhouse of ships. gas emissions. Energy conservation and emission reduction have reached a consensus in the shipping industry, and reducing fuel consumption and operating costs has become a top priority in ship management. [0003] However, in the process of realizing the technical solution of the invention in the embodiment of the present application, the inventor of the present application found that the above-mentioned technology has at least the following technical problems: [0004] Due to the limitations of the applicatio...
