Technical Field
The invention relates to fuel oil monitoring, in particular to a remote sensing monitoring system and method for the sulfur content ratio of ship fuel oil.
Background
In 11 months in 2018, a traffic transportation department issues 'notice of implementation scheme of the traffic transportation department about printing ship atmospheric pollutant emission control area', and the emission control area is expanded to inland rivers including inland river navigation water areas and Yangtze river trunk navigation water areas of cities above river level on the basis of ship emission control areas of built Bohai-Hui (Jingjin) water areas, Long triangular water areas and Pearl triangular water areas. The fuel oil for ships with the sulfur content of not more than 0.5% m/m is required to be used when the ships enter the coastal control area from 1 month and 1 day in 2019. Starting 1 month and 1 day in 2020, the ship enters the inland river control area and should use the fuel oil for ship with sulfur content not more than 0.1% m/m
Due to the large price difference between diesel fuels with different sulphur content, it is not practical to expect a shipowner to voluntarily use lower sulphur diesel fuels at higher cost without an effective regulatory approach, and it is critical for the maritime department or the water law enforcement and supervision authorities how to check whether a ship uses lower sulphur oils in the emission control area. The traditional method comprises the steps of checking oil change records in a navigation log, extracting oil samples, detecting and the like, and has the problems of high boarding difficulty and low checking efficiency; and because the suspect ship cannot be locked before the inspection, the inspection has no pertinence, and huge inspection cost waste (few illegal ones) exists.
At present, two methods, namely an unmanned aerial vehicle sniffing method and a shore-based sniffing method, are reported for monitoring the sulfur content of ships. Unmanned aerial vehicle sniffing method adopts unmanned aerial vehicle-mounted electrochemical sensorThe module is used for manually operating the unmanned aerial vehicle to follow the running track of the running ship and measuring the SO discharged by the tail gas of the ship2、CO2、NO2The method needs skilled unmanned aerial vehicle operators and good measuring environment in actual operation, and has high cost, limited use conditions and poor operability; the shore-based sniffing method measures SO in air when a ship passes by installing a traditional air quality automatic monitoring system on the shore where the ship passes by2、CO2、NO2The method is simple to install, but is influenced by factors such as wind speed and wind direction, emission of other moving sources in the environment and the like in measurement, and particularly in inland river control area monitoring, the conditions of missing measurement and even no response often occur.
