The assessment method sequentially comprises: collecting operation data under different load conditions based on a shore crane energy-saving operation method to establish a shore crane energy-saving operation energy-consumption analysis model, obtaining the shore crane energy-saving operation energy-consumption analysis model, substituting data acquired in real time in the loading and unloading process performed by a shore crane driver into the energy-saving operation energy-consumption analysis model to obtain real-time energy consumption Ei' , and finally, the shore crane energy consumption Ei' acquired in real time is compared with a threshold set according to Ei. The corresponding system comprises a signal acquisition system, a signal receiving and transmitting system, a data analysis device, an alarm device, a storage device and a display device. According to the assessment method and system, a real-time energy consumption reference value is obtained by calculation according to real-time shore crane energy consumption and operation data acquired by the corresponding assessment system and is compared with the determined energy consumption threshold to figure out a deviation, and an alarm will be given when an operation exceeds the energy consumption threshold, so that quantitative assessment of energy-saving operations performed by shore crane drivers is realized.
