The invention discloses a ship bottom coefficient evaluation method and a storage medium. The method comprises the following steps: respectively acquiring navigation data of a target ship in a reference leg and a target leg; respectively acquiring navigation data of other ships in the reference leg and the non-reference leg; the navigation data comprises sea condition data and control data; expanding the navigation data of the target ship in the reference leg based on the navigation data of other ships in the reference leg to obtain a first training sample set; expanding the navigation data of the target ship in the target leg based on the navigation data of other ships in the non-reference leg to obtain a second training sample set; training a first energy consumption prediction model based on the first training sample set; training a second energy consumption prediction model based on the second training sample set; and based on the first energy consumption prediction model and the second energy consumption prediction model, respectively predicting first energy consumption and second energy consumption of the target ship under the standard sea condition and the control data, and based on the first energy consumption and the second energy consumption, obtaining the ship sewage bottom coefficient.
一种船舶污底系数评估方法和存储介质,方法包括:分别获取目标船舶在基准航段和目标航段的航行数据;分别获取其他船舶在基准航段和非基准航段的航行数据;所述航行数据包括海况数据和操控数据;基于其他船舶在基准航段的航行数据对目标船舶在基准航段的航行数据进行扩充得到第一训练样本集;基于其他船舶在非基准航段的航行数据对目标船舶在目标航段的航行数据进行扩充得到第二训练样本集;基于所述第一训练样本集训练第一能耗预测模型;基于所述第二训练样本集训练第二能耗预测模型;基于第一能耗预测模型和第二能耗预测模型分别预测目标船舶在标准海况和操控数据下的第一能耗和第二能耗,基于所述第一能耗和第二能耗得到船舶污底系数。
