Technical principles and process routeThrough the collection of navigation data, environmental data, engine room data, logistics data, etc., a reliable cognition of the ship's navigation data, equipment status and environmental situation is established. Combined with the remote shore-based transmission instructions and the hull's hydrodynamic characteristics, the navigation brain system uses these real ship data to train the route optimization decision-making agent terminal through artificial intelligence methods such as deep reinforcement learning, and outputs the manipulation instructions to guide the operation of the ship's main power unit. These manipulation commands are transmitted to the power optimization unit, which optimizes the power output of the ship's main power unit by combining the device characteristics of the main power unit and the matching characteristics of the ship's propellers. By introducing continuously monitored emission data, the ship's main power unit is further optimized by adjusting the speed control throttle. The emission characteristics of the power plant are established, and the control strategy to realize the optimization of the exhaust emission of the main power plant is established. Finally, the exhaust gas generated by the main power unit is discharged into the exhaust gas purification system of the ship, and the SCR technology is used for deep purification and denitrification, so as to achieve a clean and efficient ship navigation and reduce the air pollution caused by the exhaust gas discharged from the ship.

设备投资本项目以一艘安装10MW主推进柴油发动机的远洋船舶为例,本项目设备投资主要包括两大系统:航行脑系统与低压SCR脱硝系统,主要所需设备列举如申报书全文表1,所有设备的技术寿命为15年,满足绝大多数船舶的全寿期服务需求。根据财务成本管理相关准则,设备折旧年限按照机械设备和电子设备两大类划分,其中机械设备类折旧年限为10年,电子设备的折旧年限为3年。此外,SCR脱硝系统和航行智能脑系统属于核心设备,到期残值率设定为5%,其他设备残值率设定为1%。 所有初始投资都在第一年内完成,且系统加装从加工制造到施工调试完成需要占用船坞改造工期为2个月。对于新造船舶与现有船舶安装费用考虑为80万/10WM。据测算,SCR脱硝系统的初始投资为350万人民币/10WM,可实现的减排效果估算为8kg氮氧化物/MWh。预计设备自重约5吨,尺寸约2.3m×2.3m。烟气检测分析设备是实船重要的排放定量监测手段,采购设备投资为100万/套。航行智能脑系统投资220万元。其他附属设备投资50万元,如管系附件、电气附件等。预计总设备投资合计800万元。

年运行维护费用安装本项目设备的船舶按每年在排放控制区内航行4000小时计,催化剂运行成本费用40元人民币/MWh,每三年需要更换一次催化剂,催化剂加工制造费为40*10*4000/10000 =160万/三年。每年需要投入的尿素原料消耗为220吨/年,船用尿素工业价格按0.25万元/吨计,则尿素运行成本费用为220*0.25 =55万元/年。加装本项目技术装备,目标船的主动力装置预计可以减少氮氧化物排放量为8*10*4000/1000 =320吨/年。基于这些数据获得本项目运行维护费用如申报书全文表2所示。水电费预计10万元每年,人工及管理费预计20万元每年,修理费按设备投资的2%计为12.4万元,设备折旧费用为96.41万元(按财务规定折旧年限计算)。

投资回收期根据本项目初始投资、运行维护费用及附加环保效益分析,分析项目现金流及投资回收期,结果如申报书全文表3所示。假设企业所得税率为25%,且假设所有设备按照直线摊销法,则本项目由于突出的环保效益,在投资的第2.70年即可实现完全回收(静态投资回收期)。

综合效益附加效益主要是减少排放所引起的氮氧化物税费减免经济效益。以北欧航运发达国家挪威补贴政策为例,自2007年起,挪威开始对包括航运、铁路和航空等在内的行业征收氮氧化物税。运营功率超过750 kW的发动机、10 MW以上的锅炉或发生燃烧行为的企业,须缴纳氮氧化物税。2020年的收费标准是每排放1 kg氮氧化物的税费为22.69挪威克朗,相当于17元人民币。所有在挪威领海内排放废气的船舶,无论国籍均需缴纳氮氧化物排放税。以此为附加环保效益测评依据,由设备投资与运行维护费用分析可知,对于10MW的发动机安装本项目系统,预计将取得8kg氮氧化物/MWh的减排量,若按挪威排放控制区内航行4000小时/年,则减免的排放税为8*10*4000*17/10000=544万元/年。由此说明,本项目附加效益显著,通过加装本系统有望获得挪威港口544万元/年的环保补贴。 此外,无论是否在排放控制区内,船舶主动力装置的燃油成本始终是船舶营运的最主要开支。本项目通过航行脑系统优化主动力装置运行效率,将有望为船舶实现能效提升2-5%,这样一项燃油节省,将为降低船舶营运燃油成本支出发挥重要作用。
