近日，由荷兰船舶设计公司科诺国际（Conoship International Projects）开发的新一代柴电动力货船在土耳其Gelibolu造船厂开工建造，预计首制船将于2023年交付。该型杂货船采用柴电推进系统，配备了ConoDuctTail®节能导管以及与其适配的大尺寸螺旋桨，并进行了船体线型的优化。据Conoship公司介绍，该设计方案还为后续安装Econoind VentiFoils®风力辅助推进系统做了预留。根据航线的不同，这一设计将每年减少约10%的燃料消耗和二氧化碳排放。Conoship表示，作为柴油动力船舶，该船的船舶能效设计指数（EEDI）已低于第3阶段的要求，并且为未来燃料的转换作了充分的准备。Conoship董事总经理Jan Jaap Nieuwenhuis表示：“为船舶加装甲醇燃料罐，用甲醇发电机组替换柴油发电机组，或者安装液氢储罐和燃料电池。这些方案的可行性，从概念设计开始时就已经考虑到了。”

    The construction of the next-generation diesel-electric propulsed cargo vessel, developed by Maritime engineering company Conoship International Projects, has kicked off in Turkey. The ceremonial start of the vessel’s first construction took place at the Gelibolu Shipyard, and the vessel is expected to be delivered in 2023. The general cargo vessel has a diesel-electric propulsion system, an enlarged propeller in combination with a ConoDuctTail®, and optimised hull lines. According to Conoship, the design is ready for wind-assisted propulsion, as it is prepared for the placement of Econowind VentiFoils®, which is estimated to reduce fuel consumption and CO2 emissions by about 10% annually, depending on the sailing route. Conoship said that the design is highly future-proof as the Energy Efficiency Design Index (EEDI) of the vessel as calculated as a diesel-driven vessel is already below the phase 3 requirements, and additional elements of the design arrangement facilitate a switch to future fuels. Jan Jaap Nieuwenhuis, Managing Director at Conoship, explained: “For example, take off the generators and replace them with a methanol power generator set, and then put in methanol tanks as well, or take them off completely, and put on liquid hydrogen tanks and fuel cells. All these redesign possibilities were taken into account from the beginning of the conceptual design process.”

propulsion n.推进，推进力 

英/prəˈpʌlʃ(ə)n/  美/prəˈpʌlʃn/

该词的动词形式为propel“推进，驱动”。源自拉丁语propellere，前缀pro-表示前进，pellere表示推动，原词中-ion则是一个常见的名词后缀，表“行为，状态”等。

diesel-electric propulsion system n. 柴电推进系统

Tips：船舶电力推进，通常是以电动机带动螺旋桨推进船舶行驶的工作方式，它是船舶推进方式中的一种。对于能源日益紧张、环境日益恶劣的当今社会，电力推进方式以其环保、节能的技术优势提供了高品质船舶的应用途径。船舶的电力推进装置通常被描述为柴油电力或涡轮电力系统。其特征仅在于原动机的类型，而不涉及电力推进电机的类型。当原动机是柴油发动机时，称为柴油电力推进。
