Tackling marine emissions
The Taiwanese port city of Kaohsiung relies on its marine network to transport machined goods across its bustling harbour, the thirteenth largest in the world. Kaohsiung is typical of many harbour cities in Asia, where diesel ferries are a necessary part of life.
Yet this activity comes at a cost, with emissions from energy intensive ferries and heavy industries contributing to local air pollution. In nearby Hong Kong, air pollution kills an estimated 3,200 people every year.
As part of a wider drive to improve air quality, the Kaohsiung City Government tasked Taiwan’s Ship and Ocean Industries R&D Center (SOIC) with reducing emissions from its ferry fleet.
解决海洋排放问题
台湾港口城市高雄依靠其海上网络将机加工货物运输到其繁华的港口，这是世界第十三大港口。 高雄是亚洲许多港口城市的典型代表，柴油渡轮是生活必需的一部分。
然而，这项活动需要付出代价，能源密集型渡轮和重工业的排放会导致当地的空气污染。 在附近的香港，空气污染每年造成约3,200人死亡。
作为改善空气质量的更广泛动力的一部分，高雄市政府委托台湾船舶和海洋工业研发中心（SOIC）减少其渡轮船队的排放量。
Replacing diesel with electricity
SOIC required an efficient and cost-effective solution for reducing ferry emissions and decided that a hybrid and electric power system was the best solution.
A major challenge for the new system was ensuring that it generated the required power to meet demand. Replicating the electric systems commonly used in large ships was not an option because their bulky AC generation systems are unsuitable for small passenger ferries. SOIC needed a more manageable energy generation system that was smaller, lighter and yet robust.
用电替换柴油
SOIC需要一种有效且经济的解决方案来减少渡轮排放，并决定混合动力和电力系统是最佳解决方案。
新系统面临的主要挑战是确保新系统产生满足需求所需的功率。 复制大型船舶中常用的电力系统不是一种选择，因为它们庞大的交流发电系统不适合小型客轮。 SOIC需要一种更易于管理的能源生成系统，该系统更小，更轻，更强大。
Custom electrification solutions
Danfoss worked with SOIC to electrify a vessel on the popular Cijian Island passenger ferry route that transports eight million passengers every year along the 650 meter route.
Launching from berth every 15 minutes, the 100-tonne, 23 meter-long Ferry Happiness transports 15,000 passengers every day using two 300HP diesel engines.
The Danfoss solution replaces the diesel engines with two Danfoss EM-PMI electric motors that have synchronous reluctance-assisted permanent magnet technology – a smaller and more manageable solution than a diesel engine.
The drive power of the motors was then delivered using Danfoss EC-C1200 converters. One EC-C1200 converter was used as the DCDC-converter to control the discharging and charging of the Lithium Iron Phosphate battery during operation. Another converter was used as the active front end (AFE) to charge the battery directly from the city’s utility grid or from the ferry's existing diesel generators; so the ferry can be charged from the utility grid or can draw backup power from the diesel generators. The ferry's propulsion motors are also driven with separate EC-C1200 converters acting as motor inverters.
To achieve this, a Danfoss EC-C1200 converter was combined with sophisticated software to coordinate power flow; this means the EC-C1200 can perform different power conversion tasks controlled by active load sharing technology from the power management system.
This single-component approach meant it was straightforward to retrofit the existing diesel engines; it reduced the size of the space required by the engine, and simplified spare part management.
定制电气化解决方案
丹佛斯与SOIC合作，在一条受欢迎的Cijian Island客运渡轮航线上为一艘船提供电气化，该航线每年沿着650米的路线运送800万乘客。
这艘100吨，23米长的Ferry Happiness每15分钟从泊位发射一次，每天使用两台300HP柴油发动机运送15,000名乘客。
丹佛斯解决方案用两台采用同步磁阻辅助永磁技术的Danfoss EM-PMI电动机取代柴油发动机 - 这是一种比柴油发动机更小，更易于管理的解决方案。
然后使用Danfoss EC-C1200转换器输送电机的驱动功率。一台EC-C1200转换器用作DCDC转换器，用于控制运行期间磷酸铁锂电池的放电和充电。另一个转换器用作有源前端（AFE），直接从城市的公用电网或渡轮现有的柴油发电机为电池充电;所以渡轮可以从公用电网充电或者可以从柴油发电机获取备用电力。渡轮的推进电机也由独立的EC-C1200转换器驱动，作为电机逆变器。
为实现这一目标，丹佛斯EC-C1200转换器与先进的软件相结合，以协调功率流;这意味着EC-C1200可以执行由电源管理系统中的有源负载共享技术控制的不同电源转换任务。
这种单组件方法意味着可以直接改造现有的柴油发动机;它减少了发动机所需空间的大小，简化了备件管理。
Less fuel, reduced noise, fewer emissions and lower costs
In 2017, Danfoss delivered Asia’s first hybrid electric ferry, Ferry Happiness; and since then, it has become a model of excellence in e-transport in the region.
The new e-ferry is capable of a top speed of nine knots and its Danfoss system ensures pure electric cruising for half the ferry’s operation time. This can easily be higher thanks to fast shore charging.
It is estimated that the electric power will save more than 25,000lt of fuel every year. Lowering diesel consumption also prevents the release of harmful emissions which will help to improve air quality in the region.
To date, the e-ferry has consumed around a third (33%) less fuel since energy now comes from shore power charging; and it is estimated that the fuel saving could be cut by as much as a half in comparison with the original diesel-powered ferry. Other benefits of the hybrid system include reduced operational noise and lower maintenance costs.
Following the success of this project, the Kaohsiung City Government plans to retrofit the rest of its diesel fleet in order to reduce pollution levels around Taiwan’s largest harbour.
Asia’s first hybrid electric ferry captured headlines around the world, especially in marine media: Marine Insight, Marine Link, Ship Technology, Ship & Bunker as well as Business Green, Greenport, Charged EVs and Green Style.
Head of SOIC’s System Development ChihHung Lin says:
“The Kaohsiung ferries are a key part of the public transport, often playing the role that buses do elsewhere. Taiwan’s ‘Harbour Capital’ has long suffered from heavy air pollution and was double Taiwan's national average for carbon dioxide levels a few years ago. In response, the Kaoshiung City Government committed to cleaning up its fleet and is currently considering the possibility of replacing all 11 of its vessels with this new type of e-ferry. All of this has been made possible with the expertise of the Danfoss marine team in delivering custom electric drivetrain solutions.”
Danfoss Mobile Electrification Vice President Kimmo Rauma says:
“After Kaohsiung realised that emissions from its diesel ferry fleet were a major concern for the city, we were pleased to work with SOIC to deliver a unique solution. The expertise of our dedicated marine team has assisted in swapping noisy, dirty and expensive diesel for quieter hybrid electric power, with no compromise on power. We look forward to further collaboration with SOIC to electrify the rest of its fleet and other e-ferry projects across Asia.”
减少燃料，降低噪音，减少排放，降低成本
2017年，丹佛斯推出了亚洲首款混合动力渡轮Ferry Happiness;从那时起，它已成为该地区电子交通卓越的典范。
新的电子渡轮能够以9节的最高速度运行，其丹佛斯系统确保纯电动巡航，使渡轮的运行时间缩短一半。快速岸电充电可以轻松实现这一目标。
据估计，电力每年将节省超过25,000lt的燃料。降低柴油消耗量还可以防止有害排放物的释放，从而有助于改善该地区的空气质量。
到目前为止，由于现在能量来自岸电，因此电子轮渡消耗的燃料减少了约三分之一（33％）;据估计，与原来的柴油动力渡轮相比，节省的燃料可减少一半。混合动力系统的其他优点包括降低运行噪音和降低维护成本。
随着该项目的成功，高雄市政府计划改造其余的柴油车队，以减少台湾最大港口周围的污染程度。
亚洲第一艘混合动力电动轮渡成为全球的头条新闻，尤其是海洋媒体：Marine Insight，Marine Link，Ship Technology，Ship＆Bunker以及Business Green，Greenport，Charged EV和Green Style。
SOIC系统开发负责人ChihHung Lin说：
“高雄渡轮是公共交通工具的重要组成部分，经常扮演公交车在其他地方所做的角色。台湾的“海港之都”长期遭受严重的空气污染，几年前是台湾二氧化碳排放量的两倍。作为回应，高雄市政府承诺清理其船队，目前正在考虑用这种新型电子轮渡替换所有11艘船的可能性。所有这一切都得益于丹佛斯海事团队在提供定制电动传动系统解决方案方面的专业知识。“
丹佛斯移动电气化副总裁Kimmo Rauma说：
“在高雄意识到其柴油轮渡船队的排放是该市的主要关注之后，我们很高兴与SOIC合作提供独特的解决方案。我们专业的海事团队的专业知识有助于更换嘈杂，肮脏和昂贵的柴油，以实现更安静的混合动力电力，同时不会影响电力。我们期待与SOIC进一步合作，为亚洲其他车队和其他电子轮渡项目提供电气化服务。“
