Fjord Line 通过 Blueflow 节省燃油
挪威轮渡运营商已在其一艘游轮上投资了 Blueflow – 预计将在不到一年的时间内收回投资
Fjord Line 通过在船上实施 Blueflow 节省燃油
早在 2 月份，挪威第二大渡轮运营商 Fjord Line 已在其 M/S Bergensfjord 游轮上投资了能源管理系统 Blueflow。这款系统满足船东要在不到十二个月的时间内就可以收回投资的要求，并支持公司计划扩展到更多的船舶。
M/S Bergensfjord 驶进希茨海尔斯港口，转弯停在码头，那里排列着小汽车和卡车等待上船。此游轮是 Fjord Line 拥有的挪威、瑞典和丹麦之间四条渡轮运营路线之一，每年运送超过 140 万乘客、货物和卡车。
M/S Bergensfjord 和 M/S Stavangerfjord 姊妹船是世界上首款也是最大的仅靠环保天然气航行的游轮。每艘船全年每天航行 21 个小时，因此，即使节省了百分之几的燃油，也将为船东节省大量成本。
对于 Fjord Line，减少对环境的影响至关重要，船东已经采取了许多措施来降低燃油消耗和减少排放。技术总监 Kristoffer Morgenstern 解释说：“过去，我们花费大量时间来挖掘 Excel 工作表中的数据、制作图表，并且已经进行了明显的节能改进，但是我们仍然感到错过了尚未开发的潜力。”
不过，船东没有工具可以向其展示这些举措的效果，正因如此，他们决定实施 Blueflow。现在，该系统可帮助 Fjord Line 识别潜在的节能因素，并且相关人员可立即看到自己的辛苦回报。 “Blueflow 当然不是免费的，但是很不可思议，我们现在可以比较实时数据，可节省大量时间，并且可以根据事实做出决策。”Kristoffer 解释说。
Lowest fuel consumption ever
And it seems that the intuition about an untapped potential was right. In May, M/S Bergensfjord’s fuel consumption reached the lowest level ever. The result was, to some extent, caused by the beneficial weather condition – May 2019 was a windless month, but so was May last year. Still fuel consumption was 6,67% lower in May 2019 than May 2018. “We have aimed at reducing the fuel consumption, but it is the first time ever we have reached this level. It is crazy, and even though the weather has a large impact, the drop in fuel consumption is not solely a result of good weather but also due to the implementation of Blueflow”, Kristoffer says.
Dedication, change of mindset and teamwork
Fjord Line uses Blueflow on the bridge, in the engine room and at the head office but in different ways. Nevertheless, the three works closely together and shares the gained insights.
On the bridge is Senior Captain Jan Richter. He is a pioneer in eco-friendly driving, and he works determinedly with Blueflow to optimise manoeuvring and thereby bring down fuel consumption. Jan has been using the system for some months now, and in his opinion, Blueflow is a real game changer. “We have used a lot of time to locate potential savings which we have succeeded with to a large extent. However, I am convinced that we would have reached the same results way faster if we had Blueflow from the beginning”, the senior captain concludes.
Jan is continuously chasing savings, and he explains that Blueflow has affected his way of sailing. “Blueflow has changed my way of manoeuvring, the way I accelerate and the number of engines I use. The system gives me immediate feedback and shows me where I hit the nail on the head”.
Chief Officer Jonas Munk-Madsen, who also works with Blueflow elaborates: “Blueflow has eliminated a lot of doubt as we now can base decisions on facts instead of gut feelings.”

Saving energy has become a focus point onboard Bergensfjord – not only on the bridge but throughout the whole team, and the staff is alert on optimising the work routines to cut emissions. “With Blueflow, it is easy to show people the result of their effort, and that has changed people’s mindset”, Jan explains. The captain is optimistic for the future and believes that further savings will be found with Blueflow onboard.
In the engine room, Chief Engineer Kim Storgaard also has access to Blueflow, and although he was a bit reluctant from the start, Blueflow has become rather popular with the chief engineer. “Initially, we used another system which solely focused on the main engines. Blueflow receives input from all energy consumers, providing us with a much more varied picture of the fuel consumption”, he explains. Besides lowering the overall fuel consumption, the ambition is to reduce the running hours on the diesel gensets, and that way reduce cost for maintenance.
Not only does Blueflow identify potential energy-saving initiatives, but it can also be used for diagnosing problems and maintenance. The tech superintendent and his team identified a pitch problem on both M/S Bergensfjord and the sister ship M/S Stavangerfjord. Data showed that something happened when the ships are sailing with one engine connected. “It is the propeller and the main engine that cause the problem. We have a pitch trend program, but with Blueflow, we can see both the pitch drive and prove the effect on the economy”, he explains.
MRV reporting made easy
End of April was the deadline to provide the final verified MRV emission report to the European Commission – a task that has taken a lot of time on both the bridge and at Fjord Line’s head office. Up until now, data has been typed into Excel sheets manually, and the shipowner looks forward to saving a lot of time and have automatically reports based on valid data utilising the MRV reporting tool in Blueflow.
It’s a keeper
So far, the results look promising, and Fjord Line already sees a reduction in fuel consumption.
“Even though we only have worked with Blueflow for a short time, we expect to reduce fuel consumption with 2-5 % and that the investment will be paid back in 6-12 months”, Kristoffer explains.
And the company believes that Blueflow will make a difference in helping them reduce their future energy consumption. “We see great potential with Blueflow, and we are planning to install the system on the sister ship M/S Stavangerfjord as well”, Kristoffer concludes.
Shortly after publishing this article, Fjord Line decided to invest in Blueflow onboard the sister ship M/S Stavangerfjord and the installation was commissioned in September 2019.
