A multinational team work together to achieve the feat, equipment operation rate 99.8% ~ ~ NEMO project
Show the true value of described.properties dc cable in Europe
Led the world in terms of climate change countermeasure of Europe has achieved international normalized "electric power trade".The grid is adopted sumitomo electric described.properties of dc cable.
Britain - the Belgian multinational and cable is the purpose of use in Britain and Belgium output of renewable energy, promote carbon dioxide emissions at the same time, between the two countries to realize stable and low-cost power supply.The National Grid company (UK) and ELIA (Belgium), the joint venture company -- -- Nemo Link, sign a contract with sumitomo electric in 2015.Through this project, sumitomo electric industries into Europe and cable market for the first time.After the project total length of about 140 km, is made, in 130 km across the north sea bottom interval "described.properties dc cable laying.Transmission voltage is 400 kv.The refresh when the voltage of the world's highest record, project in February 2019 putting-in-service proactively.This newspaper first special introduced to undertake the project detailed information, this issue will introduce what happened from then to now.
In August 2017, began laying submarine cables from one side of the UK.If can't finish all the process in early 2019, will not be able to smooth putting-in-service proactively.Although the pressing time limit, sumitomo electric engineer sent the "head".As a project team members in the field of power command division of miyazaki billiton zai is one of them.
"There are 5 problem occurred on the cable connection process.But we know the "connect" the process, we know how to deal with and manage if a problem occurs.Our advantage is to accumulate a large number of proprietary technology.But when seemingly going well engineering in ending, but unexpected things happened.To only 3 km distance from Belgium shore, laying project stopped.Cable ashore plan location is a beach.Large cable laying ship sailing in the flat neritic field hard, so we must choose its topography of the corresponding technology and work boat, but it seems to be responsible for the process of the construction method of the construction company has a problem."(miyazaki)
"Cable ashore!?"Coping strategies
The previous patience with you deal with all sorts of problems are different.To explore coping strategies, to report back to the NemoLink company, negotiate with Japanese related department...The process, beach in busy season, coincides with the time limit for a project, which can not carry out the construction, and the rest of the time is less and less.Must be in substation before starting the trial run in early December, complete cable test.The tension in the engineering team.Miyazaki confides: "at that time, I am also very nervous, fear of delay."
"In the end, we arranged other emergency construction company, change the construction of a ship, repeated attempts.Although are treading on thin ice, but we ended up in October 2018 to realize cable ashore."(miyazaki)
But European members of the engineering team for the response.
"Europe is in the contract, the first made representations.Europe there is generally accepted that seems to be happening and negotiation process, it should be shut down, in a sense, delivery delay and helpless.But we attach importance to and Nemo Link company contract, strictly abide by the delivery date and not to cease, and have been trying to solve the problem.In order to the customer, we always think the most prioritize 'to do their work.Perhaps in the eyes of European members, "the customer is supreme of Japan is incredible."(miyazaki)
Miyazaki and others to show outside of Japan team members "sumitomo electric industries".Although the idea and method is different, but the professional consciousness and to the project view is consistent.
"The engineering team in Europe more than 20 people, mainly from Britain and Belgium, there are three, four Japanese people.Engineering is not led by the Japanese command and, precisely, is through the coordination let everyone finish their work in high level.We are very pay attention to this point, and build the trust relationship with each other, finally we also accepted our ideas."(miyazaki)
Let a relationship more strong "transparency" (transparency)
The project's biggest challenge is cable ashore to Belgium, but ELIA CEO Mr Bart ・ and thinks that the end result to ELIA sumitomo electric company more trust.
"In the construction of the project ending when replacement is a huge risk decision-making, but Japan member told us: 'why problem happened and how to deal with now.'"Mr (and)
Nemo Link as Britain and Belgium company joint venture company set up, it is said that the engineering team is selected in consultation, construction of the project and the "described.properties dc cable" compared to a positive attitude towards ELIA company, NationalGrid companies have to zero results in Europe sumitomo electric distrust."Welcome to come to Japan to visit our manufacturing site", the zeal of sumitomo electric proposed to eliminate the "difference".
"The decision to the submarine interval to sumitomo electric is complete, in addition to the technical strength, more important is, if a problem occurs sumitomo electric can keep 'transparency (transparency)', it gave me the bullet."Mr (and)
Show the truth, not whitewash problems, don't exaggerate.And Mr Think these are the final choice of sumitomo electric decisive factor.
"In the manufacturing, transportation, and engineering and so on various scenarios, sumitomo electric maintain a firm attitude.Sumitomo electric还与负责变电所的Siemens公司（德国）进行了深入协作。”（玛士先生）
Results: the operation rate of 99.8%
If is responsible for the high voltage dc cable is sumitomo electric industries, then in charge of dc converter station is Siemens.The two companies to cooperate is the key factor in the success of the project.
With Siemens company as a business head by the department of HVDC YaoErGen ・ Croatia beauty Mr Talked about the project implemented by another results: "is not the only cable connected."
"The project team members from five countries.The differences between Japan and Europe, European countries also have different cultural background.In order to achieve the common goal, we must establish a strong cooperation relationship, the subject lies in how to establish the cooperation relations.Everyone also attaches great importance to work outside of the communication, such as with family go on a weekend trip or dinner together.This is a rare opportunity insight into each other's cultures."Mr (Croatia)
The project's success makes the relationship between the two companies more strong.Today, as partners maintain trust relationship, the two companies still promote the development of new technology, to participate in various global and cable project.
In 2022, through renewable energy power supply in Britain - Belgium international Internet cable and ushered in the four years after the putting-in-service proactively.In offshore wind power continuously improve, in European power infrastructure, and the cable has been occupies the important position.Except for the new crown outbreaks and unable to enter the scene in 2020, sumitomo electric members conducted regularly check carefully.The winter of 2021, Nemo Link, from carmakers ─ ─ "in 2021 the highest operation rate for the past three years, 99.8%!"High operation rate also reflect on the earnings stability.Sumitomo electric的直流XLPE电缆在环境政策领先地区切实发挥出了真正价值。
