High-capacity land connections taken into
\nuse <\/strong>at the harbour of Hafnarfj\u00f6r\u00f0ur<\/strong><\/h4>\n

Hafnarfj\u00f6r\u00f0ur Harbour<\/a> is the first port in Iceland to offer customers
\nto connect to powerful electrical land connections where ships can get all their power
\nto 1.2 MW. With these new shore connections, ships can receive electricity that is in accordance with
\nthe ship's electrical system, i.e. 400, 440
\nor 690 Volts at 50 or 60 hertz. The first connection is scheduled for Friday, 10 June, when the freezer trawler
\nBaldvin Nj\u00e1lsson GK 400 is connected to 440 volts on 60-amp sockets. The passenger ship Le Bellot, owned by the French company Le Ponant, arrives.
\nby connecting to a new system on Seamen's Day, 12th June this year. It is the first
\na change involving the ship being connected to shore power, and also the first time as a passenger ship
\nis connected to the mainland here. <\/p>\n

Widespread environmental impact<\/strong><\/h4>\n

By docking, ships do not need to burn fossil fuels.
\nat the quay, but it is estimated that around 14 % of a ship's fuel consumption occurs while moored. It is clear that, in general, ships are not yet shore-power-ready. The cost of making them so
\nThe connection speed isn't very high, and hopefully, that will change a lot here.,
\nespecially when conditions in ports generally allow ships to connect
\nelectricity that suits them.<\/p>\n

This summer, the passenger ship Le Bellot is expected to call at the Port of Hafnarfj\u00f6r\u00f0ur around 10 times.
\nIt is estimated that the ship requires about 600 kW, which amounts to around 20,000 kWh per stay.
\nBy using earthed electrical power, greenhouse pollution is reduced at each
\nLe Bellot's inventory of approximately 14,000 kg of carbon dioxide or CO2<\/sub>,
\ni.e. 14 tonnes. Based on 10 indoor events over the summer, the pollution is therefore reduced by 140.
\ntonnes of CO22<\/sub>. This also has a significant impact on air quality, as neither
\nbecomes nitrogen oxide, NOx<\/sub>, nor fixed PM particulate matter10<\/sub>
\nor PM2,5<\/sub> nor any SO soot particlesx<\/sub>. Also, you can have in
\nBear in mind that a shore connection significantly reduces noise from ships.<\/p>\n

The technology behind these powerful landlines<\/strong><\/h4>\n

The technology behind these powerful land connections is based on having
\na high-voltage connector on the ship's side, to which a voltage device is then connected where
\nit is possible to control whether the voltage is 400, 440 or 690 Volts and whether the frequency is
\n50 or 60 rows. Two high-voltage connections are in Hafnarfj\u00f6r\u00f0ur harbour, one at Hvaleyrarbakki and
\nanother on the South Bank. The voltage and frequency equipment is in specially-equipped mobile containers,
\ntwo 10-foot and one 20-foot. To
\nElectric Zinus-type capstan winches are used to bring the power on board.
\nwhich each electrical cable can carry 350 amps.<\/p>\n

The implementation is twofold.<\/strong><\/h4>\n

The implementation of the project was twofold: on the one hand, the high-voltage part, and on the other hand
\nlow-voltage section. Following a tender for the high-voltage section, an agreement was made with the company Orkuvirki, which was responsible for
\nConstruction works on the installation at Hvaleyrarbakka and Su\u00f0urbakka. Design of
\nThe high-voltage section was in the hands of J\u00f3n Bj\u00f6rns Bragason, B.Sc., Electrical Engineer.,
\nMBA. The low-voltage equipment was tendered as a lump sum, based on the specified requirements.
\nR\u00edkiskaup managed the tender in accordance with the specification from J2B Consulting and S\u00e6t\u00e6kni.
\nThe Norwegian company PSW Power and Automation had the lowest bid and was awarded the contract.
\nwith that.<\/p>\n

Environmental policy
\nHafnarfj\u00f6r\u00f0ur Harbour<\/strong><\/h4>\n

The start of this project is the harbour board's approval of an environmental policy and
\naction plan for the harbour by the end of 2019, but preparation of the design and
\nimplementation began in May 2020. The project
\nhas thus taken two years from when preparations began to the completion of the work. The land connection now is the first phase in a larger project which includes further
\nconstruction of land connections in Hafnarfj\u00f6r\u00f0ur harbour and also in Straumsv\u00edk. Estimated
\nthe total cost will be around 600 million kr\u00f3na but the cost of this first
\nThe cost of the phase amounts to approximately 240 million kr\u00f3na. The project management, on behalf of Hafnarfj\u00f6r\u00f0ur Harbour, was handled by S\u00e6t\u00e6kni ehf, Gunnar.
