NKT – NKT Victoria ready to operate on biofuel
NKT has certified its cable-laying Vessel NKT Victoria to use biofuels such as hydrotreated vegetable oil (HVO) significantly reducing the carbon footprint from her operations.
As one of the first companies in the power cable industry, NKT has certified its cable-laying vessel NKT Victoria to be able to operate on HVO. The certification allows NKT to reduce the carbon footprint from the vessels fuel consumption with more than 98%* as a significant contribution to the company’s decarbonization journey.
– With the biofuel certification of NKT Victoria, we once again show our sustainability commitment as a leading company in the industry. This will lead to significant reductions in the carbon emission from our offshore operations and is a key element in our reaching science-based decarbonization targets. Operating on biofuel also allows us to continue to meet our customer’s increasing expectations for low-carbon operations, says Claes Westerlind, President and CEO of NKT.
In September 2023, the Science Based Target initiative (SBTi) validated NKT’s short-term decarbonization targets. The HVO certification of NKT Victoria is an important step towards achieving the SBTi-approved target of reducing scope 1 and 2 by 90% in 2030 compared to 2019. Biofuel is a diesel-like fuel that is made from renewable waste without the use of fossil resources.
NKT Victoria was inaugurated in 2017 and is one of the world’s most advanced and fuel-efficient, cable-laying vessels. She is capable of simultaneous dual HVDC and fibre-optic cable-laying, HVAC and deep-sea installation with a high-capacity tensioning system. With the move to biofuel, NKT Victoria strengthens her position as one of the most energy-efficient cable-laying vessels in the industry.
The biofuel certification of NKT Victoria was conducted by DNV.

EMR Additional Notes:
- Biomass:
- Biomass is renewable organic material that comes from plants and animals. Biomass contains stored chemical energy from the sun that is produced by plants through photosynthesis.
- Biomass is a clean, renewable energy source. Its initial energy comes from the sun, and plants or algae biomass can regrow in a relatively short amount of time. Trees, crops, and municipal solid waste are consistently available and can be managed sustainably.
- Bioenergy:
- It is a form of renewable energy that is derived from recently living organic materials known as biomass, which can be used to produce transportation fuels, heat, electricity, and products.
- Bioenergy is renewable energy produced from organic matter (called “biomass”) such as plants, which contain energy from sunlight stored as chemical energy. Bioenergy producers can convert this energy into liquid transportation fuel—called “biofuel”—through a chemical conversion process at a biorefinery.
- Types of bioenergy include biogas, bioethanol, and biodiesel which may be sourced from plants (corn, sugarcane), wood, agricultural wastes, and bagasse. Bioenergy is considered renewable because its source is inexhaustible, as plants obtain their energy from the sun through photosynthesis which can be replenished.
- Biofuel:
- Any fuel that is derived from biomass—that is, plant or algae material or animal waste. Since such feedstock material can be replenished readily, biofuel is considered to be a source of renewable energy, unlike fossil fuels such as petroleum, coal, and natural gas.
- The two most common types of biofuels in use today are ethanol and biodiesel, both of which represent the first generation of biofuel technology.
- HVO (Hydrotreated Vegetable Oil):
- Paraffinic bio-based liquid fuel originating from many kinds of vegetable oils, such as rapeseed, sunflower, soybean, and palm oil, as well as animal fats. It can be used in conventional diesel engines, pure or blended with fossil diesel (petrodiesel).
- Carbon Dioxide (CO2):
- Primary greenhouse gas emitted through human activities. Carbon dioxide enters the atmosphere through burning fossil fuels (coal, natural gas, and oil), solid waste, trees and other biological materials, and also as a result of certain chemical reactions (e.g., manufacture of cement). Carbon dioxide is removed from the atmosphere (or “sequestered”) when it is absorbed by plants as part of the biological carbon cycle.
- Decarbonization:
- Reduction of carbon dioxide emissions through the use of low carbon power sources, achieving a lower output of greenhouse gasses into the atmosphere.
- HVDC Light:
- HVDC Light is the successful and environmentally-friendly way to design a power transmission system for a submarine cable, an underground cable, using over head lines or as a back-to-back transmission. HVDC Light is HVDC technology based on voltage source converters (VSCs).
- HVDC Light is designed to transmit power underground and underwater, also over long distances. It offers numerous environmental benefits, including “invisible” power lines, neutral electromagnetic fields, oil-free cables and compact converter stations.
- As its name implies, HVDC Light is a dc transmission technology. However, it is different from the classic HVDC technology used in a large number of transmission schemes. Classic HVDC technology is mostly used for large point-to-point transmissions, often over vast distances across land or under water. It requires fast communications channels between the two stations, and there must be large rotating units – generators or synchronous condensers – present in the AC networks at both ends of the transmission. HVDC Light consists of only two elements: a converter station and a pair of ground cables. The converters are voltage source converters, VSC’s. The output from the VSC’s is determined by the control system, which does not require any communications links between the different converter stations. Also, they don’t need to rely on the AC network’s ability to keep the voltage and frequency stable. These feature make it possible to connect the converters to the points bests suited for the AC system as a whole.
- HVDC (High-Voltage Direct Current):
- Key enabler for a carbon-neutral energy system. It is highly efficient for transmitting large amounts of electricity over long distances, integration of renewables and interconnecting grids, opening up for new sustainable transmission solutions.
- HVDC Links:
- The first successful HVDC experimental long distance line (37 miles) was made at Munich, Germany in 1882 by Oskar Von Miller and fellow engineers.
- HVDC allows power transmission between AC transmission systems that are not synchronized. Since the power flow through an HVDC link can be controlled independently of the phase angle between source and load, it can stabilize a network against disturbances due to rapid changes in power.
- An HVDC line has considerably lower losses compared to HVAC over longer distances.
- Neu Connect (the first power interconnection between Great Britain and Germany): https://neuconnect-interconnector.com +
- The NeuConnect Interconnector will create the first direct power link between Germany and Great Britain, connecting two of Europe’s largest energy markets for the first time. Around 720km of land and subsea cables will form an ‘invisible highway’ allowing up to 1.4GW of electricity to move in either direction, enough to power up to 1.5 million homes over the life of the project.
- The Tyrrhenian Link: https://www.terna.it/en/projects/public-engagement/Tyrrhenian-link +
- Connecting Sicily with Sardinia and the Italian peninsula via a double underwater cable: a new electricity corridor at the centre of the Mediterranean; the Tyrrhenian Link. At 950 kilometres long and with a capacity of 1000 MW, this is an infrastructure initiative of international significance, another step towards a more sustainable energy future. The link will improve electricity exchange capacity, facilitate the development of renewable energy sources, and the reliability of the grid.
- The overall project involves two sections: EAST from Sicily to Campania and WEST from Sicily to Sardinia.
- The East section is 480 kilometres long and connects the Fiumetorto landing point, in the municipality of Termini Imerese in Sicily, with the landing point in Torre Tuscia Magazzeno, near Battipaglia in Campania.
- The WEST section is approximately 470 kilometres long and connects the Fiumetorto landing point to the one in Terra Mala, in Sardinia.

- The Eastern Green Link 2 (EGL2): https://www.ssen-transmission.co.uk/projects/project-map/eastern-green-link-2/ + The Eastern Green Link 2 project is a proposal to install a sub-sea high-voltage direct current (HVDC) cable from Sandford Bay, at Peterhead, to Drax in England. There is currently a large amount of forecasted generation that will require connection to the electricity network in the coming years and as such we are proposing several upgrades to the transmission network across the north of Scotland to facilitate this. The Eastern HVDC Link will play a key role in helping achieve our Net-Zero targets.
- The EuroAsia Interconnector: https://euroasia-interconnector.com/ + EuroAsia Interconnector Limited is the official EU project developer of the 2,000MW electricity interconnector between Israel, Cyprus, Greece and Europe. The EuroAsia Interconnector is a leading European Project of Common Interest (PCI) labelled as an EU “electricity highway” connecting the national electricity grids of Israel, Cyprus and Greece through a 1,208 km subsea HVDC cable.
- The EuroAsia Interconnector comprises the electricity interconnection between the grids of Israel, Cyprus, Greece through a subsea DC cable and with HVDC onshore converter stations at each connection point, with a total capacity of 2000MW. The project is an energy highway bridging Asia and Europe, with a total length of 1,208 km. It creates a reliable alternative route for the transfer of electric energy to and from Europe.
- AC (Alternating Current) & DC (Direct Current) & UC (Universal Current):
- Direct current (DC) is an electric current that is uni-directional, so the flow of charge is always in the same direction. As opposed to alternating current, the direction and amperage of direct currents do not change. It is used in many household electronics and in all devices that use batteries.
- Direct current has many uses, from the charging of batteries to large power supplies for electronic systems, motors, and more. Very large quantities of electrical energy provided via direct-current are used in smelting of aluminum and other electrochemical processes.
- in contrast to AC power, DC power is entirely made up of active power, meaning that there are almost no losses due to the capacitance of wires when DC power travels long distances. In fact, high voltage AC transmission systems have losses of 7% to 15% with aboveground transmission.
- Alternating Current is used in homes as Direct current can not be easily stepped up or stepped down with the help of transformers whereas alternating current can easily be converted from low voltage to high voltage or vice-versa with the help of transformers.
- “UC” is used for “Universal Current”, that translates to “either DC or AC”. So a 24 V UC input can accept either 24 V AC or 24 V DC.
- 4 Types of Network Cabling:
- Coaxial Cable:
- Coaxial cables have a single copper conductor at the center, while a plastic layer provides insulation between the center conductor and braided metal shield. The metal shield blocks outside interference from fluorescent lights, motors, and other computers.
- Fiber Optic Cable:
- Fiber optic cables possess a center glass core surrounded by multiple layers of protective materials. They avoid electrical obstruction by transmitting light instead of electronic signals, making them perfect for environments with large amounts of electrical interference. Fiber optic cables have become the standard for connecting networks across buildings because of their resistance to moisture and lighting.
- Shielded Twisted Pair (STP) Cable:
- Often referred to colloquially as simply ethernet cables, STP cables employ a special type of copper telephone wiring used for business installations. An external shield functioning as a ground is added to the standard twisted pair of telephone wires.
- Unshielded Twisted Pair (UTP) Cable:
- Unshielded twisted pair (UTP) cables are broadly used in the telecommunications and computer industries as ethernet cables and telephone wires. In a UTP cable, conductors forming a single circuit are twisted around one another to cancel out electromagnetic interference (EMI) from external sources.
- Coaxial Cable:
- FTTx:
- Fiber to the Home (FTTH), Fiber to the Building (FTTB), Fiber to the Premises (FTTP) and Fiber to the Curb (FTTC), termed as FTTx are various technology and deployment options developed to enable reach of fiber as close to the user location as possible to provide high speed data and voice services.
- Fiber to the home (FTTH) is the delivery of a communications signal over optical fiber from the operator’s switching equipment all the way to a home or business, thereby replacing existing copper infrastructure such as telephone wires and coaxial cable.
- FTTP and FTTH are two different abbreviations for the same thing. FTTP stands for ‘fibre to the premises’ and FTTH stands for ‘fibre to the home’. … Unlike FTTC, FTTP broadband is delivered via fibre-optic cables not only as far as the cabinet, but across the entire span to your home or business.
- Fiber-optic cables are less susceptible to glitches than traditional copper wires and can withstand the shock and vibration from inclement weather. FTTH is considered “future proof” and offers the flexibility to deliver additional services in the years to come.
- Key Differences Between Copper Cable and Fiber Optics:
- Data transmission speed of a fiber cable is comparatively more than that of copper cable. Copper cables are nearly 31% slower in data transmission than fiber cable.
- A copper cable transmits the data through it in the form of electrical pulse i.e., due to the movement of electrons. As against in a fiber optics, the data transmission is the result of movement of photons thus it transmits in the form of light pulses.
- The bandwidth provided by a copper cable is less than that of the fiber optics. Thus, a copper cabling meets the industry standards and provides a performance of up to 10 Gbps. However, a fiber optics due to its large bandwidth possess better performance of up to 60 Tbps and above.
- The energy consumed by a copper cable during its operation is somewhat greater than 10W but on the other side, fiber optics consumes less energy i.e., around 2W per user.
- The lifespan of a copper wire is approximately 5 years as it gets easily affected by temperature variations and other environmental factors. However, fiber optics possess a lifespan of 30 to 50 years.
- As fiber optics are difficult to be tapped as compared to copper cables thus proves advantageous from the security point of view. Due to this reason fiber optics are widely used for data transmission at present time.
- A fiber optics allows transmission of data at a much faster rate as compared to copper cable.
- The installation and maintenance cost of a fiber cable is more than copper cable.
- HVAC-R (Heating, Ventilation, and Air Conditioning – Refrigeration):
- Heating, ventilation, and air conditioning is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality.
- HVACR involves maintaining, repairing and installing heating, ventilation, air conditioning, and refrigeration systems.
