Cable giant to cooperate with Infratek

- Infratek has solid specialist expertise in high-voltage cable work. That Prysmian, one of the world's largest cable manufacturers, has chosen to collaborate with Infratek's project department, helps to emphasize our expertise and experience, says Infratek Lars Bangen, CEO of Infratek.

To ensure a safer power supply in and around the capital, Statnett upgrades the grid between Smestad and Sogn in Oslo. On behalf of Prysmian Netherlands B.V will Infratek carry 24 cable drums of 45 tonnes to location, install 25 kilometers of cable in the tunnel from Smestad to Sogn, perform detailed projects and design steel structures for the cables as well as perform all cable extensions and terminations. Infratek is responsible for all coordination in the areas.

At Sogn Substation, Infratek will also install cable through a 40 meter long vertical shaft. The design and installation of tunnel lighting is also part of the contract.

Cable work in the tunnel will start January 2020.

The cable enthusiast

Kristian Dahl (32) is one of Infratek newest project managers, and his speciality is cables. He has just completed one of his first projects and his biggest by far: relaying the cable in one of Oslo’s main electrical arteries – a cable of huge social importance at the site of the new Økern Portal.

Økern is an area of Oslo that is developing rapidly. On its completion in 2020, the gigantic commercial complex Økern Portal is sure to become a central feature of this section of the city. However, Økern is also a centre for infrastructure under the ground.

- A cable connection on the site, critical to the smooth functioning of the local community, was identified during the project design phase of the Økern Portal commission. Relaying the 300 kV cable had to be completed rapidly to prevent delaying the other parts of the construction process. Infratek delivered the best solution proposal, with the fastest delivery,” relates Kristian Dahl.

The cable is owned and operated by Hafslund Nett, although Statnett holds overarching responsibility.

From subsea cables in the UK to underground cables at Infratek

Having completed his degree in marine technology and cybernetics at the Norwegian University of Science and Technology (NTNU), working with cables was not the most self-evident career choice for Kristian. However, when he landed a job in the UK working with offshore projects and offshore cables, his interest in the area was awakened.

- Before joining Infratek, I worked for DeepOcean where I was involved in major subsea cable projects and wind farms. For example, I worked on a major initiative designed to link the whole of Europe together in a giant electrical grid using subsea cables. One of the places I worked in here was the department tasked with tendering for subsea cable projects, and this was where I began to develop an interest in cables, explains Kristian.

Field engineer, engineering manager, project engineer. Kristian held a variety of positions with plenty of responsibility.

After a few years in the UK, however, he was ready to return home to Norway.

- When the Infratek job opened up, it was a great opportunity and a challenge. I’ve made great strides as a project manager since I joined Infratek, especially with regard to land cable commissions. My work involves a much higher level of cable technology skills than previously, and it’s been a steep learning curve. I was given plenty of responsibility as soon as I started at Infratek, says Kristian.

Collaboration with the world's largest cable manufacturer

Infratek won the Økern project in May. The project was a dream come true for a cable enthusiast, with regard to both project partners and unique cable solutions.

- This project took the form of a working relationship with the Dutch branch of the Italian company Prysmian, one of the biggest cable manufacturers in the world. Infratek was the general contractor, with Prysmian participating as a subcontractor. It’s fascinating to work with the best in the business, adds Kristian.

As early as a month after winning the Økern project, work was already under way to test cables at a facility in the Netherlands.

- A heavy-duty test set-up was established in the Netherlands to confirm that jointing from copper to aluminium worked well, and that there were no problems with jointing cables from two different manufacturers.

- Because the cable we were to lay is so important to the power grid in Oslo, the disconnect window was extremely tight. This meant that the relaying work – involving cutting, relaying along a new line, and jointing the cables – had to be done quickly, and we were operating to tight deadlines. The tests and preliminary work we completed in the Netherlands proved crucial to successful execution,” emphasises Kristian.

The new cable is one of the largest (by cross-section) ever laid in Norway: 3,000 mm2 aluminium with a voltage of 420 kilovolts. The cable was brought online on 19 October.

- The connection process ran smoothly – everything worked the way we wanted. It was an exciting project where we learned a lot and had the chance to work with great people who had all kinds of knowledge to share. Great teamwork every step of the way, says Kristian.

The new cable line at Økern is now completed; it is 250 metres long, with 36 metres running alongside the pedestrian/cycle path on Lørenveien, 140 metres under Dag Hammarskjølds vei, and the remaining 74 metres routed through a green area.

The project manager can now look forward to taking on a variety of new projects.

- We’ve just completed the Økern project, and I’m currently involved in several tender processes. We’re also working on a temperature measurement commission for Hafslund before starting work on a number of other projects. There’s plenty to keep us busy, which is just the way I like it, he concludes.

Customer:
Hafslund Produksjon AS
Place:
Vamma, near Glomma in the Municipality of Skiptvet, Østfold
Work done:
Cooling and emptying the facility

Vamma 12 is the name of the new hydropower plant in Glomma, with an absorption capacity of 500 cubic metres of water per second. Infratek is responsible for cooling and emptying the facility.

In 2015, Hafslund decided to upgrade and expand Vamma hydropower plant in Glomma Production in Vamma currently amounts to 1,350 GWh per year, corresponding to fully 14 per cent of Oslo’s power consumption. The new unit will generate more than 1,000 GWh per year – 230 GWh of which will be completely new power, with the remainder replacing production from the old units. Vamma 12 delivers greater absorption capacity combined with improved efficiency; it also makes the power plant less vulnerable to outages and loss of production.

Infratek is tasked with installing around 900 metres of pipework in dimensions of 50 to 500 mm, with the associated bends and flanges. The system also features 23 shut-off valves and non-return valves. Moreover, Infratek is to deliver seven pumps in sizes from 2.4 to 170 kW, as well as two cooling water filters with automatic valves.

“Infratek is responsible for the cooling system for the entire facility and for the emptying system. Water cooling in such a huge hydropower plant requires all kinds of equipment, including storage and oil pressure units. Our job is to set up water intakes and to filter the water that flows in at various cooling points in the unit. The pumps we are to deliver will be used to empty drain water and cooling water from the basin,” explains Pål Hystad, fitter and team leader at Infratek.

alt

“It’s is a heavyweight power plant that’s being built and expanded here. Vamma 12 features a head of 28.5 metres, and the absorption capacity of 500 cubic metres per second is simply enormous. By way of comparison, a standard household uses around 150–200 cubic metres of water per year,” he adds.

Welding work

Infratek employee Emil Glommen Engebretsen is busy joining and welding 6-metre-long sections of acid-resistant pipes that stretch up towards the top of the tall installation.

alt

“The welding technique is called TIG (Tungsten Inert Gas), which means that the pool crater and the electrode are protected by a gas flowing from the welding gun. The protective gas makes it possible to weld in an oxygen-free environment, preventing damage to the weld. The pipes that are being welded together are also filled with back gas – the acid-resistant pipes, that is,” says Glommen Engebretsen.

Installation of the pumps and emptying equipment is set to commence in winter, when the facility has begun to take shape and the various compartments have been poured and built.

Completion in 2019

Infratek has been working on the Vamma project since January 2017, and the project is scheduled to continue until autumn 2018, with follow-up running until May 2019.

“With the work we’re doing on this plant, we’ve had to be involved from the very start because we’re embedding all the pipes in concrete. It’s exciting to have Infratek involved in such a large construction project, where Vamma is cementing its position as the biggest hydropower plant in Norway,” concludes Pål Hystad.

The Vamma 12 project is scheduled for completion in spring 2019.
