New DNV GL Guidelines and Practices Ensure Safe Connection of Offshore Wind to the Transmission Grid Using High Voltage DC Technology
New DNV GL Guidelines and Practices Ensure Safe Connection of Offshore Wind to the Transmission Grid Using High Voltage DC Technology

ARNHEM, the Netherlands, Sept. 22, 2014 /PRN=KYODO JBN/ --
- Growing number of offshore wind farms being built farther from shore increase
need for reliable measures for the use of HVDC transmission systems
- DNV GL's new recommended practice on technology qualification of offshore
HVDC technologies provides a means for managing technology risks and
facilitating a faster, more efficient and more reliable deployment of offshore
HVDC transmission
- Joint Industry Project partnered with major industry players including: ABB,
Alstom Grid, DONG Energy, Elia, Europacable, Scottish Power, Statkraft,
Statnett, Statoil, Svenska Kraftnat and Vattenfall.
DNV GL, [http://www.dnvgl.com/energy/] a leading global energy advisory and
testing authority as well as the world's largest resource of independent energy
experts, has together with the Swedish Transmission Research Institute (STRI)
and ten industry players developed a methodology for technology qualification
of offshore High Voltage Direct Current (HVDC) technologies through a joint
industry project.

As offshore wind farms are being built farther from the coast and more offshore
oil and gas installations are powered from shore, there will be an increasing
need for long-distance underwater power transmission in the years to come. Use
of HVDC transmission allows power transmission through cables over longer
distances and higher capacities compared to what is feasible when using AC
transmission, and will hence often be the preferred solution for long-distance
power underwater transmission.
However, to date operational experiences with offshore HVDC transmission
technologies are very limited and there is a lack of relevant standards,
guidelines and recommendations for stakeholders to rely on.
Peter Vaessen, Segment Director Future Transmission Grids at DNV GL comments:
"Implementation of new technology always introduces uncertainties that imply
risk for its developers, manufacturers and end-users. With this technology
qualification, we enable our customers to provide the evidence that the
technology used will function within the specified limits with an acceptable
level of confidence. Customers can ensure that each step is agreed in advance
with the technology provider and the buyer, whilst delivering projects on time."
The immature nature of offshore HVDC technologies causes uncertainties and
increased risk exposure for stakeholders and makes the projects complicated and
costly. As a means to manage the technology risks associated with offshore HVDC
transmission projects, DNV GL and STRI have developed a recommended practice on
technology qualification of offshore HVDC technologies through a joint industry
project with ten industry players. The new recommended practice is based on DNV
GL's methodology for technology qualification, which has been used extensively
for managing technology risks in the oil and gas industry for more than a
decade.
Technology qualification is a method for providing evidence that technical
equipment will function within specified operational limits with an acceptable
level of confidence, both for suppliers and buyers of the relevant equipment.
In order to accurately incorporate feedback from all major stakeholders during
the testing process, this Joint Industry Project partnered with major industry
players including: ABB, Alstom Grid, DONG Energy, Elia, Europacable, Scottish
Power, Statkraft, Statnett, Statoil, Svenska Kraftnat and Vattenfall.
With several distinguishing features, a DNV GL recommended practice is more
than just a guideline. It is the result of a collaborative effort of an
industry-wide consortium. Like all of the 100+ recommended practices DNV GL
manages, the recommended practice on technology qualification of HVDC
technologies will be extensively peer reviewed, professionally formulated and
published, and regularly updated.
