Det Norske Veritas, ECN, WMC, BREM, VanderHoekPhotonics, Deltares and other partners have launched a joint industry project called "Cable Lifetime Monitoring" to reduce the fault level
of cables in offshore wind farms.
Cable lifetime monitoring project launched to reduce offshore wind farm failures
Offshore power cable failures are often the main risk
affecting the development and operation of offshore wind farms.
Deltares explained that nearly 80% of insurance claims in the offshore wind industry are related to
cable failures.
"The aim of this study is to reduce power cable failures
in offshore wind farms.
One idea to be developed in this project is to continuously monitor the integrity
of power cables throughout their entire life cycle through advanced fiber optic sensors.
Deltares maritime expert Jan-Joost Schouten said
.
"Continuous monitoring of the health of the cables enables possible faults
to be detected at an early stage.
By preventing a large number of cable failures caused by damage during manufacturing, installation and operation, we believe our research will be able to significantly reduce the levelized cost of electricity (LCoE)
for offshore wind.
" Schouten added
.
Although power cables typically account for only 5-10% of the total investment costs of offshore wind farms, they have so far been responsible for most of the unavailability of wind farms and the cost of claims for
millions of euros per year.
Due to weather conditions or limited availability of equipment and vessels, cable repairs can often take weeks or even months
.
This can seriously hurt revenue and also reduce the technical life of
offshore wind farms.
An early analysis conducted by Det Norske Veritas has shown that cable failures are partly attributable to manufacturing, design and installation errors
.
In addition, morphological dynamic processes such as sand waves are known to expose submarine cables, which significantly increases the risk of
third-party damage.
The project will run from mid-2018 to mid-2020
.
The project's partners hope to reduce the levelized electricity costs, insurance costs and CO2 emissions
in the offshore industry by improving the reliability of offshore wind.
