European governments have recently announced a significant expansion of offshore wind park projects. However, building massive wind farms many miles out to sea contains still a lot of challenges. One key element – sometimes neglected – is cabling. Cable layout at sea, very often with difficult weather conditions, is demanding. Submarine cable repair accounts for over 70% of all insurance claims on installed wind parks though the cable costs when developing a new wind farm make only 7 to 10% of the whole development investment. This clearly shows the need for improvements in this area.
