Safety is crucial for Ventolines. This concerns not only safe working during the construction of a wind farm or other renewable energy project but also guaranteeing safety once the project is operational.

This requires extra attention for a large and complex nearshore wind farm like Windpark Fryslân and conducting safety inspections entails thorough planning and the use of specialized equipment.

As part of the safety plan for Windpark Fryslân, Ventolines regularly conducts vessel inspections, focusing on aspects such as health, safety, and environment, cleanliness, certifications, familiarity with procedures and limitations, crew, local conditions, and more.

On March 4, 2024, such a vessel inspection took place during the mobilization of the Seazip 7. The following day, the annual underwater inspection of the foundations of the wind turbines of Windpark Fryslân began.

The scope of the underwater inspection includes various components, such as inspecting the Siemens Gamesa wind turbines using an ROV (Remotely Operated Vehicle) around the piles, cables, and other structures. This involves examining visual damage, wear and tear, marine growth, bottom erosion around the foundations, and the condition of inter-array cables. Additionally, steel thickness measurements are taken at several locations.

These activities are carried out using a vessel from Seazip, with the Tiger ROV underwater robot from Bluestream being deployed for inspections, managed by Deutsche Windtechnik (DWT).

Bluestream has an extensive fleet of more than 20 underwater robots of various sizes to meet the increasing demand for advanced underwater interventions.

Furthermore, the pipes through which the electrical cables run from the substation to the IJsselmeer are also inspected, focusing on damage and other visual abnormalities.
