Balance of Plant (BoP) inspections
Managing the safety, risks and maintenance of wind turbines starts with the condition of the structure below water and at sea level. Balance of Plant inspections focus on the structural condition of critical components such as the transition piece, foundation and secondary steel structures in the splash zone. In these areas, cyclic loading, corrosion and impact have a direct effect on fatigue, connections and safe access.
By carrying out targeted inspections for corrosion, cracking, bolted connections and coating condition, a realistic and technically substantiated picture of the asset’s condition is created. This enables BoP inspections to support asset owners and operators in managing risks and substantiating maintenance, availability and the service life of wind turbines.
Certainty and control for wind turbines
Control Union combines several certified inspection disciplines within a single BoP campaign, including visual inspections and condition assessments, NDT and wall thickness measurements, bolt and flange inspections, and certified coating inspections.
Inspections are carried out using rope access, drones and remote monitoring, tailored to the location and risk profile. This integrated approach reduces mobilisation efforts and provides a complete and consistent overview of the asset’s condition through a single inspection partner.
Structural condition of BoP components
Inspections of the transition piece, foundation and secondary steel provide insight into loading, damage and integrity under offshore conditions.
Focused on critical areas of the turbine
Inspections focus on transition pieces, foundations and boat landings, where wave loading and corrosion are at their highest and damage occurs most quickly.
Focus on demonstrable damage patterns
Each inspection targets visible and measurable damage such as corrosion, cracking, loosened bolted connections and impact damage caused by vessels.
Scope tailored to the wind farm
The inspection scope is defined based on the specific wind farm, the structures present and the risk profile, ensuring that only relevant components are inspected and that results can be applied directly.
Structure and access in a single inspection
Structural components such as the transition piece and secondary steel are inspected together with access systems such as ladders and platforms, reducing the number of mobilisations required and creating a complete overview.
Applicable within the wind farm
BoP inspections are carried out on turbine-related structures within the wind farm and, where applicable, on offshore substations with comparable structures and loading conditions.
