Renewable Energy Welding & Coating Inspection
Third-party welding and protective coating inspection for wind energy, offshore wind, hydropower and fabricated renewable-energy projects.
Renewable-energy projects depend on large fabricated structures, welded components and protective coating systems produced across complex international supply chains.
Dilenza provides qualified welding and coating inspectors for renewable-energy projects at manufacturers, fabrication yards, construction sites and other project locations worldwide.
Inspector profiles are selected according to the asset, materials, welding processes or coating system, applicable standards, fabrication environment, location and required duration.
Inspection for Renewable Energy Projects
Renewable-energy projects create different inspection requirements according to the technology, structure and operating environment.
A wind tower manufacturer may require welding inspection throughout fabrication. An offshore wind foundation may require both structural welding inspection and intensive corrosion-protection inspection. A hydropower project may involve fabricated steel, piping, pressure-containing components and coated equipment.
Dilenza structures the inspection requirement around the actual project.
