In a windmill, there are parts that rotate. These parts (including various bearings, gearbox, generator) are often lubricated with grease, oil or a lubricant to prevent damage from friction. If the performance of the lubricant deteriorates, damage can occur. By assessing the consistency of the lubricant at regular intervals against original specifications, we can also indicate whether the lubricant should (or should not) be replaced to prevent damage to parts. If damage has already occurred, we can analyze it and detect it as metal particles in the lubricant. By taking action, you can then prevent further damage.
A wind turbine upright is basically “a kind of enclosed pipe” that is not accessed by workers on a daily basis. Air quality problems, for example microbiological (fungi), can occur in this tube under certain conditions. To determine whether air quality is in order, we can use air samples and swipes to conduct an occupational hygiene survey. After analysis in our laboratory, the values can be compared with the prevailing limit values and it can be indicated whether the employee can safely enter the room and under what conditions they can work there.
When there has been a fire in a windmill, we can also conduct an occupational hygiene investigation perform. After a fire, you then want to know what hazardous substances were created during the fire?, to what extent they can still be found in the atmosphere inside the windmill? and to what extent they have been deposited on the walls. Here we generally look at Polycyclic aromatics, monocyclic aromatics, volatile hydrocarbons, total oil, aldehydes, anions, heavy metals (Chromium-6), polychlorinated biphenyls (PCB – 7 Congeners) and we perform an element scan with the ICP (Induced Coupled Plasma). Again, we compare the values found with the limit value and can indicate whether and under what conditions work can be done.
