Robin Rigg Wind Farm
Robin Rigg site personnel identified a hydraulic oil spillage on several levels of a wind turbine platform which posed a potential contamination risk to the coastal waters off Cumbria. After an initial survey by Adler and Allan it became clear that the oil had made its way down cables and the mastic sealer had degraded, allowing oil to migrate to the lower platforms of the turbine.
Following the survey, Adler and Allan was tasked with cleaning-up the hydraulic oil spillage on the platform. Containment products had been put in place but something less obtrusive and longer-lasting was required to prevent future spills. The scope of works included cleaning the oil spillage from all ducting, walkways, cables and platform areas. As the cables were live, a zip-up scaffold and SSOW was used before works could commence. Some oil had made it onto the lower deck, so grates required lifting to prevent it reaching the floor underneath. Personnel used large sprayers with cleaning fluid degreaser, rags, hydrophobic spill sheets and deck scrubbers to complete the clean-up. Power washers could not be used as this would have caused contamination to enter the sea. Once cleaned, the exposed cables required sealing. All oil absorbent materials, rags and contaminated waste were safely returned to shore for compliant disposal by Adler and Allan.
Adler and Allan safely and quickly contained the spill over a two day period, preventing pollution of the surrounding area.
