On 24th of May 2009 we tested the couter ballast system installed at the platform at the Kreidesee in Hemmoor in a safety drill.
Elisabeth Kristoffersen is diving down to a depth of 40m attached to the main line by a lanyard on her wrist. Upon arrival at the bottom plate she pulls so the surface crew knows, she is ready.
Then, the break is released so the counter ballast sets in and two men pull the rope up in addition. The pulling style is from the Skandalopetra diving.
It takes 41 seconds for Elisabeth to dive dow and only 34 seconds for her retrieval, including 5-6 seconds to release the weights.
