According to satellite imagery made available by Planet, Project 02690 class floating crane SPK-54150 – based at Sevastopol for the Russian Black Sea Fleet – has returned to Snake Island on, or before, 15 May 2022.
The whereabouts of SPK-54150 between today and when it departed the area on 12 May 2022 is unknown, but imagery from Sentinel dated 14 May 2022 shows it returning to the island.
Located at 45.224993 30.744780, the shape, colour and size of the floating crane can be clearly seen. The wake behind also shows the very slow speed it is travelling at – the class averages a speed of 6 knots generally.
Collected at 0857z, the floating crane is approximately 42 kilometres away from Snake Island – or 23 nautical miles.
Based on the average speed of 6 knots, it is actually more likely that SPK-54150 arrived around 1230z on the 14th. Obviously, this if it went direct from the spot located. Imagery is not available of Snake Island on 14 May 2022 later than this as far as I’m aware.
The resolution of the imagery available to me doesn’t show whether the floating crane has any cargo. No doubt further high resolution imagery will appear soon.
