Reminds me of the huge Titan, known by nickname Herman the German (US Navy YD-171), a large floating crane used at Long Beach Naval Shipyard. After the yard was closed it was sold to Panama Canal authority. PS – originally it was a WW2 war prize taken from Germany by USA. PS2 – this new harbor crane is amazing!
