This platform looks like a landing-pontoon. Also it can be, that it was former a boot (lighter). It is old and corroded, but we don´t know from what time it is. It is the landing pontoon which used from 1949 to 1953, or is it used for the oil drillings in 1958, or was it needed for the nuclear test "Kraton 2" in the year 1978?
