Null Island is a fictional island at 0⁰ N, 0⁰ E. It is of utility to map databases and computer software. There was a buoy called Soul Buoy at it, but this market concerns a reclaimed land structure or fixed platform of another kind that does not move with the waves, anything merely moored by cables, no matter how tense, will not qualify. A platform consisting of steel beams or the like would though, just as an example, would.
