A floating platform for use in a body of water comprises an uppermost buoyant and ballastable hull partially submerged in the water without contacting the floor of the body of water and usually without being moored to the floor of the body of water. The bottom of the uppermost hull is attached to the top of a lower buoyant and ballastable hull after the lower hull has been completely submerged in the water and anchored to the floor of the body of water with flexible moorings.
