The invention discloses a shipboard supporting structure used for integrally dismounting offshore platform topside module by means of two boat flotage. The shipboard supporting structure comprises a bracing frame, the bracing frame is fixedly connected with a floating barge, the bracing frame is provided with a cantilever which extends outwards, the cantilever is fixedly connected with a sleeve, the interior of the sleeve is provided with a jack, a rigid bearer, a buffer unit and a supporting structure from bottom to top, the supporting structure is provided with a holding bowl matched with a semispherical supporting point, the holding bowl makes spherical surface contact with the semispherical supporting point, and the dynamic friction coefficient of the holding bowl and the semispherical supporting point is smaller than 0.1; a supporting central spindle is arranged under the holding bowl, the supporting central spindle traverses the buffer unit and is fixed on the rigid bearer, the upper part of the supporting central spindle is fixedly connected with a holding bowl supporting structure, the outer contour of the holding bowl supporting structure is cylindrical, a buffer rubber sheet is embedded into the cylindrical outer wall of the holding bowl supporting structure, and the outside surface of the buffer rubber sheet is contacted with the inside surface of the sleeve. The shipboard supporting structure only transmits vertical gravity and basically does not transmit bending moment caused by self-rolling of the boat.
