Invention relates to the shipbuilding and ship-repair. Additional pontoon of the floating dock is connected with the main pontoon of the floating dock for increase of its stockpile deck and contains the compartments of buoyancy formed by boards, longitudinal and transverse partitions inclined from the bottom toward the deck of pontoon, which are filled with material with weight of less than one unit. Pontoon has one-piece and air-tight upper deck covering with longitudinal and cross beams. The compartments of buoyancy are fastened to this covering from below and form separate compartments distributed between them, closed from above by deck covering and opened in the lower part for free water inflow into these compartments. Technical result:improvement of operating conditions and servicing the pontoon with simultaneous elimination of overgrowth by algae of its ground parts.
