PROBLEM TO BE SOLVED: To provide a ship bottom shape capable of reducing frictional resistance of a barge type platform for a work barge.SOLUTION: Notch-state recess parts 6, 7 which allow equipment of a push boat for navigation, are provided on a stern part of a work barge, and tunnels 8, 9 penetrating from front parts of the recess parts to a stem FE of the work barge, are disposed on left and right sides respectively in the barge type platform. Plural air bubble promotion materials 11 for generating and making air bubbles stay and generating an air layer between water and ship bottom materials 5a, 5b, 5c are connected toward a width direction of the barge type platform on a flat ship bottom material AE of the barge type platform, and the air bubble promotion materials are projected downward from the ship bottom material over whole width of the ship bottom material. Therefore, when the barge type platform is navigated, by actions of the plural air bubble promotion materials, the air layer is created between the water and the ship bottom materials, so that friction of the ship bottom materials becomes smaller thereby frictional resistance of the barge type platform becomes smaller.SELECTED DRAWING: Figure 6

    【課題】作業船の台船の摩擦抵抗を低減可能な船底形状を提供する。【解決手段】作業台船の船尾部に運航用の押船を装備可能ならしめる切り欠き状の凹部6、7を設け、該凹部の前部から上記台船の船首材FEまで貫通するトンネル8、9が左右両舷に設けられた上記台船において、上記台船の平坦な船底材AEに、気泡を発生させ滞留させて水と上記船底材5a、5b、5c間に空気層を創る為の複数の気泡促進材11を上記台船の幅方向に向けて接続させ、且つ船底材の全幅に亘り、上記船底材より下方に突出させて設けられた台船を特徴としている。それにより、上記台船が運航されるとき複数の気泡促進材の作用により水と上記船底材との間に空気層が出来て上記船底材の摩擦が小さくなって上記台船の摩擦抵抗が減少される。【選択図】図6
