To provide a barge type platform for a work barge further improving propulsion efficiency while efficiently forming an air layer in between a ceiling surface of a concave water flow groove and water.SOLUTION: A barge type platform for a work barge composed to navigate by installing a push boat at a rear end part of a non-self-navigation type hull not having a propulsion device and operated by power assistance is configured such that: a lower opening concave water flow groove is formed on a ship bottom from the rear end part of the hull to a stem; a front end part of the concave water flow groove is opened above the water line as well as formed in a divergent tapered configuration; right and left end edges are formed from the tapered base part to the rear in a divergent tapered configuration; a bow part position in a ship bottom part of the concave water flow groove rises at a sharp angle; a concave water flow groove ceiling surface in the rear of the risen bow part rises from the bottom part at a sharp angle; an inclined surface totally rising from the bow unit rear end to the rear of the ship bottom part is formed; and at the same time, the ship bottom part inclined surface of the concave water flow groove rising to an end of the concave water flow groove is positioned in water below the water line in navigation.SELECTED DRAWING: Figure 1

    【課題】凹状流水溝の天井面と水との間に空気層を効率的に形成しながらも、推進効率を更に向上させる作業船の台船を提供する。【解決手段】作業船の台船は、推進装置を有しないで他力で運行される非自航型式の船体の後端部に押船を設置して運航するように構成した作業船の台船であって、船体の後端部から船首材まで船底に下方開口凹状流水溝を形成し、凹状流水溝の前端部は喫水線よりも上に開口させると共に前末広がりのテーパー形状に形成し、テーパー基部からは左右端縁を後方まで末広がりのテーパー形状に形成し、凹状流水溝の船底部の船首部位置は急角度で立ち上げ、立ち上げた船首部後方における凹状流水溝天井面は底部より急角度で立ち上げ、船首部後端から船底部後方にかけて全面上昇する傾斜面を形成し、しかも、凹状流水溝終端まで上昇する凹状流水溝の船底部傾斜面は運航時の喫水線よりも下方の水中に位置するように構成してなることとした。【選択図】図1
