To provide a floating type foundation fabrication method capable of stably and smoothly transferring a heavy semi-submersible type concrete foundation to a trestle.SOLUTION: A fabrication method for a floating type foundation which is a semi-submersible type foundation 70 supporting a tower of an offshore windmill comprises at least: a segment body fabrication process to fabricate a center column foundation 71, a side column foundation 73 and a pontoon 70C as segment bodies on trestles 40 in respective fabrication yards; a segment body transfer process to transfer the trestles 40 with respective segment bodies mounted thereon to a connection yard using multi-axis trolleys; and a connecting process to fabricate the floating type foundation 70 by connecting segment bodies to each other. Each multi-axis trolley is arranged with an axis direction thereof parallel to or normal to at least one of three or four pontoon axial directions. All wheels on one trolley are controlled to be steered in an identical or almost identical direction.SELECTED DRAWING: Figure 2

    【課題】重量のあるコンクリート製のセミサブマージブル型基礎を安定的かつスムーズに台船に搬送できる、浮体式基礎の製作方法を提供する。【解決手段】洋上風車のタワーを支持するセミサブマージブル型基礎70である、浮体式基礎の製作方法であり、少なくとも、センターカラム基礎71とサイドカラム基礎73とポンツーン70Cをそれぞれ分割体としてそれぞれの製作ヤードにおける架台40の上で製作する分割体製作工程、それぞれの分割体を搭載したそれぞれの架台40を多軸台車により接続ヤードに搬送する分割体搬送工程、分割体同士を相互に接続して浮体式基礎70を製作する接続工程を有し、それぞれの多軸台車の車体軸方向を、3方向もしくは4方向のポンツーン軸方向の少なくともいずれか一つの方向に平行もしくは直交するようにして各多軸台車を配設し、全ての車輪を同一方向もしくは略同一方向に制御する。【選択図】図2
