The invention provides a self-installation type offshore platform, and relates to the field of offshore platforms. The self-installation type offshore platform comprises a ship body, a lifting mechanism and at least three pile legs, the at least three pile legs are circumferentially installed on the ship body at intervals, the lifting mechanism is in transmission connection with the pile legs, a winch is further arranged on the ship body, and the winch and the pile legs are arranged in a staggered mode; a connecting anchor point is arranged on each pile leg, an anchor chain is connected between the winch and the connecting anchor point, the pile leg has a rising state and a lowering state, and in the rising state, the connecting anchor point is located at the position close to the ship body; and in the lowering state, a vertical distance is formed between the connecting anchor point and the ship body, and the anchor chain or the rope is inclined to the pile leg and is tensioned between the connecting anchor point and the winch. Effective anti-inclination constraint is formed on the pile legs through the tensioning effect of the anchor chain or the rope, and the pile legs are prevented from shaking relative to the ship body. Compared with the prior art, the operation of specially installing a connecting assembly is omitted, the pile legs can be rapidly and effectively locked through the winch and the anchor chain or the rope, the actual operation difficulty is low, and the locking effect is better.

    本发明提供了一种自安装式海上平台,涉及海上平台领域。自安装式海上平台包括船体、升降机构和至少三个桩腿,至少三个桩腿周向间隔安装在船体上,升降机构与桩腿传动连接,船体上还设有绞车,绞车与桩腿错开布置;桩腿上设有连接锚点,绞车和连接锚点之间连接有锚链,桩腿具有升起状态和下放状态,在升起状态时,连接锚点处于靠近船体的位置;在下放状态时,连接锚点与船体之间形成竖向间距,锚链或绳索倾斜于桩腿拉紧在连接锚点和绞车之间。锚链或绳索的拉紧作用对桩腿形成有效的防倾约束,防止桩腿相对船体晃动,相比于现有技术省去了专门安装连接组件的操作,利用绞车和锚链或绳索即可快速、有效地锁住桩腿,实际操作难度低且锁紧效果更好。
