  • the piling barge is positioned in the predetermined pile-sinking sea area. Specifically, at first, the piling barge is initially positioned by a windlass vessel, then the supporting legs of the piling barge are sunk through into the seabed ground, therefore achieving positioning of the piling barge and thus providing a foundation for the subsequent pile-turning and pile-sinking operations. 3.

The adjustment of the operating position is achieved, facilitating the piling operation.
  • FIG. 11 is the schematic diagram of position adjustment of the pile frame of the piling device, and in which the position of the pile frame in original state is indicated by solid lines, and the adjusted position of the pile frame in operating state is indicated by broken lines.
  • the luffing angle of the boom 530 i.e., the angle between the boom 530 and the hull 100 may be changed by means of the luffing winch mechanism.
  • the pile frame 510 With the luffing oil cylinder remaining unchanged, the pile frame 510 will be transferred from the state A 0 to a state A 2 , thereby the contacting position between the pile and the seabed ground and also the inclination angle of the pile is changed, meeting requirements for offshore foundation engineering operation.
  • the pile frame 510 may be transferred from the state A 0 to a state A 3 . Accordingly, the contact position between the pile and the seabed ground is changed, while the inclination angle of the pile may also be adjusted, so that the position of the pile frame 510 may be adjusted in a wider range and in more aspects, which provides more conveniences for the position adjustment of the pile. In combination of the above described three aspects, adjustments for the pile frame 510 in all directions may be achieved.
  • the position of the pile frame 510 can be adjusted within a wide range through the turntable 550 , the luffing oil cylinder 540 and the luffing winch mechanism, thus repeatedly positioning for the piling barge is no longer needed. Therefore, the working efficiency of the piling barge is improved.
  • the luffing oil cylinder 540 may be directly hingedly connected with the hull 100 .
  • the lower end of the boom 530 may also be directly hingedly connected to the hull 100 and the luffing winch mechanism is mounted on the hull 100 , which may also change the luffing angle of the boom 530 and thus adjust the position of the pile frame 510 .
