    • A construction method for fixing a foundation of a waterborne structure including an offshore platform to a seabed (2) is described. The foundation includes at least one hollow column (108) which incorporates a pile cap (43) at its bottom. In the method, piles (49) are driven into the seabed (2) to a design depth, and the hollow column (108) is then lowered to the seabed (2) so as to surround the pile group and be supported thereby. Concrete is cast into the bottom of the hollow column (108), wherein reinforcement steel bar (45) has been pre-installed to translate the conventional mass concrete plug into a reinforced concrete small pile cap (43) adapted to support the hollow column (108) thereon during construction. The hollow column (108) is de-watered, excessive pile length is cut, and pile cap reinforcement (47) is fixed followed by concrete casting of the pile cap (44). A platform deck is then installed and constructed on top of the now-fixed hollow column (108).
    • 描述了一种用于将包括海上平台的水上结构的地基固定到海床(2)的施工方法。 该基础包括至少一个在其底部结合有桩帽(43)的空心柱(108)。 在该方法中,桩(49)被驱入海床(2)至设计深度,然后空心柱(108)下降至海床(2)以围绕桩群并由此被支撑。 混凝土被浇注到空心柱(108)的底部,其中已经预先安装了加强钢筋(45)以将传统的大体积混凝土桩平移到适于支撑中空柱的钢筋混凝土小桩帽(43) 108)在施工期间。 将空心柱(108)脱水,切割过长的桩的长度,并固定桩帽加强件(47),然后浇注桩帽(44)的混凝土。 然后在现在固定的中空柱(108)的顶部安装并构建平台甲板。

    • Provided is a method of installing and constructing a hollow cylindrical pier for fixing an offshore platform structure to the bed, wherein a steel cylinder (101) with an inner diameter slightly greater than the hollow cylindrical pier is driven into the bed (2) until at least the bearing stratum is reached to ensure fixing, and part of the steel cylinder (101) is exposed above the water surface (1); draining ponding inside the steel cylinder (101), and excavating bed sediment inside the steel cylinder (101); cutting off the steel cylinder (101); hoisting a first hollow cylindrical pier section (1A) with a sealed bottom end vertically downwards from the water surface (1) towards the steel cylinder (101), pre-tensioning an overlapping hollow cylindrical pier section on the hollow cylindrical pier section via a shear key structure and then fixedly connecting same with the previous hollow cylindrical pier section, and hoisting same in turn such that after the sealed bottom end of the first hollow cylindrical pier section (1A) reaches near the bottom end of steel cylinder (101), at least part of the lastly hoisted overlapping hollow cylindrical pier section is exposed above the water surface (1); and pouring concrete (107) into a gap between the steel cylinder (101) and the hollow cylindrical piers. Further provided are a method of installing and constructing an offshore platform structure and a hollow cylindrical pier for fixing to the bed and an offshore platform structure.
