A floating structure (1) for transporting and installing a floating tension leg platform (TLP) (2) having a plurality of legs (3) radiating from a central point (4) is provided. The floating structure comprises: controllable ballast tanks (6, 6 ') for changing the buoyancy of the floating structure; and engagement means (9) engaged with the legs (3) of the TLP and maintaining the legs (3) at the desired draft during transportation and installation. The floating structure comprises a plurality of floating structure portions intended to be positioned horizontally near each leg of the TLP and provided with engagement means (9), in such a way as to engage mating engagement means provided on the legs of the TLP, such that in an operational position of the floating structure in which the floating structure portions are positioned horizontally alongside the legs of the TLP, the engagement means (9) engage mating engagement means provided on the legs of the TLP. The engagement means can be loaded on the mating engagement means with a downward force opposite the upward buoyancy of the TLP, and the engagement means are further arranged such that the engagement means can be engaged with the mating engagement means in the above-mentioned manner even when the legs of the TLP are at least partially located at a height above the sea level.

    提供了运输和安装浮式张力腿平台TLP(2)的浮式结构(1),TLP(2)具有从中心点(4)辐射的多个腿(3)。浮式结构包括:可控压载舱(6、6’),改变浮式结构的浮力;及接合装置(9),与TLP的腿(3)接合并在运输和安装期间将腿(3)保持在所需吃水深度。浮式结构包括多个浮式结构部,旨在水平定位在TLP的每个腿附近且设置有接合装置(9),以如下方式与设置在TLP的腿上的配对接合装置接合,使得在浮式结构部水平地定位为与TLP的腿并排的浮式结构的操作位置中,接合装置能以与TLP的向上浮力相反的向下力对配对接合装置加载,且接合装置还布置为,即使当TLP的腿至少部分地位于海平面以上的高度时,接合装置也能够以上述方式与配对接合装置接合。
