Conventionally, the offshore structure of this scale was transported to the site with the upper body placed on a purge, and the upper body was loaded with a crane of a crane ship onto the support legs that had been installed in advance on the square bottom, and both were mounted. A fixed covering is constructed. However,
> In the case of tFiJ Nibran 1~ or offshore structures for oil drilling, cutting the upper body and fQffj are very difficult, so build it as one piece and use a marine crane to attach it to the support legs. However, depending on the capacity of the offshore crane, the upper body is constructed by dividing it into multiple relatively small blocks (modules), and these are sequentially placed on the support legs starting from the lower layer. After that, we are making connections such as piping and wiring between each block.
C1 Ki Z! There was a lot of loading work at sea under harsh conditions and connection work after the 18th war, which was inefficient.
There is a problem that jvJ is long and costs increase.

According to the present invention, a marine structure can be easily built horizontally, and there is no need to mount the upper body on support legs using the conventional method. Therefore, even for large offshore structures, regardless of the capacity of the offshore crane, the upper body can be constructed in one piece in a factory, making it possible to construct the upper body in one piece. It is possible to obtain a new structure and shorten the period of construction of the upper body. J, T, Sea 1 - There is no need to install the upper body on a crane, and connection work such as piping and wiring at sea is significantly reduced compared to conventional methods, reducing the time required for on-site work), G 7. It can be shrunk and the construction period can be reduced. Combined with i7 contraction! It is possible to down the sea by 1 stroke. Furthermore, it is not necessary to place the upper main body on a purge and transport it to the site (the upper main body itself floats).Details of this invention will be described below with reference to the drawings I'll give you an explanation.

At the site, adjust the buoyancy of the auxiliary floating body (10).
, the support leg upper part-I part (9) is submerged under the sea surface, and this is the support leg upper part upper part (9) fixed to the upper body (4).
6) Move the auxiliary floating body (10) so that it is dry. So, help? Adjust the 1 horn of 7 bodies (10)
If L, insert the protrusion (5) at the lower end of the upper part (6) of the upper part of the support leg into the lower part of the lower part of the support leg, and weld the upper part (3) of the lower part of the support leg (
6) and the upper part (9) (see Figure 2). By this, the support leg upper part (3) is fixed to the main body (11) and the auxiliary floating body (10) is attached to this part (3).
=j' The state becomes LJ. 4 [Oh, the work to get to this state can be done either on the train that transported the upper body (4) to the site or on any stage Ivi up to that point. Regardless of size, the support leg upper part F part (9) is the same as the upper main body (4).
- Place the top ice (A (4) on the purge (7))
When the upper part of the support leg is connected to the upper part (6) of the support leg, the support leg can be connected to the upper part (6) of the support leg. In addition, the lower part of the support leg (9) may be constructed on site.The support surface F side part (3) does not necessarily have to be divided into two parts, and the upper part of the support leg is crushed into one piece. 3), after constructing the upper body (/l), and placing the upper body (/I) on the purge (7), and after transporting the upper body (4) to the site, It may be fixed to the main body (4). In addition, if the upper body (4) to which the support leg upper part 5), ), or you can take it (=J) by then.
