この発明は海洋構造物の建造方法に関し、ドックの大き
さを超える海洋構造物を効果的に建造する方法を提供し
ようとするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for constructing a marine structure, and an object thereof is to provide a method for effectively constructing a marine structure larger than a dock.
近年海洋構造物が大型化してきており、ＴＬＰ（Ｔｅｎ
ｓｌｏｎ Ｌｅｇ Ｐｌａｔｆｏｒｍ）等では既存のド
ック巾を超える大きさのものを建造する必要が生°じて
いる。In recent years, offshore structures have become larger, and TLP (Ten
In some cases, such as slon leg platforms, there is a need to build something larger than the existing dock width.
従来ドック［１］を超える構造物を建造する場合には、
構造物をドック内に納まる大きさに分割して建造した後
継げるか或いは洋上にパージを浮べてこの上で建造する
等の方法がとられていた。When constructing a structure that exceeds the conventional dock [1],
Methods were used such as dividing the structure into pieces that could fit inside the dock and constructing successors, or floating a purge on the ocean and building on top of it.
しかしパージ上で建造する方法の場合・ぐ−ノの動揺に
よる製作精度の低下等の問題がある。また分割してａ造
する場合には、分割体を洋上で合体する際に位置決めが
難しい上、分割体の動揺等の問題があシ、合体の作業性
が悪い欠点があった。However, in the case of the construction method on the purge, there are problems such as a decrease in manufacturing accuracy due to the movement of the guno. Furthermore, when dividing into an A structure, it is difficult to position the divided bodies when they are put together on the ocean, there are problems such as movement of the divided bodies, and the workability of combining them is poor.
本発明は上記した点に鑑みてなされたもので、ドック＋

建造する方法を提供しようとするものである。The present invention has been made in view of the above points, and is
The present invention aims to provide a method for easily and accurately constructing marine structures larger than 1].

ガーダ１１の両端１１ｏ。In the figure, 1 is a leg and 2 is a brat form.@In the method of the present invention, a part of the brat form 2 is not covered with a deck,
This is the exposed part 10, only the girder 11, and both ends 11o of the girder 11.
１１１を第２図に示すようにヒンジ結合し、ここで折畳

態を第１図（４）に示す。111 is hinged as shown in FIG. 2, and the marine structure is built in the dock in the folded state. This state is shown in FIG. 1 (4).

上で、露出部１０に甲板１２を張り、カンヌキ装置６を
取外して作業を完了する。Next, the marine structure is moved to the ocean, but at this time, it is preferable to fix it in the folded state using a cannula device B, as shown in FIG. 1(B) K. The receiver of this cannula device 6 is made rotatable so that it can be rotated by the same angle as the bending angle of the lever 11. After moving to the ocean, the cannula of the cannula device 6 is pushed out, and the cannula 11 is expanded from the folded state to widen it to the regular size. This state is shown in FIG. 1(C). Next, after fixing the cannula again, the deck 12 is stretched over the exposed portion 10, and the cannula device 6 is removed to complete the work.
上記作業において、露出部１０の甲板張り作業を除いて
、全てドック内で行えるため揺動等によシ製作精度が低
下することがない。また分割体はガーダによりヒンジ結
合しであるため位置合せの必要がない。In the above-mentioned work, all of the work except for the work of decking the exposed part 10 can be done inside the dock, so there is no reduction in production accuracy due to rocking or the like. Furthermore, since the divided bodies are hingedly connected by a girder, there is no need for alignment.
以上説明したように本発明法によれば、ドック中を超え
る海洋構造物の建造が精度良く比較的容易に行える効果
がある。As explained above, according to the method of the present invention, there is an effect that construction of a marine structure exceeding the inside of a dock can be performed with high precision and relatively easily.
