Abstract
Description
本願は、2010年6月30日に出願された米国特許仮出願第61/359,923号(発明の名称:COMPLIANT DECK TOWER)の権益主張出願であり、この米国特許仮出願を参照により引用し、その記載内容全体を本明細書の一部とする。
さらに、上述したように、先行技術の構造体の中には、得ようとする離調の大部分を提供する水平剛性を隔離するために垂直荷重、及びかくして垂直加速度を利用しているものがある。本発明の実施形態では、復元力は、構造要素の軸方向剛性と曲げ剛性又はこれら両方により提供され、それ故、垂直荷重及び垂直加速度とは実質的に無関係である。
Claims (14)
- 海洋掘削及び天然資源の産出に用いられる応従性デッキタワーであって、デッキ構造体と、前記デッキ構造体から海底まで延びる下部構造体とを有し、前記下部構造体は、環境に起因する力によって前記下部構造体に加えられるエネルギーから前記デッキ構造体を隔離する連結部によって前記デッキ構造体に連結されている、タワー。
- 前記連結部は、自在継手を含む、請求項1記載のタワー。
- 前記連結部は、前記下部構造体内に固定され又は前記下部構造体に固定された1本又は2本以上の細長いビームを含む、請求項1記載のタワー。
- 前記連結部は、自在継手と、前記下部構造体内に固定され又は前記下部構造体に固定された1本又は2本以上の細長いビームとを含む、請求項1記載のタワー。
- 前記連結部は、構造用撓み継手を含む、請求項1記載のタワー。
- 前記下部構造体は、前記海底上のベース構造体まで延びている、請求項1記載のタワー。
- 前記連結部は、前記デッキと前記下部構造体との間で全体として水平の平面上に配置された1つ又は2つ以上の支承体を含む、請求項1記載のタワー。
- 前記支承体は、支承体支持フレームに取り付けられている、請求項7記載のタワー。
- 前記下部構造体は、少なくとも1本の支持脚を有し、前記支承体は、前記少なくとも1本の支持脚の頂部に取り付けられている、請求項7記載のタワー。
- 下部構造体と、支持構造体の頂部で支持されたデッキとを有する沖合構造物であって、前記デッキ及び前記支持構造体が地震の水平力に応動して互いに対して水平に動くことができるよう前記デッキを前記支持構造体に対して支持する免震構造体を有し、前記デッキは、あらかじめ選択された水平距離を超える前記支持構造体に対する前記デッキの水平運動を阻止するように前記支持構造体に連結されている、沖合構造物。
- 前記免震構造体は、前記デッキと前記下部構造体との間に設けられた複数個の摩擦支承体を有する、請求項10記載の沖合構造物。
- 前記デッキは、前記あらかじめ選択された水平距離を超える前記デッキの側方運動を阻止するために前記下部構造体の上方部分によって拘束されるように位置決めされる下方区分を有する、請求項10記載の沖合構造物。
- 前記免震構造体は、前記デッキを支持するようになっており、前記免震構造体は、更に、前記デッキが地震の水平力に応動して前記下部構造体に対し側方に回動することができるようになっており、前記免震構造体は、前記下部構造体に対する前記デッキの水平運動に抵抗する傾向のある垂直偶力を前記デッキに加える手段を有する、請求項10記載の沖合構造物。
- 地震による振盪及び震動に対して安定化されると共に補剛されている沖合プラットホームであって、少なくとも1つの水平レベルを含む作業デッキ構造体と、前記作業デッキ構造体に取り付けられた少なくとも1本の関節連結支持脚と、前記少なくとも1本の関節連結支持脚に取り付けられると共に海域の底部に取り付けられ又は海域の底部中に部分的に沈められた下部構造体とを有し、前記少なくとも1本の関節連結支持脚と前記下部構造体との間及びオプションとして前記作業デッキと前記少なくとも1本の関節連結支持脚との間の取り付け箇所は、自在継手又は構造用撓み継手を更に含む、沖合プラットホーム。
