Description
・SPAR型フロータは、細長い幾何学的形状と、構造全体の重心を最大限に低くし、安定性をもたらすような顕著なバラストを有することを特徴とする。
・バージ型フロータは、非常に広く、喫水の浅い支持構造である。バージ型フロータの安定性はその広い喫水面によってもたらされる。しかしながら、この種の支持構造は波動の影響を非常に受けやすい。
・TLP(緊張係留式プラットフォーム)型支持構造は、構造安定性をもたらす緊張ケーブルによって海底に係留される特有の特徴を有する。
・半潜水型フロータは、剛性を付与するアームによって連結された少なくとも3つのフロータからなる支持構造である。これらの支持構造は、概して変位量が少なく、喫水面慣性が高く、それ故、構造の安定性に関して十分な復原力を提供する。さらに、この種のフロータはバージよりも波動の影響を受け難い。
本発明による安定化システムを備えたフローティング支持体(フロータ)の性能を評価することで、一方で安定化システムとフロータとの相互作用を表し、他方でフロータと波動との相互作用を表すことができる。この運動方程式を得るためにラグランジュ的アプローチが用いられる。その一般形態は次式によって与えられる。
