Claims (5)
- 浸水した構造部材がないか水中支持構造物を走査する方法であって、
前記水中支持構造物の一部をなす対象水中構造部材に向かって参照音波を送出し、その結果生じた反射音響−構造応答を検出することにより、予想反射音響−構造応答を設定することと、
前記対象水中構造部材に向かって、前記対象水中構造部材から離れて配置された音波源から点検音波を送出することと、
前記点検音波が前記対象水中構造部材に入射したことにより生じた反射音響−構造応答を検出することと、
前記検出された反射音響−構造応答を前記対象水中構造部材についての前記予想反射音響−構造応答と比較することと、
前記比較に基づいて、前記対象水中構造部材が浸水しているか否かを判定することと、を含む方法。 - 前記参照音波は、前記対象水中構造部材の外殻を透過するのに十分な周波数ではなく、前記点検音波は、前記対象水中構造部材の前記外殻を透過するのに十分な周波数である、請求項1に記載の方法。
- 前記音波源が、前記構造部材と接触しないように前記構造部材から離隔されたソーナーシステムである、請求項1に記載の方法。
- 前記水中支持構造物が海洋プラットフォームに関連する、請求項1に記載の方法。
- 前記予想反射音響−構造応答をあたかも前記対象水中構造部材が空気で満たされているかのように求めることと、前記検出された反射音響−構造応答と前記予想反射音響−構造応答との差を求めることと、前記差を閾値と比較することとを含む、請求項1に記載の方法。
