Description

가요성 연해 플랫포옴(Flexible Offshore Platform)
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 "리이드"라고 불리우는 400m높이의 플랫포옴의 정면도이고, 제2도와 제3도는 자연주기가 각각 35초와 4초일때 컬럼의 변형모양을 나타내는 것이다.

Claims (6)

  1. 해저면에서 플랫포옴을 고정하는 기초구조물, 기초구조물에 고정된 플랫포옴 전체높이의 반이상을 차지하는 가요성컬럼, 가요성컬럼상부에 고정된 감수형스테빌라이져 및 스테빌타이져와 플랫포옴의 덱크를 또 하나의 컬럼으로 연결구성함으로써, 스테빌라이져의 적절한 질량과 스테빌라이져에 저장된 물의 질량에 의하여 형성된 거대한 질량에 기인한 스테빌라이징효과와 플랫포옴 그 자체가 파도, 바람, 해류등에 기인한 작용에 대하여 반작용응력을 일으킬 수 있도록 강성을 가진 가요성 연해 플랫포옴.
  2. 제1항에 있어서, 스테빌라이져는 플랫포옴의 중량을 보상하기위해 부력고를 포함한다는 것.
  3. 제1항에 있어서, 스테빌라이져는 스테빌라이진 효과에 기여하는 대량의 물을 저장하는 개방돈 쉔을 포함한다는 것.
  4. 제1항에 있어서, 스테빌라이져는 액체 또는 다공성고체를 저장하는 밀폐된 탱크들을 포함한다는 것.
  5. 제1항에 있어서, 컬럼의 가요성과 덱크, 컬럼, 스테빌라이져의 질량의 분배 및 스테빌라이져에 의하여 유체역학적으로 채워지거나 저장된 물의 질량들은 플랫포옴의 기초자연 휨 주기가 큰 파도의 기초자연휨 주기보다 큰 항상 20초 이상이라는 것.
  6. 제1항에 있어서, 컬럼의 가요성과 덱크, 컬럼, 스테빌라이져의 질량의 분배 및 스테빌라이져에 의하여 유체역학적으로 채워지거나 저장된 물의 질량들은 플랫포옴의 두번째 휨 진동상태의 자연주기가 가장 큰 파도의 자연주기와 비교시 작은 항상 10초이하라는 것.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
