Floating platform on sea with refuge device

Abstract

A platform floating on the sea surface and with the floating-sinking mechanism for avoiding huge wind and wave is composed of a platform body anchored to seabed via cables and such units under the platform body as floatage fixed unit, floatage adjustable unit and power system for controlling the floating or sinking of platform.

Description

technical field [0001] The invention relates to an ocean platform. Background technique [0002] The traditional deep-sea offshore platform design concept is a non-destructive design, such as being able to withstand storms or wave disasters that occur once in 50 years or 100 years. An ocean platform designed under this concept will suffer devastating damage once it encounters a natural disaster that exceeds its design limit. However, if the platform's ability to resist natural disasters is blindly improved, such as the design load return period is raised from 50 or 100 years to a higher level, the construction cost of the offshore platform will be greatly increased. Therefore, how to improve the ability of offshore platforms to resist natural disasters without increasing the construction cost too much has become a topic for scientific researchers. Contents of the invention [0003] Aiming at the problems existing in the existing design concept, the object of the present ...

Problems solved by technology

However, if the platform's ability to resist natural disasters is blindly improved, for example, the design load return period is raised from 50 or 100 years to a higher level, which will greatly increase the construction cost of the offshore platform.
