The article discusses the design considerations for components which exhibit nonlinear phenomenon for an offshore floating platform housing energy and desalination plants. It gives an account of specific cases where such analyses were carried out. National Institute of Ocean Technology, MoES has been working in the area of developing large capacity offshore-based desalination plant. Various platform configurations were studied for housing the plant components. First case study deals with the numerical investigation of an inter-connection system between two floating platforms, semi-submersible and spar platform. Second case describes the methodologies for studying the effects of crucial vortex-induced vibration for estimating the fatigue life of the long-sea-conduit independently and when bundled.

Abstract


The article discusses the design considerations for components which exhibit nonlinear phenomenon for an offshore floating platform housing energy and desalination plants. It gives an account of specific cases where such analyses were carried out. National Institute of Ocean Technology, MoES has been working in the area of developing large capacity offshore-based desalination plant. Various platform configurations were studied for housing the plant components. First case study deals with the numerical investigation of an inter-connection system between two floating platforms, semi-submersible and spar platform. Second case describes the methodologies for studying the effects of crucial vortex-induced vibration for estimating the fatigue life of the long-sea-conduit independently and when bundled.
