Abstract

Single Point Anchor Reservoir (SPAR) platforms is a kind of floating platforms that are used in deep waters. This is a platform that are placed atop a huge hollow cylindrical hull with other end of cylinder descending to a water depth of about 300m.These are mainly used for deep water applications for drilling, production, processing, storage and offloading of ocean deposits. The Spar is modelled as a rigid body connected to sea floor by catenary mooring lines both loose and tight mooring that are attached to the spar at fairleads. Here nonlinear time domain analysis is done for response analysis at different wave angle to solve the dynamic behaviour of a moored Spar platform as an integrated system by iterative incremental Newmark’s Beta approach using NAOS software
