Area of Research

FPSO platforms facilitate the Production, Offloading, Storage operations in the offshore field. In the past, most of the FPSO systems were adopted for shallow water depth only. The need for effective production and utilization of remote oilfields has been moved towards deep and ultra-deepwater depths. Still, studies on their performance in harsh environment prevailing in the east coast of India is limited. Usually, FPSO's are ship-shaped and can be secured to the seabed by various mooring systems. But has many drawbacks like stability issues, vertical bending moment due to abnormal load, etc. The operational wave beyond which the spread mooring of the FPSO vessel is to be decoupled is to be quantified for reducing the coupling and decoupling operation. The steel lazy wave riser (SLWR) system is more suitable and feasible to reduce the dynamic effect.

The main objective of this research project is to explore all possible deepwater offshore systems comprising deepwater riser and mooring systems for suitable deep and ultra-deepwater conditions. The laboratory environment under operational and severe sea state with spread moored FPSO in directional waves can be performed in a 30 x 30 x 3 m wave basin at the Department of Ocean Engineering, IIT madras.
