Numerical investigation on mooring line configurations of a Paired Column Semisubmersible for its global performance in deep water condition

نویسندگان

چکیده

The advances observed in the offshore-renewable industry include recent development of a deep draft paired column semisubmersible platform developed for application on dry trees Gulf Mexico (GoM). These developments led to innovation Paired Column Semisubmersible by Jun Zou Houston Offshore Engineering. This paper presents detailed investigation mooring line analysis two different configurations hull (PCSemi). numerical research PCSemi coupled with lines was conducted, and model validated. Two were investigated: Chain-Polyester-Chain (CPC) Polyester-Polyester (PP) configurations, dynamic coupling frequency domain (FD) time (TD) using ANSYS AQWA Orcaflex. A comparative study is also investigated 2,438 m water depth at GoM, 16 catenary design. Results this gives natural period floating PCSemi's heave motion ranged from 21s 22s. Also, effect damaged increased tension other lines. Lastly, CPC configuration has smaller amplitude wave-frequency motions compared PP depicted global performance.

Numerical Investigation of Hydrate Dissociation Performance in the South China Sea with Different Horizontal Well Configurations

Based on the available measurement data and literature on the hydrate deposits of the South China Sea, a numerical simulation with a new dual horizontal well system has been carried out. Warm brine stimulation combined with depressurization is employed as the production method. Two horizontal wells were situated in the same horizontal plane and they were placed in the middle of the Hydrate-Bear...

Evaluating the Validity of Quasi-Static Analysis for Prediction of Vessel Mooring Line Forces

Quasi-Static analysis of moored vessels is vastly used for engineering designs, as a substitute to the numerical simulation of dynamic mooring analysis. Yet, the level of validity of the results of quasi-static analysis is a matter of discussion. In the present study, the validation of the assumptions behind the quasi-static analysis of mooring vessels is examined with application of a dynamic ...
