Results Comparison of Computer Simulation, Model Test and Offshore Installation for Wandoo Integrated Deck Float Over Installation

摘要

Computer simulation and model tests were used to develop and evaluate the Wandoo B integrated deck float over installation design. The design included moorings, fenders, ballast system, mating point and supporting point mechanisms.The mooring line dynamic loads, impacts between barge fenders and concrete gravity sub-structure (CGS) shafts, mating point impacts and support point impacts were simulated in the time domain.Model tests were used to check the design parameters and computer simulation results. Decay tests were used to estimate system damping for the final computer simulation.Mooring line tensions, barge motions and environmental conditions were monitored during the integrated deck float over installation.A comparison of the computer simulation, model test and field installation results are given in this paper. Possible improvements to the computer simulation, model tests and the integrated deck float over installation design are highlighted.
