MARIN has been awarded a contract by Prosafe Production Services Pte Ltd to perform a numerical study for the green water assessment of the Ningaloo Vision FPSO. Part of the study involved the design of a breakwater construction at the bow of the FPSO.
COMFLOW, a program for the numerical simulation of fluid flow, was used for the study. COMFLOW was initially developed by the University of Groningen but in close cooperation with MARIN, the methodology was later extended to encompass the calculation of green water loading on a fixed bow deck, including model tests for verification and the analysis of anti-roll tanks. A number of different designs were calculated and analysed to optimise the size and shape of the breakwater construction and to minimise the amount of green water flowing on to the deck in extreme weather conditions.

Results of the analysis show the amount of green water flowing on to the deck and pressure distributions at the breakwater construction. These results were then used by Prosafe to build the actual breakwater construction.
