Potential profiles on SSCV after optimization for the different cases considered which represent the loading of the crane and the coating condition

In this paper published in the Journal Ocean Engineering a 3-D boundary element model of a semi-submersible crane vessel (SSCV) is combined with movement of anodes and adjustment of currents to optimize the anode quantity and location. The protection in four different states of the crane vessel representing the loading and coating condition were predicted and the simulation results indicate that the SSCV is well protected for the whole service life when the protective coating on the hull is repainted every seven years.

Optimized simulation results of FPSO: (a) final stage at 5°C and (b) final stage at 28°C.
In this study published in Corrosion, electrochemical tests were performed to obtain the carbon steel (EH36; UNS K12821(1)) cathodic polarization curves which contained environmental information under tropical (28°C) and arctic (5°C) environment model conditions, and the surface morphology was analyzed after the potentiostatic polarization test using scanning electron microscopy (SEM) and energy dispersive x-ray spectroscopy (EDS).
Based on the polarization data, a computational analysis was conducted to verify and optimize the CP design of the floating production storage and offloading (FPSO).
