Main Engine Power Estimation of Jack-up Based on Model Towing Resistance Test and CFD Calculation
In order to determine the main engine power of the self-propelled platform,the hydrostatic resistance of the plat-form model at design speed was studied with towing resistance test and CFD method respectively.The proportion of each main component of resistance was calculated.The main engine power of the actual platform was estimated.The test results and numeri-cal simulation results showed that the water flow accumulation and wave surface uplift are observed in front of the platform;the viscous pressure resistance of the platform is relatively large,accounting for a large proportion of the total resistance;there is a big error in calculating the resistance from the scale model to the real scale platform by using the two-dimensional method.A more reasonable estimate of the main engine power of the platform is given by using the real-scale CFD method.
