[求助] 求翻译一段话~~

If the vessel motion in DeepC depend on the vessel response calculated in Wadam/HydroD, the mass and mass distribution in HydroD as well as the static mooring line tensions should be as accurate as possible. This is relevant if the vessel motion to be calculated in DeepC is based on RAOs produced by Wadam (simplified vessel motion), or if the vessel motion shall be calculated as a full coupled vessels/lines motion analysis which also include second order mean drift, sum frequency, or difference frequency - forces. If not,then it is only the draft of the vessels that is of importance when running HydroD. As long as the draft is "correct", added mass, potential damping and first order excitation forces will be correct even if the mass is not (mass data given to HydroD can be overridden in DeepC)
