大型远洋货船最佳纵倾调整节能技术

Investigation of energy-saving by optimum trim for large ocean-going vehicle

对营运中排水量为五万吨级的寿光海轮，按不同的装载量进行了２０多种组合方案的首尾不同吃水状态下的船模阻力及自航试验；得出各种排水量下的最佳纵倾值，制成图谱和图表．本船及同类船按最佳纵倾值进行配载航运，取得明显的节能效果，可节省主机功率６％．

According to the different loadings,a series of tests of resistance and self-propulsion havebeen carried out under various conditions of draft for an ocean-going vehicle with 50,000 DWTnamed ″Shouguanghai″.The optimun trim value for each displacement had been presented byusing a series of special spectrograms and figures and have been applied to this vehicle onoperation in which a visible effect of the energy-saving is obtained,with about 6%of the mainengine power.
