节约能源是一项长期的战略方针和基本国策,作为航运部门,减速航行是一项主要节能措施,应当着力去研究。我公司每年约短缺燃油8000吨,占年总耗油量的50％以上。公司领导决策:运输船舶减速航行,开经济航速。减速航行技术的内容主要包括下述两方面: 1、利用螺旋浆原理,即由式EHP=(D~(2/3)V3)/C_n表示的船舶所需马力与航速的三次方成正比,所以燃料也大致与航速的三次方成正比。由此
Energy conservation is a long-term strategic principle and a basic national policy. As a shipping department, slow sailing is a major energy saving measure and efforts should be made to study it. My company about 8,000 tons of fuel a year shortage, accounting for more than 50% of total annual fuel consumption. The company leadership decision-making: transport ships slow sailing, open economic speed. The contents of deceleration navigation technology mainly include the following two aspects: (1) According to the principle of propeller, the required horsepower of the ship represented by EHP = (D ~ (2/3) V3) / C_n is proportional to the cubic of the speed, So the fuel is roughly proportional to the third power of the speed. thus
