1. Bottom (including boottop area):
Area = (2d + B) ´ Lpp ´ r d = draught maximum
B = breadth extreme
Lpp = length between perpendiculars
r = 0.90 for big tanks, 0.85 for bulk carriers, 0.70 – 0.75 for dry cargo liners
2. Boottop:
Area = 2h(Lpp + 0.5B) h = width of bootop
Lpp = length between perpendiculars
B = breadth extreme
3. Topside:
Area = 2H(Loa + 0.5B) H = height of topside (depth – draught)
Loa = length over all
B = breadth extreme
4. Weather deck (including upper decks on superstructure, foundation, hatches and top of deck houses):
Area = Loa ´ B ´ N Loa = length overall
B = breadth extreme
N = 0.91 for big tankers and bulk carriers, 0.88 for cargo liners, 0.84 for coasters
5. Practical Consumption Quantity( PCQ ) A=DFT x Areas ( sq.m) B=10 x VS% x Factor PCQ=A/B Factor: 0.7 normal作者: 爱我中华 时间: 2009-3-13 12:16
这个东西好像不错，船厂采购用得着！作者: 幼鹏 时间: 2009-8-17 16:54

这玩意，太简单了，不过还是比较实用作者: winerwhq 时间: 2011-11-19 21:06
