吨位计算

jbw

请问以下
不装货物的船还要算净吨位吗？
那个总吨位公式里面的那个总容积包括上建的容积吗？

The International Convention on Tonnage Measurement of Ships, 1969 was adopted by IMO in 1969.The Convention mandated a transition from the former measurements of net register tons (nrt) and gross register tons (grt) to net tons (NT) and gross tons (GT) . It was the first successful attempt to introduce a universal tonnage measurement system.
The rules apply to all ships built on or after July 18, 1982.Ships built before that date were given 12 years to migrate from their existing tonnage to use of NT and NGT.The phase-in period was provided to allow ships time to adjust economically, since tonnage is the basis for satisfying manning regulations and safety rules.Tonnage is also the basis for calculating registration fees and port dues. Both NT and GT are obtained by measuring ship's volume and then applying a mathematical formula.Net tonnage is based on "the moulded volume of all cargo spaces of the ship where gross tonnage is based on "the moulded volume of all enclosed spaces of the ship"."In addition, a ship's net tonnage is constrained to be no less than 30% of her gross tonnage.

我觉得所有的船都要计算净吨,
1.净吨的公式中包含人数的因子.(12人以下无),间接的说,人也是货物啊.和船舶功能(function)相关的都可以成为货物吧？
2.净吨不少于总吨的30%，所以净吨也是船舶设计的一个参数。
3.这个convension是对所有船舶应用的，没有说明船舶的种类，只和建造时间相关。

总吨，
从keel到funnel之间的所有围壁处所都要计算在内的吧。

纯属学习性回帖，发现自己真是什么都不懂啊。被资本家蚕食了，公司分工太细的结局就是把我变成一个螺丝钉只知道自己做的那一小小部分的一小小块。

楼下请给我批作业，谢谢
