载重线公约是否适用于半潜平台

人在糨糊飘

如题所示，载重线公约内容感觉就是给运输船用的，半潜平台是否适用呢？如果适用，位置1和位置2怎么定义？

感觉不适用，应该有其他规范去定义半潜船吧，我也没搞过，学习学习。

5.3.6 For the first tier on the freeboard deck, the requirements as for position 2 in the ICLL apply with
respect to openings, sill heights, coaming heights and weathertight closing appliances.
5.3.7 For the second tier, weathertight closing appliances are required, but sill or coaming heights may be
omitted.
5.3.8 For third tier and above, load line requirements will not apply.

这几条是否能应用于半潜平台呢？

这是半潜的要求。 读下规范吧 不知道你是哪家船级社。

当然适用了！但不是“船舶观念”的适用，而是整体性的适用，即载重线公约最前面部分的总体要求（强度、稳性......等）满足相关的要求就可以了。
也就是说，如果在最深吃水时，各方面都满足要求了，以干舷甲板为基准点确定位置1、2，比船舶好满足多了。

感谢解答。我也是这么理解的，但是我发现有的半潜平台位置1上面的门槛高度并不满足载重线公约的要求。

如果干舷足够大，开口离开最深吃水很高，可以减免的吧？去查查IACS的解释看。

3.7.1 The requirements of the 1988 LL Protocol, including those relating to certification, should apply to all units and certificates should be issued as appropriate. The minimum freeboard of units which cannot be computed by the normal methods laid down by that Protocol should be determined on the basis of meeting the applicable intact stability, damage stability and structural requirements for transit conditions and drilling operations while afloat. The freeboard should not be less than that computed from the Protocol where applicable.

  3.7.2 The requirements of the 1988 LL Protocol with respect to weathertightness and watertightness of decks, superstructures, deckhouses, doors, hatchway covers, other openings, ventilators, air pipes, scuppers, inlets and discharges, etc., should be taken as a basis for all units in the afloat condition.

不要问，去看公约的原文
