    Could you please tell me how to calculate the survival draft for a floating platform?
    I will also appreciate if you have a sample stability booklet for an offshore platform.

    Hi, The vessel looks similar to this. It has 6 vertical columns and two pontoons.

    Ok, now what do you mean by "survival draft"? Draft at Instability? Loading Conditions? Stable Draft after Damage? Draft needed to have a 99.xxx percent chance of surviving a Beaufort/NATO SS y storm in zzzz feet of water? There are lots of ways to sort this and thousands of different answers depending on the case used.

    Leopard. You are posting questions that appear to be homework. For a Naval Architect working at a shipyard, like you claim to be, the calculations should obvious. As was told to you before, regulating bodies, laws, class regulation, etc. will give you the answer. However, you need to ask the right questions. For example, a sample booklet from China is likely to be useless for the EU. Also, instead of posting an image that is a free download, post an image of the platform you are referring to; that is assuming such platform actually exists.
