    Thanks for reply.

    Above equation is about design force on the cargo during dry tow of self propelled heavy lift transports.

    As i understand, Force on the cargo during dry tow is cargo weight * acceleration of the vessel due to ship motions. (F acc)

    but above equation consider many other thins not only F acc.

    I can not be sured above equotation is correct or not because I can see equation only some documents not official document such as Noble Denton etc.

    If give me any information or guide, it will be much helpful.
