An investigation is made into the strength of ships’ derricks under static, as well as under dynamic loading conditions. This report presents the results of the static investigations. A study is made of the effectiveness of the stepped derrick constructed according to present-day practice as compared to the corresponding derrick of cylindric form.
The conventional construction method of stepped derricks with long inserted parts in way of the transitions proved to be objectionable rather than benificial; other methods of interconnecting tubes of different diameters were therefore tested. The results of the dynamic tests will be presented in Part II.
