This standard specifies the approximate and numerical calculation methods for the natural frequencies of vertical and horizontal vibrations of the overall 2 to 5 nodes of the ship. The approximate calculation method of this standard is applicable to dry cargo ships with a length of 90 to 200m and oil tankers, bulk carriers, ore ships and container ships with a length of 90 to 300m. The numerical calculation method is applicable to oil tankers, dry cargo ships and bulk carriers with a length of 20 to 300m. , ore ships and container ships.
