5.1.1 This Section contains local scantling requirements applicable to the weather-deck. All weather deck structure is to be evaluated according to Vol 1, Pt 6, Ch 4, 5.2 Requirements due to design pressures and Vol 1, Pt 6, Ch 4, 5.3 Additional minimum requirements.

5.2.1 The scantlings of plating and stiffeners on the weather deck are to be determined from the general equations given in Vol 1, Pt 6, Ch 4, 2 Minimum structural requirements, using the design pressures calculated according to Vol 1, Pt 5, Ch 5, 5.1 Weather and exposed deck pressure.

5.3.1 If the Complementary Rules are the Rules for Ships then the scantlings of plating and stiffeners are not to be less than those given in

• Pt 3, Ch 5 Fore End Structure and Pt 3, Ch 6 Aft End Structure of the Rules for Ships.
• Pt 4, Ch 1 General Cargo Ships of the Rules for Ships and the appropriate Chapter for the particular ship type.

5.3.2 If the Complementary Rules are the Rules for Naval Ships then the scantlings of plating and stiffeners are not to be less than those given in Table 3.2.1 Minimum structural requirements in Vol. 1, Pt 6, Ch 3, of the Rules for Naval Ships.

5.3.3 If the Complementary Rules are the Rules for Special Service Craft then the scantlings of plating and stiffeners are not to be less than those given in Table 3.2.1 Minimum thickness requirements in Pt 6, Ch 3 of the Rules for Special Service Craft.
