2 Design Load Sets

2.1 Application of load components

2.1.1 Application

These requirements apply to:

Plating and stiffeners along the full length of the ship.
PSM outside the cargo hold region.

2.1.2 Load components

The static and dynamic load components are to be determined in accordance with Ch 4, Sec 7, Table 1.

Radius of gyration, k_r, and metacentric height, GM, are to be in accordance with Ch 4, Sec 3, Table 1 and Ch 4, Sec 3, Table 2 for the considered loading conditions specified in the design load sets given in Table 1.

2.1.3 Design load sets for plating, stiffeners and PSM

Design load sets for plating, stiffeners and primary supporting members are given in Table 1.

In addition, the design load sets for primary supporting members of bulk carriers with length L less than 150 m and of oil tankers within the cargo hold region are given respectively in Pt 2, Ch 1, Sec 4, [4.2] and in Pt 2, Ch 2, Sec 3, [1.2].

(1) Forbulk carrier BC-A and BC-B, full load condition means ‘homogeneous heavy cargo’. (2) Forexternal shell only. (3) P_ex is to be considered for external shell only. (4) Not to be applied to bulk cargo hold assigned as ballast hold. (5) Bulkcargo hold only. (6) FD-1 and FD-2 are not applicable to external shell and corrugations of transverse vertically corrugated bulkhead separating cargo holds. Requirement in flooded conditions of transverse corrugated bulkhead are given in Pt 2, Ch 1, Sec 3, [3]. FD-1 and FD-2 are to be considered for strength deck whenever applicable. (7) Minimum draught among heavy ballast conditions is to be used. (8) Distributed or concentrated loads only. Need not be combined with simultaneously occurring green sea pressure.
