7.1.1 The requirements given in this Section apply to the arrangements of primary structure supporting the peak framing, the scantlings of the bottom structure, framing, aft peak bulkhead, transom and swim end.
7.2.1 The bottom of the peak space is generally to be transversely framed with arrangements and scantlings as detailed in Pt 3, Ch 5, 3.3 Single bottom – Transverse framing.
7.2.2 When the ship is self-propelled, the thickness of the floors in the aft peak is to be increased by 15 per cent and the floors are to be suitably stiffened.
7.2.3 Where the bottom in the aft peak is longitudinally framed, the arrangements and scantlings are to be as detailed in Pt 3, Ch 5, 4.3 Shell longitudinals; additional bottom transverses are to be fitted in way of rudder posts, propeller posts and shaft brackets if fitted.
7.3.1 The framing in the aft peak may be either transverse or longitudinal. The scantlings and arrangements of the framing are to be as required in Pt 3, Ch 5, 4.2 Shell framing and Pt 3, Ch 5, 4.3 Shell longitudinals respectively.
7.4.1 The position and height of the aft peak bulkhead and the scantlings are to be in accordance with the requirements of Pt 3, Ch 7 Bulkheads. The plating is to be locally increased in way of the sterntube gland.
7.5.1 Where a transom is arranged in the aft ship, the scantlings and arrangements of plating and stiffening are to be as detailed in Pt 3, Ch 5, 2 Hull envelope plating and Pt 3, Ch 5, 4 Shell envelope framing respectively.
7.6.1 The draught for calculation of the structural members may be taken as the actual draught in way of the respective member.
7.7.1 Where the ship is intended to be pushed, the stern arrangement is to comply with the requirements of Pt 3, Ch 5, 4.6 Stem arrangement for pushing purposes for the stem arrangement. The forces P 1 or P 2 are to be determined applying a value of P p(H p) based on the intended service conditions.
