Section 3 Hull Structures

301. General

Hull structuress are to be in accordance with this section in addition to relevant requirements in

Ch 3, Sec 2.

302. Work Deck

1. Reinforcements

The work deck is to be strengthened for the specified design loads and non-uniform loadings are to be specified. The strong points, if required, are to be situated, as far as practicable, on crossings of bulkheads and web frames. All deck stiffeners are to be double-continuous welded.

2. Arrangement

(1) It is recommended that fuel tanks are not located directly under the working decks, where hot works would be carried out, unless a void space, hold, store, cofferdam or water ballast tank forms a separation space between the working deck and fuel tank.

(2) The working deck, as far as possible, is to be kept unobstructed, clear of engine room intakes and exhaust from tank vents and mooring equipment. Tank vents, mooring and deck access pro-

visions are preferably to be grouped in way of the aft deck, boom rest and/or forecastle.
