6.1.1 Where it is proposed to use wheeled vehicles such as fork lift trucks and
mobile cranes on deck structures, the deck plating and the supporting structure are
to be designed on the basis of the maximum loading to which they may be subjected in
service and the minimum gross scantlings are to comply with the requirements of
Pt 3, Ch 9, 3 Decks loaded by wheeled vehicles of the Rules for Ships. In no case,
however, are the scantlings to be less than would be required by the remaining
requirements of this Chapter when the deck is considered as a weather deck or
storage deck, as appropriate.
