Section 8 Waterjets

801. Design loads

1. The following loading conditions are normally to be considered.

(1) Maximum ahead thrust

(2) Maximum side forces and moment

(3) Maximum external forces and moment in astern condition

2. The aft supporting area is to be adequately strengthening to sustain the design loads defined in Par 1.

802. Duct design

1. Tunnel supporting structures of shaft bearings are to adequately strengthening to main structures.

2. The tunnel plate thickness is to

be at least 1.5 times the rule requirements for shell plating and

adequately strengthening to avoid the large panel.
