This is section 10 of 15. We are slowly getting there.</div><div><span style="font-size:10pt"> In addition to the following rules, the propulsion & steering systems are subject to G.L. rules for</span></div><div>machinery installations & the rudders to G.L. rules on hull structures.</div>
<div> The motors are to be designed to be used continuously.</div><div> Propellers need shielding.</div><div> Electronic motor controllers shouldn't fail so the motor continues running, & the motors need to </div>
<div>be capable of manual control.</div><div> The propulsion equipment needs to be fitted with indicators & alarms to guarantee safe operation.</div><div> Effective reverse thrust for braking has to
be provided.</div><div> The stress in the rudder stock can't exceed .5 of the yield stress.</div><div> Independent submersibles (operated off shore without support ship), need to be equipped with</div><div>auxiliary steering gear (bit foggy about what this means)</div>
<div> The steering gear needs to be able to move the rudder from 35 degrees one side to 30 degrees the other</div><div>within 28 seconds (how's that for nit picking)</div><div> If horizontal rudders are a necessity on your sub, they need to have an alternative power supply that can</div>
<div>be operated from the control stand. The "slewing" movements of motors used for maneuvering are also subject</div><div>to the above requirement.</div><div> There needs to be rudder position indicators & indicators to signal any failure of the steering gear.</div>
<div> There are rules for dynamic positioning that are required for
some operations, but probably don't concern us</div><div>& their equipment is examined on a case by case basis.</div><div>Regards Alan</div><div><br clear="none"></div><div><br clear="none"></div><div> </div><div>
