dylant,
the answer is GRP or any other GRP like materials. Currently we are using it onboard of our vessels for ballast systems. On the other hand, while designing a pipling converying high conductive liquids, you should consider corrosion. Sometimes even SS is not a good solution for such...
Truckdriver2,
In our vessels we always face that problem and we solve it as follows;
a round ventilation channel bolted on top of the fan. the outer shell of the channel must be of thin galvanized CS plate with aproximately 5 mm holes all over it and inner shell of the channel is the same. the...

Thanks for the reply, I knew that the wind factor is already taking force in the calculation of Intact Stab. but what i m informed is a new rule which i m not clear about it.
Anyway thanks for your time.

Is it true ? If it is so , then which rule is...
