Potable Water

Potable Water

(OP)
Is anyone aware of any regulations pertaining to where you can make water with a RO unit offshore?  For instance distance from land and or depth of water?

RE: Potable Water

Not sure what flag state your vessel is but for British registered vessels there is a 20 mile limit for the production of FW from low pressure evaporators or RO plants. Can extend further where estuarial pollution is a concern.

By law you should have a full set of M notices on board the vessel, If British and above 12m in length.

Look at MSN M.1214
4.1.3 and 4.1.4

RE: Potable Water

You can make potable water with a reverse osmosis unit onshore.  I suppose you are concerned with the environmental legeslation related to the discharge.  I don't know the answer.

Find ABS Design requirements at http://www.eagle.org/absdownloads/

Find the US Coast Guard regulations it Title 33 of the Code of Federal Regulations.

If on a US platform, check the 30 CFR 250 for the Minerals Management Service, Department of the Interior  --  Oil and Gas and Sulfur Operations in the Outer Continental Shelf.
