Steam must be generated from feedwater which is either treated with a chemical
oxygen scavenger or mechanically deaerated to a maximum dissolved oxygen
content of 15 parts per billion. Shore steam and condensed shore steam used
as feedwater must meet the above standards. The use of filming amines is
prohibited.
2.
[mu]S/cm = micro-Siemens/centimeter = micro-mho/centimeter. The lowest
reading on the shipboard conductivity meter is 40.
