economics, taking into account the capital costs of installation, the current consumption, the
costs of maintenance, and the intended life of the structure.
Where hollow steel piles are plugged at their base with concrete or impervious soil it is
sometimes the practice to pump out the seawater and replace it with fresh water containing
a corrosion-inhibiting compound. The addition of sodium nitrite and sodium carbonate to
form a 2% solution can be used for this purpose. However, the need for this has been
questioned because an empty or seawater-filled pile contains little oxygen which is quickly
used up in the early corrosion process, leaving none to maintain the corrosion.
