Guidance for precautions against freezing of fire mains

In considering the problem of the freezing of fire mains in vessels, the possible solutions of the problem are:

(a) the re-circulation of a sufficient quantity of water, if necessary from a heated reservoir;

(b) the use of a dry system of fire main such that there is no water in the line until a control valve in an accessible space protected from frost (on the rising main) is opened;

(c) the use of a leak-off system in which a sufficient quantity of water is allowed to escape from the ends of the fire main; and

(d) the use of a heating system whereby steam, electrical or hot water heating is used to maintain the water in the fire main in a liquid state. The use of insulation may be incorporated in this system in order to avoid heat loss. Heating may also be effective in reducing the quantity of circulating water referred to in paragraphs (a) and (c) of this recommendation.

In any case, the provisions of effective drainage to the fire main and the proper use of the drains by the crew is imperative if freezing of the fire main is to be avoided in low ambient temperatures.
