Q.What is proper procedure to prepare steam lines on deck for heating cargo in cargo tanks?

- Carry out a pressure testing of tank heating coils to find out any leak in the line.

- Ask Engine room to open the deck steam just enough to warm up the line.

- During the warming up time open all the drain valves on deck to flush out any water in side the pipe line.

- Open steam trap valve to get rid of any condensate

- Once the pipe lines are suffciently warmed up close the drain valves and open the return lines valve.

- Ask E/R to slowly increase the steam flow and observe for any steam hammering in the pipe lines .

- If every thing feels satisfactory then increase the flow of steam depending upon the consumer steam coils.
