Monitoring hold bilges during loaded passage of a bulk carrier

Many cargoes contain moisture that may accumulate at the bottom of the cargo hold and drain towards the hold bilges, raising the bilge level and possibly triggering the high level bilge alarm if fitted. This can also occur if there is any leakage into the cargo holds through hatch covers or from elsewhere.

If the ship is loaded with the same cargo in all holds and all the bilges indicate increased soundings, then it can be said with certainty that the water in the bilges has drained from the cargo. For example, a cargo of coal may contain up to 1% of its weight as moisture, which will drain into the bilges. Otherwise, it may indicate a particular leaking hatch cover or other leakage, which should be investigated

It is important to pump out water accumulated in the bilges to avoid:

The bilges should be left nearly dry so that any other leakage into cargo holds can be detected by a rise in bilge level.

The handling of bilge water should be clarified in the charterparty or otherwise by charterer's instructions. As the moisture may amount to about 1% of the weight of the cargo, the quantity of cargo available for discharge would also be less. It is conceivable that charterers may try to forbid discharging of bilges, in which case advice should be sought from owners/ managers.

Bilges should be discharged overboard after keeping the pollution aspects in mind, ensuring that the quantity of water pumped from them is recorded in the sounding book or charterer's form. If bilges are discharged, a record should be kept in a format .

Always accessible bilge well

Bilge well – A sump to which bilge water drains. It is important to arrange bilge wells in the way enabling permanent access and possibility of cleaning even when holds are loaded.
