Beware of fuel oil quick closing valve deficiencies

The Bahamas Maritime Authority (BMA) has published a technical alert aimed at highlighting some major deficiencies related to fuel oil quick closing valves, which it has observed during Port State Control inspections. These deficiencies are considered of importance and often lead to detention.

Quick closing valves are fitted to oil tanks so that in the event of a fire they can be safely closed from a remote location to stop the supply of fuel to the fire. These valves may be operated remotely by pull wires, hydraulics, compressed air, etc.

Recently, BMA has observed that quick closing valves have been modified or intentionally blocked to prevent them from closing. This practice has potentially catastrophic consequences in a fire emergency.

In view of this, BMA recommends:
– Quick closing valves are to be regularly maintained and tested. The inspection, maintenance and testing of quick closing valves is to be incorporated in the ship’s planned maintenance system.
– Quick closing valves should not be intentionally blocked or “gagged” in the open position to prevent operation. In cases where, temporarily, it is necessary to block a particular valve during testing or maintenance (e.g. to prevent loss of power or propulsion), care must be taken to return the Bahamas Maritime Authority blocked valve to operational condition immediately after completion of testing or maintenance.
_ All owners, managers & Masters of Bahamian ships should ensure that all relevant crew members are familiar with the operation of the quick closing valves fitted to their ships.
