The Liberian Administration has released an advisory is to inform interested parties how to comply with the recent focused trend of inspection of machinery spaces by various Port State Control (PSC) regimes.
A ccording to the Administration, there has been an increased focus on the proper operation of firefighting equipment and cleanliness of machinery spaces. Specifically, the following items are consistently noted by Port State Control Officers: Marine Quick Closing Valve
The Liberian Administration encourages owners, operators and their masters and chief engineers to take this Marine Advisory into account during the normal operation of their vessels and ensure the following steps and checks are included in the proper conduction of the engineering watches and planned maintenance:
#1 Engine room water mist systems
Engine room water mist systems must be readily available for immediate use and in good working order. Activation switch on the system control panel must be set on “Remote” or “Automatic.”
Precaution shall be taken to prevent the nozzles from becoming clogged by impurity in the water, regular checks must be carried out to identify corrosion of piping, nozzles, valves and pump.
Quick closing valves are positive shut off valves that are designed to isolate oil tanks in the event of a fire and also prevent fueling of a fire in circumstances where system piping and components are compromised.
Such valves must always be free to operate, manual wires activators and/or hydraulic systems must be kept under close examination and tested regularly. Under no circumstance shall a valves operation be hindered by fitting wedges or wires to preclude the activation.
A maintenance plan should be in place, including technical manuals containing diagrams and information that describe the system components, required spare parts, operation, maintenance and repair.
All engine department personnel should be able to identify the location of each valve, the respective remote closure and how to close them locally and remotely in an emergency.
Insulation lagging should be inspected regularly. Inspection should include looking for signs of cracking, distortion or any damage or signs of a hot spot. Evidence of leaks shall be acted upon with celerity and corrected to prevent possibility of fire.
Equipment hot spot should be identified and insulated in order to prevent the creation of areas that could ignite a fire in case of sprays or leaks in the system.
Fuel and lubricant leaks can easily lead to a fire or an explosion due to their highly flammable nature or create pollution and hazardous situations. Leaks from fuel pumps, main engines, generators and steering gears shall be corrected immediately.
The administration notes that adhering to a robust preventative maintenance system ensures that repairs are carried out prior to the development of leaks that can lead to fires, pollution and are a common reason for ships to be detained by port state control. Following areas have been known for leaks and oil accumulation:
Furthermore, fixed gas detection systems are vital to ensure that the engine room and cargo block are not at risk for cargo vapors that could pose harm to the crew, ship and the environment.
Additionally, the proper operation and testing of the system demonstrates that the system is functioning as designed.
Finally, using and having the appropriate span gas on board demonstrates that the crew is actively verifying that the system is operational. Rectification and prevention of these situation is vital for safe operation of any vessel.
