2. Depreservation measures
The following measures are to be implemented after a light or heavy preservation.
2.1 General work
• Establish the condition the engine was in before the preservation and disassembly
measures were taken: remove the protective plugs, covers, blanking flanges or other
sealant parts and any locking devices.
• Reconnect the engine to the plant if it has been necessary to seperate it.
2.2 Fuel system
• Depreservation is not required, even if the piping is still filled with the mixture used for the
preservation run.
• Restart the engine with this possibly in the system remaining mixture.
2.3 Lubricating oil system
• No depreservation measures are required.
• If the lubricating oil was drained, refill with the specified grade, see A4.05.08.nn.
2.4 Cooling water system
• Check the condition of the cooling water system and flush with fresh water if necessary.
• If chemical corrosion inhibitors are to be used and corrosion inhibiting oil has been
previously used, the entire system must be flushed with an alkaline solution, see
A4.05.09.02.
