E.8 Conservation of the generator (long operation interruption)
E.8.1 Measures for preparation of winter storage
1. Rinse seawater circuit with an anti-freeze solution, if this contains a corrosion protection solu-
tion. The seawater intake must be stopped at the seacock. The anti-freeze protection mixture
is to be sucked up from a container by means of a hose connection. The cooling water mixed
with the exhaust gases should be fed back to the suction container. The circuit must be kept
upright some minutes to ensure the anti-freeze protection mixture reaches all parts of the coo-
ling system.
2. The anti-freeze mixture concentration in the internal cooling circuit must be checked with a
suitable measuring instrument. The concentration must be adequate for the lowest expected
temperatures.
3. Clean seawater filter and check seal.
4. Check seacock for practicability. And spray with a corrosion protection oil from the inside or
lubricate with acid-resistant grease.
5. Check all hoses and hose connectors for good condition. The rubber hoses are very sensitive
to environmental influences. They can deteriorate quickly in environments with dry air, light oil,
fuel fumes and increased temperatures. The hoses must be checked regularly for elasticity.
The hoses must be renewed once in the year in particular operating situations.
6. Doubly check the hose connections at all seawater valves, and if possible protect them with
double hose clamps.
7. Dismount the cooling water pump impeller and check for wear. The impeller may not remain in
the pump. It must be greased with Vaseline and be kept in a dark place. It can be re-integrated
again into the pump, during the spring, if it is in good condition. The impeller is a wearing part,
and it is recommended that it is always renewed in the spring, depending upon the number of
hours the generator has been running.
8. Control of the vent valve at the seawater inlet. A vent valve is always necessary, if the genera-
tor is installed below the waterline. The vent valve must also be regularly checked during the
season. The vent valve should always be disassembled, checked and greased during winter
storage. Hardened or dirty parts are to be replaced.
9. Check water lock: If the generator were rinsed with an anti-freeze mixture, the anti-freeze mix-
ture can escape from the water lock. If the generator were rinsed with fresh water, the water in
the water lock must be drained. Otherwise there is a danger of the collector being destroyed
by ice through expansion.
10.Check the exhaust/water separator for leakage and whether the hose connections at the lower
surface of the separation unit are in normal condition. (in the case of extremely sulphurous
fuels, it is possible that high-grade steel tube ends are attacked.)
11. Check all construction units of the generator inside the sound cover for leakages. If there are
traces of humidity in the sound cover, the cover must be dried. Furthermore, the cause for
damp must be searched and eliminated.
