Nevertheless, low-load operation at engine load below 15% of the nominal rating is permitted for max.
100 hours. In order to avoid inadmissible oil carbon and/or carbon particle deposits in the engine, it is rec-
ommended to carry out a cleaning cycle for at least 20 minutes after extended low-load operation periods.
During the cleaning cycle, engine speed (power) must be increased step by step until all exhaust turbocharg-
ers are running. The figure illustrates the basic principle for increasing speed/power during the cleaning run.
After longer periods at idle/low-load operation (> 60h) followed by load imposition, avoid shedding load im-
mediately (< 10 minutes ) to prevent the risk of damaging the catalyst substrate.
SOLAS – Fire safety requirements
Installation locations of SOLAS shielding (→ Page 121).
Special connections
In case of leakage, the following connection types are spray-protected even without a cover and have been
confirmed compliant with SOLAS by GL and DNV.
Plugs and sensors (a)
Screw plugs (4) are either sealed with copper sealing rings (1) as per DIN or O-rings (ISO).
The fluid must first pass the thread in case of a loose threaded union or faulty sealing ring (1).
The pressure is so greatly reduced by this and the faulty sealing ring (1) that any leakage is not under pres-
sure.
Plug-in pipe connection (b)
Design precludes lateral spray as the point of separation is shielded by the sleeve (3).
Only seepage along the pipeline is possible whereby the pressure is greatly reduced by a faulty O-ring (2).
The connection is confirmed as being SOLAS-compliant by DNV and GL.
