Subject: ER Ventilation Filters
Please find attached photo of modification on ER ventilation system which is found to effective in reducing the dust into ER.Pl revert back with feasibility and materials requirement to carry out the same on your vessel.
Thanks and Best Regards

Sub : XXX/ INTELLLIGENT CORRUGATED AIR FILTER
Attach: ENG VENT FANS AND DUCTING 003.JPG
I CALL THIS AN INTELLIGENT FILTER --
FOR CORRUGATION HAS INCREASED ITS EFFECTIVE SURFACE AREA BY > 100% --
this " thumbs up " is NOT for engine room cosmetics at all --
it is for sustaining PRINCIPLES OF ENGINEERING --
-- if you see latest model vacuum cleaners -- they all have gone for the corrugated filters , instead of saggy air bags --
most problems in internal combustion machinery in engine room is due to lack of air volume in the cylinder.
a look at the smoke emission from the funnel clearly shows when air is starved.
it has become STYLISH and TRENDY to put THICK pad filters on ME and AE turbochargers --
visiting superintendents always give good reports for such mindless acts , even in pressurized engine rooms with funnel door and skylights open --
when i went back on XXX the second time ( after 3 years of delivery ) -- the engine room had developed amazing engineering problems -- vital machinery would just break into pieces.
i joined at XXX ( with an active volcano spewing ash , 1 mile off the berth ) - --
-- on departure, as soon as the pilot was dropped, i called up chief engineer ( all know who this is ) and told him to remove all filters on ER vents --
since he was NOT willing to remove it , and was ready to fight over it -- i had to threaten him with DISMISSAL WITHOUT NOTICE at next port ( i was dead serious !!) --
--and then it was done el pronto -
the ship had a VAST CRITICAL RANGE between half ahead and full ahead of main engines --
-- excessive time to MOVE THROUGH this banned range-- caused excessive vibrations -- the funnel stack vibrates like crazy --
if the boiler stack vibrates -- the downcomer caused the boiler circ pump shaft to vibrate -- the causes the bearings to disintegrate and pump shaft to break--
this was a recurrent problem. all were on a wild goose chase -- doing mindless CURE day after day--
-- never any PREVENTION --
vibrations in engine room can cause a mechanical woodward governor of generator engines to malfunction -- after all it is flying centrifugal weights --
-- and a blackout--
all machinery in ER has its own NATURAL frequency.
they will RESONATE joyfully by raising or lowering their frequency at max amplitude.
a series of such vibrations will multiply several times its own pitch thus increasing HARMONICALLY all that are nearby--
thanks and best regards
