233-4 [Orig] Crankcase Fumes<br />
233-4.1 [<strong>A00064</strong>] An oil mist separator system utilizing centrifugal separation<br />
technology shall be provided with each engine to collect all oil mist and oil fumes<br />
generated and return it to the oil sump. The clean blow-by gases shall be<br />
dissipated through each engine’s air intake.<br />
233-5 [Orig] Engine Cooling System<br />
233-5.1 [Orig] Engine jacket water shall be cooled with raw water through an inboard heatexchanger<br />
system.<br />
233-5.1.1 [A00047] Raw water shall be strained through a duplex-type strainer fabricated<br />
from 70/30 copper nickel material with bronze valves. The strainers shall have<br />
the provision to clean one bowl, while operating the engine on the adjacent<br />
bowl. Strainer bowls shall be clear to allow for visual inspection. The basket<br />
shall be removable from the top of the strainer, without dismantling the strainer<br />
or disconnecting the piping. Access to the basket shall be via a quick access<br />
and all retaining mechanisms shall be captured to the strainer to prevent loss.<br />
233-5.1.2 [A00047] Each engine shall have separate sea suctions, and shall be fitted<br />
with bronze ball type seacocks.<br />
233-5.2 [Orig] Raw water systems shall have vents and drains so that the system can be<br />
completely drained, flushed and completely winterized without disassembling<br />
piping system joints.<br />
233-5.3 [Orig] Engine components, except charge air aftercoolers and fuel coolers, shall<br />
be cooled with jacket water. The jacket water shall meet the requirements on<br />
COMDTINST M9000.6E, Naval Engineering Manual, Chapter 233. Jacket water<br />
may be used as a heat source for cabin heating.<br />
233-6 [Orig] Emergency Shut Down<br />
233-6.1 [Orig] Each engine shall be provided with an emergency shut down control to<br />
activate an emergency shutoff for the fuel or air supply. The emergency shut down<br />
device shall be of the type which requires manual resetting before the engine can<br />
be restarted. It shall be operated remotely from the pilothouse. The actuator for<br />
the port engine shall be placed to the port side of the corresponding actuator for<br />
the starboard engine.<br />
233-7 [Orig] Jacket Water Heating System<br />
233-7.1 [Orig] Engine jacket water shall be heated to provide for rapid starting in colder<br />
climates. The jacket water heating system shall be powered by shore power only.<br />
The jacket water heating system shall be thermostatically controlled to heat the<br />
jacket water to a minimum temperature of 90 degrees Fahrenheit when the outside<br />
air temperature is at zero degrees Fahrenheit. The temperature shall be measured<br />
at the jacket water temperature gauge sending unit.<br />
233-8 [Orig] Lube Oil Sample Valve<br />
233-8.1 [Orig] Each engine shall have a lube oil sample valve installed as per<br />
COMDTINST M9000.6E, Naval Engineering Manual, Chapter 262.C.5.<br />
