Sea chest location

Hi,
I have a question regarding to sea chest in the engine room.
Could we place the sea chest between two engine rooms? In other words on the BHD that separate the engine room.
Any rules or regulations to confirm or reject this type of concept.
Thank you for your attention.

 

I wouldn't do it for the simple reason that blocking the sea chest knocks out both engines.
Are we talking centerline bulkhead or transverse bulkhead? What damage requirements?

 

DNVGL Part 4 Chapter 6 Section 5
2.3 Sea inlets for cooling water pumps
2.3.1 Sea-water cooling systems for the main and auxiliary machinery shall be connected to at least two cooling water inlets, preferably on opposite sides of the ship. Guidance note: The inlets may be arranged as high and low suctions. ---e-n-d---o-f---g-u-i-d-a-n-c-e---n-o-t-e---
2.3.2 Strums shall be fitted to all sea chest openings in the shell plating. The total area of the strum holes shall be at least twice the total flow area in the sea water inlet valves.
2.3.3 Where sea water is used for cooling the main engines or auxiliary engines, the cooling water, suction lines shall be provided with strainers which can be cleaned without interrupting the cooling water supply.

 

Also important, likely more, are flow issues on the hull there.

Another expert is @baeckmo. I suspect he may want to see a side view of the hull with the bh/location distances..

outta my league, but you might want to consider things like proximity to props, underwater hull forms, etc over convenient location

Thank you. I do agree to your reason. This a transverse bulkhead and almost in the midship area.

 

Thank you. This sea chest is located almost in the midship area closed to centerline in flat bottom area.
