What provision is made for sea chests for removal of air ingested into the sea chest of a machinery space sea water cooling system?
AI Explanation
The correct answer is B) The air may be continuously removed by an open valve located in the vent line originating from the top of the sea chest and terminating above the deep-draft load line.
This is the correct answer because the regulations require that any air ingested into the sea chest of a machinery space sea water cooling system must be continuously removed through a vent line that terminates above the deep-draft load line. This ensures that any air is vented overboard and does not accumulate within the sea chest, which could disrupt the cooling system. The other options are incorrect because they either vent the air to the bilges, which is not permitted, or use a drain line instead of a dedicated vent line, which is also not in compliance with the regulations.
