On deep-draft ships, what statement is true concerning high and low sea suctions for machinery space sea water cooling systems?
AI Explanation
The correct answer is A.
The reasoning is that on deep-draft ships, the high sea suction is located near the turn of the bilge and is used primarily in port or when operating in shallow water. This is because the high sea suction is located higher up on the ship's hull, allowing it to draw in cleaner, less turbid water when the ship is in shallower or confined waters. The low sea suction, located near the bottom of the ship, is used primarily while underway in deeper waters, where the water is less contaminated with sediment and debris.
The other options are incorrect because they do not accurately describe the locations and uses of the high and low sea suctions on deep-draft ships.
