Where are the main drainage pumps located?

The main drainage pumps are typically located on the starboard side of a vessel. This placement is often based on the design and layout of the ship, which can influence the accessibility and efficiency of the pumps in carrying out their function effectively. Placing the pumps on one side, such as the starboard side, consolidates plumbing and reduces potential complications with water movement and drainage logistics.

In contrast, some vessels may have drainage systems on both sides to provide redundancy and ensure functionality in case one system fails. However, the question specifically pertains to the main drainage pumps, which in many designs are primarily positioned on the starboard side to streamline operations.

While pumps in the engine room may handle various other functions, it is the designation of the main drainage system that typically favors the starboard arrangement for reasons of ship design and operational efficiency.
