Where is the main drainage eductor located?

The main drainage eductor is primarily located on the starboard side lower level forward of the Forecastle Machinery Room (FMMR). This positioning is crucial for efficiently managing water drainage and ensuring proper functioning of onboard systems during operations. The eductor system utilizes the principles of venturi to create a vacuum that helps draw water away from compartments that may experience flooding or require drainage.

This location facilitates direct access to the bilge and other water accumulation points within the vicinity, effectively allowing for rapid response to any influx of water. The strategic placement at the lower level also ensures that gravity assists in the drainage process, maximizing the eductor's effectiveness. Having it positioned in the forward section allows for a quicker response to drainage needs in areas that are most likely to require it.

In contrast, the other locations provided do not serve this function as effectively, either due to their elevation or their proximity to areas that would not require such immediate drainage action.
