Reference Answer
### (i) Protection Against Flooding in a Periodically Unattended Machinery Space (UMS)
As per SOLAS Chapter II-1 and Classification Society rules for UMS notation, the primary objective is to ensure that any flooding can be detected and controlled automatically, and that an alarm is raised to summon engineering staff before a dangerous situation develops. The requirements are comprehensive:
**1. Bilge Water Detection and Pumping:**
* **Bilge Well Design:** As cited in the reference, bilge wells must be located strategically to ensure that liquid accumulation is detected at normal operational angles of heel and trim. They must be of sufficient capacity to contain normal drainage during the unattended period without activating alarms.
