Reference Answer
### (a) Fore Peak Tank
**Location**: The Fore Peak Tank is situated in the extreme forward part of the vessel, forward of the collision bulkhead. This bulkhead is a statutory requirement, designed to be watertight and located at a specified distance from the forward perpendicular, typically not less than 5% of the ship's length (Lpp) and not more than 8% of Lpp.
**Main Functions**:
* **Collision Protection**: Its primary safety function is to act as a sacrificial space in the event of a bow collision. By absorbing impact energy and containing water ingress to this compartment, it protects the adjacent cargo holds, engine room, and accommodation spaces from flooding, thereby significantly enhancing the vessel's survivability and mitigating environmental pollution.
