Reference Answer
### (a) Fore Peak Tank (4 Marks)
The fore peak tank is the forwardmost tank of a vessel, located forward of the collision bulkhead. Its primary functions are:
* **Ballast and Trim Control:** Its principal function is to carry seawater ballast. Filling or discharging this tank allows for precise adjustment of the ship's forward draft, thereby controlling the vessel's trim. This is critical for maintaining propeller immersion, ensuring adequate visibility from the bridge, and preventing bow slamming in heavy seas.
* **Collision Protection:** As per SOLAS regulations, the fore peak tank is positioned forward of the collision bulkhead. It acts as a sacrificial space or buffer zone in the event of a frontal collision. It is designed to absorb impact energy and be breached first, protecting the cargo holds and the integrity of the rest of the vessel from immediate flooding.
