Reference Answer
### 1. Purpose of a Low Sea Suction Sea Water Filter
The primary purpose of a sea chest and its internal filter (strainer) is to provide a reliable and clean source of seawater to the ship's various cooling systems while preventing the ingress of harmful debris. This is critical for protecting downstream machinery.
Key functions include:
* **Filtration:** To strain out marine life (fish, jellyfish, seaweed), sediment, and other debris that could clog or damage pumps, pipelines, heat exchangers, condensers, and other coolers.
