🔍 Key Concepts

• Purpose of high sea suction vs low sea suction in a seawater cooling system • How ship draft, trim, and sea state affect which sea chest you use • Risk of air ingestion, loss of suction, or clogging in different operating conditions

💭 Think About

• Think about when the seawater inlet might be too close to the water surface, and what could happen to the pump in heavy seas. • Consider when the seawater inlet might be too close to the bottom and more likely to ingest mud, silt, or debris. • Ask yourself which operating condition makes it more important to have the suction deeper in the water versus higher off the bottom.

✅ Before You Answer

• Identify in which situations the vessel is most likely to experience rolling, pitching, or the sea surface dropping away from the hull near the sea chest. • Identify in which situations the vessel is closest to the bottom or in silty/shallow water where sand and mud are a problem. • Match each answer choice to either: avoiding air/surf ingestion at the surface or avoiding mud/debris ingestion from the bottom.
