Trawler sea chest (1 o 2)

Trawler sea chest

A sea chest is a recess in a ship’s hull that houses pipes to take in seawater. Water is pumped in for cooling engines, washing decks and as ballast to stabilise the vessel. A sea chest has a grille to keep out large items, but this can also stop smaller organisms from being flushed out.
