Expansion Trunk
An expansion trunk is a compartment or a space on a ship that is designed to accommodate the expansion of fluids due to changes in temperature or pressure. It is usually located in the engine room or near the machinery spaces and is connected to the ship's piping system. The expansion trunk allows for the safe and efficient operation of the ship's machinery by preventing damage to the piping system and the machinery due to excessive pressure or temperature. The size and design of the expansion trunk depend on the type and size of the ship, as well as the type of fluid that needs to be accommodated.
