Butterworth Opening


Butterworth Opening is a type of sea chest, which is a chamber located in the hull of a ship that allows seawater to flow into the ship's systems for cooling or other purposes. The Butterworth Opening is a large rectangular opening in the hull of a ship that is used for cleaning and maintenance purposes. It is usually located near the waterline and is closed by a hinged door. The opening is named after the Butterworth company, which developed a cleaning system that uses high-pressure water jets to clean the inside of tanks and other enclosed spaces on ships. The Butterworth Opening allows access to these spaces for cleaning and maintenance.
