Bulkhead
Bulkhead turns up in 2 fields: maritime, mechanical. Here is what it means to the people in each one.
Bulkhead in maritime
A vertical partition that divides the interior of a ship into separate compartments.
An upright wall within the hull of a ship that separates different structural areas or rooms. Watertight bulkheads are heavily engineered to prevent flooding from spreading if the hull is breached. In everyday naval and marine slang, the term is used for any interior wall, regardless of its structural importance.
"Secure that gear against the aft bulkhead before we hit rough water."
Bulkhead in mechanical
A rigid partition used to separate compartments or mount feed-through connectors.
A structural wall or panel that separates distinct zones within a machine or vehicle, often isolating pressure, fluids, or heat. In fluid power and wiring, it refers to the specialized fittings designed to pass through these panels while maintaining a tight seal. Engineers rely on them to route lines safely across physical barriers without compromising structural integrity.
"We need a sealed bulkhead fitting for the hydraulic lines passing through the firewall."
