A bulkhead is an upright wall within the hull of a ship. A hull is the body of a Ship or Boat. It is a central concept in floating vessels as it provides the Buoyancy that keeps the vessel from sinking A ship /ʃɪp/ is a large vessel that floats on water Ships are generally distinguished from Boats based on size Other kinds of partition elements within a ship are decks and deckheads. A deck is a permanent covering over a compartment or a hull of a Ship. A deckhead is the underside of a deck in a Ship. It bears the same relationship to a compartment on the deck below as does the ceiling to the room of a House

Etymology

The word bulki meant "cargo" in Old Norse. Old Norse is the North Germanic language that was spoken by inhabitants of Scandinavia and inhabitants of their overseas settlements during the Viking Age The Song Dynasty Chinese author Zhu Yu wrote of Chinese ships with watertight bulkhead compartments in his book Pingzhou Table Talks of 1119 AD. The Song Dynasty ( Wade-Giles: Sung Ch'ao was a ruling dynasty in China between 960&ndash1279 CE it succeeded the Five Dynasties and Ten Kingdoms The term Chinese people may refer to any of the following A person who resides in and holds citizenship of the People's Republic of China (including Hong Zhu Yu ( was an author of the Chinese Song Dynasty (960-1279 AD A Chinese trade ship dated to 1277 AD was found off the southern coast of China in 1973, and had 12 bulkhead compartment rooms in its hull. Year 1973 ( MCMLXXIII) was a Common year starting on Monday (link will display full calendar of the 1973 Gregorian calendar.

Sometime in the 15th century sailors and builders in Europe realized that walls within a vessel would prevent cargo from shifting during passage. In shipbuilding, any vertical panel was called a "head". So walls installed abeam (side-to-side) in a vessel's hull were called "bulkheads. "

Now, the term bulkhead applies to every vertical panel aboard a ship, except for the hull itself.

Purpose

Bulkheads in a ship serve several purposes:

Some bulkheads and decks are fire-resistance rated to achieve compartmentalisation, a passive fire protection measure. A deck is a permanent covering over a compartment or a hull of a Ship. A fire-resistance rating typically means the duration for which a Passive fire protection System can withstand a standard fire resistance test. Passive fire protection (PFP is an integral component of the three components of structural Fire protection and fire safety in a Building.

Requirements of bulkheads

Fire-resistance

Openings in fire-resistance rated bulkheads and decks must be firestopped to restore the fire-resistance ratings that would otherwise be compromised, if the openings were left unsealed. A firestop is a Passive fire protection System of various components used to seal openings and joints in fire-resistance rated wall The Authority Having Jurisdiction for such measures varies depending upon the flag of the ship. In the fields of Architecture and Civil engineering, construction is a process that consists of the Building or assembling of Infrastructure Merchant vessels are typically subject to the regulations and inspections of the Coast Guards of the flag country. Combat ships are subject to the regulations set out by the navy of the country that owns the ship.

Prevention of damage from EMI and EMP

Bulkheads and decks of warships may be fully grounded (electrically) as a countermeasure against damage from EMI and EMP due to nuclear or electromagnetic bomb detonations near the ship, which could severely damage the vital electronic systems on a ship. A countermeasure is a system (usually for a Military application designed to prevent Sensor -based Weapons from acquiring and/or destroying a target An electromagnetic bomb or E-bomb is a weapon designed to disable electronics with an Electromagnetic pulse (EMP that can couple with electrical/electronic systems System (from Latin systēma, in turn from Greek systēma is a set of interacting or interdependent Entities, real or abstract

In the case of firestops, cable jacketing is usually removed within the seal and firestop rubber modules are internally fitted with copper shields, which contact the cables' armour in order to ground the seal. There are also conductive fill materials in use for that purpose, which must be in direct contact with cable armour to ensure full grounding of the bulkheads and decks.

Other uses of the term

The term was later applied to other vehicles, such as railroad cars, hopper cars trams, automobiles, aircraft or spacecraft, as well as to containers, intermediate bulk containers and fuel tanks. A railroad car or railway carriage is a Vehicle on a rail transport system (railroad or railway that is used for the carrying of Cargo or A hopper car is a type of Railroad freight car used to transport loose bulk commodities such as Coal, Ore, grain, Track ballast A tram, tramcar, trolley, trolley car, or streetcar is a railborne vehicle, of lighter weight and construction than a Train A spacecraft is a Vehicle or machine designed for Spaceflight. Containerization (or containerisation) is a system of Intermodal freight transport Cargo Transport using standard ISO containers An Intermediate bulk container ( IBC) is a container used for transport and storage of fluids and bulk materials A fuel tank is safe container for flammable liquids and typically part of an Engine system in which the Fuel is stored and propelled (fuel pump or released (pressurized In some of these cases bulkheads are airtight to prevent air leakage or the spread of a fire. The term may also be used for the "end walls" of bulkhead flatcars. A flatcar (also flat car) is a piece of Railroad rolling stock that consists of an open flat deck on four or six wheels or a pair of trucks (US or

Mechanically, a partition or panel through which connectors pass, or a connector designed to pass through a partition.
