Bulkheads were known to the ancient Greeks, who employed bulkheads in triremes to support the back of rams. By the Athenian trireme era (500 BC), [1] the hull was strengthened by enclosing the bow behind the ram, forming a bulkhead compartment. Instead of using bulkheads to protect ships against rams, Greeks preferred to reinforce the hull with ...
The strength of ships is a topic of key interest to naval architects and shipbuilders. Ships which are built too strong are heavy, slow, and cost extra money to build and operate since they weigh more, whilst ships which are built too weakly suffer from minor hull damage and in some extreme cases catastrophic failure and sinking.
A material derived from alien Protomolecule, used as hull protective plating for ships. The Rocinante was one such ship upgraded to use the material, whilst other ships were constructed with it as an original part of the hull. The material itself contains no protomolecule, having been developed by simply observing the molecular structure. Cargonite
As modern ships are not made of timber, the same concept is known by several names; bulkhead, transversal frame or side girder. This steel framing is usually made with lightening holes. [1] [2] If floor timbers lay tight between the floor and the hull, bulkhead compartments are created.
A fire alarm control panel Fire alarm speaker and pull station. Fire alarm systems are composed of several distinct parts: Fire alarm control panel (FACP), or fire alarm control unit (FACU): This component, the hub of the system, monitors inputs and system integrity, controls outputs, and transmits information.
A girt is a vertically aligned girder placed to resist shear loads. Small steel girders are rolled into shape. Larger girders (1 m/3 feet deep or more) are made as plate girders, welded or bolted together from separate pieces of steel plate. [2] The Warren type girder replaces the solid web with an open latticework truss between the flanges ...

In shipbuilding, a strongback, known as a waler is oriented lengthwise along a ship to brace across several frames to keep the frames square and plumb. [1] In formwork strongbacks (typically vertical) reinforce typically horizontal walers to provide additional support against hydrostatic pressure during concrete pours.
