What is the purpose of bulkhead?
Vertical partition walls which subdivide the ship interior into watertight compartments. Bulkheads reduce the extent of seawater flooding in case of damage and provide additional stiffness to the hull girder. They can be flat or corrugated.
What is a bulkhead construction?

What are Class C bulkheads?
Class-C Panel: Class C bulkheads and decks are constructed of materials that are approved by SOLAS and classification societies as incombustible, but they are not required to meet any requirements related to rise in temperature or passage of smoke and flame to the unaffected side.
What makes corrugated bulkhead held more strength than the non corrugated bulkhead?
Damages due to Welding structural elements in double bottoms below bulkhead primary support members and stool plates.
How do bulkheads work?
A bulkhead fitting allows piping connections to be made to a tank. A hole is cut in the tank into which the fitting body is inserted. A locknut threads onto the body to hold it in place. The locknut puts pressure on the gasket(s) that allows it to make a liquid tight seal.
What are bulkheads made of?
Traditional bulkhead materials include wood timbers, treated lumber used for sheeting and steel sheet pilings. These materials work reasonably well and are cost-effective, but the wood can easily be damaged by the water and rot away, while the steel suffers from corrosion and electrochemical reactions.
What is wash bulkhead?

What are bulkheads in houses?
A bulkhead is a lower portion of the ceiling and is predominantly installed for functional reasons: to conceal services, to project air conditioning and to mask changes in ceiling heights. But kitchen bulkheads can also serve as decorative design features, as well as defining the kitchen area in an open-plan setting.
How are bulkheads built?
Bulkheads are normally constructed in the form of a vertical wall built in concrete, stone, steel or timber. The concrete, steel or timber walls can be piled and anchored walls, whereas the concrete and stone walls can also be constructed as gravity walls. Example of bulkhead structure constructed by Gabion mesh boxes.
Why are corrugated bulkheads used on ships?
Corrugated bulkhead is used as the bulkhead of cargo hold compartment of the some kinds of vessels for having easier maintenance, easier loading and unloading and more flexible shape in shrinkage and expansion by thermal load compared to the flat stiffened bulkhead.
