Today, bulk carriers make up 21 percent of the world's merchant fleets, [2] and they range in size from single-hold mini-bulk carriers to mammoth ore ships able to carry 400,000 metric tons of deadweight (DWT). A number of specialized designs exist: some can unload their own cargo, some depend on port facilities for unloading, and some even ...
A compartment is a portion of the space within a ship defined vertically between decks and horizontally between bulkheads.It is analogous to a room within a building, and may provide watertight subdivision of the ship's hull important in retaining buoyancy if the hull is damaged.
The underwater protection was an internal "bulge" that consists of four longitudinal torpedo bulkheads forming a multi-layered system designed to absorb the energy from an underwater explosion equivalent to 700 pounds of TNT (1.3 GJ). The protection system was designed for the torpedo bulkheads to deform and absorb energy while several ...
A bulkhead is a retaining wall, such as a bulkhead within a ship or a watershed retaining wall. It may also be used in mines to contain flooding.
