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 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.
Frequently, the main belt's armor plates were supplemented with a torpedo bulkhead spaced several meters behind the main belt, designed to maintain the ship's watertight integrity even if the main belt was penetrated. Furthermore, the outer spaces around the main belt in some designs were filled with storage tanks that could contain fuel oil ...
Full size interpretation of Noah's Ark in Dordrecht, Netherlands Noah's Ark at Tsing Ma Bridge in Hong Kong. The Bible gives the length of the ark as 300 cubits.Various cubits were in use in antiquity, [2] but to be considered "full-scale", an Ark replica would have to be somewhere in the range from about 135 to upward of 150 meters long (ca. 440 to 500+ feet).
Each tank is split into two or three independent compartments by fore-and-aft bulkheads. [1] The tanks are numbered with tank one being the forwardmost. Individual compartments are referred to by the tank number and the athwartships position, such as "one port", "three starboard", or "six center." [1]
A report from Marine Accident Investigation Branch (MAIB) has been published.
In multi-bulkhead systems, the innermost bulkhead is commonly referred to as the "holding bulkhead", [5] and often this bulkhead would be manufactured from high-tensile steel that could deform and absorb the pressure pulse from a torpedo hit without breaking. If the final bulkhead was at least 37 mm thick, it may also be referred to as an ...
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 ...
