  2. Deck (ship) - Wikipedia

    en.wikipedia.org/wiki/Deck_(ship)

    A deck is a permanent covering over a compartment or a hull [1] of a ship. On a boat or ship, the primary or upper deck is the horizontal structure that forms the "roof" of the hull, strengthening it and serving as the primary working surface. Vessels often have more than one level both within the hull and in the superstructure above the ...

  3. Bulkhead (partition) - Wikipedia

    en.wikipedia.org/wiki/Bulkhead_(partition)

    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 extra timber along the waterline, making larger ships almost resistant to ramming by smaller ones. [2]

  4. Hull (watercraft) - Wikipedia

    en.wikipedia.org/wiki/Hull_(watercraft)

    Hull form lines, lengthwise and in cross-section. A hull is the watertight body of a ship, boat, submarine, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast.

  5. Mid-deck tanker - Wikipedia

    en.wikipedia.org/wiki/Mid-Deck_Tanker

    The extra deck is placed at about the middle of the draft of the ship. This design is an alternative to the double-hull tanker design, and is superior in terms of spill volume. Although double-hull design is superior in low energy casualties and prevents spillage in small casualties, in high energy casualties where both hulls are breached, oil ...

  6. Architecture of the oil tanker - Wikipedia

    en.wikipedia.org/wiki/Architecture_of_the_oil_tanker

    A Mid-Deck Tanker is a tanker design, which includes an additional deck intended to limit spills if the tanker is damaged. The extra deck is placed at about the middle of the draft of the ship. [citation needed] With double hull tankers, in high energy casualties where both hulls are breached, oil can spill through the double-hull and into the sea.

  7. Compartment (ship) - Wikipedia

    en.wikipedia.org/wiki/Compartment_(ship)

    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 ram attacks, Greeks preferred to reinforce the hull with extra timber along the waterline, making larger ships almost resistant to ramming by smaller ones.

  8. Double hull - Wikipedia

    en.wikipedia.org/wiki/Double_hull

    Single hull, Double bottom, and Double hull ship cross sections. Green lines are watertight; black structure is not watertight. A double hull is a ship hull design and construction method where the bottom and sides of the ship have two complete layers of watertight hull surface: one outer layer forming the normal hull of the ship, and a second inner hull which is some distance inboard ...

  9. Naval architecture - Wikipedia

    en.wikipedia.org/wiki/Naval_architecture

    The complete structure of the ship is designed with panels shaped in a rectangular form consisting of steel plating supported on four edges. Combined in a large surface area the Grillages create the hull of the ship, deck, and bulkheads while still providing mutual support of the frames. Though the structure of the ship is sturdy enough to hold ...
