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.
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 ...
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.

In the Coulombi egg design spillage is greatly reduced, possibly to zero. Where a double hull VLCC has a ballast tank coated area of about 225,000 m³, in a Coulombi egg tanker this area is reduced to 66,000 m³. This reduces maintenance and corrosion risks, which otherwise may result in structural failure, as was the case with the Erika and ...
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.

A bigger problem was that detailed design work for the ships was falling behind as the design team struggled to come up with a solution that ticked all the boxes and satisfied the customer, CMAL.
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.
The 746-foot-long, double-hull ships can carry 162,000 barrels of fuel, 6,675 tons of dry cargo, and 1,716 tons of refrigerated stores. A helicopter deck at the stern also enables VERTREP.
