Ship with watertight wall

Abstract

The invention concerns a ship, said ship comprising a lower deck, such as a tank top, and an upper deck, such as a bulkhead deck, arranged above the lower deck, said lower and upper decks extending ina longitudinal direction of the ship, wherein the lower deck is provided with watertight walls (bulkheads) that extend vertically between the lower and the upper deck and define a plurality of separated watertight compartments distributed between the upper and lower decks, and wherein a first of said watertight walls extends in a transversal manner from side to side of the ship so as to separatetwo longitudinally adjacent first and second compartments. The invention is characterized in that the first watertight wall does not extend only in a transversal direction but also in the longitudinaldirection so as to provide the first compartment with a first longitudinally extending portion that extends into the second compartment, wherein the first longitudinally extending portion is arrangedat a first distance from a first side of the ship, and wherein the first distance is greater than a width or depth of a theoretical damage according to standard requirements for the type of ship concerned.

Description

technical field [0001] The invention relates to a vessel according to the preamble of claim 1 . [0002] In particular, the present invention relates to the structure of a bulkhead of a ship. Background technique [0003] The design of ships is governed by various safety regulations. Damaged vessels must meet specific criteria related to heel / inclination, freeboard height, etc. This is mainly solved by designing the ship with inner watertight bulkheads at a certain distance. The distance between these bulkheads is determined by the requirements of the Convention for the Safety of Life at Sea (SOLAS) issued by the International Maritime Organization (IMO). In this example, the above distance is determined by SOLAS 90, regulation II-1 / B / 8. In addition, for RO-RO (roll-on / roll-off) passenger ships operating in European waters, they also need to meet the special damage requirements stipulated in the "EU Directive 2003 / 25 / EC". These requirements stipulate that the bulkhead d...

Problems solved by technology

[0019] In some cases, however, the size of the engine (which is related to the size of the ship) makes it difficult to meet the above-mentioned regulations for separate compartments if the compartments are arranged in a conventional manner, because even one of the separate compartments The total volume is too large

[0020] In the case of ro-ro ships, there is often another difficulty, as the position of the cargo hold necessitates placing the engines further aft than in other types of ships
