Problems solved by technology

[0004] The disadvantage is that the sea box formed outside the hull of the vessel creates additional volume, sailing resistance, weight and thus additional draft and fuel consumption
In addition, the sea boxes take up space that could be effectively used, for example, to transport cargo
Furthermore, water inlets or channels formed in the side walls of the vessel constitute a mechanical weakening which increases the risk, which is disadvantageous, for example in the case of a transverse collision

Embodiment Construction

[0024] figure 1 Shell plating 1 and 2 are shown at a distance, forming a double bottom 3 of the whole (shown partially) of a vessel 4 (shown schematically). The vessel 4 is provided with one or more heat exchangers 5 arranged between the shell plating 1 and the shell plating 2 in the double bottom 3 however present.

[0025] Control members 6 (which can be closed or adjusted in the diameter or width of their passages) are usually provided in the forward hull plating or on the side of the double hull plating 1, 2, said control members acting as channels for cooling water (in particular is the inlet and channel member 6 of seawater). Furthermore, ducts (not shown in the figures) may form part of the channel member 6 which, like the channel member of the control member 6, extends to the heat exchanger 5 and from there to a channel not formed in the side hull of the vessel. One or more outlets 7 for discharge into the sea. The various control means 6 can be controlled, for exam...

Abstract

There is disclosed a vessel having a double bottom, in which double bottom cooling water passage means are provided and in which heat exchangers coupled to said cooling water passage means are disposed. In particular, the heat exchangers are disposed in channels extending in the longitudinal direction in the double-walled bottom of the vessel. Selective closure of certain channels makes it possible to carry out maintenance and repairs, at sea, on the heat exchanger(s) present therein during normal operation of the vessel based on a forced flow.

Description

technical field [0001] The invention relates to a ship with a double bottom in which one or more heat exchangers are arranged. [0002] The invention further relates to a heat exchanger, in particular a cooler, suitable for use in the aforementioned vessel; and to a cooling water system comprising such a heat exchanger. Background technique [0003] Such heat exchangers and ships equipped with such heat exchangers are generally known. It is especially known to provide said ships with special so-called "sea boxes" in which heat exchangers are arranged. The sea box is usually provided on one or more sides, for example on the front side of the bulge or for example on the side of the ship. Furthermore, such ships with double-walled hulls are known in which hull passages are provided for ballast water for filling the double bottom as required with overboard water acting as Ballast in order to obtain the desired draft and / or stability of the ship without cargo. [0004] The di...
