摘要:
The invention relates to an arrangement for steering a water-craft (1), which comprises at least one main propulsion device (3, 3a, 3b, 11, 11a, 11b, 11c), which is arranged to push the water-craft (1) forward or backward, and a number of steering propulsion devices (2), the pushing direction of which can be changed. The steering propulsion devices (2) are arranged in the aft of the water craft (1) on both sides of the said at least one main propulsion device (3, 3a, 3b, 11, 11a, 11b, 11c) so that the steering of the water-craft (1) is continuously provided by means of the steering propulsion devices (2) without any separate rudder means of the like to be functionally connected to said at least one main propulsion device (3, 3a, 3b, 11, 11a, 11b, 11c).
摘要:
A method and arrangement for reducing the weight and optimizing the longitudinal strength of a water-craft (1), which is especially suitable for transportation of liquefied natural gas (LNG) or other corresponding mediums and comprises a hull (2), which has a deck (3) extending over at least the main part of the water-craft (1) and a number of substantially spherical cargo tanks (4) arranged successively in the longitudinal direction (A) of the water-craft (1) and a deckhouse (5), which extend substantially above the said deck (3). The hull (2) of the water-craft (1) is provided with a continuous protective casing structure (6) known as such and which is arranged on top of the cargo tanks (4). The said deck (3) of the water-craft is arranged on the hull (2) so that the proportion of its height measured from the bottom of the water-craft to the height of the uppermost continuous portion of the protective casing structure (6) on top of the cargo tanks (4) is at most 0,55, preferably at most 0,5. In addition said protective casing structure (6) is fixed to said deck (3) and/or other structures (7) supported to the hull (2) and is dimensioned together with the other parts of the hull (2) so that together they constitute an essential part of the overall strength of the water-craft.
摘要:
A method of arranging cabin decks in a large passenger vessel comprising a deck building (2) to be arranged at least for the most part above the board of the actual hull (1) of the vessel, which deck building includes a number of cabin decks (3) on top of each other which are provided with movable cabin units (4) preferably as prefabricated as possible, and in which in the lateral direction of the vessel, in the middle section thereof, each cabin deck (3) is provided with a longitudinal space, in which is arranged at least one cabin corridor (5) and a technical space (6), where at least most of the vessel's heating, plumbing, ventilation and electrical installation and/or corresponding systems for the cabin units on the cabin deck in question are installed. The cabin units (4) are arranged in said longitudinal space on both sides thereof side by side in the longitudinal direction of the vessel according to the pitch of the decks' transverse bulkheads (7) so that the lower parts of the walls of the cabin unit (4) being parallel with the transverse bulkheads are attached to the deck (3) in conjunction with said transverse bulkheads. The upper parts of the walls of the cabin unit (4) are arranged between said transverse bulkheads and are provided with a recess (4a) or a similar space for the flange part (7a) of the transverse bulkheads. Said systems in the technical space (6) are connected to the cabin units (4) between said transverse bulkheads (7) by piping, ducts or cables, which are at least substantially transverse with respect to the vessel.
摘要:
The present invention relates to a steering and propulsion arrangement in a large ship suited for transoceanic traffic, which arrangement comprises a number of propulsion devices situated partly at the rear and partly at the forebody of the ship. The forebody of the ship is provided with one or more steerable rudder propeller devices, which are arranged so as to substantially provide the steering and control of the ship, to produce a substantial part of the propulsive force pushing the ship forward at least substantially within all speed ranges, and in addition, arranged so that they do not extend, at least not significantly, below the base line of the ship.
摘要:
The invention relates to an arrangement and a method for collecting oil from water in open water and/or winter conditions, whereby a vessel's 1 hull 2 and an oil collecting equipment 4 are utilized as an oil collector. According to the invention, the oil collecting equipment 4 is attached to the vessel's 1 hull 2 and it is equipped with an auxiliary device 7, which comprises at least two auxiliary means 10a,b which are interconnected so that they are movable with respect to each other. The auxiliary means 10a,b can be utilized in various ways in different conditions.
