Embodiment Construction

[0025] In the figures, reference numeral 1 refers to the hull of a vessel or floating structure provided with a bow or similar hull part 2 and with a bottom 3 or similar underwater part. Specific reference such as Figure 1-4 In the embodiment shown, the prow-like end 2 is located below the waterline of the hull with the protruding part 4, which may be provided with one or several flow channels 6 containing pumping means or propellers 8 for A strong current directed primarily upwards is generated and used to direct the current towards the ice field encountered by the prow-like end, as shown in the other drawings.

[0026] Figure 1-4 Only one flow channel 6 is shown, which is divided into two branches 6a and 6b. But if necessary, in other words, depending on the structure of the ship, its purpose and area of ​​operation and thus the nature of the possible ice loads in practice, multiple channels can preferably be provided in the area of ​​the bow end , the ice mainly impact...

Abstract

The invention relates to a vessel or a floating structure operating in ice-covered waters comprising a hull or the like (1, 1 ') including at least one bow-like end or a similar hull portion (2, 2'), which is exposed to the loading effect of the ice, while the ice or the vessel is moving. Said bow-like end or a similar hull portion (2, 2'), in the underwater part of the hull, is equipped with means for leading one or several strong, mainly upwards-directed flows of water towards the ice or the ice field encountered by the bow-like end or a similar hull portion (2, 2'). The invention also relates to a method of using the vessel or the floating structure.

Description

technical field [0001] The invention relates to a vessel or floating structure operating in ice-covered water according to the preamble of claim 1, the vessel or installation comprising a hull or similar structure containing At least one bowtip or similar hull section subjected to the loading effects of ice. The invention also relates to a method of using a vessel or floating structure according to the preamble of claim 12 . Background technique [0002] Oil exploration and drilling activities in ice-covered sea areas are carried out by using different kinds of ships and floating structures such as oil drilling platforms. Especially in so-called drill ships, the hull of the ship is provided with a drilling derrick and a drilling device. In order to maintain the ship's position, it needs to be anchored. For this purpose different kinds of anchor cable systems are used which extend through the bottom of the ship to the sea bottom. In addition, in order to maintain the posi...
