Abstract

A maritime vessel having a bow, a stern and a hull. Within the hull a cargo compartment being able to hold fluid and having a vertically extending column is provided. The cargo compartment contains a rotatable buoyant inner cargo tank extending around said column. The lower end of the vertically extending column is attached to the hull of said vessel.

Description

A marine vessel.
Field of the invention The invention relates to a maritime vessel having a bow, a stern, a hull and within the hull a cargo compartment being able to hold a fluid and having a vertically extending column, said cargo compartment containing a rotatable buoyant inner cargo tank extending around said column.
The laying of underwater cable is common practice today when every year, thousands of km cable is being submerged on our seabed. Cables of varying purpose are laid, for example fibre cable or power line. The cables are usually very long and require special dedicated vessels for transportation and cable-lay.
Traditionally, the fabricated cable may be delivered to a port where after it is spun up on a cable carousel positioned on the deck of a dedicated cable-lay vessel. This procedure can take several weeks but is normally necessary while a cable carousel loaded with cable can weigh as much as 1500000 kg being too heavy for most cranes.
The loading and unloading of cable is normally conducted while the cable carousel is rotating and the cable is either fed on or off the carousel. When unloaded into the ocean, the cable is fed from cable-carousel to a cable- lay mechanism and placed at the ocean seabed in a trench made by a trencher operating on the bottom. The
commercial technique used during cable-lay is to have a mechanical cable carousel placed on the deck of the cable-lay vessel.
Background of invention
Prior art The prior art describes various embodiments of cable-lay vessels comprising on deck stored mechanical cable- carousels where the cable carousels are in either
vertical or horizontal position. EP0919458 discloses such a cable-lay vessel comprising horizontally positioned mechanical cable carousels. The invention discloses a method of loading a cable carousel onboard a cable-lay vessel in the unconventional way of floating the cable carousel onboard.
EP2085308 discloses an apparatus with a floating tank for take up of cable, and a drive arrangement. The inner tank is designed as a floating body, with a floor and sides. The inner tank is placed inside an outer tank, so that an interstice is created between the inner tank and the outer tank for filling of fluid. A minimum of one support for the inner tank inside the outer tank permits rotation of the inner tank relative to the outer tank. The drive arrangement will turn the inner tank. There are several problems associated with the current prior art. Firstly, the problem with prior art cable carousels is the complexity of the system including the mechanical structure of the carousel and the rotating support structures situated underneath it. Further, the cable carousel occupies valuable space on deck and provides the vessel with a high centre of gravity.
EP2085308 is found not suitable for integration in a cable-lay vessel while it does not provide sufficient freedom in the shape of the outer cargo compartment and further include undesirable supportive structures to hold up and control the movements of the inner cable
container .
Summary of invention
It is an object of the present invention to solve the problems relating to prior art. This is achieved by that the lower end of a vertically extending column is attached to the hull of said vessel.
This construction enable load to be put on the vertically extending column while providing controlled vertical movement of the inner tank.
In one embodiment of the invention, the lower end of the vertically extending column is attached to the hull of said vessel. Thereby it is achieved, that the vertically extending column is able to hold a load while the inner cable container is able to move vertically. In one embodiment of the invention, the upper end of the vertically extending column is attached to the hull of said vessel. Thereby it is achieved, that the inner cable container has limited freedom of vertical movement and further achieved that said vertically extending column can withstand horizontal forces exerted by the inner cable container due e.g. to ocean swell.
In one embodiment of the invention, the inner cargo tank is pivotally fixated to the vertically extending column by means of friction reducing means such as a limited number of circumferential bearings extending along the periphery of the column. Thereby it is achieved, that the friction between the inner cable container and the cargo compartment is minimized while the inner cable container does not pivot substantially relative the vertically extending column.
In one embodiment of the invention, the inner cable container is pivotally fixated to the vertically
extending column by means of a limited number of
circumferential ball bearings extending along the
periphery of the column. Thereby it is achieved, that the friction between the inner cable container and the cargo compartment is minimized while the inner cable container does not pivot relative the vertically extending column.
In one embodiment of the invention, the inner cargo tank is pivotally fixated to the vertically extending column by means of a limited number of circumferential rolling bearing extending along the periphery of the column. Thereby it is achieved, that the friction between the inner cable container and the cargo compartment is minimized while the inner cable container does not pivot relative the vertically extending column.
In one embodiment of the invention, there is a pressure bearing between said inner cable container and the deck. The upward vertical movement of the inner cable container is arrested by means of said pressure bearing. It is thereby achieved, the upward buoyancy force exerted on the inner cable container will react against said
pressure bearing. It is thereby achieved, that relative the vessel, the inner cable container is not able to accumulate and release kinetic energy created by upward buoyancy forces. It is thereby achieved, smooth rotation of the inner cable container e.g. during rolling and pitching in sea-waves.
In one embodiment of the invention, there is a fluid regulating system. The fluid regulating system performs regulation of the amount of fluid contained in the interstice between the cargo compartment and the inner cable container. It is thereby achieved, a constant upward buoyancy force which react against said pressure bearing.
In one embodiment of the invention, there is a deck above the cargo compartment. Thereby it is achieved, that the vessel can carry equipment or cargo placed on the deck above said cargo compartment. In one embodiment of the invention, the cargo compartment comprises a fluid and that fluid is being a gel. Thereby it is achieved that the movement of the fluid due to e.g. sea swell is reduced for the benefit of stability of the maritime vessel and the function of the cable carousel.
In one embodiment of the invention, the cargo compartment comprises a fluid and that fluid has a specific density above 1000 kg/m3. Thereby it is achieved that the
movement of the fluid due to e.g. sea swell is reduced for the benefit of stability of the maritime vessel and the function of the cable carousel.
In one embodiment of the invention, the cargo compartment comprises a fluid and that fluid contains salt (NaCl) and that the specific density is above 1020 kg/m3. Thereby it is achieved that the movement of the fluid due to e.g. sea swell is reduced for the benefit of stability of the maritime vessel and the function of the cable carousel.

FIGURE 1 illustrates the cable-lay vessel with internal cable carousels.
FIGURE 2 illustrates a cross section of the cable
carousel . Detailed description of the embodiments
One embodiment of the invention is shown in figure 1, showing a maritime vessel (1) adapted for lying cable on the seabed. The vessel comprises bow (2), a stern (3), a deck (4) a hull (5) and a cable dispenser (6) . The hull (5) comprises internal structures of the vessel. On the deck (4) there is placed a trencher (7) which is used for creating a trench along the cable-lay route on the seabed. The cable (10) is being fed from the vessel (1) and positioned in the trench by the trencher (7) .
One embodiment of the invention is shown in figure 2, showing a cross section of the cable carousel (11) situated beneath the deck (4) . The cable carousel (11) comprises a cargo compartment (12) where said cargo compartment (12) could have a circular shape or have multiple corners. The cargo compartment (12) is
preferably cylindrical but the invention enables the choice of other shapes such as e.g. square, hexagonal or octagonal or any other suitable shape.
By the positioning of cargo compartments, it is achieved that space is saved on deck. Further, by the construction of the cable carousel (11) it is achieved that the above deck may hold significant loads.
The cable-lay vessel (1) has one inner cable container (13) fitted into each one of the cargo compartments (12) The inner cable container (13) is constructed to be watertight and able to float so that when the cargo compartment (12) is partially filled with fluid (20), said inner cable container becomes buoyant. Thereby it is achieved, that the inner cable container can be rotated without occurrence of substantial mechanical friction between the cargo compartment (12) and the inner cable container (13) . In one embodiment of the invention, the fluid held in the cargo compartment (12) has a viscosity being higher than water or brine, e.g. a gel. Thereby it is achieved that the movement of the fluid due to e.g. sea swell is reduced for the benefit of stability of the maritime vessel (1) and the function of the cable carousel (11) .
For the purpose of rotating the inner cable container (13) during loading and unloading of a cable package (19) the cable carousel (11) comprises at least one motor (12) with associated drive-arrangement comprising e.g. a gear (23) . The function of the described arrangement for the rotating of the inner cable container (13) is independent the shape of the cargo compartment (12) while the motor (12) may be positioned at those instances where the cargo compartment (12) is tangent the circular inner cable container (13) .
The cargo compartment (12) has a vertically extending column (14) which is stationary by attachment to the hull (5) at the upper and lower end of said column. The vertically extending column (14) may be attached to the hull (5) such that said column has its main shear force support at the upper attachment by means of a column support structure (17) at the upper attachment of said vertically extending column. When loaded with a cable package (19), the inner cable container (13) will obtain a substantial weight. The preventing of pivotal movement of the inner cable container due e.g. to ocean swell, may be controlled by the stationary vertically extending column (14) in the cargo compartment (12) . By the
described construction it is achieved that said column may withstand the significant horizontal forces applied by the inner cable container (13) . It is further achieved a lower centre of gravity of the cable-lay vessel (1) . The inner cable container (13) may be pivotally fixated to the vertically extending column (14) by means of a limited number of circumferential bearings (18) extending along the periphery of said column. The upward vertical movement of the inner cable container (13) is arrested by means of a pressure bearing (24) which is subjected to a constant upward force exerted by the inner cable container (12) . The inner cable container (13) is thereby not able to accumulate and release kinetic energy created by upward buoyancy forces exerted on the inner cable container (13) . This construction entails smooth rotation of the inner cable container (13) e.g. during rolling and pitching in sea-waves and makes the cable carousel (11) suitable for cable-lay
operations. In one embodiment of the invention, there is performed regulation of the amount of fluid contained in the interface between the cargo compartment (12) and the inner cable container (13) . It is thereby achieved, a constant upward buoyancy force which react against said pressure bearing (24) .
Due to the construction of the vertically extending column (14), said column is also part of the load bearing construction of the above ship deck (4) . The described construction is beneficial while marine vessels of this type are often equipped with heavy duty equipment or cargo placed on deck. When the cable package (19) is to be loaded to the cable- lay vessel (1), the cable is being distributed in the inner cable container (13) by means of cable distribution armature (21) while simultaneously rotating the inner cable container (13) . This procedure ensures that the cable is evenly distributed in a circular pattern
circumventing the vertically extending column (14).
When the cable-lay vessel (1) is in the starting position of the cable-lay route, a so-called trencher (7) may be submerged into the ocean, lake or like e.g. from said cable-lay vessel. The trencher (7) may create a trench along the cable-lay route and the cable is laid in the trench. The procedure of feeding the cable into the trench may be carried out by conducting the following operations simultaneously: unloading the cable from the inner cable container (13) while rotating said inner container in the direction reverse that of the loading direction; feeding the cable into the cable distribution armature (21); further feeding the cable into the ocean; further feeding the cable to the trencher (7); said trencher feeding the cable into the trench.
In one embodiment of the invention the marine vessel (1) is a container vessel which have been retrofitted and adapted for lying of cable inter alia by installing at least two cable carousels (11) underneath the deck of the container vessel.
