The specific embodiment
Referring to Fig. 1 to Fig. 6, the present invention is a kind of semi-submersible offshore multifunctional engineering ship, and it comprises hull and the hoisting crane of installing on hull.
Hull is a U-shaped semi-submersible hull structure, is different from the hull of common engineering ship.The U-shaped opening size of U-shaped hull is to determine after having taken all factors into consideration the yardstick of dissimilar marine drilling platforms.The above water of U-shaped hull is a upper box 1, and the lower apron of U-shaped hull is equipped with the heavy pad 2 of fleetline under water.This heavy under water pad 2 is made up of the heavy pad 21 of larboards of vertical setting and the heavy pad 22 of starboard and laterally heavy pad 23, and the heavy pad 21 of larboard and the heavy pad 22 of starboard fill up 23 and are connected by laterally heavy.Several columns 3 of installing between upper box 1 and heavy under water pad 2.As shown in fig. 1, three columns 3 are placed in U-shaped hull one side, at three columns 3 of the same arrangement of U-shaped hull opposite side, like this, have settled six columns 3 under water between the upper box 1 of U-shaped hull and heavy pad 2.Certainly, the column of being installed 3 can be more than six.
Hoisting crane is the large-scale full circle swinging hoisting crane 4 of two platform independent work, is installed on upper box 1 deck of U-shaped hull, and is positioned at the top of stem 16 place's columns 3.Left side hoisting crane 41 is placed in upper deck stem 16 left-hand portion of U-shaped hull, and right side hoisting crane 42 is placed in the position, upper deck stem 16 right side of U-shaped hull.
Bow propelling unit 8 is installed at stem 16 positions at the U-shaped hull, in the ship stern position of U-shaped hull stern propelling unit 9 is installed.Ship stern position in upper deck is provided with helicopter landing platform 5, and as shown in Fig. 1 and Fig. 3, helicopter landing platform 5 is positioned at ship stern one side of U-shaped hull.In conjunction with referring to Fig. 4, propelling unit is arranged in the vertically heavy under water pad, and propelling unit comprises larboard bow propelling unit 81, starboard bow propelling unit 82, larboard stern propelling unit 91 and starboard stern propelling unit 92.Arrange that different propelling units can satisfy different dynamic positioning requirements.
This auxiliary vessel is except carrying out marine hoisting operation, can lay draw-beam 11 at the U-shaped opening part of U-shaped hull and be used for the load-bearing deck, also can be used as the support beam of the above water platform of lifting platform, perhaps the draw-beam of the jacket under water of conduct lifting platform.Draw-beam 11 can be set to several draw-beams, utilizes draw-beam to carry out the installation or the dismounting of offshore platform.Draw-beam and attached lifting means thereof can be installed or remove with two full circle swinging hoisting cranes on the ship.Crane arm support 6 on even keels are shelved on the ship stern crane arm shelf 7 of a side, do not influence the normal operation of draw-beam 11 this moment.
This auxiliary vessel is equipped with the laying work line with the modular form design and installation, and the laying work line is installed in the U-shaped hull groove on the module on the main deck, and the pipe laying module is installed by 4 liftings of two full circle swinging hoisting cranes.As shown in Fig. 5 and Fig. 6, the laying work line along U-shaped hull line of centers according to from the ship stern work flow towards the stem direction arrange.Under the pipe laying pattern, increased the needed stinger 12 of laying work at the bow of ship, a part of equipment of laying work line is installed on the horizontal casing, according to the different requirements of pipe-laying equipment, allows the pipe laying module to protrude in the certain-length of hull.
Again in conjunction with referring to Fig. 6, under the pipe laying pattern, increased pipe laying module 15 at the U-shaped opening part of U-shaped hull, the required equipment of pipe laying has been installed on pipe laying module 15.Two side decks of U-shaped opening can be used for storing the pipe that ships from barge for heap area under control 17.The door frame hoisting crane 14 that the jib hoisting crane 13 that is used for lifting pipes and stockyard are used also is housed on its two sides deck.
According to engine request, can the pipe laying module be installed on this auxiliary vessel, carry out laying work, also the pipe laying module can be removed, carry out other marine engineering operation.
Semi-submersible offshore multifunctional engineering ship of the present invention is when carrying out the hoisting operation pattern, and the minimum attendant equipment of configuration utilizes the ballasting system of ship itself just can carry out normal hoisting operation on the ship, and ship two sides are provided with certain between deck space can satisfy job requirements; Draw-beam can also be placed in the U-shaped opening part of U-shaped hull, be used to increase floor space.
Semi-submersible offshore multifunctional engineering ship of the present invention is when carrying out the pipe laying pattern, at first utilize two hoisting cranes of self that the stinger 12 of stem and the pipe laying module 15 of U-shaped opening part are installed, required weight-lifting equipment and the stockyard equipment of pipe laying is installed on the deck of U-shaped opening two sides then, as jib hoisting crane 13 and door frame hoisting crane 14, it is carried out just can using after the secure fixation.
Semi-submersible offshore multifunctional engineering ship of the present invention is when carrying out the above water platform of dismounting platform, utilize the U-shaped opening hull to be positioned at the both sides of platform position, the ballasting system adjustment makes the position that hull sinks to be needed, utilize hoisting crane and accessory equipment that the draw-beam of needs is punctured into the platform below again, the ballasting system draining makes the hull come-up, and upper mounting plate is hung jacket.
Semi-submersible offshore multifunctional engineering ship of the present invention is when carrying out the jacket under water of dismounting platform, utilize the U-shaped opening hull to be positioned at the both sides of platform position equally, the ballasting system adjustment makes the position that hull sinks to be needed, utilize the jacket under water of the weight-lifting equipment lifting platform of draw-beam top again, the ballasting system draining can be moved simultaneously with lifting appliance, and the jacket under water of platform is pulled away from the seabed pedestal.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the present invention, and be not as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claim of the present invention conversion, the modification of the foregoing description.
