Description
Technical Field
The invention relates to the field of ship design and ship construction, in particular to a catenary suspension type single-point buoy capable of resisting and breaking ice.
Background
Along with the development of marine petroleum resources, CALM catenary single-point equipment is widely applied, but in an ice region, the following problems exist in the application of catenary single-point buoys:
⑴ the ice accumulates on the buoy and pushes the buoy to deflect, so that the tension of the mooring cable increases and the risk of breaking exists.
⑵ the continual buildup of sea ice creates a greater pressure around the buoy, causing the bowl to collapse.
⑶ continued ice build-up on the sea can cause damage to the risers below the buoy.
Therefore, the ice-resistant catenary single-point buoy needs to be invented, which can effectively resist ice and does not influence the normal operation of catenary single points.
Disclosure of Invention
In order to solve the problems, the invention provides an anti-ice catenary suspension type single-point buoy, which aims to achieve the purposes of saving cost and having strong ice breaking capacity, and adopts the technical scheme that:
an ice-resistant catenary type single-point buoy is provided with a cylindrical buoy, an oil pipeline is arranged in the buoy, a buoy body is connected with a chain stopper, an ice breaking piece is fixed in the middle of the buoy body and is annular, the ice breaking piece is fixedly connected with the outer cylinder wall of the buoy, and the center of the outer ring wall of the ice breaking piece is in a tip shape; the lower end of the oil conveying pipe is connected with a vertical pipe, an oil conveying pipe protection cover is sleeved outside the vertical pipe, and the oil conveying pipe protection cover is horn-shaped; the chain stopper top cover is equipped with the arc safety cover, safety cover one end is provided with the bracing piece, the safety cover with be provided with the reinforcing plate between the piece that opens ice.
The ice breaking piece is fixed on the middle part of the floating barrel and the wall of the outer barrel in a surrounding mode, the front end of the ice breaking piece is in a tip shape, the floating barrel floats up and down on the sea surface to drive the ice breaking piece to move up and down, and the tip of the ice breaking piece can break the ice surface, namely ice is broken. Defeated oil pipe safety cover protects defeated oil pipe, blocks the sea ice outside defeated oil pipe safety cover, protects the stand pipe, prevents to freeze around the riser. End chain ware top cover and protect chain ware, the arc safety cover protection that establishes ends chain ware top is established in chain ware top, will end chain ware environmental protection, because arc safety cover top is the arc, sea ice falls into or fills in the space between arc safety cover and the piece that opens ice, can be along the shell landing of arc safety cover, prevents that the garrulous ice from producing stress concentration at the hookup location and causing structural damage, and then plays the effect of protection chain ware.
Preferably, the outer annular wall of the ice breaking element gradually gathers from two sides of the annular wall to the center to form a tip. The tip facilitates ice breaking.
Above-mentioned anti ice type catenary type single-point flotation pontoon, preferably, the bracing piece is "T" type, sets up in reinforcing plate below. The supporting rod and the reinforcing plate both play a role in reinforcing and supporting the icebreaking piece.
Above-mentioned anti ice type catenary type single-point flotation pontoon, preferably, the inner ring wall of the piece that opens ice with the outer cylinder wall of flotation pontoon is laminated. The ice breaking piece is tightly attached to the buoy and fixedly connected, so that ice breaking is more powerful.
The ice-resistant type catenary single-point buoy with the structure has the advantages that the annular ice breaking piece is additionally arranged outside the buoy, so that the ice breaking function is achieved, the structure is simple, the key parts of the catenary single-point buoy and the ice-resistant protective cover at the position avoid damage of sea ice to the structure, the cost is low, the ice breaking capacity is high, and the catenary single-point buoy has the capacity of serving ice areas.
Drawings
FIG. 1 is a schematic structural view of the present invention;
wherein: 1-buoy, 2-icebreaking piece, 3-oil pipeline, 4-riser, 5-reinforcing plate, 6-support rod, 7-oil pipeline protective cover, 8-arc protective cover and 9-chain stopper.
Detailed Description
The invention is further explained by combining the attached drawings, and the ice-resistant catenary suspension type single-point buoy shown in figure 1 is provided with a buoy 1, an ice breaking piece 2 is arranged at the middle part of the buoy and the wall of an outer cylinder in a surrounding manner, the ice breaking piece is annular and is fixedly connected with the buoy, and the outer side of the ice breaking piece is in a tip shape. An oil delivery pipe 3 is arranged in the buoy, the lower end of the oil delivery pipe is connected with a vertical pipe 4, the vertical pipe extends out of the buoy, an oil delivery pipe protective cover 7 is sleeved outside the vertical pipe, and the oil delivery pipe protective cover expands outwards to be horn-shaped. The arc-shaped protective cover 8 is arranged above the chain stopper 9 in a covering mode, the supporting rod 6 is arranged at one end, close to the floating barrel, of the arc-shaped protective cover, the reinforcing plate 5 is arranged between the arc-shaped protective cover and the ice breaking piece, and the ice breaking piece is well reinforced and fixed.
The ice-resistant type catenary single-point buoy with the structure has the advantages that the annular ice breaking piece is additionally arranged outside the buoy, so that the ice breaking function is achieved, the structure is simple, the key parts of the catenary single-point buoy and the ice-resistant protective cover at the position avoid damage of sea ice to the structure, the cost is low, the ice breaking capacity is high, and the catenary single-point buoy has the capacity of serving ice areas.
