12, then seal cover board 9, rubber pad ring 12 are fixed on fairlead flanged plate 4 with fastener (bolt, nut and washer),
Utilize former mating rubber pad ring 12, it is ensured that seal cover board 9 is sealed with fairlead flange.
Rubber bellows 11:To meet mooring cable when Ship dynamic situation, tide and stormy waves change, at the fairlead on
Under, left and right, swing working condition requirement, select internal diameter to match rubber bellows 11 with guiding steel pipe 10 on seal cover board 9, rubber
11 upper end of glue telescoping tube is Nian Jie with guiding steel pipe 10 on seal cover board 9 with sealing mightiness belt 5, and lower end and mooring cable 1 are with close
Envelope mightiness belt 5 is fastened.
Rubber washer 6:Using rubber packing, to ensure that 11 lower end inside of rubber bellows is sealed at mooring cable 1,
Centre reaches airtight using rubber washer 6, first with fluid sealant that rubber washer 6 is be bonded with mooring cable 1, then strongly with sealing
Rubber bellows 11 and rubber washer 6, mooring cable 1 are alternateed at least three layers of winding by adhesive tape 5.Under rubber bellows 11
At end and mooring cable 1 sealing is again ensured that with sealing glue sticking again.
Seal mightiness belt 5:Using the cloth base adhesive tape of 3M, sealing mightiness belt 5 be for 11 upper end of rubber bellows with it is close
Guiding steel pipe 10 bonding, 11 lower end of rubber bellows and mooring cable 1 are fastened used on capping plate 9, airtight to ensure, close
Seal alternately at least three layers of the winding of mightiness belt 5.
11 upper end of rubber bellows is Nian Jie with seal cover board 9 with sealing mightiness belt 5, lower end and the sealing of mooring cable 1
Mightiness belt 5 is fastened.
Fluid sealant:Using strength AB fluid sealants, for adhesive rubber washer 6 and 11 times mooring cable 1, rubber bellows ends
End is sealed at mooring cable 1.
The research method taken:
It is first whole to consider how sealing and quick and easy for installation using method local after first entirety, utilize inventory's plank
Steel pipe and former institute supplementary material, reduce cost, effectively control quality, are then sealed the selection of cover board 9, rubber bellows again
11 select, and rubber washer 6 is selected, and sealing mightiness belt 5 is selected, and fluid sealant is selected.
The embodiment advantage:It is (including former at fastener and fairlead using inventory's plank, steel pipe and former institute's supplementary material
The mating rubber pad ring of institute), selection is convenient, using guiding 9 good seal performance of steel pipe sealing cover board.
The embodiment disadvantage:Using with the steel seal cover board 9 for being oriented to steel pipe 10 and bolt hole, the cost of raw material adds
Greatly, scene processing is cumbersome, is oriented to 10 angle of steel pipe and is difficult to effectively control, when additionally mounted seal cover board 9 and former rubber pad ring,
It needs first to remove mooring cable at bollard, increases on-site installation work amount, also 11 collapsing length of rubber bellows is limited shadow
Ring mooring cable applying working condition.
Referring to Fig. 5,6 and 7, the third embodiment of the utility model, mooring cable 1, outside plate 3, leads cable at fairlead 2
The parts such as hole flanged plate 4, sealing mightiness belt 5, rubber washer 6, seal closure 7.
Seal closure 7 ensures airtight requirement using high-strength PVC airtight cloths.
Consider following two points when studying FLNG ship mooring encapsulating methods:
A, mooring cable 1 is whole hawser at each mooring point of ship, and mooring cable 1 passes through fairlead on ship plank 3
2, it is fixed respectively with bollard on harbour and ship, therefore mooring sealing operation is carried out again after the installation of mooring cable 1;
B, ship is considered in operating modes such as dynamic, tide and stormy waves variations, and ship mooring hawser can be with different operating modes
Top to bottom, left and right, front and rear are swung at fairlead, therefore when studying mooring encapsulation scheme, select high-strength PVC airtight cloths as close
Sealing cover 7, there are enough collapsing lengths, along fairlead flanged plate 4, entirely package two encloses 7 upper and lower end of seal closure for upper end, is sealing
7 mating interfaces, upper flanges interface sealing mightiness belt 5 are covered laterally, longitudinally wound, lower end and mooring cable 1 with sealing
Mightiness belt 5 is fastened, and 7 selection method of seal closure meets mooring cable when Ship dynamic situation, tide and stormy waves change,
Top to bottom, left and right, front and rear swing working condition requirement at fairlead.
Seal mightiness belt 5:Using the cloth base adhesive tape of 3M, sealing mightiness belt 5 be for the docking of seal closure 7, seal closure 7 with
Airtight to ensure used in fairlead 2, seal closure 7 and hawser 1 are fastened, sealing mightiness belt 5 alternately winds at least three layers.
Rubber washer 6:Using rubber packing, to ensure that 7 lower end inside of seal closure is sealed at mooring cable, centre uses
Rubber washer 6 reaches airtight, first with fluid sealant that rubber washer 6 is be bonded with mooring cable 1, then will be close with sealing mightiness belt 5
Sealing cover 7 alternates at least three layers of winding with rubber washer 6, mooring cable 1.At 7 lower end of seal closure and mooring cable 1 again
With sealing glue sticking, sealing is again ensured that.
Fluid sealant:Using strength AB fluid sealants, for adhesive rubber washer 6 and mooring cable 1,7 end of seal closure and it is
It moors and is sealed at hawser 1.
The research method taken:
It is first whole to consider how sealing and quick and easy for installation using method local after first entirety, cost is reduced, effectively
Quality is controlled, is then sealed the selection of cover 7 again, sealing mightiness belt 5 is selected, and rubber washer 6 is selected, and fluid sealant is selected.
The embodiment advantage:Using inventory and current material, selection is convenient, of low cost, quick and easy for installation, effectively
Control quality, it is ensured that when Ship dynamic situation, tide and stormy waves change, top to bottom, left and right, front and rear are swung mooring cable at fairlead
It can ensure to seal when operating mode.
In summary three kinds of schemes, the third embodiment thoroughly solve airtight and mooring cable working condition requirement, and
Cost is reduced, it is quick and easy for installation, quality is effectively controlled, shipowner and the consistent approval of ship inspection have been obtained.
