[0026] To make the objects, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0028] The conventional single-point system outer delivery adhesive floating hose usually adopts a full-floating hose configuration. The fixed single-point system is relatively fixed between the upper turret and the tower, and the upper turret structure cannot rise and sink with the change of the tide, so that the outer delivery adhesive hose floats on the sea surface along the length direction, but the connection part of the hose and the turret reciprocates with the change of the tide. The conventional floating hose configuration and the hose fatigue performance cannot meet the operation requirements.

[0029] Based on this, the following refers to the accompanying Figure 1 to the accompanying Figure 5 The present application discloses a semi-floating outer delivery adhesive hose and a marine operation system.

[0030] The present application discloses a semi-floating outer delivery adhesive hose and a marine operation system. Figure 1 As shown in the drawings, the semi-floating outer delivery adhesive hose comprises a floating section 1, a semi-floating section 2, and a sinking section 3 connected in sequence, the floating section 1 can float on the sea surface, the sinking section 3 can be immersed in seawater, the semi-floating section 2 is arranged between the floating section 1 and the sinking section 3, and the semi-floating section 2 is located between the highest tide level 100 and the lowest tide level 300.

[0031] The semi-floating type external delivery bonded hose adopts a three-section design, i.e. a floating section 1, a semi-floating section 2 and a sinking section 3. The floating section 1 is always above the sea level, so that the staff can observe the hose in real time. The semi-floating section 2 is arranged between the floating section 1 and the sinking section 3, so that the hose can rise and fall with the sea water under the action of the tide, thereby meeting the requirements of fixed single-point external delivery operation.

[0032] It should be noted that the floating and sinking state of the semi-floating section 2 of the hose changes with the tide during the external delivery operation, i.e. it is in a suspended state at high tide, and gradually transitions from the suspended state to the underwater state as the tide level decreases, until the elevation is at the lowest position at low tide.

[0033] Specifically, as shown in Figure 2 and Figure 3 , the floating section 1 of the hose is always floating on the sea level, and its position changes with the change of the sea level. A part of the semi-floating section 2 is close to the sea level, as shown in Figure 2 , when the sea level is at the highest tide 100, the position of the semi-floating section 2 is relatively high compared to the position when it is at the sea level reference 200, and when the sea level is at the lowest tide 300, the position of the semi-floating section 2 is relatively low compared to the position when it is at the sea level reference 200, and the sinking section 3 of the hose is always submerged under the sea level.

[0034] Further, as shown in Figure 1 and Figure 4 , the semi-floating type external delivery bonded hose further comprises a connecting section 4, the connecting section 4 is connected with the floating section 1, and the end of the connecting section 4 away from the floating section 1 is fixed to the mounting end of the oil tanker 5.

[0037] Further, the connecting section 4 further comprises a support section 42, the support section 42 is fixed to the round hole support of the oil tanker 5.

[0038] Specifically, the support section 42 comprises a support part 421 and a tail pipe part 422, wherein the support part 421 is connected with the transition section 41, and the support part 421 extends downward along the side wall of the oil tanker 5,

[0039] Further, as shown in Figure 1 and Figure 5As shown, the floating section 1 comprises at least two mutually communicating floating pipes 11, the interior of the floating pipes 11 is hollow and capable of floating on the sea level. The hollow structure enables the floating section 1 to float on the sea surface as a whole, and meanwhile, the floating section 1 as a whole can be made of light material, so that the floating section 1 is more easily to float on the sea level.

[0040] Alternatively, the floating section 1 can also be provided as a solid structure, and meanwhile, the floating section 1 as a whole is made of light material, or part of the floating pipes 11 is provided as a hollow structure and the rest is provided as a solid structure, in any case, it is only required to make the floating section 1 float on the sea level, which is not specifically limited herein.

[0041] Further, the floating section 1 is provided with an emergency shut-off valve 12 on the upper side, which is used to cut off the communication on both sides.

[0042] Specifically, the sinking section 3 is provided with a plurality of weights penetratingly arranged thereon, so as to immerse the sinking section 3 in seawater.

[0043] It should be noted that each hose of the floating section 1, the half-floating pipe 11 section and the sinking section 3 should be designed according to the buoyancy state in the external transportation operation, and the structure form and specification are not specifically limited herein.

[0044] Specifically, the pipeline fatigue performance of the sinking section 3 and the half-floating pipe 11 section can be designed according to the actual hydrological environment and tidal variation, which is not specifically limited herein.

[0045] Further, the floating section 1, the half-floating section 2 and the sinking section 3 are connected through flanges.

[0046] The embodiment provides a sea operation system, which uses the half-floating external transportation adhesive hose as described above.

[0047] The sea operation system is aimed at the characteristics that the existing fixed tower type single-point external transportation hose system is greatly affected by tidal variation, and innovatively adopts the half-floating external transportation adhesive hose system configuration, and further meets the requirements of fixed single-point external transportation operation by innovatively adopting the underwater hose for the fatigue sensitive area of the connection between the hose and the process pipeline of the rotary table.

[0048] Specifically, the total length of the half-floating external transportation adhesive hose should be designed according to the external transportation operation requirements and the main dimensions of the tanker 5, which is not specifically limited herein.

[0049] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description.
