[0002] Offshore oil and gas development is one of the main contents of today's marine development projects. Piers are often used between offshore platforms to achieve resource sharing and optimize equipment and facilities. Jack-up platforms are the main equipment for offshore oil and gas exploration and development. When a jack-up offshore platform moves to the target sea area for production operations and needs to be connected to an external wellhead platform, the jack-up offshore platform can communicate oil, gas, water, and electricity with the wellhead platform through the pier. At the same time, the pier also serves as a flow channel for staff. Due to the influence of the marine environment, the jack-up platform and the wellhead platform will have relative displacement, which has an adverse effect on the connection between the pier and the oil pipe hose and the passage of staff.

[0031] like Figures 1 to 3As shown, the adjustable marine platform trestle provided by the utility model comprises an adjusting base and a trestle body. The adjusting base comprises two base outer plates 4, two support plates 5, a bottom plate, a limiting shaft 6, a damping spring 7, a guide wheel 8, a rotating pin hole 9, and a hydraulic device 10. A limiting shaft 6 is provided at one end of the adjusting base, and the limiting shaft 6 is connected to the base outer plate 4 and the support plate 5. A rotating bracket 3 is installed at the other end of the adjusting base. The base outer plate 4 is provided with a rotating pin hole 9. The axis of the rotating bracket 3 is connected to the rotating pin holes 9 on the base outer plate 4 and the support plate 5. One end of the damping spring 7 is installed on the side wall of the base outer plate 4, and the other end is connected to the guide wheel 8. The support plate 5 is provided with a limiting groove, and the trestle baffle 12 can pass through the limiting groove. One end of the hydraulic device 10 is installed on the bottom plate, and the other end can push the trestle baffle 12, which is located below the main box of the trestle.

[0032] There are more than two damping springs 7 arranged longitudinally and more than two vertically. The trestle body includes a main trestle box 11, a trestle baffle 12, a trestle side plate, a baffle reinforcing rib 13, a guide rail 14, a limit hole 15, and a guardrail 16. The main trestle box 11 has two layers, including two layers of horizontal plates and three longitudinal plates. The trestle baffle 12 is arranged below the main trestle box 11. The baffle reinforcing rib 13 is arranged behind the trestle baffle 12 to support the trestle baffle 12. The trestle side plate is provided with a limit hole 15 and is connected to the limit shaft 6. The guardrail 16 is installed on both sides of the main trestle box 11. The trestle side plate is provided with a guide rail 14, and the guide rail 14 is connected to the guide wheel 8. The two adjustment bases are respectively connected to the self-elevating platform deck 1 and the wellhead platform deck 2, and are connected to the trestle body. The adjustment base is rotated by the rotating bracket 3, and the rotating bracket 3 is installed on the self-elevating platform deck 1.

[0033] Furthermore, the trestle body is in a vertical state when not in operation.

[0034] Furthermore, when the self-elevating platform moves to the target sea area for production operations and needs to be connected to an external wellhead platform, the self-elevating platform crane is connected to the rotating pin hole 9 at the wellhead platform end, and the crane is used to rotate the adjustment base and the pier body around the rotating bracket 3 for lowering.

[0035] Furthermore, after the main body of the trestle is lowered, the adjustment base at the wellhead platform end is fixed.

[0036] Furthermore, the lower layer of the main box body 11 of the trestle is for the passage of oil pipes and hoses, so that oil, gas, water and electricity can be communicated between the self-elevating platform and the wellhead platform. The upper layer of the main box body 11 of the trestle is a passage for staff, and the guardrails 16 on both sides of the trestle protect the safety of passers-by.

[0037] Furthermore, when the self-elevating platform and the wellhead platform generate longitudinal relative displacement, the hydraulic device 10 loads the trestle baffle 12 to push the trestle baffle, thereby adjusting the longitudinal displacement of the trestle body.

[0038] Furthermore, when the jack-up platform and the wellhead platform generate a lateral relative displacement, the guide wheel 8 connected to the damping spring 7 cooperates with the guide rail 14 on the outer plate of the trestle to adjust the lateral displacement of the trestle body.

[0039] When the jack-up platform operation is completed, the fixings of the adjusting base at the wellhead platform end are removed.

[0040] Furthermore, the self-elevating platform crane is connected to the rotating pin hole 9 at the wellhead platform end, and the adjusting base and the trestle body are rotated around the rotating bracket 3 by the crane to be retracted.
