Abstract

Method for transfer and connection operation of a bulk hose between a vessel and an offshore drilling or operating platform, the system comprising a hose, means for storage of the hose onboard the platform and connecting means onboard the vessel for secure connection of the hose to the ship, wherein a forerunner connected to the hose end to be connected to the ship brought into interaction with a catching device connected to the connecting means, and the forerunner is pulled in to bring the connector at the end of the hose into interaction with the connector in the connecting means, is described. A device for performing the method and part of the system are also described.

Claims

1. A method for temporarily coupling of a hose to a pipe system, where a first coupling part is connected to the hose, and a second coupling part is connected to the pipe system, where both the first and the second coupling part comprises valves that automatically closes when said first and second coupling parts are not connected to each other, wherein said first and second coupling part are brought into interaction with each other to establish a tight connection before the valves in the coupling parts are opened and where the coupling parts are locked to each other.

2. The method according to claim 1, wherein the valves are opened by interaction of the valve parts of the first coupling part and the valve parts of the second coupling part.

3. A hose connection device for temporarily coupling of a hose to a pipe system, the connection device comprising a first coupling part connected to the hose, and a second coupling part connected to the pipe system, where both coupling parts comprises valves that are automatically closed when the coupling parts are not connected to each other, wherein a part of one of the coupling parts is designed to be inserted into the other coupling part to form a tight connection, and where the parts of the valves in the coupling parts are designed to interact with each other to open both valves after the tight connection is formed.

4. The hose connection device according to claim 3, the first coupling part comprising a tubular main body (101) having a connection branch (102) for connection to a hose in one end and a connection part (103) for connection to the second coupling part, in the other end, wherein a check valve is formed by a mainly axially displaceable valve cone (105) is designed to interact with a conical valve seat (106) formed in the inner wall of the main body (101) close to connection part (103), where both cones have their smallest diameter closest to the connection part (103).

5. The hose connection device according to claim 3, wherein the valve cone (105) is forced against the valve seat (106).

6. The hose connection device according to claim 3, wherein the second coupling part (200) comprises a mainly cylindrical part (203, 207, 212) designed to be partly inserted into the connection part (103) of the first coupling part (100) and to form a tight connection with said connection part.

7. The hose connection device according to claim 3, wherein the second coupling part (200) comprises an axially displaceable and mainly tubular valve seat member (213), designed to interact with a valve cone (211) on an mainly axially arranged bolt (210).

8. The hose connection device according to claim 7, wherein valve seat member (213) is designed to interact and form a tight connection with the connecting part (103) of the first coupling part (100), where the valve seat member (213) is designed to open the valve in the second coupling part (200), and that the bolt (210) is designed to interact with the valve cone (105) to open the valve in the first coupling part (100) as as the connection parts are forced together.

9. The hose connection device according to claim 4, wherein the second coupling part (200) comprises a mainly cylindrical part (203, 207, 212) designed to be partly inserted into the connection part (103) of the first coupling part (100) and to form a tight connection with said connection part.

10. The hose connection device according to claim 5, wherein the second coupling part (200) comprises a mainly cylindrical part (203, 207, 212) designed to be partly inserted into the connection part (103) of the first coupling part (100) and to form a tight connection with said connection part.

11. The hose connection device according to claim 4, wherein the second coupling part (200) comprises an axially displaceable and mainly tubular valve seat member (213), designed to interact with a valve cone (211) on an mainly axially arranged bolt (210).

12. The hose connection device according to claim 5, wherein the second coupling part (200) comprises an axially displaceable and mainly tubular valve seat member (213), designed to interact with a valve cone (211) on an mainly axially arranged bolt (210).

13. The hose connection device according to claim 6, wherein the second coupling part (200) comprises an axially displaceable and mainly tubular valve seat member (213), designed to interact with a valve cone (211) on an mainly axially arranged bolt (210).
