Abstract: A transfer system is described including a subsea installation fixed relative to a seabed, and a transfer element for transfer of fluid, electrical signals, or electric current between the subsea installation and a floating arrangement. The transfer element is configured to connect to the subsea installation and includes a connector for connecting to the floating arrangement. The transfer system includes a buoyancy element anchored to the seabed, and has a through-going hole in the vertical direction. The transfer element extends through the hole and is movable in both directions through the hole. The transfer element includes a fender system that extends at least partially around the circumference of the transfer element. The fender system abuts the buoyancy element when the transfer element is suspended. When the transfer element is suspended, the transfer element forms an S-shape or J-shape between the subsea installation and the buoyancy element.

Abstract: A transfer system is described comprising a subsea installation (4) which is fixed relative to the seabed (1), and at least one transfer element (5) for transfer of at least one fluid and/or electrical signals and/or electric current between the subsea installation (4) and a floating arrangement (3). The transfer element (5) is arranged for connection to the subsea installation (4) at a first end and comprises connecting means for connecting to the floating arrangement (3) at its free end (7). The transfer system further comprises a buoyancy element (31) which is anchored to the seabed, and is provided with at least one through-going hole in the vertical direction. The at least one transfer element (5) extends through the at least one hole in the buoyancy element (31) and is movable in both directions through the at least one hole.

Abstract: An axially flexible sealing device connecting two pipeline ends which comprises a number of sealingly connected annular members, each annular member including an inner cylindrical member, two spaced apart outer cylindrical members, and separate flexible ring members connecting the outer cylindrical members to the inner cylindrical member, each outer cylindrical member having a portion extending axially beyond the adjacent end of the inner cylindrical member when the attached flexible ring member is in an untensioned state. The sealing device is designed for use in connecting two pipelines located beneath sea level wherein the end of one of the pipelines is located in a hollow structure and one of the sealing devices is connected thereto, whereas the other end of the sealing device is sealingly connected to one end of a penetration sleeve which is sealingly connected through the wall of the structure (the other end of the sleeve being connected to the end of the other pipeline).
