Definitions

  • the present invention relates to the use of a loading hose for transferring fluids between a first and second reservoir offshore.
  • the loading hose is used to transfer hydrocarbons to a tanker from a loading buoy, from a floating production and/or storage unit (FPSO / FSO), or from a loading unit (e.g. cargo transfer vessel - CTV).
  • FPSO / FSO floating production and/or storage unit
  • a loading unit e.g. cargo transfer vessel - CTV
  • a floating loading hose which typically extends from a loading buoy.
  • the end of the loading hose is provided with a loading hose coupling and is lifted onto the tanker, where a connection is made between the loading hose coupling and a receiving connection flange on the tanker.
  • a crane arranged on the tanker In order to hoist the end of the floating loading hose onto the tanker, a crane arranged on the tanker is used. To do this, the crane hook must be connected to the floating hose. This connection is typically made manually with personnel on a tug or a workboat. The personnel must typically get hold of a lifting chain arranged on the floating hose end, and connect the lifting chain to the crane hook.
  • Patent application publication WO2014083056 discloses a solution for connecting a mooring line from a floating structure, such as a ship, to a structure situated on the seabed, typically an anchor installed in the seabed.
  • a guideline extends from the ship down to a wire tackle attached to the anchor, and back up to the ship.
  • One end of the guideline is connected to a winch on the ship for pulling in the guideline, while the other end connects to a mooring line.
  • the mooring line is paid out while the guideline is pulled in.
  • GB2461713 discloses a marine connection system that includes a floating winch structure with a winch line that is suspended in a floating member adjacent the winch structure.
  • a surface cable is to be connected to a cable on the seabed.
  • the which line is connected to a further line that extends from a buoy and down to the cable on the subsea. By pulling the winch line, the subsea cable is lifted up to the surface cable.
  • US20140034137 presents an offshore fluid transfer system on a ship, and thus relates to the same field as the present invention.
  • a pulling line and an overhanging crane beam are used to move the end of an articulated fluid pipe into engagement with the fluid interface of an adjacent ship.
  • the articulated fluid pipe absorbs mutual movement between the two ships. Notably, except for the two ships themselves, no part of the fluid transfer system is in contact with the seawater.
  • An object of the present invention may be to present equipment and a method that may reduce the risk for personnel injuries and/or to increase the operational limits.
  • a loading hose connection assembly having a pull-in line, a floating part, and a connecting part.

  • the connecting part comprises a second locking element configured to enter into locking engagement with the first locking element, a pull-in line connection interface, a crane string connection interface.
  • the pull-in line extends from the pull-in line connection interface to the pull-in line guide element, and further to a pull-in section of the pull-in line, such that a pull in the pull-in section pulls the connecting part into the connecting part reception interface, thereby enabling a locking engagement with the floating part.
  • the pull-in section of the pull-in line, which is pulled, is a portion of the pull-in line, which is outside the floating part and the connecting part.
  • the pull-in section can be on a tanker or another ship.
  • the connecting part reception interface can be arranged in a receiving body with an entrance aperture, wherein the first locking means is arranged between the entrance aperture and the pull-in line guide element.
  • the first locking element and the second locking element can in some embodiments be configured to automatically enter into a locking engagement when the connecting part is pulled into the connecting part reception interface. This means that no other actuation of the locking elements will be necessary in order to establish the locked connection between the floating part and the connecting part. In other words, the connecting part is pulled into the locking engagement by means of the pull-in line.
  • the floating part may further comprise a pull-in line return channel.
  • the pull-in line may enter the floating part through an entrance aperture, and exit the floating part through the pull-in line return channel.
  • the connecting part reception interface and the pull-in line return channel may both have a straight, elongated extension, wherein the mutual angle between their respective axially extending center axes may be less than 30 degrees.
  • the pull-in line return channel may have a return channel aperture and the floating part may further comprise an auxiliary return aperture, which is configured to guide the pull-in line out of the floating part.
  • the pull-in line may be returned out from the assembly without extending through the pull-in line return channel.
  • the use of the auxiliary return aperture will typically be used when the pull-in of the connecting part is performed from a tug. In such situations, there may be a significant angle between the portion of the pull-in line extending into the assembly and the portion that returns out from the assembly.
  • a method of providing, by using the loading hose connection assembly according to the first aspect of the invention, a connection between a crane hook of a ship crane and a floating loading hose floating in the sea, and lifting the loading hose onto a ship comprises the following steps:
  • step c) may comprise pulling the pull-in section from a position on the same ship as on which the ship crane is mounted. That is, in such embodiments, the part of the pull-in line that extends out from the connection assembly and which is pulled, is pulled from a position on a ship, on which the crane is positioned.
  • a ship may typically be a tanker, onto which fluid shall be loaded through the loading hose.
  • step c) may alternatively comprise pulling the pull-in section from a position on another ship than the ship on which the ship crane is mounted. Such an embodiment will be discussed in one the examples below.
  • the actuation of the locking function may take place by operation of the pull-in line. I.e. by a pull in the pull-in line, so that the two parts are mated together into a locked position.
