FIELD OF INVENTION
[0001] The present inventions relate generally to a shackle assembly and a method for installing and/or releasing the shackle assembly subsea. The shackle assembly of the present invention comprises first and second plates mounted on either side of a shackle body eyelet and a shackle pin mounting assembly for use in mounting a shackle pin using a shackle pin pulling tool.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0008] The design involves modifying an industry standard shackle (Crosby) in such a way so that the shackle pin can be removed subsea with the use of a remotely operated vehicle ("ROV"). The benefit of the specific design is that the hydraulic mechanism used by the ROV to remove the shackle is installed and retrieved subsea separate from the shackle body by the ROV. The present invention allows multiple subsea shackles to be operated with the use of a single hydraulic shackle pin removal or installation tool.
[0009] This renders the device less prone to damage of critical parts of the pin removal mechanism during the subsea lifting/installation process. In addition to the above it provides with the option/capability to retrieve the shackle pin removal or installation mechanism to the surface for repair in case of a subsea failure. A single shackle pin removal or installation mechanism may be used on multiple shackles.
[0010] The above is important on critical offshore lifting operations especially when removing large shackles that have been heavily loaded during the lift as the pins can be difficult to remove by use of the ROV alone or a standard industry spring assist.
[0011] The design is based on using the standard shackle body and fabricating a modified shackle pin incorporating a grooved end which will be used to pull the pin out of the shackle body in order to disengage the shackle from the subsea structure padeye.
[0012] hi one preferred embodiment, the design also incorporates a flanged connection around one of the two "lobes" of the shackle body that is used to provide for a steel structure to react the linear pull load required to pull the pin out of the shackle. This structure also acts as a "guide" aiding in installation of the hydraulic "pin pulling" mechanism by the ROV. An advantage of the present invention is that prior art shackles may be modified as explained herein without altering the original load certification.
[0013] hi one preferred embodiment, the design is completed by a locking plate that is designed in such a way so as to secure the modified pin into the shackle, this is done in order to ensure that the shackle stays securely attached to the subsea structure padeye. This attachment offers a degree of integrity similar to that produced by a traditional cotter pin arrangement.
[0014] In one preferred embodiment, the locking plate is designed in such a way so that it is ROV removable. The plate will require removal by the ROV prior to engaging the hydraulic "pin pulling" mechanism.
