Abstract: An interface within a gas turbine engine includes a multiple of segmented components, each with a segment flange with a multiple of apertures, at least one of the multiple of apertures a first slot aperture. A full ring component with a ring flange that defines a multiple ring of apertures, at least one of the multiple of ring apertures a second slot aperture, the second slot aperture transverse to the first slot aperture.

Abstract: A rigid U-shaped structure sized to be closely received on the tip end of the transfer hook. One side of the U-shape of the structure is closed. A padeye is rigidly attached to the end curved portion of the U-shape of the structure. Means for holding the U-shaped structure in position on the tip end of the hook is provided. The holding means may be threaded bores through one or both sides of the U-shaped structure that allow bolts to be threaded through the holes such that they create sufficient friction against the tip end of the transfer hook to hold the U-shaped structure in position. The holes through the U-shaped structure may be unthreaded with threaded nuts rigidly attached to the U-shaped structure such that the nuts are aligned with the holes to allow bolts to exert pressure against the tip end of the transfer hook in the same manner to hold the U-shaped structure in position on the transfer hook.

Abstract: A mechanically releasable shackle pin arrangement that is readily operated by an ROV and is not affected by the hydrostatic pressures encountered at depth. A shackle body having two ends has a shackle pin received through bores at one end of the shackle body. A shackle nut threaded on the shackle pin secures the shackle pin in an installed position through the bores in the shackle body. An anti-rotation link plate is attached to the shackle body. The anti-rotation link plate extends to one end of the side plate. The shackle pin extends through bores at one end of the shackle body and the anti-rotation link plate and is secured in its installed position by a shackle nut threaded on the shackle pin. Means for preventing rotation of the shackle nut and loss of the shackle nut is provided on the anti-rotation link plate such that the shackle pin can be removed by a remotely operated tool on an ROV at depth to release a load without the need for hydraulics on the shackle assembly.
