Abstract: A collar for repairing a marine support has a tubular upper segment, a tubular lower segment, and a middle segment providing a transition region between the upper and lower segments. The collar can be opened and closed along a slit extending from the upper end of the collar to the lower end of the collar.

The upper end of the collar is secured to the extension, and the lower end of the collar is secured closely along the perimeter of the pile. A flowable fill material is then injected into spaces between the collar and the marine support, filling or encasing voids or damaged areas on the marine support.

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.
