Abstract: An installation arrangement with a barge and a jack-up rig which floats in a first position on the sea and has a hull which is slotted vertically from the surface of the sea and has a slot width which is greater than that of the barge so that the barge can move into a slot, wherein the jack-up rig has supporting legs which can move to and from along a height relative to the hull and can be set down on the seabed. The hull and the barge can be lifted along the support legs. The slot extends along the entire longitudinal extent of the barge over the entire height of the hull, and securing means are arranged on the barge and on the slot and said securing means interact and secure the barge in the raised position in a fixed position on the jack-up rig.

Abstract: An offshore platform with at least one pile of a pile foundation with an outer wall having an external diameter and with a tube (8, 12) with an inner wall having an internal diameter which is greater than the external diameter, on the exterior of which attachments are arranged, and which is slid over the pile (2, 3) driven into the seabed (4), wherein at least one spacer (20) is provided between the outer wall of the pile (2, 3) and the inner wall of the tube (8, 12).

Abstract: A method for foundation of a transformer platform having at least four piles (12), in which precisely one pile driver (1) is brought to the location, the pile driver (1) is supported on the seabed (9) by means of extendable supporting legs (7), driving jigs (11) are attached to the pile driver (1), the piles (12) are inserted through the associated driving jigs (11), the piles (12) are successively driven into the seabed (9) whilst maintaining the position of the pile driver (1), upper ends of the piles (12) driven into the seabed (9) are arranged level with or above the associated driving jig (11), the supporting legs (7) of the pile driver (1) are retracted and the pile driver (1) is moved away from the location.

Abstract: The invention relates to a rescue device for a container (7) having container corners (9) loaded onto a damaged ship (110), comprising a crane (50) arranged on a carrier (20, 21, 22), wherein the crane (50) has a front support arm (51), over which a load cable is guided, whose section leading away from the support arm (51) is connected to a container (7) to be unloaded, and the length of which can be changed. The invention is characterized in that the carrier (20, 21, 22) has at least one locking mechanism (204, 205) located opposite the crane (50), by means of which the carrier (20, 21, 22) is temporarily fastened in a releasable manner at the container corners (9) of at least one of the containers (7) fastened on the deck (1) of the damaged ship (110).
