In an offshore system having a floating vessel, a turret within a hull opening, and a bearing assembly including a support row assembly axially transferring the weight of the turret to the vessel and allowing the vessel to weather vane about the turret, a method and arrangement for in situ remediation of a damaged support row assembly. An outer upper ring is removed from an outer lower ring and a support ring is installed on the outer lower ring. A lower race and support rollers of a remedial support row assembly are installed on the support ring. A reaction ring is positioned above the support ring and connected to an inner ring secured to the turret. The inner ring is axially displaced relative to the outer lower ring and the turret axial loading is transferred to the remedial support row assembly between the support ring and the reaction ring.

An aft-mounted dive platform system includes at least one hull portion rigidly affixed to a hull of a boat. A dive platform is slidably attached to the at least one hull portion and is positioned, at least partially, behind at least one propeller drive system affixed to the stern of the boat. An actuation system is configured to effectuate essentially vertical displacement of the dive platform with respect to the at least one hull portion. An interface system is configured to couple the actuation system with a rotation system for the at least one propeller drive system.

An aft-mounted dive platform system includes at least one hull portion rigidly affixed to a hull of a boat. A dive platform is slidably attached to the at least one hull portion and is positioned, at least partially, behind at least one propeller drive system affixed to the stern of the boat, thus allowing for essentially vertical displacement of the dive platform with respect to the at least one hull portion.

An aft-mounted dive platform system includes at least one hull portion rigidly affixed to a hull of a boat. A dive platform is coupled to the at least one hull portion and is positioned, at least partially, behind at least one propeller drive system affixed to the stern of the boat. The dive platform includes at least one clearance panel configured to allow access to the at least one propeller drive system in the event that the at least one propeller drive system needs to be serviced.

An aft-mounted dive platform system includes at least one hull portion rigidly affixed to a hull of a boat. A dive platform is coupled to the at least one hull portion and is positioned, at least partially, behind at least one propeller drive system affixed to the stern of the boat. The dive platform includes at least one clearance panel configured to be displaced in the event that the at least one propeller drive system rotates upward due to running aground.

An aft-mounted dive platform system includes at least one hull portion rigidly affixed to a hull of a boat. A dive platform is coupled to the at least one hull portion and is positioned, at least partially, behind at least one propeller drive system affixed to the stern of the boat. The at least one hull portion includes a first hull portion and a second hull portion. The first hull portion includes: a first inner portion surface positioned proximate a first side of the at least one propeller drive system and a first Outer portion surface positioned proximate a first outer surface of the hull of the boat; wherein the first outer portion surface of the first hull portion is recessed with respect to the first outer surface of the hull of the boat.

The invention relates to a method for handling a load, in particular a blade, of an offshore wind turbine system comprising a wind turbine, wherein a crane is temporarily mounted on the platform, the crane having a tower of which a plurality of elements can be telescoped relative to each other. The invention also relates to a crane and to devices suitable for carrying out this method.
