Provided is a method for moving an object between a platform of a wind turbine and a deck of a vessel, wherein the platform is located at a tower the wind turbine, wherein the object is moved vertically by a hoist coupled between the object and at least one fixation site the wind turbine located above the platform and the deck, wherein the object is deflected radially from the tower by a puller coupled between the object and the vessel.

A method is for placing an object on a seabed. The method includes connecting the object to at least two vessels by use of a work wire; attaching one or more buoyancy devices to the work wire, to achieve a distributed buoyancy of the work wire that forms a double curvature which disassociates at least some vessel movement from the object, to allow for controlled movement of the object; and co-operating the vessels to move the object into a position in a sea distant from the vessels, to lower the object to the seabed and to place the object on the seabed. Also described is a system for transporting an object to a position in a sea where the water comprises gas bubbles significantly lowering the load-carrying capacity of the water and for lowering the object to an area having a wellbore from which the gas bubbles enter the sea.

An autonomous loading/unloading system and method for transferring material includes: a buoy for releasing onto water; a messenger line coupled to the buoy for being pulled; a carrier line loop coupled to the messenger line for being pulled, where a payload is coupled to the carrier loop for transferring the material to or from an unmanned ship; a fetch/release platform to fetch or release the payload from or onto the water; a loading/unloading dock for the payload; a plurality of line guides for guiding the carrier loop; and a platform-to-payload interconnect for autonomous loading or unloading of the material from/to the payload.
