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.
