The method for lowering an object (1) to an underwater installation site (2), wherein a submersible remotely operated vehicle (ROV) (20) having at least one thruster for providing lateral thrust is interconnectable to an object (1), entails providing a vessel (10), having a winch (13) and suspension cable (14); interconnecting and lowering the object (1) and ROV (20) towards the underwater installation site using a suspension cable (14), providing at least one anchor (30) near the installation site; interconnecting each anchor (20) and ROV (20) with a positioning wire (32), while the ROV and object are suspended in the holding position; tensioning and adjusting the length of each positioning wire (32) such that the interconnected ROV and object are positioned with respect to the installation site; and further lowering interconnected object (1) and ROV (20), which are positioned by at least one positioning wire (32) onto the installation site while keeping the interconnected object and ROV suspended from the suspension cable (14).
