Method for lowering an object to an underwater installation site using a ROV

摘要

A method for lowering an object (1) to an underwater installation site (2), wherein use is made of a submersible remotely operated vehicle (ROV) (20) comprising at least one thruster (21), which ROV is connectable to the object. The method comprises: lowering the object into the water and suspending the object in a beneath water surface position; independently from lowering and suspending the object, lowering the ROV into the water and suspending the ROV in a beneath water surface position; interconnecting the object and the ROV while in the beneath water surface position; and further lowering the interconnected object and ROV towards the installation site.
