The invention relates to a method for installing anchors on the bottom of the sea. Wires (4) and a suction anchor (2) are attached to a frame (1). Through the centre of the frame's vertical axle a mounting device (6) for an anchor holder (7) is placed. The frame (1) works as a driving ramp for different shaped anchor holders and anchors (5, 15, 20). With the mounting device (6) the anchor penetrates the bottom of the sea at a certain position. A remote operated vehicle (ROV) and/or a hydraulic motor and pump gives a hydraulic torque for boring, screwing, pressing and stamping effects. A helical screwanchor is used for rotary screwing into the bottom of the sea (3). The span and the gradient are varied given to geological data for achieving holding forces. After use the anchor is released with a releasing mechanism (13, 14) and is left on the bottom of the sea.
