Abstract

A method and a device for launching, submerging, positioning and installing of a structure (1) to another sub sea installation. The structure (1) is to be fixed in correct position and with a correct orientation related to the installation (2). At least one guiding line (3) is/(are) in advance fastened to the sub sea installation (2) in a fastening device (4), and is led through suitable openings (5) in the structure (1), and the structure is adapted to be lowered down along the guide line (3) towards the sub sea installation (2). When the method according to the invention is carried out, the structure (1) will, previous to the launching and submerging steps, be provided with at least one further control line (6) which in turn is provided with a tightening means (7) and the ends of the control line(s) (6) will, after the lowering process, be fastened to suitable designed anchorage points (8, 9) onthe sub sea installation (2), whereupon the tightening means (7) is/(are) operated so that the control lines (6) are tightened. The structure (1) is then guided along the tightened control lines (6), down upon the sub sea installation (2) and fixed in correct position and with correct orientation to this. e.g. by means of pre-positioned fastening poles (10, 11).
