ABSTRACT:
A method of installing an offshore platform. The superstructure is assembled and completed in advance in a fabrication yard. The superstructure with a floating body attached thereto is transported to the area of the sea where a jacket of the platform has been erected by towing the superstructure while floating on the sea. It is made to sink by pouring sea water into the floating body and installed on the top portion of the jacket which is situated under the sea level. An extension is attached to the jacket in advance such as to project above the sea level during the piling operation and thereafter it is removed such that the top portion of the jacket is brought to a position below the sea level.
