State of the Art and Some Key Techniques for Offshore Floatover Installation

The heavy lift technology is a traditional installation method for integrated topside installation.But the availability and capacity of such heavy lift vessels restricted the application.Floatover method is becoming a preferred offshore topsides installation method and has been successfully applied to offshore installations of integrated topsides onto different fixed and floating platform substructures.This paper presents a comprehensive overview of floatover installation and the primary equipment systems.Floatover installation examples in domestic and abroad are summarized and listed.And the key technologies of floatover installation are summarized.Finally,a floatover analysis is demonstrated based on a practical engineering installation.
