Experience in Float Over Integrated Deck - Design and Installation

J. H. Sigrist


Since early 1980, Technip-Geoproduction (TPG), as designer or as installation contractor, has been using with success the float over system “UNIDECK-TPG” for the transportation and installation of integrated decks for offshore platforms.

The concept offers the advantages of significant savings in transportation and installation cost by minimizing the installation time and offshore hook-up and eliminating the need for a heavy lift derrick barge.

The paper describes the technology used for the installation, the required engineering studies, the consequences of using such a concept on platform design and the selection of an appropriate barge size to be used.
