| Summary: | The idea of using float-over installations for minimalfacilities platforms was shown to offer significant advantages,especially when coupled with a substructure installed by a jackuprig. Recently, float-over installations of minimal facilitieshave been conducted by the cantilevered method by ICONEngineering PlY Ltd (ICON). The operation involves theplatform topsides being loaded and transported to site on abarge, skidded over the barge bow, and lowered onto the jacket.The paper presents results of a research project undertaken bythe Australian Maritime College (AMC) in conjunction withICON, with the objective to investigate motions of a barge andloads exerted on the jacket when the two are docked togetherfor a smooth load transfer operation. The model of aninstallation barge has been tested in the AMC wave basin andresponse amplitude operators of the barge motions have beendetermined for both the free floating and docked conditions. Arange of wave periods and heights has beeninvestigated. Modeltest results have been used to verify numerical predictions usedin the design, and to get insight into uncertainties, which mayotherwise be difficult to assess using standard software. |
