Abstract

Following advancements in the offshore technology, facilities required have resulted in heavier topside loading for recent platform designs. However, the lift crane vessels conventionally used for deck (topside) installation is not up to par. In other words, conventional installations are no longer capable of catering to the offshore industry requirements. Thus, giving rise to the need for floatover installation that provides significant advantages over other methods of deck installation for heavy topsides, especially in areas of the world where access to heavy construction equipment, trained labour and supplies are not readily available or reliable. Due to the relatively foreign technology of floatover installation, research efforts are being made to understand the motion responses of a floatover barge during its entire operation from standby to mating of topside and support legs to exit. Therefore, this project is a collaboration between Technip Geoproduction (M) Sdn Bhd and Universiti Teknologi Petronas (UTP) to conduct research on the floatover installation used for a fixed jacket structure, Owez ODP-A in the Caspian Seas. The research will be done mainly using model tests and numerical analysis. From model tests and numerical analysis, resulting RAO of the barge model along with the corresponding motion response will be analyzed to fully understand the loads triggered by environmental loadings and the resulting barge motions. With that understanding, the series of ballasting load for transfer of topside onto jacket legs can be determined to ensure minimum barge impact toward the fender system at the substructure. This knowledge can then be utilized to mature floatover installation for jacket structures in Malaysian seas, an unprecedented method for our regwn.
