Loading of Offshore Structure on Barge Using SPMT
Abstract
Load-out is one of critical part during construction of an offshore structure and one of the load-out methodology is load-out by using SPMT (Self Propelled Modular Transporter). SPMT can transport to the uneven ground condition by using hydraulic system. Three point suspension set-up and four point suspension set-up are two common levelling hydraulic system on SPMT. There is a significance difference during preparation of SPMT on each levelling system in term of time and cost. This study aims to analyse the structural integrity of offshore structure including barge response during load-out transportation. This study compares load-out transportation arrangement between each levelling system during cross over to the barge by using simulation. Transportation analysis to check offshore structural integrity during cross over to the barge is done by Staad Pro and PIAS software. Three point suspension set-up is more safely used for super heavy weight structure and four point suspension set-up is better for normal and intermediate heavy weight structure with considering cost, time and productivity to setting the suspension set-up and transportation arrangement
