MarineMasters has commissioned Orca Offshore to perform all maritiem analysis for the decommissioning of the South Angsi Alpha (SAA) Platform. The 4,000 mt four-legged SAA platform, a Mobile Offshore Application Barge (MOAB), served as a full production facility. After production ceased, it was to be removed and partially reefed per Malaysian regulations – making it the largest platform ever decommissioned and repurposed in Malaysian waters.
The removal was done by lowering the topside using strand jacks on a cargo barge. The jacket and other parts have been removed using a small crane vessel.
