China. Following transportation to site, MOPA deck will be installed by lifting from the transportation barge. A total of four lift points will be used for installation. The padeye design and stress check for LD32-2 MOPA deck is performed according to API RP 2A and AISC WSD codes. The lifting arrangement and details are shown in drawings LD32-2-DWG-MOPA-ST-1006. Calculated padeye reactions and lift analysis is detailed in Report LD32-2-RPT-MOPA-ST-1006. The results of this calculation indicate that the padeyes are adequate for lifting condition.
