Compared with the traditional skid shoes transport, SPMT (Self-propelled modular transporter) is more advantageous when transporting an off-shore structure to the ship because of its flexible operation and less site restriction. It is the first time for CNOOC to introduce SPMT in actual project, which replaced the traditional load-outs by skid shoes. In this paper, the main loads applied on SPMT, as a foundation, have been studied at the head. Combined with existing cases, new support forms of living quarter suitable for SPMT have been discussed. This innovative technology is of great significance for improving productivity, solving the issue of shipment queuing at site and realizing cost efficiency.
