Abstract: Platform cost control is significant for economic profit of marginal oil field development.While platform installation is identified as a major cost driver, the minimal platform concept should fit well with development philosophy by decreasing capital expenditures and reducing the time required to bring new production.The assessment of three new installation schemes:small crane barge, jackup rig and self installing were given, and the technical and economical feasibility of such concepts were analyzed.Finally, a new so-called SSF (Suction-piled Stacked Frame) platform which combined with this 3 installation schemes are described.
