Vietsovpetro successfully develops offshore hydrocarbon deposits located on Block 09-1 of the South Vietnam Shelf. At present, about 50 offshore facilities operate in Vietsovpetro. In the future, it is planned to build more than 10 wellhead platforms, with applied unmanned technology. Improving the efficiency of the enterprise lies in the field of optimization of offshore facilities and field infrastructure. The key to success is the comprehensive implementation of various measures that can have both an economic and a safety effect. At present, the company is in need of expanding the possibility of safe transfer of personnel from vessels to unmanned wellhead platforms of Vietsovpetro, since today the personnel is being delivered by helicopter, transfer basket or crane equipment. It is known that workers transfer using basket and crane located on the platform requires significant time, involvement of maintenance personnel and is not safe compared to the use of special transfer devices. Besides, waiting on crane by the vessel with dynamic positioning system leads to additional fuel costs. The article describes the possibilities of optimizing the current logistics scheme of passenger turnover at Vietsovpetro fields by implementation of the modern and safe transfer method – Walk-to-Work (W2W) systems, gives an idea of these systems and global application experience. W2W offers personnel a convenient opportunity to move from the side of the vessel to the offshore structure and vice versa without the use of vertical stairs and ladders. The phrase itself draws a parallel between the usual walk and the transition to the platform, emphasizing the ease and safety of this procedure. Unlike helicopter, which requires flight schedule adjustment, vessel-platform crossing system allows using these vessels for transfer “on demand” basis, almost immediately upon request if necessary. In addition, the use of this system can significantly reduce the cost of expensive helicopter maintenance. References 1. DNVGL-ST-0358.
