Abstract

Flexible pipes are important facility for offshore oil and gas development. Vertical laying technology is a high-speed and efficient method for flexible pipes laying operation, which has been widely used in deepwater development projects in the world. The advantages o fvertical laying in deepwater is analyzed by comparing the two typical laying methods for flexible pipes. The type and system components, structural and layout characteristics, and suppliers for designing and manufacturing vertical laying system are summarized. The future development trend and localization suggestions of vertical laying system is analyzed, which can provide a useful reference for the independent development of vertical laying system equipment in China.

Key words： deepwater flexible pipe; flexible pipe lay; vertical lay system; pipe lay vessel; localization
