Background

With the increasing difficulty of exploration and development of onshore oil and gas resources, the offshore oil and gas resources become main alternative energy and have received more and more attention. According to statistics, the ocean oil gas accounts for more than half of the newly found reserves of global oil gas in 2006. The ocean energy is vigorously developed, and the energy safety of the country can be powerfully guaranteed. In the process of ocean oil and gas exploitation, the riser is a link connecting a seabed wellhead with an offshore operation platform. When ocean currents flow through the riser, vortices which are alternately shed are generated on two sides of the riser, so that the riser vibrates, namely vortex-induced vibration, and the service life of the riser is shortened.

There are two main methods for suppressing vortex-induced vibration, namely active suppression and passive suppression. The active inhibition method disturbs the flow field structure by injecting external energy to inhibit the generation of vortexes, but has the defects of high installation difficulty, high energy consumption and the like, and is not widely adopted on site. The passive suppression influences the falling and development of the vortex by adding auxiliary devices such as a fairing, a spiral strake, a partition plate and the like, so that the effect of suppressing vibration is achieved. At present, a vibration monitoring device is mainly mounted on the surface of a vertical pipe, dynamic load response caused by vortex-induced vibration is monitored in real time, required electric energy is transmitted through a submarine cable, energy consumption is high, and monitoring failure can be caused when the cable is damaged. In view of the huge kinetic energy in the ocean current, the ocean current almost continuously moves all the year round, and is an inexhaustible clean energy.

Therefore, a device integrating vortex-induced vibration suppression, ocean current energy utilization and riser vibration monitoring is urgently to be developed, and the safety service of the riser is effectively guaranteed.
