Abstract
For the marginal oilfield with low oil extraction, adding wave energy conversion device integration to the jacket platform is very meaningful for reducing the mining cost. Firstly, the design concept of integrated OWC device with jacket platform is proposed. Then, the optimal model of OWC device structural arrangement parameters is established with the aim of low wave force and high wave energy conversion efficiency. Finally, the dynamic response of integrated device is analyzed under the working sea state and extreme sea state. The results show that integrated device has certain effectiveness and feasibility.
Highlights
With the development of society, the demand for energy continues to increase, and the reserves of conventional petrochemical energy such as coal and oil are decreasing, and the energy crisis is increasing (Cheng et al, 2009)
In this paper, based on the design data of a jacket platform working in JZ-20 oil field in Jinzhou, Liaoning province in China, an oscillating water column (OWC) device integrated into the jacket platform is proposed, the optimal structure parameters of OWC device are determined, and the dynamic responses of platform with and without OWC device are compared under the working and extreme conditions
The main conclusions are obtained as follows: (1) The wind load accounts about 75 and 89.8% of the total displacement of the jacket platform under working and extreme conditions, respectively, which indicates that the wind load dominates the dynamic responses
Summary
With the development of society, the demand for energy continues to increase, and the reserves of conventional petrochemical energy such as coal and oil are decreasing, and the energy crisis is increasing (Cheng et al, 2009). Radius d1 = R2 − R1 and the draft depth of device d, the effects of structural parameters on the wave energy capture efficiency of OWC device and the corresponding subjected wave force are studied.
