针对深远海能源开发所处环境复杂恶劣的问题,提出一种可自浮拖航的六筒型综合平台基础结构。针对结构的自浮拖航过程,采用模型试验的方法对航速和吃水对其拖航过程中的各舱舱压、横纵摇倾角度以及拖航阻力的影响进行研究。结果表明：随着航速的增加,筒型基础的舱压变化增大,在实际拖航过程中应注意对舱压变化较大的舱室进行补气调平,保证足够的拖航稳定性;不同航速和吃水下的筒型基础浮运过程的横纵摇角均在-3°~1°范围内波动;拖航阻力受航速和吃水的影响较为明显,在相同吃水下,航速从0.3 m/s增加到0.4 m/s时,对应的拖航阻力平均值约增大1倍。
Abstract
Aiming at the complex and bad environment of offshore energy development, this paper proposes a six-bucket foundation structure that can be used for self-floating towing. The model test method is used to explore the influence of towing speed and draft on the response of the towing motion for bucket foundation during the towing process. The results show that, with the increase of towing speed, the change of the cabin pressure of the foundation increases. In the actual towing process, attention should be paid to the air supply and leveling of the tanks with large tank pressurechange to ensure sufficient towing stability. The roll angle of the floatation process at different speeds and draughts fluctuates within 3°. The towline force is significantly affected by the speed and draught. Under the same draught, when the towing speed increases from 0.3 m/s to 0.4 m/s, the average value of the towing resistance is approximately doubled.
