张力腿平台对水深具有高度敏感性,随水深变化,垂直面内的运动受到显著影响。对于超深水情况,对张力筋腱的设计提出更高的要求。为了改善这一状况,提出了一种新概念张力腿平台设计方案——Tension Based Tension Leg Platform(TBLP),它可以成倍地增加TLP适用的水深范围。对于已经使用的中等水深下的传统型的TLP,通过增加张力基底,就可以将其使用于更深的海域。针对这一新型TBLP概念,对典型的传统型TLP和TBLP水动力性能进行了初步分析比较,得出TBLP优于常规设计的水动力性能。
The tension leg platform is highly sensitive to water depth and varies significantly with depth, with vertical movement significantly affected. For ultra-deep water conditions, the design of tendon tendons put forward higher requirements. In order to improve this situation, a new concept of tension leg platform design (TBLP) is proposed, which can double the range of water depth suitable for TLP. For conventional TLPs that have been used at moderate depths, they can be used in deeper waters by adding tensioned substrates. Aiming at this new concept of TBLP, the hydrodynamic performance of typical traditional TLP and TBLP is analyzed and compared, and the hydrodynamic performance of TBLP is better than that of conventional design.
