摘要
全球贸易的快速发展推动了航运业船舶设计和建造技术的革新,促进了大型海上设施和船舶建造,以支持资源开发和海洋经济的发展。然而,这也引发了诸多安全问题,其中船舶在靠泊和系泊作业时对码头平台造成的过载尤为突出,严重时可导致码头平台破损及船舶严重变形。因此,研究船舶在靠泊和系泊工况下码头平台受到的极值载荷至关重要。该文以2艘“中远盛世号”滚装船为研究对象,针对码头平台进行转运作业的场景(一艘船系泊在码头平台一侧,另一艘船以不同泊速同时进行靠泊),通过建立船舶、护舷球和码头平台的数值模型,并考虑复杂的风浪流环境载荷条件,基于ANSYS双模块AQWA和LS-DYNA建立了码头平台在船舶靠泊和系泊联合工况下极值载荷的预测方法。该方法为船舶安全靠泊和系泊码头平台提供了理论依据和设计参考,有助于预防码头平台过载事故,提高安全阈值。
With the rapid development of global trade,the innovation of ship design and construction technology in the shipping industry has been promoted.So that many countries have built more large-scale offshore facilities and ships for resource development and the development of marine economy,but it has also produced a lot of safety problems,mainly because of the overload of the ship on the dock platform when berthing is particularly prominent,which can lead to the damage of the dock platform and the serious deformation of the ship in serious cases.It is particularly important to study the extreme load of the dock platform under the mooring condition of the ship.Two COSCO Shengshi ro-ro ships during transshipment operations are investigated in this study,with one vessel moored alongside the dock while the other simultaneously berths at varying speeds.By establishing numerical models of the ship,fender balls and the dock platform,and accounting for complex environmental loads from wind,waves,and currents,the prediction method of the extreme load of the dock platform under the berthing and mooring condition of the ship is established based on the ANSYS dual module AQWA and LS-DYNA.This method provides reasonable and safe opinions for the ship to berth the dock platform.It is beneficial to reduce the overload of the terminal platform and improve the safety threshold.
