绞吸挖泥船新型施工定位方式的探讨及优化

通过对绞吸挖泥船几种常用定位形式的探讨,提出一种双锚四缆单桩定位施工方法,该方法集钢桩定位和三缆定位的优点于一身,既能缩短倒桩进船时间,又能提高挖泥生产效率,使操作更平稳、设备更安全.     

浅谈绞吸船挖岩工况下串锚加延长锚施工工艺

绞吸船移动横移锚是挖泥施工的必需操作,若移锚操作质量不高,将降低船舶时利率及日产量。在一些特殊工况下,传统横移锚抛设方法已不能满足施工需要。在巴基斯坦某疏浚吹填挖岩工程中,通过串锚加延长锚定位锚系统工艺,成功克服了横移锚"走锚"问题,大大提高了经济效益。     

靠船墩可靠性设计方法

通过对靠船墩三维结构随机力学分析,提出基于可靠度理论下的靠船墩设计方法,可直接应用于工程实践     

LNG码头靠船墩布置

LNG码头平面设计中,最为重要的是靠船墩位置的设计。针对常规靠船墩位置的设计是按照规范的系数要求选取的,但较难适应所有LNG船型的靠泊。研究如何提高靠船墩对各种LNG船的靠泊适应性：分析LNG船的仓容分布、储罐类型和外型特点,介绍LNG船靠泊准则,并结合某海外1万～22万m3LNG码头工程论述靠船墩的布置。得出如下结论：合理的靠船墩位置不是关于工作平台对称的,而应适当增加船尾方向的靠船墩与工作平台的距离。
