当前浮式平台船体结构分析的方法与重点综述(英文) 总被引:2,自引:0,他引:2
浮式平台概念的选择及其结构设计是深水工程项目的关键环节之一.它决定了平台在波浪载荷作用下的动力学响应、立管在深水条件下的运动以及进行平台建造与安装的技术难度等.结构强度、结构的抗疲劳性能以及结构的整体和局部稳定性能是浮式平台设计必须重点考虑的三个主要方面.总结了当前浮式平台设计的主要方法和它的主要任务以及技术要求,着重分析了设计过程中的主要技术难点及重点;最后,讨论了浮式平台结构设计的潜在发展趋势. 相似文献

在粘土、粉土等软土地基上建造重力式码头,必须进行可靠的地基加固处理,费用一般较高,故相应的工程实例比较少。文章以西非某泻湖内港口扩建项目为例,提出采取深水开挖深槽换填中粗砂并振冲加固地基可满足建造大型沉箱重力式码头需求。实践中总结出深水开挖超深换填砂基槽及其防淤控淤技术,深水回填砂技术及前后砂样变化特性、深水振冲砂技术及效果特征、最佳振冲参数、码头沉降特性等。 相似文献

随着我国经济快速发展,沿海港口吞吐量大幅增长,运输船舶不断大型化,同时随着"一带一路"建设的推进,越来越多的外海深水码头需要建造,而外海中长周期波条件下的桩基施工是公认的技术难题。文章依托以色列Ashdod港口项目,分析了外海桩基施工的技术难点,开展了桩顶支撑步履式沉桩技术研究,该技术将步履式自平衡顶推技术引入码头桩基施工,消除了涌浪对施工平台影响,创新了外海桩基施工技术,为今后类似工程项目的顺利实施提供借鉴。 相似文献

This paper proposes a tool to estimate crew composition based on safety/operational and financial requirements. As there is
a tendency of ship owners to implement improved technologies on board their vessels, there is no systematic way to predict
their potential effect on crew size and composition (typically determined by flag state authorities on a case-to-case basis)
nor on the type and complexity of on board duties new technologies might dictate. The main aim of this paper is to develop
a tool to assist in determining crew composition, by taking into account both administration’s and the ship owner’s point
of view. Based on data collected from ship owners, a data mining technique is implemented in order to form a generalized framework
that estimates crew composition as a function of ship type, size, and degree of automation. The agreement of model predictions
with records from specific (vessel) cases is very good in terms of safety (for operations such as watchkeeping, mooring/unmooring,
loading/unloading). The specific intended use of this tool is to help a ship owner decide whether it is cost-beneficial to
retrofit a conventional vessel with advanced technologies that would potentially entail a reduced crew (probably dealing with
different and more complex on board duties). Its main benefits are that it can be used to estimate crew composition before
any vessel construction or upgrade has actually taken place and that it allows crew composition to be easily adapted to the
technological evolution of ship systems even at their current rapid pace. 相似文献

The Japan Marine Science and Technology Center (JAMSTEC) has been, and is now promoting the “OD21” program (i.e., “Ocean
drilling in the 21st century”). This is the first plan in the world to utilize deep-water riser-drilling technologies for
scientific drilling. One of the important factors for the success of this program is the development of a high-performance
drilling vessel. Since 1990, JAMSTEC has been continuing a technological study of a riser-drilling vessel for scientific studies
with an operational capability in waters up to 4000 m deep. It was decided to start the construction with a two-phase plan:
a vessel with a riser operation for waters up to 2500 m deep will be constructed in the initial stage, and then the vessel
will be modified to a 4000-m depth capability. In the development process of the vessel, named Chikyu, many new technical developments have taken place, such as drilling/coring equipment, a dynamic positioning system, etc.
Thus, the Chikyu is expected to contribute to ocean engineering and other work, in addition to scientific advances.
