Environmental Forces on Offshore Structures

在海洋工程中使用的船舶和结构可以用系泊系统固定，但随着结构进入更深的水域，这可能变得不切实际。在深水中，主动系统是一种实用的替代解决方案，其中动力推进器将结构固定在原位。设计和分析这些主动系统需要一套额外的技术，而不仅仅是用于系泊系统的技术，其中包括预测由环境力（风、波浪和电流）产生的力和力矩的方法，以及分配推力到每个设备以平衡这些力和力矩的系统。DSA已经开发了一系列用于分析海上结构系泊力的软件工具，但在分析动力定位系统方面存在差距。纪念大学的研究人员将与dsaat的工程师合作，为他们提供风、流和波浪漂移力预测和推力分配方法的验证结果。这些新功能将使DSA能够将其客户群扩展到用于能源勘探和生产的海上结构市场，并为世界各地的游轮运营商、海军和海岸警卫队提供支持。

Ships and structures used in ocean engineering may be held in place with mooring systems, but as thestructures move into deeper water this may become impractical. An active system where the structure is held inplace by powered thrusters is a practical alternative solution for deep water. Designing and analyzing theseactive systems requires an additional set of techniques beyond those used for mooring systems, which includemethods of predicting the forces and moments created by the environmental forces (wind, waves and current),and a system for allocating thrust to each device to balance these forces and moments. DSA has developed aseries of software tools for anlayzing mooring forces for offshore structures, but sees a gap in its capacity foranalyzing dynamic positioning systems. Researchers at Memorial University will work with engineers at DSAto provide them with validated results for wind, current and wave drift force predictions and a thrust forceallocation method. These new features will allow DSA to expand its client base into the markets for offshorestructures used for energy exploration and production as well as support cruise ship operators, navies andcoastguards around the world.
