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.

海洋工程中使用的船舶和结构物可以用系泊系统固定，但随着结构物进入深水，这可能变得不切实际。一个主动系统，其中的结构是由动力推进器保持在适当的位置是一个实用的替代解决方案，深水。设计和分析这些主动系统需要一套额外的技术，超出了用于系泊系统的技术，包括预测环境力（风、波浪和水流）产生的力和力矩的方法，以及为每个设备分配推力以平衡这些力和力矩的系统。DSA已经开发了一系列软件工具来分析海洋结构物的系泊力，但在分析动力定位系统的能力上还存在差距。纪念大学的研究人员将与DSA的工程师合作，为他们提供风、海流和波浪漂移力预测的验证结果以及推力分配方法。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，并支持世界各地的游轮运营商，海军和海岸警卫队。
