摘要

摘要根据DNV-ST-0111一级标准,提出了一种动态定位船舶各执行机构推力优化分配的有效方法。优化任务近似为具有线性约束的凸问题,在数学上表示为二次规划。案例研究被用来说明在评估救援船的DP能力时所提出的方法的使用。基于二次规划的动态定位能力评估方法可以快速计算并对不同船舶设计进行定性比较。与DNV工具相比,该工具对带有方位推进器的船舶进行了100%的成功验证,而对带有方向舵的螺旋桨船舶则给出了悲观的解决方案。因此,它可以安全地应用于早期设计阶段。

Dynamic Positioning Capability Assessment Based on Optimal Thrust Allocation
Abstract The article presents an efficient method of optimal thrust allocation over the actuators in a dynamically positioned ship, according to the DNV-ST-0111 standard, Level 1. The optimisation task is approximated to a convex problem with linear constraints and mathematically formulated as quadratic programming. The case study is being used to illustrate the use of the proposed approach in assessing the DP capability of a rescue ship. The quadratic programming-based approach applied for dynamic positioning capability assessment allows for fast calculations to qualitatively compare different ship designs. In comparison with the DNV tool, it gives 100% successful validation for a ship with azimuth thrusters and a pessimistic solution for a ship equipped with propellers with rudders. Therefore, it can be safely applied at an early design stage.
