To decrease Europe's harmful emissions, the European Union aims to substantially increase its offshore wind energy capacity. To further develop offshore wind energy, investment in ever-larger construction vessels is necessary. However, this market is characterised by seemingly unpredictable growth of market demand, turbine capacity and distance from shore. Currently it is difficult to deal with such market uncertainty within the ship design process. This research aims to develop a method that is able to deal with market uncertainty in early ship design by increasing knowledge when design freedom is still high. The method uses uncertainty modelling prior to the requirement definition stage by performing global research into the market, and during the concept design stage by iteratively co-evolving the vessel design and business case in parallel. The method consists of three parts; simulating an expected market from data, modelling multiple vessel designs, and an uncertainty model that evaluates the performance of the vessels in the market. The case study into offshore wind foundation installation vessels showed that the method can provide valuable insight into the effect of ship parameters like main dimensions, crane size and ship speed on the performance in an uncertain market. These results were used to create a value robust design, which is capable of handling uncertainty without changes to the vessel. The developed method thus provides a way to deal with market uncertainty in the early ship design process.

探索早期船舶设计中的市场不确定性

为了减少欧洲的有害排放,欧盟旨在大幅增加其海上风能容量。为了进一步开发海上风能,投资更大的建筑船舶是必要的。然而,这个市场的特点是市场需求、涡轮机容量和离岸距离的增长看似不可预测。目前很难在船舶设计过程中处理这种市场不确定性。本研究旨在开发一种能够在设计自由度仍然很高的情况下通过增加知识来应对早期船舶设计中的市场不确定性的方法。该方法在需求定义阶段之前通过对市场进行全球研究来使用不确定性建模,在概念设计阶段通过迭代地并行地共同发展船舶设计和业务案例。该方法由三部分组成;根据数据模拟预期市场,对多种船舶设计进行建模,以及评估市场中船舶性能的不确定性模型。对海上风电基础安装船的案例研究表明,该方法可以提供有价值的见解,了解船舶参数(如主要尺寸、起重机尺寸和船速)在不确定市场中对性能的影响。这些结果用于创建价值稳健的设计,该设计能够在不改变容器的情况下处理不确定性。因此,开发的方法提供了一种在早期船舶设计过程中处理市场不确定性的方法。以及评估船舶在市场上的表现的不确定性模型。对海上风电基础安装船的案例研究表明,该方法可以提供有价值的见解,了解船舶参数(如主要尺寸、起重机尺寸和船速)在不确定市场中对性能的影响。这些结果用于创建价值稳健的设计,该设计能够在不改变容器的情况下处理不确定性。因此,开发的方法提供了一种在早期船舶设计过程中处理市场不确定性的方法。以及评估船舶在市场上的表现的不确定性模型。对海上风电基础安装船的案例研究表明,该方法可以提供有价值的见解,了解船舶参数(如主要尺寸、起重机尺寸和船速)在不确定市场中对性能的影响。这些结果用于创建价值稳健的设计,该设计能够在不改变容器的情况下处理不确定性。因此,开发的方法提供了一种在早期船舶设计过程中处理市场不确定性的方法。这些结果用于创建价值稳健的设计,该设计能够在不改变容器的情况下处理不确定性。因此,开发的方法提供了一种在早期船舶设计过程中处理市场不确定性的方法。这些结果用于创建价值稳健的设计,该设计能够在不改变容器的情况下处理不确定性。因此,开发的方法提供了一种在早期船舶设计过程中处理市场不确定性的方法。
