Thresholds that guide diagnoses of probable and acceptable seasickness levels on board ships are scarcely reported in literature. Motion sickness incidence and motion sickness dose value thresholds exist, but are defined for specific environments, such as naval, or offered merely as optional criteria for ship performance metrics. The presented work communicates a novel means of developing seasickness diagnostic criteria during ship operation, based on observations from shipboard measurement systems and seafarers using an innovative platform. The innovative platform provides personalised seasickness criteria that are accessible during ship operation to estimate the probable level of seasickness on board. Results are compared to that from a traditional method of data acquisition and analyses, post operation, revealing a similar trend in diagnostic threshold magnitudes (13-85 m/s) that can be applicable to voyages with different durations (0.5-6 hr) considering desired levels of seasickness (10-50 %). The seasickness criteria are envisioned to be pertinent for the prediction of probable seasickness levels based on sea state forecasts and ship motion estimation.
在文献中，几乎没有报道用于指导船舶上可能的和可接受的晕船水平诊断的阈值。运动病发病率和运动病剂量值阈值是存在的，但它们是针对特定环境（如海军）定义的，或者仅仅作为船舶性能指标的可选标准。本工作通过利用创新平台，基于船舶测量系统和海员的观测，提出了一种在船舶运行期间开发晕船诊断标准的新方法。该创新平台提供了个性化的晕船标准，在船舶运行期间可以使用这些标准来估计船上晕船的可能程度。将结果与传统的操作后数据采集和分析方法进行比较，结果显示，在诊断阈值幅度（13-85m/s）上存在相似的趋势，这对于不同持续时间（0.5-6 小时）的航程（10-50%）来说是可以适用的，考虑到期望的晕船水平。这些晕船标准预计可以根据海况预报和船舶运动估计来预测可能的晕船水平。
