This paper describes the SPOWTT project. The intention of this project was to understand how sailing by crew transfer vessel (CTVs) to offshore wind farms affects the mental and physical wellbeing of individuals on board. The focus was on quantifying this impact, understanding the key drivers, with an aim to ensuring personnel can arrive to the wind turbines in a fit state to work safely and effectively. Impacts looked at subjective state beyond simply vomiting. Key results include the ability now to predict vessel motions from given Metocean conditions and vessel designs. We also discovered that the impact of vessel motions on seasickness is different for different symptoms and is driven not only by vertical z-axis accelerations but also by certain frequencies of motion in the y-axis. Frequencies other than 0.16 Hz were found to be impactful, and x-axis movements appeared to have a longer-lasting effect on the day's work. Through the formulation of a new, evidence-based understanding of seasickness, we have created an operational planning tool, designed to have a direct benefit on the safety and productivity of offshore wind farm operations.

SPOWTT：提高海上风电技术人员运输的安全性和生产力

本文介绍了 SPOWTT 项目。该项目的目的是了解船员转运船 (CTV) 航行到海上风电场如何影响船上个人的身心健康。重点是量化这种影响，了解关键驱动因素，以确保人员能够以合适的状态到达风力涡轮机，以安全有效地工作。Impacts 着眼于主观状态，而不仅仅是呕吐。主要结果包括现在能够根据给定的 Metocean 条件和船舶设计预测船舶运动。我们还发现，血管运动对晕船的影响是不同的症状不同，并且不仅受垂直ž -轴加速度，而且通过在运动的某些频率ÿ-轴。发现 0.16 Hz 以外的频率具有影响力，并且x轴运动似乎对一天的工作有更持久的影响。通过形成对晕船的新的、基于证据的理解，我们创建了一个运营规划工具，旨在直接提高海上风电场运营的安全性和生产力。
