The motions of vessels may interfere with crew activities and well-being, but the relationships between motion and the experiences of crew are not well-established. Crew responses to motions of a floating production and storage offshore vessel at a fixed location in the North Sea were studied over a 5-month period to identify any changes in crew difficulties and symptoms associated with changes in vessel motion. Ship motions in all six axes (fore-aft, lateral, vertical, roll, pitch, and yaw) were recorded continuously over the 5-month period while 47 crew completed a total of 1704 daily diary entries, a participation rate of 66-78% of the crew complement. The dominant oscillations had frequencies of around 0.1 Hz, producing magnitudes of translational oscillation in accommodation areas of up to about 0.7 ms(-2)r.m.s., depending on the weather, and magnitudes up to three times greater in some other areas. The daily diaries gave ratings of difficulties with tasks, effort level, motion sickness, health symptoms, fatigue, and sleep. Problems most strongly associated with vessel motions were difficulties with physical tasks (balancing, moving and carrying), and sleep problems. Physical and mental tiredness, cognitive aspects of task performance, and stomach awareness and dizziness were also strongly associated with motion magnitude. There was a vomiting incidence of 3.1%, compared with a predicted mean vomiting incidence of 9.3% for a mixed population of unadapted adults. It is concluded that crew difficulties increase on days when vessel motions increase, with some activities and responses particularly influenced by vessel motions.
船舶的运动可能会干扰船员的活动和健康，但船舶运动与船员体验之间的关系尚未得到充分确立。本研究在北海的一个固定位置对一艘浮式生产储卸油船（FPSO）上的船员进行了为期 5 个月的研究，以确定船员在运动状态下的困难和症状是否发生了变化。在 5 个月的时间里，船舶在六个轴（前后、左右、垂直、横摇、纵摇和偏航）的运动被连续记录，同时 47 名船员总共完成了 1704 份每日日记记录，参与率为船员总数的 66-78%。主要的振动频率约为 0.1 Hz，在住宿区产生的平移振动幅度高达约 0.7 ms(-2)r.m.s.，这取决于天气，而在其他一些区域的振动幅度高达三倍。每日日记记录了完成任务的难度、努力程度、晕船、健康症状、疲劳和睡眠等方面的情况。与船舶运动最相关的问题是物理任务（平衡、移动和搬运）以及睡眠问题。身体和精神疲劳、任务表现的认知方面以及胃部不适和头晕也与运动幅度密切相关。呕吐的发生率为 3.1%，而未适应的混合人群预计的平均呕吐发生率为 9.3%。研究得出的结论是，当船舶运动增加时，船员的困难也会增加，某些活动和反应特别容易受到船舶运动的影响。
