摘要
饱和潜水高压逃生艇是处于高压状态下的潜水人员撤离时采用的载具。结合有关规范的要求论述饱和潜水高压逃生艇的主要设计特征,对艇体的完整稳性和浸水稳性进行分析。结合高压逃生艇全封闭、大吃水和高重心的特征,对艇体的自扶正特征和晕船问题进行探究。结果表明:对于相似艇体外形,仅重心高度会对自扶正时间有影响;高压逃生艇在波浪中的人员晕船率较高,在高海况下降低部分航速能有效降低晕船率。
The Self-Propelled Hyperbaric Lifeboat(SPHL)used in saturation diving is a dedicated vehicle for the evacuation of divers under high pressure.The paper discusses its main design features according to the rules and regulations,and analyses its intact stability and flooded stability.The self-righting features and the Motion Sickness Incidence(MSI)of SPHL are investigated based on the characteristics of enclosed hull,large draft and high gravity center.It is found that the self-righting time is only influenced by the height of gravity center in case the hull shapes are similar.The high MSI in heavy waves can be reduced effectively by reducing speed.
