主推进系统实船训练系统的研究与实现

实船训练系统是嵌入舰船系统内的舰员训练模拟系统，具有实施容易，效率高和费用低的特点，能帮助舰员迅速获得必要的操作技能和知识。实船模拟训练，将成为未来海军训练的发展方向。现从国内外实船训练系统研究现状出发，分析了实船训练系统在舰员培训中的优势，提出了一种在主推进装置监控系统中嵌入实船训练的方案，使主推进系统带有模拟训练的功能。在海上停航或者在港内停泊期间，舰船主推进系统可以从航行模式切换到实船训练模式，舰员在平时工作环境中，学习主推进系统的各项操作和故障处理，使训练好像在航行中实际操作一样。舰船准备起航时，主推进系统能够迅速从训练模式切换到航行模式，执行原机舱监控系统的功能。实船训练系统不影响舰船航行中的操作功能，也不会降低原机舱监控系统的性能。

Mechanical model and characteristics of deep-water drilling riser-wellhead system under internal solitary waves

Internal solitary waves with a huge amount of energy easily trigger the large dynamic responses of riser-wellhead system and threaten its structural safety. However, previous studies have only focused on the dynamic response of the riser under internal solitary waves. The riser may experience excessive traction from the platform, especially from the mooring platform, in response to the arrival of internal solitary waves. The bottom of the riser connects to the wellhead system, which in turn exerts a reaction force on the riser. To address this problem, a coupled dynamic model of deep-water drilling mooring platform-riser-wellhead system under internal solitary waves is developed in this paper. A dynamic response analysis method based on the fourth-order Runge-Kutta method and finite element method is also proposed for the mooring platform-riser-wellhead system. A dynamical solver for the coupled system is then developed using MATLAB. The dynamic response characteristics of the riser-wellhead system under internal solitary waves are calculated. Results show that the displacement and bending moment of the system initially increases and then decreases along with the propagation of internal solitary waves, and finally reach equilibrium position. The displacement and bending moment reach their peak before the trough of internal solitary waves passes through the riser-wellhead system. The dynamic responses of the riser-wellhead system under the influence of internal solitary wave loads are much larger than those without the effect of internal solitary wave loads. The riser system experiences shearing loads at the interface of internal solitary waves, which trigger a step-like bending moment variation. The bending moment of the conductor under the mudline is greatly increased by the internal solitary waves.
