主动式升沉补偿技术研究现状和发展趋势

Current status and development tendency of active heave compensation system

随着深海能源的开发,深海更加恶劣的环境使海上作业窗口期缩短,主动式升沉补偿装置可以有效解决深海作业窗口期短的问题,保障深海作业的安全,提高深海作业的效率,具有很高的经济价值。本文介绍主动式升沉补偿系统的组成及工作原理,总结主动式升沉补偿系统的响应滞后、参数时变、随机性、非线性4个技术难点,分析目前的研究思路,指出优点及其不足之处,并根据工业需求提出技术发展趋势。

With exploitation of deep-sea energy, harsh environment of the deep-sea shortens the weather window period of offshore operations. Active heave compensation system can effectively solve this problem, which ensures operation safety and improves operation efficiency to obtain higher economic benefit. This paper introduces the composition and working principle of the active heave compensation system. The technical challenges for development of the active heave compensation system are summarized including response lag, parameter time-varying, stochastic and nonlinear properties. The solutions to these challenges are analyzed based on the existing research schemes from aspects of its advantages and disadvantages. The state of the art of active heave compensation products are summarized. The development trends of active heave compensation are suggested according to the technical requirements.
