摘要
工程船舶在海上作业时都需配备定位系统,如何配置安全可靠、满足作业要求和具有市场竞争力的锚泊定位系统已成为探讨热点。通过对现行锚泊定位系统分析的几种基本方法的理论特点及应用特性比较,确定应用准动态方法对工程船进行锚泊定位分析的可行性,并阐述了准动态分析方法的基本理论及特点,与全动态分析方法进行了理论对比分析,从而进一步体现了准动态方法应用于工程船舶锚泊定位的合理性。以某工程船为例,分别应用准动态分析软件ARAINE及全动态分析软件DEEPC进行锚泊定位计算对比分析,论证了应用准动态方法分析工程作业船舶锚泊定位的优势及特点。从理论分析及实际应用角度充分证明了,应用准动态方法对工程船进行锚泊定位分析既保证工程精度要求,又可显著提高计算效率,具有明显优势。
Offshore engineering vessels are equipped with positioning system in offshore operations. Configuration of a mooring positioning system which is safe, reliable and satisfies the requirements of operation and market competitiveness has become a hot topic. Based on the comparison of the theoretical and application characteristics of several basic methods adopted by current mooring positioning systems, the feasibility of using quasi-dynamic method for engineering vessel mooring positioning system analysis is ascertained, its basic principle and characteristics are elaborated and compared theoretically with dynamic analysis method to further demonstrate the rationality of applying the quasi-dynamic method. Taking an engineering vessel for example, the mooring positioning calculations are compared and analyzed between the quasi-dynamic analysis software ARIANE and the dynamic analysis software DEEPC, the advantages and features of quasi-dynamic analysis method for engineering operation vessel mooring positioning are verified. It is well proved through theoretical analysis and practical applications that quasi-dynamic method can not only guarantee the engineering accuracy requirement, but also can significantly improve the computational efficiency, therefore it has obvious advantages.
