Although there have been many instances of ship collision at sea in recent times, not much research has been conducted on the topic. In this study, paint from an actual site of ship collision was collected and analyzed as evidence. The amount of evidence collected from the ships involved in the collision is either small or has inconsistent morphology. In addition, the contaminants and samples are often mixed in this evidence, making its analysis difficult. Paint traces of the damaged ship and the ship suspected to be responsible for the collision were compared through scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS), attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR), thermogravimetry (TG) and derivative thermogravimetry (DTG), and pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) analyses. The ship responsible for the collision could be identified by characterization and by performing a comparative analysis of the extracted paint. Among the methods used in this study, Py-GC/MS can sensitively analyze even similar paints, and identified styrene and phthalic anhydride as the most prominent components of the paint used as evidence. The results obtained can be used to investigate the evidence collected from collision sites and to determine the ship responsible for the collision.
尽管近年来海上发生了许多船舶碰撞事件，但针对该主题的研究却不多。在本研究中，收集并分析了来自实际船舶碰撞现场的油漆作为证据。从碰撞涉及的船舶上收集到的证据数量要么很少，要么形态不一致。此外，在这些证据中，污染物和样本常常混合在一起，这使得对其进行分析变得困难。通过扫描电子显微镜与能量色散X射线光谱仪（SEM-EDS）、衰减全反射傅里叶变换红外光谱仪（ATR-FTIR）、热重分析法（TG）和微商热重分析法（DTG）以及热解气相色谱/质谱联用仪（Py-GC/MS）分析，对受损船舶和疑似造成碰撞的船舶的油漆痕迹进行了比较。通过对提取的油漆进行表征和对比分析，可以确定造成碰撞的船舶。在本研究使用的方法中，Py-GC/MS甚至可以灵敏地分析相似的油漆，并确定苯乙烯和邻苯二甲酸酐是用作证据的油漆中最主要的成分。所得结果可用于调查从碰撞现场收集到的证据，并确定造成碰撞的船舶。
