The main objective with subsea mechanical dispersion (SSMD) is to influence the fate of an oil spill in the marine environment by significantly reducing oil droplet sizes from subsea release of oil. Earlier studies have indicated that the capability of SSMD to reduce oil droplet sizes is comparable to subsea dispersant injection (SSDI). Earlier testing of SSMD has mainly used a low viscus paraffinic oil. Focus for this study was to study SSMD and SSDI effectiveness using five oil types spanning out a wide variation of relevant oil properties. Effectiveness was quantified as the reduction in oil droplet sizes measured by a Silhouette camera. Testing of the two technologies were completed in the same experiment on a simulated subsea release. The results show a variation in effectiveness for both technologies as a function of oil properties. SSMD and SSDI showed comparable effectiveness for all oils tested.
海底机械分散（SSMD）的主要目标是通过从海底释放油来显著减小油滴尺寸，从而影响海洋环境中溢油的命运。早期研究表明，SSMD 减小油滴尺寸的能力可与海底分散剂注入（SSDI）相媲美。早期的 SSMD 测试主要使用低粘度石蜡油。本研究的重点是使用五种油类研究 SSMD 和 SSDI 的有效性，这些油类涵盖了广泛的相关油类性质变化。有效性通过 Silhouette 相机测量的油滴尺寸减小来量化。在模拟海底释放的同一实验中完成了这两种技术的测试。结果表明，这两种技术的有效性都随油性质的变化而变化。SSMD 和 SSDI 对所有测试的油都显示出相当的有效性。
